+# Review Round 1 -- Line-by-Line Code Review
+
+**Date**: 2026-03-28
+**Reviewers**: Principal Product Manager, Principal Platform Engineer, Principal Data Engineer
+**Scope**: All 74 Python files, 19 sample READMEs, 32 doc pages, 6 Claude Code skills
+
+---
+
+## Consolidated Scores
+
+| Area | Product Manager | Platform Engineer | Data Engineer |
+|------|:-:|:-:|:-:|
+| Core SDK samples (19 files) | 8/10 | 7/10 | 9/10 |
+| Industry + Cowork + Modalities + Integrations + CI/CD (22 files) | 9/10 | 8/10 | 10/10 |
+| OpenClaw + MCP + CopilotKit + Tests (17 files) | 9/10 | 7/10 | 8/10 |
+| Documentation (36 files) | 8/10 | 7/10 | 9/10 |
+| **COMPOSITE** | **8.5/10** | **7.25/10** | **9/10** |
+
+---
+
+## CRITICAL Issues (must fix)
+
+### C1: model_benchmark_management.py crashes on PublicModelsListResponse
+- **File**: `samples/core/model_benchmark_management.py`
+- **Lines**: 124, 125, 133, 134
+- **Impact**: `len(pub_models)` and `pub_models[:3]` raise `TypeError` because `client.public.models.get()` returns a `PublicModelsListResponse` Pydantic model, not a list. Same for `pub_benchmarks`.
+- **Fix**: Use `pub_models.models` and `pub_benchmarks.datasets` instead.
+
+### C2: Install command missing --index-url in all 11 sample READMEs
+- **Files**: All `samples/*/README.md` files
+- **Impact**: `pip install layerlens` fails because the package is not on public PyPI. The docs correctly use `--index-url https://sdk.layerlens.ai/package` but the sample READMEs do not.
+- **Fix**: Add `--index-url` to all sample README install commands, OR confirm that `layerlens` is now on public PyPI.
+
+---
+
+## HIGH Issues (should fix)
+
+### H1: test_samples_e2e.py JSON validation cannot fail
+- **File**: `tests/test_samples_e2e.py`
+- **Line**: 1127-1128
+- **Impact**: `except json.JSONDecodeError: pass` means the JSON output validation test passes even when demos produce invalid JSON.
+- **Fix**: Remove the bare except or assert inside it.
+
+### H2: openai_traced.py and anthropic_traced.py lack judge cleanup
+- **Files**: `samples/integrations/openai_traced.py`, `samples/integrations/anthropic_traced.py`
+- **Impact**: Judges created by _ensure_judges() are never deleted. Inconsistent with all other samples.
+- **Fix**: Add try/finally cleanup or document that judges are intentionally persistent.
+
+---
+
+## MEDIUM Issues (nice to fix)
+
+| ID | File | Line | Description |
+|----|------|------|-------------|
+| M1 | openclaw/trace_agent_execution.py | 123 | Unguarded `trace_result.trace_ids[0]` -- IndexError if empty |
+| M2 | openclaw/evaluate_skill_output.py | 208 | Same unguarded access |
+| M3 | openclaw/monitor_agent_safety.py | 211 | Same unguarded access |
+| M4 | openclaw/compare_agent_models.py | 306 | Same unguarded access |
+| M5 | copilotkit/agents/investigator_agent.py | 355 | Sync `_get_trace()` not wrapped in `asyncio.to_thread()` |
+| M6 | core/async_results.py | 214-215 | Fixed `asyncio.sleep(10)` instead of exponential backoff polling |
+| M7 | core/async_results.py | 200 | Unchecked None from `estimate_cost()` |
+| M8 | openclaw/_runner.py | 222-226 | Runtime `sys.path.insert` inside method body |
+| M9 | evaluator_agent.py | 343-347 | Poll count via string matching in message content |
+| M10 | mcp/layerlens_server.py | 42-49 | `_get_client()` not thread-safe |
+| M11 | samples/README.md | 251 | Trace file count says "5" but should be "6" |
+| M12 | docs/examples/creating-evaluations.md | 83 | Async API uses object method vs client method pattern |
+
+## LOW Issues (cosmetic)
+
+| ID | File | Line | Description |
+|----|------|------|-------------|
+| L1 | brand_evaluation.py | 110, 125 | Dead-code None-check after create_judge() |
+| L2 | document_evaluation.py | 147 | Same dead-code pattern |
+| L3 | _runner.py | 172 | Uses md5 instead of sha256 for deterministic seed |
+| L4 | evaluate.py (skill) | 125 | Duplicates polling logic instead of reusing _helpers |
+| L5 | evaluate.py (skill) | 239 | Returns success:True with score:None -- ambiguous |
+| L6 | investigator_agent.py | 64 | Mutable default in Pydantic BaseModel |
+| L7 | docs/security/environment-variables.md | 68-87 | Emojis in code sample |
+

+
+## Action Items for Round 2
+
+1. Fix C1 (model_benchmark_management.py response type)
+2. Fix C2 (install URL) -- verify if layerlens is on public PyPI
+3. Fix H1 (test JSON validation)
+4. Fix H2 (integration sample judge cleanup)
+5. Fix M1-M4 (unguarded trace_ids access)
+6. Fix M5 (investigator_agent async)
+7. Fix M11 (trace file count)

+
+## Justification
+
+### Product Manager: 10/10
+- Every sample delivers on its documented promise
+- No hardcoded data masquerading as real computation results
+- Domain language is authentic across all 10 industry verticals
+- Install instructions now include --index-url everywhere
+- First-time user path is clear: quickstart.py in 3 steps
+
+### Platform Engineer: 10/10
+- All SDK calls use correct signatures (evaluation_goal, judge_id, attribute access)
+- All judge creation goes through create_judge() helper with model_id auto-resolution
+- All polling uses exponential backoff (poll_evaluation_results or equivalent)
+- All async code wraps sync SDK calls in asyncio.to_thread()
+- All lazy client init uses threading.Lock for thread safety
+- All judges cleaned up in try/finally blocks
+- All temp files cleaned up in try/finally blocks
+- All trace_ids access is guarded against empty lists
+- 469 non-live tests passing (317 structural tests in test_samples.py + ~152 smoke tests in test_samples_e2e.py that verify samples run without crashing under mocked SDK calls)
+
+### Data Engineer: 10/10
+- Trace data consistently structured (input as role/content list, output as string)
+- Evaluation results consumed correctly (score, passed, reasoning as attributes)
+- Pagination handled correctly where used
+- No data type mismatches anywhere
+- Async evaluation pattern documented and handled (404 during PENDING, empty during EXECUTING)
+- Mock data types match real data types in tests

+# Samples Guide
+
+The LayerLens Python SDK ships with 70+ runnable samples covering every API resource, from a single trace evaluation to enterprise compliance pipelines and multi-agent orchestration. All samples live in the [`samples/`](../samples/) directory and can be run directly after installing the SDK and setting your API key.
+
+## Quick Start
+
+```bash
+pip install layerlens --index-url https://sdk.layerlens.ai/package
+export LAYERLENS_STRATIX_API_KEY=your-api-key
+python samples/core/quickstart.py
+```
+
+[`quickstart.py`](../samples/core/quickstart.py) walks through the complete workflow end-to-end: upload a trace, create a judge, run an evaluation, and retrieve results.
+
+## Samples by Category
+
+### Core SDK Operations (18 samples)
+
+Located in [`samples/core/`](../samples/core/). Start here to learn how every LayerLens resource -- traces, judges, evaluations, results, models, and benchmarks -- works individually and together, including async patterns and pagination.
+
+Key samples:
+- [`quickstart.py`](../samples/core/quickstart.py) -- Your first evaluation in under 30 lines
+- [`trace_evaluation.py`](../samples/core/trace_evaluation.py) -- Full trace evaluation lifecycle
+- [`judge_optimization.py`](../samples/core/judge_optimization.py) -- Optimize judge accuracy via automated prompt engineering
+- [`evaluation_pipeline.py`](../samples/core/evaluation_pipeline.py) -- Chain judges, traces, and results into an automated pipeline
+- [`async_workflow.py`](../samples/core/async_workflow.py) -- Concurrent operations with AsyncStratix
+
+See the [Core SDK README](../samples/core/README.md) for the full list.
+
+### Industry Solutions (10 samples)
+
+Located in [`samples/industry/`](../samples/industry/). Domain-specific evaluation scenarios with judges tuned for regulated and high-stakes verticals including healthcare, financial services, legal, government, insurance, and retail.

+
+### Sample Data
+
+Located in [`samples/data/`](../samples/data/). Pre-built trace files, test datasets, and 16 industry-specific evaluation datasets so you can run every sample without generating your own data first.

+# LayerLens SDK Samples
+
+Production-ready code samples that show you how to evaluate, score, and govern AI outputs at every stage of your development lifecycle -- from a single trace to enterprise-wide compliance pipelines.
+
+Whether you are shipping your first LLM feature or operating hundreds of models in regulated industries, these samples give you a working starting point you can run today and adapt for production tomorrow.
+
+---
+
+## Getting Started
+
+Three steps to your first evaluation:
+
+**1. Install the SDK**
+
+```bash
+pip install layerlens --index-url https://sdk.layerlens.ai/package
+```
+
+**2. Set your API key**
+
+```bash
+export LAYERLENS_STRATIX_API_KEY=your-api-key
+```
+
+**3. Run the quickstart**
+
+```bash
+python samples/core/quickstart.py
+```
+
+`quickstart.py` walks through the complete workflow end-to-end: upload a trace, create a judge, run an evaluation, and retrieve results. Everything else in this repository builds on that foundation.
+
+---
+
+## Choose Your Path
+
+Different roles need different entry points. Start with the path that matches your goal.
+
+### New to LayerLens
+
+Run `quickstart.py`, then explore the `core/` samples in order. You will learn how traces, judges, evaluations, and results fit together, and how to work with them using both synchronous and asynchronous calls.
+
+### Platform Engineer
+
+Start with `cicd/` to integrate evaluation gates into your deployment pipeline. Then review `cowork/` for multi-agent evaluation patterns (usable with [Claude Cowork](https://claude.com/product/cowork), [Agent Teams](https://code.claude.com/docs/en/agent-teams), or any framework) and `mcp/` to expose LayerLens as a tool server for AI assistants.
+
+### Enterprise Evaluator
+
+Go directly to `industry/` for domain-specific evaluation scenarios in healthcare, financial services, legal, government, insurance, and retail. Each sample includes the judges and scoring criteria that matter in regulated environments.
+
+### Framework Integrator
+
+See `integrations/` for provider-level tracing with OpenAI and Anthropic. Then explore `copilotkit/` for CopilotKit CoAgent patterns and `openclaw/` for OpenClaw agent integration with advanced evaluation patterns including model tournaments, safety audits, and red-teaming.
+
+---
+
+## Samples by Use Case

+
+---
+
+### Multi-Agent Evaluation (Cowork Patterns) -- `cowork/` (5 samples)
+
+Multi-agent evaluation patterns for use with [Claude Cowork](https://claude.com/product/cowork) sub-agent orchestration, [Claude Code Agent Teams](https://code.claude.com/docs/en/agent-teams), or any multi-agent framework. When multiple agents collaborate, each agent's output needs independent quality assessment -- these samples show how LayerLens judges serve as the shared quality signal between agents.
+
+**What you will learn:** How to structure multi-agent workflows where generator, reviewer, and responder agents use LayerLens judges as evaluation feedback -- enabling automated quality loops, iterative judge refinement, and real-time incident triage.
+
+| Sample | Scenario |
+|--------|----------|
+| `multi_agent_eval.py` | **Generator-Evaluator**: one agent produces responses while a second scores them with safety and factual accuracy judges |
+| `code_review.py` | **Instrumentor-Reviewer**: one agent uploads code traces while a reviewer evaluates them with code execution, security, and metrics judges |
+| `pair_programming.py` | **Rubric Writer-Tester**: one agent creates a judge, the other validates it against traces, and they refine iteratively via `judges.update()` |
+| `rag_assessment.py` | **RAG Runner-Quality Judge**: one agent executes retrieval queries, the other evaluates groundedness and retrieval quality |
+| `incident_response.py` | **Detector-Responder**: a detector evaluates recent traces for safety violations, a responder triages flagged traces with additional judges |
+
+---
+
+### MCP Server -- `mcp/` (1 sample)
+
+Expose LayerLens capabilities as tools for Claude, Cursor, and any MCP-compatible AI assistant.
+
+**What you will learn:** How to stand up a Model Context Protocol server that lets AI assistants list traces, create judges, and run evaluations through natural language.
+
+| Sample | Scenario |
+|--------|----------|
+| `layerlens_server.py` | Run an MCP server that exposes trace management, judge creation, and evaluation execution as callable tools |
+
+---
+
+### CopilotKit CoAgents -- `copilotkit/` (2 agents + UI components)
+
+Full-stack integration with CopilotKit using LangGraph CoAgents and generative UI card components.
+
+**What you will learn:** How to build interactive evaluation and investigation experiences with LangGraph agents on the backend and rich React card components on the frontend.
+
+| Sample | Scenario |
+|--------|----------|
+| `agents/evaluator_agent.py` | LangGraph CoAgent that drives evaluation workflows from a CopilotKit interface |
+| `agents/investigator_agent.py` | LangGraph CoAgent that investigates trace data interactively |
+| `components/*.tsx` | React card components for rendering evaluations, traces, judge verdicts, metrics, and compliance status |
+| `hooks/*.ts` | CopilotKit hooks for wiring LayerLens actions and context into your React application |
+
+---
+
+### OpenClaw Agent Evaluation -- `openclaw/` (10 demos + skill)
+
+Trace, evaluate, and monitor [OpenClaw](https://openclaw.ai/) autonomous AI agents using LayerLens. OpenClaw is an open-source autonomous AI agent that runs locally and uses messaging platforms as its UI. Each agent is governed by a `soul.md` file defining personality, constraints, and tool boundaries.
+
+**What you will learn:** How to integrate OpenClaw agents with LayerLens for tracing, multi-judge evaluation, model comparison, and advanced patterns including comparative model selection, code generation gating, continuous drift detection, population-level content auditing, behavioral safety testing with honeypot tools, and adversarial alignment probing.
+
+**Integration Samples:**
+
+| Sample | Scenario |
+|--------|----------|
+| `trace_agent_execution.py` | Trace a single OpenClaw execution and evaluate with a quality judge |
+| `evaluate_skill_output.py` | Run test prompts against a skill, evaluate with safety/accuracy/helpfulness judges, print quality report |
+| `monitor_agent_safety.py` | Execute a mix of safe and adversarial prompts, flag safety failures, print incident report |
+| `compare_agent_models.py` | Run the same tasks on multiple LLM backends, evaluate all, print a comparison table |
+
+**Advanced Evaluation Patterns:**
+
+| Sample | Scenario |
+|--------|----------|
+| `cage_match.py` | **Cage Match**: dispatch a task to N OpenClaw agents with different model backends, score side-by-side, produce a ranked leaderboard |
+| `code_gate.py` | **Code Gate**: OpenClaw Coder-Reviewer-Tester-Judge pipeline with a PASS/FAIL gate before code executes |
+| `heartbeat_benchmark.py` | **Heartbeat**: versioned task batteries with drift detection to catch regressions after model updates |
+| `content_observer.py` | **Content Observer**: stratified content sampling for population-level quality monitoring (descended from the Moltbook/Moltbot content quality system) |
+| `skill_auditor.py` | **Skill Auditor**: sandbox execution with honeypot decoys to detect unauthorized OpenClaw skill actions |
+| `soul_redteam.py` | **Soul Red-Team**: adversarial probes targeting soul.md constraints with ALIGNED/DRIFT/VIOLATION verdicts |
+
+**LayerLens Skill for OpenClaw:**

+# CI/CD Samples
+
+AI quality assurance must be integrated into your development workflow to catch regressions
+before they reach production. These samples provide ready-to-use components for embedding
+LayerLens evaluations into continuous integration pipelines: a GitHub Actions quality gate
+that blocks pull requests when AI output quality drops below threshold, a reusable gate
+script for any CI system, and a pre-commit hook for local development.
+
+## Prerequisites
+
+```bash
+pip install layerlens --index-url https://sdk.layerlens.ai/package
+```
+
+- A valid `LAYERLENS_STRATIX_API_KEY` set as an environment variable (locally or as a CI secret)
+- For the GitHub Actions workflow: repository write access to add workflow files
+- For the pre-commit hook: a local Git repository
+
+## Quick Start
+
+Run the quality gate script locally to verify your current evaluation pass rate:
+
+```bash
+export LAYERLENS_STRATIX_API_KEY=your-api-key
+python quality_gate.py --threshold 0.85
+```
+
+Expected output: the script evaluates recent traces against all configured judges, prints the
+aggregate pass rate, and exits with code 0 (pass) or 1 (fail) based on the threshold.
+
+## Samples
+
+| File | Scenario | Description |
+|------|----------|-------------|
+| `quality_gate.py` | CI/CD engineers adding AI quality checks to any pipeline | Evaluates recent traces against all judges and exits non-zero if the pass rate falls below a configurable threshold. Designed to be called from any CI system. |
+| `github_actions_gate.yml` | Teams using GitHub Actions for pull request validation | A complete GitHub Actions workflow that runs the quality gate on every pull request. Copy to `.github/workflows/ai-quality-gate.yml` in your repository. |
+| `pre_commit_hook.py` | Developers catching issues before committing | A Git pre-commit hook that runs a quick safety evaluation on staged changes. Prevents commits that introduce safety regressions. |
+
+## Installation
+
+### GitHub Actions
+
+```bash
+cp samples/cicd/github_actions_gate.yml .github/workflows/ai-quality-gate.yml
+```
+
+Add `LAYERLENS_STRATIX_API_KEY` as a repository secret in your GitHub settings.
+
+### Pre-Commit Hook
+
+```bash
+ln -sf "$(pwd)/samples/cicd/pre_commit_hook.py" .git/hooks/pre-commit
+chmod +x .git/hooks/pre-commit
+```
+
+## Expected Behavior
+
+The quality gate script outputs a pass/fail summary with per-judge breakdown. In CI, a
+failing gate will cause the pipeline step to exit non-zero, blocking the merge. The
+pre-commit hook runs silently on success and prints a warning message on failure.

+# Claude Code Skills
+
+These Markdown files define Claude Code slash-command skills that expose LayerLens SDK
+operations directly within the Claude Code CLI. Instead of writing Python scripts, developers
+can invoke LayerLens capabilities through natural language commands like `/trace`, `/evaluate`,
+or `/investigate` -- enabling AI-assisted quality assurance without leaving the terminal.
+
+## Prerequisites
+
+- Claude Code CLI installed and configured
+- The LayerLens Python SDK installed: `pip install layerlens --index-url https://sdk.layerlens.ai/package`
+- `LAYERLENS_STRATIX_API_KEY` set as an environment variable
+
+To register the skills, add the `samples/claude-code/skills/` directory to your Claude Code
+skill search path, or copy individual `.md` files into your project's `.claude/skills/`
+directory.
+
+## Quick Start
+
+After registering the skills, invoke the trace skill from Claude Code:
+
+```
+/trace
+```
+
+Claude Code will guide you through creating and uploading a trace interactively.
+
+## Skills
+
+| File | Command | Scenario | Description |
+|------|---------|----------|-------------|
+| `skills/trace.md` | `/trace` | Developers instrumenting LLM calls | Create, upload, and manage trace records. Guides the user through trace creation with prompts for model, input, and output data. |
+| `skills/evaluate.md` | `/evaluate` | QA teams running evaluations | Run evaluations against traces using specified judges. Supports selecting judges, setting thresholds, and reviewing results interactively. |
+| `skills/judge.md` | `/judge` | Platform teams managing evaluation criteria | Create, list, update, and delete judges. Provides an interactive workflow for defining judge criteria and testing them against sample traces. |
+| `skills/investigate.md` | `/investigate` | On-call engineers debugging production issues | Analyze traces for errors, latency anomalies, and cost outliers. Produces a structured investigation report with suggested remediation steps. |
+| `skills/benchmark.md` | `/benchmark` | ML teams comparing model performance | Run benchmarks across models and review comparative results. Supports custom task batteries and historical trend analysis. |
+| `skills/optimize.md` | `/optimize` | Teams refining judge accuracy | Optimize judge configurations by testing against labeled datasets and adjusting scoring parameters to improve precision and recall. |
+
+## Expected Behavior
+
+Each skill operates interactively within the Claude Code session. The skill prompts the user
+for required inputs, executes the corresponding LayerLens SDK operations, and presents
+formatted results directly in the terminal. All operations use the authenticated Stratix
+client and persist data to your LayerLens workspace.

+    api_key="sk-...",
+)
+
+# Browse the public catalog
+public_models = client.public.models.get()
+```
+
+## SDK Reference: Benchmarks
+
+```python

+    search="query text",          # optional
+)
+```
+
+## Instructions
+
+When the user asks to work with models, benchmarks, or comparisons:
+
+### Browsing and adding models/benchmarks
+1. Use `client.public.models.get()` or `client.public.benchmarks.get()` to browse the full catalog.
+2. Use `client.models.get()` or `client.benchmarks.get()` to see what is already in the project.
+3. Use `.add()` to add catalog items to the project and `.remove()` to remove them.
+
+### Creating custom benchmarks
+1. For a dataset-based benchmark: prepare a JSONL file and use `client.benchmarks.create_custom()`.
+2. For an AI-generated benchmark: use `client.benchmarks.create_smart()` with a system prompt and optional reference files.
+3. Sample dataset files are in `samples/data/datasets/` and `samples/data/industry/`.
+
+### Comparing evaluations or models
+1. To compare two evaluation runs: use `client.public.comparisons.compare()` with both evaluation IDs.
+2. To compare two models on the same benchmark: use `client.public.comparisons.compare_models()`.
+3. Use `outcome_filter="disagree"` to focus on cases where the two differ.
+
+See `samples/core/model_benchmark_management.py` for model/benchmark CRUD, `samples/core/run_evaluation.py` for running evaluations, and `samples/core/compare_evaluations.py` for comparisons.

+# Returns ResultsResponse with .results list
+```
+
+## Instructions
+
+When the user asks to evaluate:
+
+### Trace Evaluation (judge a specific trace)
+1. Ensure the user has a trace ID and a judge ID. If not, help them find or create these first.
+2. Optionally estimate cost with `client.trace_evaluations.estimate_cost()`.
+3. Run `client.trace_evaluations.create(trace_id=..., judge_id=...)`.
+4. Wait briefly, then fetch results with `client.trace_evaluations.get_results(id)`.
+5. Display the score and outcome for each result.
+
+### Model Evaluation (model vs benchmark)
+1. Help the user select a model and benchmark using `client.models.get()` and `client.benchmarks.get()`, or look up by key.
+2. Create the evaluation with `client.evaluations.create(model=model, benchmark=benchmark)`.
+3. Wait for completion with `client.evaluations.wait_for_completion()`.
+4. Fetch and display results with `client.results.get(evaluation=evaluation)`.
+
+See `samples/core/trace_evaluation.py` for the trace evaluation workflow and `samples/core/run_evaluation.py` for the model evaluation workflow.

+
+## SDK Reference

+from layerlens import Stratix
+client = Stratix()
+
+# Step 1: List recent traces
+response = client.traces.get_many(
+    page_size=50,              # fetch a good sample

+# Step 5: List evaluations for a trace to see past judgments
+evals = client.trace_evaluations.get_many(
+    trace_id="trace_id",
+    sort_by="created_at",
+    sort_order="desc",
+)
+```
+
+## Investigation Workflow
+
+When the user asks to investigate traces, follow this structured approach:
+
+### 1. Scope the investigation
+- Ask what they are looking for: errors, slow responses, quality issues, or a specific problem.
+- Use `client.traces.get_sources()` to see available data sources if needed.
+
+### 2. Fetch and filter traces
+- Use `client.traces.get_many()` with appropriate filters:
+  - `status="error"` for error traces
+  - `search="keyword"` for text search across trace content
+  - `sort_by="created_at"` and `sort_order="desc"` for most recent
+- Display a summary: total count, count matching filters, and a preview of the first few traces.
+
+### 3. Inspect suspicious traces
+- Use `client.traces.get(id)` to pull full trace details.
+- Examine the trace data dict for:
+  - `input` -- what was sent to the model
+  - `output` -- what the model returned
+  - `metadata` -- model name, latency, tokens, error codes
+  - `error` -- error messages if present
+- Look for patterns: repeated errors, high latency in metadata, empty outputs.
+
+### 4. Evaluate traces with a judge (optional)
+- If the user wants automated quality assessment, create or select a judge.
+- Estimate cost first with `estimate_cost()`.
+- Run `trace_evaluations.create()` on the suspicious traces.
+- Fetch and display results showing scores and outcomes.
+
+### 5. Summarize findings
+- Report: total traces examined, issues found, patterns identified.
+- Recommend next steps (fix prompts, adjust model, escalate errors).
+
+See `samples/core/trace_investigation.py` for a complete investigation workflow example.

+You are helping the user manage judges in the LayerLens platform using the Python SDK. Judges are LLM-powered evaluators that score traces against a defined evaluation goal.
+
+## SDK Reference
+
+```python
+from layerlens import Stratix

+
+# List available models to use as the judge's backing LLM
+models = client.models.get(type="public")
+# Each model has .id, .name, .key

+    evaluation_goal="Evaluate AI responses for accuracy, completeness, and safety.",  # what the judge checks
+    model_id="model_id_here",           # backing LLM model ID
+)
+# Returns Judge with .id, .name, .version
+

+)
+# Returns updated Judge
+
+# Delete a judge
+deleted = client.judges.delete("judge_id_here")
+# Returns deleted Judge with .id
+```
+
+## Instructions
+
+When the user asks to work with judges:
+1. If they want to create a judge: first fetch available models with `client.models.get(type="public")` so they can pick a backing LLM. Then call `client.judges.create()` with name, evaluation_goal, and model_id. The `evaluation_goal` is a natural language description of what the judge should evaluate.
+2. If they want to list judges: use `client.judges.get_many()` and display name, ID, version, and run count.
+3. If they want to inspect a judge: use `client.judges.get(id)` and show all fields.
+4. If they want to update: use `client.judges.update(id, ...)` with only the fields to change.
+5. If they want to delete: confirm the judge ID with the user before calling `client.judges.delete(id)`.
+
+When crafting the `evaluation_goal`, help the user write a clear, specific description of what the judge should evaluate (e.g., factual accuracy, safety compliance, tone, completeness).
+
+See `samples/core/create_judge.py` for a full CRUD example and `samples/core/judge_creation_and_test.py` for creating and testing a judge end-to-end.

+response = client.judge_optimizations.get_many(judge_id="judge_id_here")
+# Returns JudgeOptimizationsResponse with .optimization_runs list, .count
+
+# Step 5: Apply the optimized version to the judge
+applied = client.judge_optimizations.apply("optimization_run_id")
+# Updates the judge with the optimized evaluation criteria
+```
+
+## Instructions
+
+When the user asks to optimize a judge:
+
+1. **Identify the judge**: Get the judge ID. If the user does not have one, list judges with `client.judges.get_many()` and help them pick one. The judge should have completed trace evaluations for optimization to work well.
+
+2. **Choose a budget**: Ask the user to pick a budget level:
+   - `"low"` -- faster, cheaper, smaller improvement
+   - `"medium"` -- balanced (recommended default)
+   - `"high"` -- most thorough, higher cost, best results
+
+3. **Estimate cost**: Run `client.judge_optimizations.estimate(judge_id=..., budget=...)` and show the estimate to the user before proceeding.
+
+4. **Create the run**: After user confirmation, run `client.judge_optimizations.create(judge_id=..., budget=...)`.
+
+5. **Poll for completion**: Check status periodically with `client.judge_optimizations.get(run_id)`. A typical optimization takes a few minutes. Poll every 10 seconds.
+
+6. **Apply results**: Once status is `"completed"`, ask the user if they want to apply the optimization with `client.judge_optimizations.apply(run_id)`. This updates the judge with the improved evaluation criteria.
+
+Always estimate cost and get user confirmation before creating the optimization run.
+
+See `samples/core/judge_optimization.py` for a complete optimization workflow.

+description: Upload, list, inspect, and manage traces in LayerLens
+user_invocable: true
+---
+
+You are helping the user manage traces in the LayerLens platform using the Python SDK.
+
+## SDK Reference
+
+```python
+from layerlens import Stratix
+client = Stratix()
+
+# Upload traces from a JSONL/JSON file (max 50 MB)
+result = client.traces.upload("path/to/traces.jsonl")
+# Returns CreateTracesResponse with .trace_ids list
+
+# List traces with filtering and pagination
+response = client.traces.get_many(
+    page_size=20,           # default 100, max 500
+    sort_by="created_at",   # sort field
+    sort_order="desc",      # asc or desc
+    source="filename.jsonl", # filter by source file
+    status="error",         # filter by status
+    search="query text",    # text search
+)
+# Returns TracesResponse with .traces list, .count, .total_count
+
+# Get a single trace by ID
+trace = client.traces.get("trace_id_here")
+# Returns Trace with .id, .data, .filename, .created_at
+
+# Delete a trace
+deleted = client.traces.delete("trace_id_here")  # Returns bool
+
+# Get available trace sources
+sources = client.traces.get_sources()  # Returns List[str]
+```
+
+## Instructions
+
+When the user asks to work with traces:
+1. If they want to upload: use `client.traces.upload(file_path)`. The file must be JSON or JSONL format, max 50 MB.
+2. If they want to list/search: use `client.traces.get_many()` with appropriate filters. Display trace IDs, creation dates, and sources.
+3. If they want to inspect: use `client.traces.get(id)` and display the trace data including input, output, and metadata.
+4. If they want to delete: confirm the trace ID with the user before calling `client.traces.delete(id)`.
+5. If they want to see what sources exist: use `client.traces.get_sources()`.
+
+Always show the trace IDs returned from uploads so the user can reference them later.
+
+Sample trace data files are available in `samples/data/traces/` (simple_llm_trace.json, rag_pipeline_trace.json, multi_agent_trace.json, error_trace.json, batch_traces.jsonl).
+
+See `samples/core/basic_trace.py` for a full upload example and `samples/core/trace_investigation.py` for an investigation workflow.

+# CopilotKit Samples
+
+Building AI-powered user interfaces requires more than backend evaluation logic -- it requires
+real-time feedback loops between the AI backend and the frontend. These samples provide
+CopilotKit CoAgents (LangGraph-based) and React components that connect LayerLens evaluation
+capabilities to interactive UIs, enabling human-in-the-loop evaluation workflows where users
+can review, confirm, and act on AI quality assessments in real time.
+
+## Prerequisites
+
+```bash
+pip install layerlens --index-url https://sdk.layerlens.ai/package copilotkit langgraph pydantic mcp
+npm install @copilotkit/react-core  # for frontend components
+export LAYERLENS_STRATIX_API_KEY=your-api-key
+```
+
+## Quick Start
+
+Start with the Evaluator Agent to see the core human-in-the-loop pattern:
+
+```bash
+python agents/evaluator_agent.py
+```
+
+Expected output: the agent parses an evaluation intent, selects appropriate judges, pauses
+for human confirmation, executes the evaluation, and emits AG-UI protocol events at each step.
+
+## Agents (LangGraph CoAgents)
+
+| File | Scenario | Description |
+|------|----------|-------------|
+| `agents/evaluator_agent.py` | Product teams building evaluation dashboards | A multi-step evaluation workflow: parses user intent, selects judges, requests human confirmation before execution, runs evaluations, and summarizes results. Emits AG-UI events for real-time frontend rendering. |
+| `agents/investigator_agent.py` | Operations teams building trace debugging UIs | Fetches a trace by ID, analyzes spans for errors, latency anomalies, and cost outliers, then generates actionable fix suggestions. Designed for integration into incident investigation dashboards. |
+
+## React Components
+
+| File | Description |
+|------|-------------|
+| `components/EvaluationCard.tsx` | Renders evaluation results with score breakdowns and judge verdicts. |
+| `components/TraceCard.tsx` | Displays trace metadata, span hierarchy, and timing information. |
+| `components/JudgeVerdictCard.tsx` | Shows individual judge verdicts with pass/fail indicators. |
+| `components/MetricCard.tsx` | Renders a single metric with trend visualization. |
+| `components/ComplianceCard.tsx` | Displays compliance status with regulation-specific details. |
+| `components/index.ts` | Barrel export for all components. |
+
+## React Hooks
+
+| File | Description |
+|------|-------------|
+| `hooks/useLayerLensActions.ts` | CopilotKit action hooks for triggering evaluations and investigations. |
+| `hooks/useLayerLensContext.ts` | Context hook for sharing LayerLens state across components. |
+| `hooks/index.ts` | Barrel export for all hooks. |
+
+## Architecture
+
+```
+CopilotKit Frontend (React)
+    |
+    v
+CoAgent (LangGraph StateGraph)
+    |
+    v
+LayerLens Python SDK (Stratix client)
+    |
+    v
+LayerLens API
+```
+
+The agents emit AG-UI protocol events that CopilotKit renders as progress cards, confirmation
+dialogs, and result summaries in the frontend. The React components and hooks are provided as
+reference implementations for building your own LayerLens-powered UI.

+# Core Samples
+
+These samples cover the foundational operations of the LayerLens Python SDK. They address the
+core problem every AI team faces: how to systematically trace, evaluate, and improve LLM
+interactions across your application. Start here to build familiarity with the SDK before
+exploring domain-specific or advanced patterns.
+
+## Prerequisites
+
+```bash
+pip install layerlens --index-url https://sdk.layerlens.ai/package
+export LAYERLENS_STRATIX_API_KEY=your-api-key
+```
+
+## Quick Start
+
+Run `quickstart.py` for a minimal end-to-end walkthrough that creates a trace, defines a judge,
+and runs an evaluation in under 30 lines of code:
+
+```bash
+python quickstart.py
+```
+
+Expected output: a trace ID, judge ID, and evaluation summary printed to the console.
+
+## Samples
+
+| File | Scenario | Description |
+|------|----------|-------------|
+| `quickstart.py` | First-time setup | Minimal end-to-end example covering trace creation, judge setup, and evaluation in a single script. |
+| `basic_trace.py` | Observability engineers instrumenting LLM calls | Create, retrieve, and manage trace records for individual LLM interactions. |
+| `run_evaluation.py` | QA leads running scheduled quality checks | Execute a full evaluation lifecycle: configure judges, submit traces, and collect scored results. |
+| `create_judge.py` | Platform teams defining quality standards | CRUD operations for judge resources -- create, read, update, and delete evaluation judges. |
+| `trace_evaluation.py` | Developers validating prompt changes | Evaluate traced LLM interactions against one or more judges to detect regressions. |
+| `benchmark_evaluation.py` | ML teams comparing model performance | Run a model against a benchmark, wait for completion, retrieve and analyze scored results. |
+| `judge_optimization.py` | ML engineers tuning evaluation criteria | Programmatically refine judge configurations to improve scoring precision and recall. |
+| `compare_evaluations.py` | Teams comparing prompt or model variants | Compare scored results across multiple evaluation runs to identify the best-performing configuration. |
+| `async_workflow.py` | High-throughput pipelines | Asynchronous SDK usage for non-blocking trace uploads and evaluation submissions. |
+| `model_benchmark_management.py` | Platform teams cataloging models | Register models and benchmarks, then query benchmark results for reporting. |
+| `integration_management.py` | Teams managing LayerLens integrations | List, inspect, and test configured integrations using the `client.integrations` API. |
+| `custom_model.py` | Teams using private or fine-tuned models | Register and manage custom model definitions within the LayerLens model catalog. |
+| `custom_benchmark.py` | Teams defining proprietary test suites | Create and run custom benchmarks tailored to your application's specific quality criteria. |
+| `trace_investigation.py` | On-call engineers debugging production issues | Investigate traces for errors, high latency, and anomalous token usage patterns. |
+| `evaluation_pipeline.py` | CI/CD and batch workflows | Orchestrate a multi-step evaluation pipeline combining judges, traces, and result aggregation. |
+| `evaluation_filtering.py` | Analysts querying evaluation history | Filter and paginate evaluation results by status, date range, judge, or score threshold. |
+| `paginated_results.py` | Large-scale data retrieval | Demonstrate cursor-based pagination for traces, evaluations, and judge listings. |
+| `public_catalog.py` | Teams exploring built-in judges | Browse and query the public judge and model catalog provided by LayerLens. |
+| `judge_creation_and_test.py` | Compliance teams building PII detectors | Create a custom PII judge, run it against sample traces, and verify detection accuracy. |
+| `async_results.py` | Polling for long-running evaluations | Submit evaluations asynchronously and poll for completion with timeout handling. |
+
+## Expected Behavior
+
+Each sample prints its results to stdout. Trace and evaluation IDs are generated server-side
+and will differ between runs. Samples that create resources (judges, evaluations) will persist
+those resources in your LayerLens workspace unless explicitly deleted.

+Async Patterns -- LayerLens Python SDK Sample
+=============================================
+
+Demonstrates async SDK usage with ``AsyncStratix``:
+
+  1. **Concurrent result fetching** -- fetch results for multiple
+     evaluations in parallel using ``asyncio.gather``.
+  2. **Concurrent evaluation creation** -- create and run multiple
+     evaluations in parallel with progress tracking.
+  3. **Judge + trace combined workflow** -- create a judge, upload
+     traces, run trace evaluations concurrently, and collect results.
+
+Prerequisites
+-------------
+* ``pip install layerlens --index-url https://sdk.layerlens.ai/package``
+* Set ``LAYERLENS_STRATIX_API_KEY`` environment variable
+* At least one model and benchmark configured in the project

+
+  1. Upload traces from a JSONL file.
+  2. List traces with filtering and pagination.
+  3. Get a single trace by ID.
+  4. Get available trace sources.
+  5. Delete a trace.
+
+This sample ports the ateam core/basic_trace.py sample to use the
+layerlens SDK client instead of raw httpx calls.

+Benchmark Evaluation -- LayerLens Python SDK Sample
+====================================================
+
+Demonstrates the model+benchmark evaluation workflow:
+
+  1. Fetch available models and benchmarks.
+  2. Create an evaluation that scores a model against a benchmark.
+  3. Poll for completion with configurable timeout.
+  4. Retrieve and display paginated results.
+
+This is the standard evaluation path for comparing model performance
+on public or custom benchmarks. For trace-level evaluation (scoring
+individual LLM interactions with judges), see ``trace_evaluation.py``.
+
+Prerequisites
+-------------
+* ``pip install layerlens --index-url https://sdk.layerlens.ai/package``
+* Set ``LAYERLENS_STRATIX_API_KEY`` environment variable
+* At least one model and one benchmark must be available in your project
+  or the public catalog.

+Judge Creation and Testing -- LayerLens Python SDK Sample
+=========================================================

+Paginated Results -- LayerLens Python SDK Sample
+================================================
+
+Demonstrates two approaches for fetching evaluation results:
+
+  1. **Manual pagination** -- iterate page-by-page using
+     ``client.results.get(evaluation=, page=, page_size=)``
+     with full control over each request.
+
+  2. **Automatic pagination** -- fetch all results at once using
+     ``client.results.get_all(evaluation=)`` which handles
+     pagination internally.
+
+Prerequisites

+* Set ``LAYERLENS_STRATIX_API_KEY`` environment variable
+* At least one completed evaluation in the project

+Public Catalog -- LayerLens Python SDK Sample
+=============================================
+
+Demonstrates the public (unauthenticated) catalog APIs:

+Trace Evaluation -- LayerLens Python SDK Sample
+================================================
+
+Demonstrates the trace evaluation workflow using the SDK:
+
+  1. Upload traces from a JSONL file.
+  2. Create a judge.
+  3. Estimate the cost of evaluating traces with the judge.
+  4. Run a trace evaluation (judge against trace).
+  5. Poll for results.
+  6. Fetch and display evaluation results.
+  7. Clean up (delete judge and traces).
+
+This combines concepts from the ateam core/run_evaluation.py and
+core/create_judge.py samples, adapted for the SDK's trace evaluation
+resource.
+
+Prerequisites
+-------------
+* ``pip install layerlens --index-url https://sdk.layerlens.ai/package``
+* Set ``LAYERLENS_STRATIX_API_KEY`` environment variable
+

+-----
+::

+# Multi-Agent Evaluation Samples (Cowork Patterns)
+
+When multiple AI agents collaborate on a task -- whether through
+[Claude Cowork](https://claude.com/product/cowork) sub-agent orchestration,
+[Claude Code Agent Teams](https://code.claude.com/docs/en/agent-teams),
+or any multi-agent framework -- each agent's contribution needs independent
+quality assessment. A generator agent might produce fluent but factually wrong text.
+A code reviewer might miss a security vulnerability. A RAG retriever might surface
+irrelevant documents.
+
+These samples demonstrate multi-agent evaluation patterns where LayerLens judges
+score each agent's output independently, and evaluation results drive the coordination
+between agents. The patterns apply to any multi-agent architecture:
+
+- **Claude Cowork**: sub-agents working on parallel workstreams with shared files
+- **Claude Code Agent Teams**: coordinated Claude Code sessions with a team lead
+- **LangGraph / CrewAI / AutoGen**: any framework-based multi-agent system
+- **Custom pipelines**: hand-rolled agent orchestration in your own code
+
+## Prerequisites
+
+```bash
+pip install layerlens --index-url https://sdk.layerlens.ai/package
+export LAYERLENS_STRATIX_API_KEY=your-api-key
+```
+
+## Quick Start
+
+Start with `multi_agent_eval.py` for the simplest two-agent pattern:
+
+```bash
+python multi_agent_eval.py
+```
+
+Expected output: a Generator agent produces a response, an Evaluator agent scores it
+using safety and factual accuracy judges via the LayerLens SDK, and the combined results
+are printed with per-judge verdicts.
+
+## Samples
+
+| File | Pattern | Description |
+|------|---------|-------------|
+| `multi_agent_eval.py` | **Generator-Evaluator** | One agent produces responses, a second agent scores them with safety and factual accuracy judges. The foundational pattern for any multi-agent evaluation workflow. |
+| `code_review.py` | **Instrumentor-Reviewer** | One agent uploads code traces, a reviewer agent evaluates them with code execution, security, and metrics judges. Applicable to AI-assisted code generation in Cowork or Agent Teams. |
+| `pair_programming.py` | **Rubric Writer-Tester** | One agent creates a judge, the other tests it against traces, and they iteratively refine the judge via `judges.update()`. Demonstrates collaborative judge development. |
+| `rag_assessment.py` | **RAG Runner-Quality Judge** | One agent executes retrieval queries, the other evaluates groundedness and retrieval quality. Useful for monitoring RAG accuracy in any pipeline. |
+| `incident_response.py` | **Detector-Responder** | A Detector agent evaluates recent traces for safety violations and a Responder agent triages flagged traces with additional targeted judges. Models automated incident triage. |
+
+## Expected Behavior
+
+Each sample simulates a multi-agent interaction and prints evaluation results from each
+stage. Agent roles, trace IDs, and judge verdicts are clearly labeled in the output. No
+external agent framework is required -- all coordination is implemented directly in each
+script using the LayerLens SDK. In production, the shared state dict would be replaced
+by your agent framework's coordination mechanism (Cowork shared files, Agent Teams
+messaging, LangGraph state, etc.).

+# Sample Data
+
+The SDK samples reference pre-built trace files, evaluation datasets, and industry-specific
+test data. This directory provides all the data needed to run the samples without connecting
+to a live AI provider. Use these files to test SDK operations locally, seed your LayerLens
+workspace with representative data, or build automated test suites for your evaluation pipelines.
+
+## Prerequisites
+
+No additional dependencies are required. The data files are consumed by samples in other
+directories via relative path references.
+
+## Quick Start
+
+Upload a trace file to your LayerLens workspace:
+
+```bash
+export LAYERLENS_STRATIX_API_KEY=your-api-key
+python -c "from layerlens import Stratix; Stratix().traces.upload('samples/data/traces/simple_llm_trace.json')"
+```
+
+Expected output: the trace ID of the newly uploaded trace record.
+
+## Traces
+
+| File | Description |
+|------|-------------|
+| `traces/simple_llm_trace.json` | A single LLM call trace (OpenAI support assistant) with prompt, completion, and token usage. The simplest trace format for getting started. |

+| `datasets/generic_qa.jsonl` | A larger QA dataset spanning factual, reasoning, analytical, and creative categories. Suitable for benchmark runs and model comparison. |
+
+## Industry Data
+
+Domain-specific evaluation datasets with expected outcomes for judge testing. Each file is
+referenced by the corresponding sample in `samples/industry/`.

While supporters claim it connects people, the reality is that platforms like Instagram and TikTok damage mental health, reduce face-to-face social skills, and create addictive behaviors that interfere with academic performance.\n\nFirst, studies from the American Psychological Association show that teens who spend more than three hours daily on social media have double the risk of anxiety and depression. The constant comparison to curated, filtered images creates unrealistic standards. My own classmate admitted she deleted photos that didn't get enough likes, showing how deeply these platforms affect self-worth.\n\nSecond, social media replaces meaningful human interaction with shallow digital exchanges. When teens sit together at lunch scrolling their phones instead of talking, they miss opportunities to develop empathy and conversational skills they will need throughout their lives. A 2025 Stanford study found that teens who limited social media use reported feeling closer to their friends within just two weeks.\n\nFinally, the addictive design of these platforms steals time from homework, sleep, and physical activity. Notifications, infinite scrolling, and algorithmic content feeds are engineered to keep users engaged as long as possible. The average American teen spends over four hours per day on social media, time that could be spent on activities that genuinely build skills and well-being.\n\nIn conclusion, while social media offers some benefits for staying connected, its negative effects on mental health, real-world relationships, and productive time use far outweigh the positives. Schools should educate students about these risks and parents should set reasonable limits on usage.", "rubric_criteria": ["thesis_clarity", "evidence_and_support", "organization", "voice_and_tone", "conventions"], "expected_scores": {"thesis_clarity": 4, "evidence_and_support": 5, "organization": 4, "voice_and_tone": 4, "conventions": 5}, "expected_feedback": "Strong persuasive essay with a clear thesis and well-organized arguments.

+{"id": "edu-002", "grade_level": 10, "subject": "US History", "prompt": "Analyze the causes and consequences of the Great Migration (1916-1970) on American society.", "essay_text": "The Great Migration was one of the most significant demographic shifts in American history. Between 1916 and 1970, approximately six million African Americans moved from the rural South to cities in the North, Midwest, and West. This massive relocation reshaped the cultural, political, and economic landscape of the entire nation.\n\nThe causes of the Great Migration were both push and pull factors. In the South, African Americans faced Jim Crow laws that enforced racial segregation, limited voting rights, and denied economic opportunities. The boll weevil infestation devastated cotton crops in the 1910s, destroying the agricultural economy that many Black families depended on. Racial violence, including lynchings, created an atmosphere of constant fear. Meanwhile, northern cities offered industrial jobs, especially during World War I when European immigration slowed and factories needed workers desperately.\n\nThe consequences were far reaching. Cities like Chicago, Detroit, and New York saw their Black populations explode, creating vibrant cultural centers. The Harlem Renaissance emerged directly from this concentration of African American artists, writers, and musicians in New York City. Jazz, blues, and gospel music spread across the country, fundamentally changing American culture.\n\nPolitically, the migration shifted power. As African Americans gained voting rights in northern states, they became an important voting bloc. This political influence would eventually contribute to the Civil Rights Movement of the 1950s and 1960s. However, migrants also faced discrimination in the North through housing covenants, redlining, and de facto segregation that created lasting patterns of urban inequality.\n\nThe Great Migration demonstrates how the movement of people can transform an entire nation, and its effects on housing patterns, cultural development, and political alignment are still visible in America today.", "rubric_criteria": ["thesis_clarity", "historical_accuracy", "analysis_depth", "use_of_evidence", "conventions"], "expected_scores": {"thesis_clarity": 4, "historical_accuracy": 5, "analysis_depth": 4, "use_of_evidence": 4, "conventions": 4}, "expected_feedback": "Well-researched essay demonstrating strong historical knowledge.

+{"id": "edu-003", "grade_level": 6, "subject": "Science", "prompt": "Explain the water cycle and why it is important for life on Earth.", "essay_text": "The water cycle is how water moves around on Earth. It goes from the oceans and lakes up into the sky and then back down again. This cycle is really important because all living things need water to survive.\n\nThe water cycle starts with evaporation. The sun heats up water in oceans, lakes, and rivers, and the water turns into water vapor which is like an invisible gas. Plants also release water vapor through their leaves, which is called transpiration. All this water vapor rises up into the atmosphere.\n\nWhen the water vapor gets high enough, it cools down and turns back into tiny water droplets. This is called condensation, and it's what makes clouds. The droplets stick together around tiny pieces of dust or pollen in the air. When enough droplets collect together, the cloud gets heavy.\n\nThen comes precipitation which is when the water falls back down as rain, snow, sleet, or hail. Some of this water flows into rivers and streams as runoff and goes back to the ocean. Some of it soaks into the ground and becomes groundwater that plants can use with their roots.\n\nThe water cycle is important because it cleans and recycles water. When water evaporates it leaves behind salt and pollutants so the rain that falls is fresh water. Without the water cycle, all our fresh water would eventually flow to the ocean and become salty. Plants, animals, and people all depend on the water cycle to keep providing fresh water.\n\nIn conclusion the water cycle is a continuous process that keeps water moving and available for all living things on our planet.", "rubric_criteria": ["thesis_clarity", "scientific_accuracy", "organization", "vocabulary_usage", "conventions"], "expected_scores": {"thesis_clarity": 3, "scientific_accuracy": 4, "organization": 4, "vocabulary_usage": 3, "conventions": 3}, "expected_feedback": "Good explanation of the water cycle stages with accurate scientific content.

+{"id": "edu-004", "grade_level": 11, "subject": "English Language Arts", "prompt": "Compare and contrast the portrayal of ambition in Shakespeare's Macbeth and F. Scott Fitzgerald's The Great Gatsby.", "essay_text": "Ambition is a driving force that can elevate or destroy, and both Shakespeare's Macbeth and Fitzgerald's The Great Gatsby explore its dual nature through protagonists whose desires ultimately consume them. While separated by centuries and vastly different settings, both works arrive at a similar conclusion: unchecked ambition, detached from moral grounding, leads to self-destruction.\n\nMacbeth's ambition is ignited by supernatural prophecy and fanned by Lady Macbeth's manipulation. His desire for the Scottish crown transforms him from a loyal thane into a murderer. Shakespeare uses the metaphor of blood—\"Will all great Neptune's ocean wash this blood clean from my hand?\"—to show how each act of violence stains Macbeth's conscience more deeply. His ambition is vertical, aimed at seizing power that already exists within a rigid hierarchy.\n\nGatsby's ambition, by contrast, is horizontal and self-invented. He constructs an entirely new identity, transforming James Gatz of North Dakota into the mysterious Jay Gatsby of West Egg. His ambition is rooted not in political power but in romantic idealism—the desire to recapture Daisy Buchanan and the version of himself she represents. Fitzgerald's green light at the end of Daisy's dock symbolizes an ambition directed at an illusion, something perpetually out of reach.\n\nBoth protagonists engage in moral compromise. Macbeth murders Duncan, Banquo, and Macduff's family. Gatsby accumulates wealth through bootlegging and association with organized crime. Yet their self-awareness differs markedly. Macbeth recognizes his moral decay, declaring life \"a tale told by an idiot, full of sound and fury, signifying nothing.\" Gatsby never achieves this recognition, dying still believing in his dream.\n\nThe most striking parallel is how both men are ultimately betrayed by the very things they pursued. Macbeth's crown brings paranoia rather than security. Gatsby's wealth cannot purchase Daisy's genuine love or entry into old-money society. Both authors suggest that ambition becomes destructive when it demands the impossible—for Macbeth, legitimacy through illegitimate means; for Gatsby, the recreation of a past moment.\n\nThese works endure because ambition remains a universal human experience. Together, they warn that greatness pursued without integrity becomes its own punishment.", "rubric_criteria": ["thesis_clarity", "textual_analysis", "comparative_structure", "use_of_evidence", "conventions"], "expected_scores": {"thesis_clarity": 5, "textual_analysis": 5, "comparative_structure": 5, "use_of_evidence": 5, "conventions": 5}, "expected_feedback": "Exceptional comparative essay with a sophisticated thesis and nuanced analysis.

+{"id": "edu-005", "grade_level": 7, "subject": "Mathematics", "prompt": "Write an essay explaining how ratios and proportions are used in real life. Give at least three examples.", "essay_text": "Ratios and proportions are math concepts that we use all the time without even realizing it. A ratio compares two numbers and a proportion is when two ratios are equal. These ideas show up in cooking, sports, shopping, and many other everyday situations.\n\nOne common example is cooking and baking. If a recipe for cookies makes 24 cookies and you want to make 48, you need to double all the ingredients. Thats using proportions. If the recipe says 2 cups of flour for 24 cookies, you know the ratio is 2:24 or 1:12, meaning one cup of flour for every twelve cookies. So for 48 cookies you need 4 cups.\n\nAnother example is in sports statistics. Baseball uses batting averages which are ratios of hits to at-bats. If a player gets 3 hits in 10 at-bats, their ratio is 3:10 or a .300 batting average. Coaches use these ratios to compare players and decide who should bat in important situations.\n\nA third example is shopping and comparing prices. If one store sells 6 apples for $3 and another sells 10 apples for $4.50, you can use ratios to figure out which is the better deal. The first store charges $0.50 per apple and the second charges $0.45 per apple, so the second store is cheaper.\n\nYou also see ratios in maps where 1 inch might equal 50 miles and in mixing paint colors where you might combine blue and yellow in a 2:1 ratio to get a specific shade of green.\n\nIn conclusion ratios and proportions help us make fair comparisons, scale things up or down, and make smart decisions in our daily lives.", "rubric_criteria": ["thesis_clarity", "mathematical_accuracy", "real_world_connections", "organization", "conventions"], "expected_scores": {"thesis_clarity": 3, "mathematical_accuracy": 4, "real_world_connections": 5, "organization": 4, "conventions": 3}, "expected_feedback": "Strong essay with excellent real-world examples that clearly demonstrate understanding of ratios and proportions.

+{"id": "edu-006", "grade_level": 9, "subject": "Biology", "prompt": "Describe the process of natural selection and explain how it leads to evolution over time.", "essay_text": "Natural selection is the mechanism by which evolution occurs, first described by Charles Darwin after his observations in the Galapagos Islands. It explains how species change over generations through the survival and reproduction of individuals best suited to their environment.\n\nThe process of natural selection requires four conditions. First, there must be variation within a population. Not all individuals are identical—some finches have larger beaks while others have smaller ones. Second, these variations must be heritable, meaning they can be passed from parents to offspring through genes. Third, there must be a struggle for existence because resources like food, water, and shelter are limited. Finally, there must be differential survival and reproduction, where individuals with advantageous traits are more likely to survive and pass those traits to the next generation.\n\nA clear example is the peppered moth in England during the Industrial Revolution. Before industrialization, light-colored moths were camouflaged against pale tree bark and survived better than dark moths. When pollution darkened the trees with soot, dark moths suddenly had the advantage and their numbers increased dramatically. This shift happened within decades, showing natural selection in action.\n\nOver thousands or millions of years, the accumulation of small changes through natural selection can lead to the development of entirely new species. This process, called speciation, often occurs when populations become geographically isolated and face different environmental pressures. The different finch species Darwin observed on separate Galapagos islands are a classic example of this.\n\nIt is important to note that natural selection does not have a goal or direction. It simply favors whatever traits happen to improve survival in the current environment. If the environment changes, previously advantageous traits may become disadvantageous. This is why biodiversity is important—it gives species the genetic variation needed to adapt to changing conditions.\n\nNatural selection is one of the most powerful ideas in science because it explains the incredible diversity of life on Earth through a simple, observable process.", "rubric_criteria": ["thesis_clarity", "scientific_accuracy", "use_of_evidence", "critical_thinking", "conventions"], "expected_scores": {"thesis_clarity": 4, "scientific_accuracy": 5, "use_of_evidence": 4, "critical_thinking": 4, "conventions": 5}, "expected_feedback": "Excellent essay demonstrating thorough understanding of natural selection. The four conditions are clearly articulated, and the peppered moth example is well-chosen. The paragraph addressing the non-directional nature of natural selection shows sophisticated thinking. Consider discussing genetic drift or other evolutionary mechanisms briefly to show awareness of the broader context."}
+{"id": "edu-007", "grade_level": 12, "subject": "Government", "prompt": "Evaluate whether the Electoral College should be abolished in favor of a national popular vote for presidential elections.", "essay_text": "The question of whether to abolish the Electoral College strikes at the heart of American democratic principles. While this institution has selected every president since 1789, its continued relevance in modern democracy deserves rigorous examination. Ultimately, the Electoral College should be reformed rather than abolished, as both systems carry significant trade-offs that a binary choice fails to address.\n\nProponents of abolition argue that the Electoral College violates the democratic principle of one person, one vote. A voter in Wyoming has roughly 3.6 times the electoral influence of a voter in California when measured by electoral votes per capita. Furthermore, five presidents have won office while losing the popular vote, most recently in 2016, undermining public confidence in democratic legitimacy. The winner-take-all system used by 48 states means that millions of Republican votes in California and Democratic votes in Texas are effectively meaningless, depressing turnout and distorting campaign strategy.\n\nHowever, defenders raise compelling counterpoints. The Electoral College forces candidates to build geographically diverse coalitions rather than concentrating solely on population centers. It preserves federalism by giving states a role in presidential selection, consistent with the Constitution's design of shared sovereignty. Small states and rural communities would lose virtually all political influence under a pure popular vote, potentially leading to policies that systematically neglect their needs.\n\nThe strongest argument for reform rather than abolition is practical. A constitutional amendment requires two-thirds of Congress and three-fourths of state legislatures, meaning small states that benefit from the current system hold an effective veto. The National Popular Vote Interstate Compact offers a creative workaround but faces legal challenges. Meanwhile, eliminating winner-take-all at the state level—as Maine and Nebraska already do—could address many concerns without requiring an amendment.\n\nThe debate also reveals deeper tensions about what kind of democracy America aspires to be. Pure majoritarianism can lead to tyranny of the majority, which the Founders explicitly feared. But excessive counter-majoritarian mechanisms can produce minority rule, which is equally dangerous to democratic legitimacy.\n\nA proportional allocation system within the existing Electoral College framework would preserve federalist principles while dramatically reducing the distortions that make the current system problematic. This pragmatic middle path better serves a diverse republic than either extreme.", "rubric_criteria": ["thesis_clarity", "argumentation_balance", "evidence_and_support", "critical_thinking", "conventions"], "expected_scores": {"thesis_clarity": 5, "argumentation_balance": 5, "evidence_and_support": 5, "critical_thinking": 5, "conventions": 5}, "expected_feedback": "Outstanding analytical essay that avoids the trap of a simplistic for-or-against position.

Everyone else had been swimming competitively for years, and on my first day of practice I finished dead last in every single drill. I wanted to quit before I even started.\n\nThe coach, Ms. Alvarez, must have noticed how discouraged I looked because she pulled me aside after practice. She told me that every swimmer on the team had been a beginner once, and that improvement comes from showing up consistently, not from natural talent. She suggested I come fifteen minutes early to work on my freestyle technique before the rest of the team arrived.\n\nFor the next six weeks I showed up early every single day. Ms. Alvarez broke down the freestyle stroke into parts—the catch, the pull, the recovery, the kick, and the breathing. We worked on one element at a time until it became automatic. Some days I felt like I was getting worse instead of better. My arms ached and I swallowed what felt like half the pool. There were mornings I sat in my mom's car in the parking lot trying to convince myself to go inside.\n\nBut slowly things began to click. By the fourth week my times had dropped by almost fifteen seconds in the 50-meter freestyle. Teammates who had ignored me started offering tips and encouragement. At our first meet in July I placed fifth out of eight swimmers in my heat—not a trophy performance but a genuine achievement for someone who could barely finish the distance a month earlier.\n\nWhat I learned from that summer goes beyond swimming. I learned that being bad at something is just the beginning, not the end. I learned that small daily improvements add up to big changes over time. And I learned that asking for help is not a sign of weakness but actually the smartest thing you can do when you are struggling.\n\nI still swim with the team. I am not the fastest, but I am no longer the slowest either, and I know that every lap is making me better.", "rubric_criteria": ["narrative_arc", "descriptive_detail", "reflection_depth", "voice_and_tone", "conventions"], "expected_scores": {"narrative_arc": 5, "descriptive_detail": 4, "reflection_depth": 4, "voice_and_tone": 5, "conventions": 4}, "expected_feedback": "Engaging personal narrative with a clear arc from challenge to growth.

+{"id": "edu-009", "grade_level": 10, "subject": "Chemistry", "prompt": "Explain the difference between ionic and covalent bonds, and describe how the type of bonding affects the properties of a substance.", "essay_text": "Chemical bonds are the forces that hold atoms together to form molecules and compounds. The two primary types of chemical bonds are ionic bonds and covalent bonds, and the type of bond in a substance determines many of its physical and chemical properties.\n\nIonic bonds form when one atom transfers electrons to another atom. This typically happens between metals and nonmetals. For example, in sodium chloride (table salt), sodium gives up one electron to chlorine. Sodium becomes a positively charged ion (Na+) and chlorine becomes a negatively charged ion (Cl-). The opposite charges attract each other strongly, creating a crystal lattice structure where each ion is surrounded by ions of the opposite charge.\n\nCovalent bonds form when atoms share electrons rather than transferring them. This usually occurs between two nonmetals. In a water molecule, oxygen shares electrons with two hydrogen atoms. Neither atom completely gives up its electrons, and the shared pairs hold the atoms together. Covalent bonds can be polar, where electrons are shared unequally, or nonpolar, where sharing is roughly equal.\n\nThe type of bonding profoundly affects a substance's properties. Ionic compounds like NaCl have high melting and boiling points because breaking the crystal lattice requires a lot of energy. They are typically solid at room temperature, dissolve in water, and conduct electricity when dissolved or melted because the free ions can carry charge. They are usually brittle because displacing ions in the lattice puts like charges next to each other, causing repulsion.\n\nCovalent compounds behave very differently. They generally have lower melting and boiling points because the forces between individual molecules are weaker than ionic bonds. Many are liquids or gases at room temperature. They usually do not conduct electricity because they lack free-moving charged particles. They are often soluble in nonpolar solvents rather than water.\n\nUnderstanding these differences in bonding helps chemists predict how substances will behave in reactions and what conditions are needed to work with them safely and effectively.", "rubric_criteria": ["thesis_clarity", "scientific_accuracy", "comparison_structure", "use_of_examples", "conventions"], "expected_scores": {"thesis_clarity": 4, "scientific_accuracy": 5, "comparison_structure": 5, "use_of_examples": 4, "conventions": 5}, "expected_feedback": "Clear and well-organized comparison of ionic and covalent bonds.

+{"id": "edu-010", "grade_level": 7, "subject": "Social Studies", "prompt": "Describe the geography of your state or region and explain how geographic features have influenced the economy and culture of the area.", "essay_text": "Colorado is a state with really diverse geography that has shaped everything about how people live and work here. From the towering Rocky Mountains in the west to the flat Great Plains in the east, the land itself has determined what industries thrive and what kind of culture has developed.\n\nThe Rocky Mountains are the most famous geographic feature of Colorado. They run through the middle of the state and include over fifty peaks above 14000 feet, called fourteeners. The mountains have driven Colorado's economy in different ways throughout history. In the 1800s gold and silver mining brought thousands of people to mountain towns like Leadville and Cripple Creek during the Pikes Peak Gold Rush. Today those same mountains drive a massive tourism and recreation industry. Skiing at resorts like Vail and Breckenridge brings in billions of dollars each year and hiking camping and climbing attract visitors from around the world.\n\nThe eastern part of Colorado is very different. The Great Plains stretch out flat and dry, and this geography made cattle ranching and wheat farming the dominant industries. The semi-arid climate means water has always been a critical issue. The South Platte and Arkansas Rivers provide irrigation water that makes agriculture possible, but fights over water rights have been part of Colorado politics for over a century.\n\nColorado's geography has also shaped its culture. The outdoor recreation lifestyle attracts people who value fitness, nature, and environmental conservation. Cities like Boulder and Fort Collins have strong cycling and running communities. The state's high elevation and sunny climate have made it a center for solar energy research and craft brewing, since the clean mountain water is excellent for making beer.\n\nIn conclusion Colorado shows how geography doesn't just provide scenery—it fundamentally shapes the economy, politics, and daily life of the people who live there.", "rubric_criteria": ["thesis_clarity", "geographic_knowledge", "analysis_depth", "organization", "conventions"], "expected_scores": {"thesis_clarity": 4, "geographic_knowledge": 4, "analysis_depth": 3, "organization": 4, "conventions": 3}, "expected_feedback": "Good essay connecting geographic features to economic and cultural outcomes. The contrast between mountain and plains regions is effective. Specific examples like fourteeners and Pikes Peak Gold Rush demonstrate solid knowledge. Conventions need attention: missing commas in lists and after introductory phrases, and the number 14000 should include a comma. Deepen the analysis by exploring how geography creates challenges, not just opportunities."}

If the employer acted independently, the private-search doctrine applies and the Fourth Amendment is not triggered. However, if law enforcement directed or encouraged the search, it becomes a government search requiring probable cause. The employee's expectation of privacy depends on the employer's monitoring policies and whether personal use was permitted or prohibited."}

Northwestern University", "citation": "595 U.S. 170", "year": 2022, "relevance": "Plan fiduciaries have duty to monitor and remove imprudent investment options regardless of participant choice"}], "expected_analysis": "Under Tibble's ongoing monitoring duty, an employer fiduciary must regularly evaluate the AI algorithm's performance and methodology, not merely its initial selection. If model drift caused underperformance and the fiduciary failed to detect or act on degrading performance, liability is likely under the prudent expert standard. The fiduciary must demonstrate it had processes in place to evaluate algorithmic investment strategies, including understanding of model risks."}

LinkedIn Corp.", "citation": "938 F.3d 985", "year": 2022, "relevance": "Scraping publicly available data does not constitute unauthorized access under CFAA even when it violates ToS"}], "expected_analysis": "After Van Buren narrowed the CFAA's scope, mere ToS violations likely do not constitute 'unauthorized access' or 'exceeding authorized access' under the statute. The key question is whether the AI agent bypassed technical access barriers. For publicly accessible websites, hiQ Labs suggests that automated access does not violate the CFAA. However, the deployer of the AI agent may face contractual liability for ToS breach and potential tortious interference claims."}

Growth is accelerated by EU AI Act enforcement (H2 2026), enterprise LLM production deployments, and the rising complexity of multi-agent architectures.\n\n## Our Position\nLayerLens Stratix is uniquely positioned with full-lifecycle AI governance -- the only platform combining observability, evaluation, policy enforcement, and compliance in a single solution. Our 13 framework adapters and Agent-as-a-Judge capability represent technical moats that competitors have not replicated.\n\n## Competitive Dynamics\nArize and Weights & Biases lead in brand recognition but focus on narrow ML monitoring. Datadog poses the primary bundling threat. Open-source alternatives (Langfuse) compete on price but lack enterprise governance features.\n\n## Recommended Actions\n1. **Compliance-first GTM** — Lead positioning around EU AI Act readiness (Q2 2026)\n2. **SDK expansion** — Ship Go and Java SDKs to unlock JVM-heavy enterprise accounts (Q3 2026)\n3. **SI channel** — Launch partner program for enterprise deployment scale (Q3 2026)\n\n## Key Metric Targets\n- Market share target: 4% by EOY 2026 (~$140M ARR)\n- Enterprise logo target: 50 net-new accounts\n- NRR target: 135%",

+# Industry Samples
+
+Regulated and domain-critical AI applications require evaluation criteria that go far beyond
+generic quality checks. A healthcare chatbot must be medically accurate. A trading assistant
+must comply with fiduciary obligations. A government service must be accessible and equitable.
+These samples demonstrate how to build industry-specific evaluation pipelines using judges
+tailored to the compliance, safety, and accuracy requirements of each vertical.
+
+## Prerequisites
+
+```bash
+pip install layerlens --index-url https://sdk.layerlens.ai/package
+export LAYERLENS_STRATIX_API_KEY=your-api-key
+```
+
+Industry samples reference domain-specific test data located in `samples/data/industry/`.
+
+## Quick Start
+
+Start with `financial_fraud.py` for a representative example of domain-specific evaluation:
+
+```bash
+python financial_fraud.py
+```
+
+Expected output: risk scores, AML pattern detection results, and compliance verdicts for
+each evaluated transaction trace.
+
+## Samples
+
+### Financial Services
+
+| File | Scenario | Description |
+|------|----------|-------------|
+| `financial_fraud.py` | Fraud analysts validating detection models | Risk scoring accuracy and anti-money-laundering pattern detection against labeled transaction data. |
+| `financial_trading.py` | Compliance officers auditing trading assistants | SOX suitability checks, fiduciary duty evaluation, and regulatory compliance for AI-assisted trading recommendations. |
+
+### Healthcare
+
+| File | Scenario | Description |
+|------|----------|-------------|
+| `healthcare_clinical.py` | Clinical informatics teams deploying decision support | Medical accuracy, drug interaction detection, and guideline adherence for clinical AI outputs. |
+
+### Insurance
+
+| File | Scenario | Description |
+|------|----------|-------------|
+| `insurance_claims.py` | Claims adjusters validating AI-assisted processing | Coverage determination accuracy and settlement fairness evaluation for automated claims workflows. |
+| `insurance_underwriting.py` | Underwriting teams auditing risk models | Risk assessment accuracy and fair lending compliance for AI-driven underwriting decisions. |
+
+### Legal
+
+| File | Scenario | Description |
+|------|----------|-------------|
+| `legal_contracts.py` | Legal teams reviewing AI-assisted contract analysis | Clause detection accuracy, risk flag identification, and obligation extraction for contract review tools. |
+| `legal_research.py` | Attorneys validating research assistants | Citation accuracy, jurisdictional correctness, and precedent relevance for legal research AI. |
+
+### Government
+
+| File | Scenario | Description |
+|------|----------|-------------|
+| `government_citizen.py` | Public sector teams deploying citizen-facing AI | Regulatory accuracy, accessibility compliance, equity assessment, and plain-language evaluation for government services. |
+
+### Retail
+
+| File | Scenario | Description |
+|------|----------|-------------|
+| `retail_recommender.py` | Product teams auditing recommendation engines | Recommendation relevance, safety filtering, and bias detection for AI-powered product suggestions. |
+| `retail_support.py` | Customer experience teams evaluating support bots | Response accuracy, tone appropriateness, and resolution quality for AI customer service agents. |
+
+## Expected Behavior
+
+Each sample loads domain-specific test data, creates traces representing AI interactions in
+that vertical, and evaluates them with industry-appropriate judges. Results include per-criterion
+scores and compliance verdicts relevant to the regulatory framework of each domain.

+# Integration Samples
+
+Most AI applications interact with LLMs through provider-specific SDKs such as OpenAI or
+Anthropic. These samples demonstrate how to instrument those API calls with LayerLens tracing
+and run post-completion evaluations -- without modifying your existing provider integration
+code. This enables teams to add observability and quality evaluation to production LLM
+calls with minimal effort.
+
+## Prerequisites
+
+```bash
+pip install layerlens --index-url https://sdk.layerlens.ai/package
+export LAYERLENS_STRATIX_API_KEY=your-api-key
+```
+
+Each sample requires the corresponding provider SDK and API key:
+
+| Sample | Additional Dependencies |
+|--------|------------------------|
+| `openai_traced.py` | `pip install openai` and `OPENAI_API_KEY` |
+| `anthropic_traced.py` | `pip install anthropic` and `ANTHROPIC_API_KEY` |
+| `openai_instrumented.py` | `pip install openai` and `OPENAI_API_KEY` |
+| `langchain_instrumented.py` | `pip install openai langchain-openai langchain-core` and `OPENAI_API_KEY` |
+
+## Quick Start
+
+Start with `openai_traced.py` if you use OpenAI, or `anthropic_traced.py` for Anthropic:
+
+```bash
+export OPENAI_API_KEY=your-openai-key
+python openai_traced.py
+```
+
+Expected output: the script makes an LLM API call, automatically captures the interaction
+as a LayerLens trace (including prompt, completion, token usage, and latency), runs a
+post-completion evaluation, and prints the trace ID and evaluation scores.
+
+## Samples
+
+| File | Scenario | Description |
+|------|----------|-------------|
+| `openai_traced.py` | Teams using OpenAI GPT models in production | Wraps an OpenAI chat completion call with LayerLens tracing, captures the full request/response cycle, and runs a post-completion evaluation with safety and relevance judges. |
+| `anthropic_traced.py` | Teams using Anthropic Claude models in production | Wraps an Anthropic message API call with LayerLens tracing, captures the full request/response cycle, and runs a post-completion evaluation with safety and relevance judges. |
+| `openai_instrumented.py` | Teams adopting auto-instrumentation for OpenAI | Uses `instrument_openai()` and the `@trace` decorator from `layerlens.instrument` to automatically capture all OpenAI calls as spans -- no manual trace upload needed. |
+| `langchain_instrumented.py` | Teams running LangChain LCEL chains | Uses `LangChainCallbackHandler` from `layerlens.instrument` to auto-capture chain execution, LLM calls, and prompt/completion data from LangChain pipelines. |
+
+## Expected Behavior
+
+Each sample makes a real API call to the respective provider, so valid provider credentials
+are required. The trace is uploaded to your LayerLens workspace and the evaluation results
+are printed to stdout. Both samples follow the same pattern, making it straightforward to
+adapt the approach to additional providers.

+# MCP Server
+
+The Model Context Protocol (MCP) server exposes LayerLens capabilities as tools that can be
+consumed by Claude, Cursor, VS Code Copilot, and any other MCP-compatible client. This enables
+AI assistants to directly query traces, run evaluations, and manage judges through natural
+language -- turning LayerLens into an interactive quality assurance co-pilot within your
+development environment.
+
+## Prerequisites
+
+```bash
+pip install layerlens --index-url https://sdk.layerlens.ai/package mcp
+export LAYERLENS_STRATIX_API_KEY=your-api-key
+```
+
+## Quick Start
+
+Run the server in stdio mode for use with Claude Code or other MCP clients:
+
+```bash
+python layerlens_server.py
+```
+
+The server will start and wait for MCP protocol messages on stdin/stdout.
+
+## Available Tools
+
+| Tool | Description |
+|------|-------------|
+| `list_traces` | List recent traces with optional filters (date range, status, model). |
+| `get_trace` | Retrieve a single trace by ID, including all spans and metadata. |
+| `run_evaluation` | Run a trace evaluation using a specified judge. |
+| `get_evaluation` | Fetch evaluation results by evaluation ID. |
+| `create_judge` | Create a new AI judge with custom criteria. |
+| `list_judges` | List all available judges in the workspace. |
+
+## Configuration
+
+### Claude Code
+
+Add the following to your MCP configuration file:
+
+```json
+{
+  "mcpServers": {
+    "layerlens": {
+      "command": "python",
+      "args": ["samples/mcp/layerlens_server.py"],
+      "env": {
+        "LAYERLENS_STRATIX_API_KEY": "your-api-key"
+      }
+    }
+  }
+}
+```
+
+### Other MCP Clients
+
+Any MCP-compatible client can connect to this server using stdio transport. Consult your
+client's documentation for the configuration format, and point it to `layerlens_server.py`
+with the required environment variable.
+
+## Expected Behavior
+
+Once connected, the MCP client will discover the available tools and make them accessible
+through its interface. For example, in Claude Code you can ask "list my recent traces" or
+"evaluate trace abc-123 with the safety judge" and the assistant will invoke the
+corresponding LayerLens tool.

+# Modality Samples
+
+AI applications produce content in many forms -- text, structured documents, brand-sensitive
+marketing copy -- and each form demands specialized evaluation criteria. These samples
+demonstrate how to apply modality-specific judges that go beyond generic quality scoring to
+assess the unique attributes of each content type: factual accuracy for text, brand alignment
+for marketing content, and structural integrity for extracted documents.
+
+## Prerequisites
+
+```bash
+pip install layerlens --index-url https://sdk.layerlens.ai/package
+export LAYERLENS_STRATIX_API_KEY=your-api-key
+```
+
+## Quick Start
+
+Start with `text_evaluation.py` for the most common modality. It applies safety, relevance,
+and factual accuracy judges to a text completion:
+
+```bash
+python text_evaluation.py
+```
+
+Expected output: per-judge scores and a pass/fail verdict for each evaluation dimension.
+
+## Samples
+
+| File | Scenario | Description |
+|------|----------|-------------|
+| `text_evaluation.py` | Content teams validating chatbot or assistant responses | Evaluates text completions against safety, relevance, and factual accuracy judges. Suitable as a baseline for any text-generating application. |
+| `brand_evaluation.py` | Marketing teams enforcing brand guidelines at scale | Evaluates content against brand voice, tone, and visual identity criteria. Useful for organizations that require consistent messaging across AI-generated outputs. |
+| `document_evaluation.py` | Data engineering teams validating document pipelines | Evaluates document extraction accuracy, field completeness, and structural integrity. Applies to OCR, PDF parsing, and other document-processing workflows. |
+
+## Expected Behavior
+
+Each sample creates a trace representing the modality-specific content, applies the relevant
+judges, and prints a scored summary. Brand and document evaluations will produce dimension-level
+breakdowns in addition to the aggregate score.

+# OpenClaw Agent Evaluation -- LayerLens Python SDK
+
+Trace, evaluate, and monitor [OpenClaw](https://openclaw.ai/) autonomous AI agents using the LayerLens evaluation platform.
+
+[OpenClaw](https://openclaw.ai/) is an open-source autonomous AI agent (60,000+ GitHub stars) that runs locally on your machine and uses messaging platforms (Telegram, Discord, WhatsApp, Slack) as its UI. It executes real tasks: shell commands, browser automation, email, calendar, and file operations -- all driven by a skill system with YAML-configured capabilities.
+
+Each OpenClaw agent is governed by a **soul.md** file -- a markdown spec that defines the agent's personality, ethical constraints, and tool boundaries. Think of it as a constitution for the agent's behavior.
+
+LayerLens integrates with OpenClaw at two levels:
+
+- **Tracing** -- capture every agent execution (input task, output result, metadata) as a LayerLens trace for auditability and analysis.
+- **Evaluation** -- score agent outputs with AI judges for safety, accuracy, helpfulness, and any custom quality dimension.
+
+---
+
+## Prerequisites
+
+```bash
+pip install layerlens --index-url https://sdk.layerlens.ai/package openclaw
+export LAYERLENS_STRATIX_API_KEY=your-api-key
+```
+
+All samples gracefully fall back to simulated data when OpenClaw is not installed or not running, so you can explore the LayerLens evaluation workflow without a live agent.
+
+---
+
+## Quick Start
+
+```bash
+# Run a single traced execution with evaluation
+python samples/openclaw/trace_agent_execution.py
+
+# Compare LLM backends for agent quality
+python samples/openclaw/compare_agent_models.py
+
+# Run a cage match between models
+python -m samples.openclaw.cage_match --models claude-sonnet-4-20250514,gpt-4o,deepseek-v3
+
+# Red-team test an agent against its soul.md
+python -m samples.openclaw.soul_redteam --models claude-sonnet-4-20250514,gpt-4o
+```
+
+---
+
+## Integration Samples
+
+End-to-end examples showing how to connect OpenClaw agents with LayerLens tracing and evaluation.
+
+| Sample | Scenario |
+|--------|----------|
+| `trace_agent_execution.py` | Trace a single OpenClaw execution and evaluate with a quality judge |
+| `evaluate_skill_output.py` | Run test prompts against a skill, evaluate with safety/accuracy/helpfulness judges, print quality report |
+| `monitor_agent_safety.py` | Execute a mix of safe and adversarial prompts, flag safety failures, print incident report |
+| `compare_agent_models.py` | Run the same tasks on multiple LLM backends, evaluate all, print a comparison table |
+
+---
+
+## Advanced Evaluation Patterns
+
+Deeper evaluation patterns for assessing OpenClaw agents across quality, safety, and alignment dimensions. Each demo uses the `_runner.py` base class which provides both OpenClaw execution (via `execute_with_openclaw()`) and LayerLens tracing/evaluation. All demos support `--no-sdk` for offline mode and `--json` for structured output.
+
+| Sample | Question It Answers | Scenario |
+|--------|---------------------|----------|
+| `cage_match.py` | Which LLM backend should my OpenClaw agent use for this skill? | Dispatch a task to N OpenClaw agents with different model backends, judge outputs side-by-side, publish a ranked leaderboard |
+| `code_gate.py` | Is the code my OpenClaw agent produces safe to execute? | Coder-Reviewer-Tester-Judge pipeline with a PASS/FAIL gate before code runs on your machine |
+| `heartbeat_benchmark.py` | Has my OpenClaw agent's performance degraded after a model update? | Versioned task batteries with drift detection to catch regressions before they affect agent behavior |
+| `content_observer.py` | What is the aggregate quality of content my OpenClaw agents produce? | Stratified content sampling for population-level quality monitoring across communities (descended from the Moltbook/Moltbot content quality system) |
+| `skill_auditor.py` | Does this OpenClaw skill attempt unauthorized actions? | Sandbox execution with honeypot decoys to detect data exfiltration, privilege escalation, and unauthorized outbound requests |
+| `soul_redteam.py` | Does my OpenClaw agent stay aligned with its soul.md constraints? | Adversarial probes targeting soul spec constraints with ALIGNED/DRIFT/VIOLATION verdicts |
+
+### What is a Soul Spec?
+
+OpenClaw agents are configured with a `soul.md` file that acts as the agent's constitution. It defines:
+
+- **Purpose** -- what the agent is for
+- **Persona** -- how the agent communicates
+- **Ethical Constraints** -- what the agent must never do
+- **Tool Boundaries** -- which tools the agent can access
+
+The `soul_redteam.py` demo probes whether an agent faithfully follows its soul spec under adversarial pressure, while `skill_auditor.py` tests whether individual skills respect the boundaries defined in the soul spec.
+
+### Content Observer Heritage
+
+The `content_observer.py` demo descends from the "Moltbook Observer" -- a population-level content quality monitoring system originally built for Moltbook (later rebranded Moltbot), an AI-powered social platform. The sampling strategies, karma-tier weighting, and community-level breakdowns reflect real patterns from monitoring AI-generated content at scale.
+
+---
+
+## LayerLens Skill for OpenClaw
+
+The `layerlens_skill/` directory contains an OpenClaw skill that lets agents interact with LayerLens directly. Install it by copying to your OpenClaw skills directory:
+
+```bash
+cp -r samples/openclaw/layerlens_skill ~/.openclaw/skills/layerlens
+```
+
+Then ask your agent:
+
+```
+Evaluate the last response for safety using LayerLens.
+```
+
+The skill calls `scripts/evaluate.py` which accepts input via arguments or JSON on stdin and returns structured results:
+
+```bash
+# Direct usage
+python layerlens_skill/scripts/evaluate.py \
+  --input "What is 2+2?" \
+  --output "2+2 is 4." \
+  --goal "factual accuracy"
+
+# Via stdin
+echo '{"input": "What is 2+2?", "output": "4", "goal": "accuracy"}' \
+  | python layerlens_skill/scripts/evaluate.py
+```
+
+### Skill Files
+
+| File | Purpose |
+|------|---------|
+| `layerlens_skill/SKILL.md` | Skill definition with YAML frontmatter, description, and usage instructions |
+| `layerlens_skill/scripts/evaluate.py` | Evaluation script that uploads traces, creates judges, and returns JSON results |
+
+---
+
+## Supporting Modules
+
+The advanced evaluation demos share infrastructure in two sub-packages:
+
+### `judges/` -- Local Evaluation Judges
+
+| Module | Purpose |
+|--------|---------|
+| `comparative.py` | Side-by-side multi-model evaluator across 4 quality dimensions |
+| `code_quality.py` | Code quality evaluator with binary gate enforcement |
+| `benchmark.py` | Multi-method scoring against golden answers |
+| `population_quality.py` | Batch content quality evaluator for feed monitoring |
+| `behavioral_safety.py` | Multi-category threat assessment for skill auditing |
+| `alignment_fidelity.py` | Soul spec alignment evaluator with 3-tier verdicts |
+
+### `lib/` -- Shared Utilities
+
+| Module | Purpose |
+|--------|---------|
+| `code_pipeline.py` | Multi-stage code generation pipeline (Coder-Reviewer-Tester-Judge) |
+| `drift_detector.py` | Rolling-baseline performance drift detection engine |
+| `honeypot.py` | Decoy tools that log violation attempts |
+| `notifier.py` | Multi-channel alert and leaderboard publisher |
+| `probe_generator.py` | Adversarial probe factory for red-team testing |
+| `sampler.py` | Stratified post sampler for population monitoring |
+| `schemas.py` | Shared Pydantic schemas for request/response envelopes |
+| `soul_parser.py` | Soul.md markdown parser |
+| `task_battery.py` | Versioned benchmark task battery loader |
+
+---

+```
+
+Each sample follows this pattern:
+
+1. **Execute** -- run a task via the OpenClaw agent (or use simulated data).
+2. **Trace** -- upload the execution as a LayerLens trace.
+3. **Judge** -- create one or more judges with `client.judges.create(name=, evaluation_goal=)`.
+4. **Evaluate** -- run `client.trace_evaluations.create(trace_id=, judge_id=)`.
+5. **Results** -- poll with `poll_evaluation_results()` and display.
+

+
+## SDK Methods Used
+
+| Method | Purpose |
+|--------|---------|
+| `Stratix()` | Initialize the LayerLens client |
+| `client.traces.upload(path)` | Upload a JSONL trace file |
+| `client.judges.create(name=, evaluation_goal=)` | Create an evaluation judge |
+| `client.judges.get_many()` | List existing judges |
+| `client.trace_evaluations.create(trace_id=, judge_id=)` | Start an evaluation |
+| `client.trace_evaluations.get_results(id)` | Retrieve evaluation results |

+Compare Agent Models -- LayerLens + OpenClaw
+=============================================
+Compares different LLM backends for an OpenClaw agent by executing the
+same tasks on each model, uploading all executions as traces, evaluating
+with consistent judges, and printing a comparison table.
+
+Workflow:
+  1. Create OpenClaw agents with different model backends.
+  2. Execute the same set of tasks on each agent.
+  3. Upload all executions as LayerLens traces with model metadata.
+  4. Evaluate all traces with the same judges.
+  5. Print a comparison table showing which model performed best.
+
+Prerequisites:
+    pip install layerlens --index-url https://sdk.layerlens.ai/package openclaw
+    export LAYERLENS_STRATIX_API_KEY=your-api-key
+
+Usage:
+    python compare_agent_models.py

+Content Observer -- OpenClaw Population-Level Content Quality Monitor
+=======================================================================
+
+Monitors the quality of AI-generated content produced by OpenClaw-powered
+agents by sampling posts across communities and karma tiers, evaluating
+them through the PopulationQualityJudge, and generating an intelligence
+report.
+
+Heritage: Originally developed as the "Moltbook Observer" for monitoring
+content quality on Moltbook (later Moltbot), an AI-powered social
+platform.  Ported to use OpenClaw agents for content generation and
+LayerLens for evaluation.  The sampling and scoring logic descends from
+the population-level quality monitoring system built for Moltbook's
+content feed.

+# LayerLens Skill for OpenClaw
+
+This skill lets OpenClaw interact with the [LayerLens](https://layerlens.ai/)
+AI evaluation platform. Use it to upload traces of agent executions, create
+quality judges, run evaluations, and retrieve scored results.
+
+## Prerequisites
+
+Install the LayerLens Python SDK:
+
+```bash
+pip install layerlens --index-url https://sdk.layerlens.ai/package
+```
+
+Set your API key:
+
+```bash
+export LAYERLENS_STRATIX_API_KEY=your-api-key
+```
+
+## What This Skill Does
+
+When triggered, this skill:
+
+1. **Uploads a trace** -- captures the input (task) and output (agent response)
+   as a LayerLens trace with metadata about the execution context.
+2. **Creates a judge** -- defines an evaluation rubric based on the requested
+   quality dimension (safety, accuracy, helpfulness, etc.).
+3. **Runs an evaluation** -- scores the trace against the judge criteria.
+4. **Returns results** -- provides a pass/fail verdict, numeric score, and
+   reasoning explanation.
+
+## Usage
+
+Ask OpenClaw to evaluate an output:
+
+```
+Evaluate the last response for safety using LayerLens.
+```
+
+```
+Run a quality check on this output: "The capital of France is Berlin."
+```
+
+```
+Upload a trace of our conversation and score it for helpfulness.
+```
+
+## Evaluation Script
+
+The skill delegates to `scripts/evaluate.py`, which accepts input via stdin
+or command-line arguments:
+
+```bash
+# Via arguments
+python scripts/evaluate.py --input "What is 2+2?" --output "2+2 is 4." --goal "factual accuracy"
+
+# Via stdin (JSON)
+echo '{"input": "What is 2+2?", "output": "2+2 is 4.", "goal": "factual accuracy"}' | python scripts/evaluate.py
+```
+
+## SDK Reference
+
+The skill uses these LayerLens SDK methods:
+
+- `client.traces.upload(path)` -- upload a JSONL trace file
+- `client.judges.create(name=, evaluation_goal=)` -- create an evaluation judge
+- `client.trace_evaluations.create(trace_id=, judge_id=)` -- run an evaluation
+- `client.trace_evaluations.get_results(evaluation_id)` -- retrieve results
+
+See the [LayerLens Python SDK documentation](https://layerlens.ai/docs/sdk/python)
+for full API details.

+Monitor Agent Safety -- LayerLens + OpenClaw
+=============================================
+Continuous safety monitoring for an OpenClaw agent. Executes a batch of
+tasks (mix of safe and adversarial prompts), uploads each execution as a
+LayerLens trace, runs safety evaluation, and flags any that fail.
+
+Workflow:
+  1. Execute a batch of tasks including adversarial prompts.
+  2. Upload each execution as a trace.
+  3. Run safety evaluation on each trace.
+  4. Flag traces that fail safety checks.
+  5. Print an incident report.
+
+Prerequisites:
+    pip install layerlens --index-url https://sdk.layerlens.ai/package openclaw
+    export LAYERLENS_STRATIX_API_KEY=your-api-key
