another total refactor

[jeremymanning]

anthropic recently launched claude skills, which has the potentially to substantially simplify the implementation of this toolbox.

a catch is that skills are only supported for claude models. the simplest solution would be to drop support for all non-anthropic platforms, and open a new issue to add support back in at a future date, when other platforms (hopefully) adopt support for skills

this greatly simplifies many aspects of the toolbox:

• model registry: contains only anthropic models: opus 4 handles the most complex tasks; sonnet 4.5 provides a sensible default, and haiku 4.5 can do simple tasks cheaply.
• tools registry: now just a wrapper and interface for anthropic skills. the example skills repo contains a good base set of skills that we can directly copy. importantly, one of the "meta" skills included is a tool for creating new skills! so we can call on this if an appropriate skill isn't available.
• credentials management: only need support for anthropic API keys
• cost estimation: only need support for anthropic models
• local resource estimation: no longer needed, since all models run on anthropic's servers
• parallel tasks can be launched as parallel agents

so we can do a total refactor to cut away nearly all of the toolbox code, and substantially simplify the remaining code. the key will be do develop a reliable core set of functions to compile the pipeline (this must be done and managed automatically-- pipelines should be compiled to langgraphs) and then called.

Technical Design Document: Claude Skills-Based Orchestrator Refactor

Executive Summary

This document outlines a comprehensive refactor of the Orchestrator framework to leverage Anthropic's Claude Skills system. The refactor will dramatically simplify the codebase by:

• Removing support for non-Anthropic models (temporarily)
• Replacing the complex tools registry with a skills-based system
• Implementing automatic skill creation with multi-agent review
• Compiling pipelines directly to LangGraph without LLM prompting
• Creating a comprehensive suite of example pipelines

Latest Anthropic Models (2025)

Model Selection Strategy

• Claude Sonnet 4.5 (Released Sep 2025): Primary orchestrator model

  • World's best coding model with 1M token context window
  • Optimal for building complex agents and computer use
  • Default for skill creation and pipeline orchestration

• Claude Opus 4.1 (Released Aug 2025): Review and analysis model

  • Most powerful Claude model for deep analysis
  • Used for comprehensive skill review and validation
  • Complex reasoning and instruction adherence

• Claude Haiku 4.5 (Released Oct 2025): High-speed validation

  • 90% of Sonnet 4.5's performance at 1/3 the cost
  • Used for quick validation checks and simple tasks
  • Ideal for high-volume, cost-sensitive operations

Leveraging Claude Agent SDK

The implementation will build upon the Claude Agent SDK, which provides the same infrastructure that powers Claude Code, ensuring production-ready agent capabilities from day one.

7. Testing Strategy

7.1 Real-World Testing Requirements

class RealWorldTestFramework:
    """All tests use real resources - NO MOCKS."""

    TEST_REQUIREMENTS = {
        "apis": {
            "anthropic": "Real API calls with actual models",
            "web_services": "Real HTTP requests to live services",
            "databases": "Real database connections and operations"
        },
        "files": {
            "creation": "Actually create files on disk",
            "reading": "Read real files with actual content",
            "downloading": "Download real files from internet"
        },
        "models": {
            "execution": "Run actual model inference",
            "validation": "Verify real model outputs",
            "costs": "Track actual API costs"
        }
    }

7.2 Validation Criteria

• Every skill must have at least 3 real-world test cases
• Test outputs must be manually verifiable
• Visual outputs require screenshots for validation
• API responses must be validated for format and content
• File operations must produce verifiable artifacts

8. Migration Plan

8.1 Deprecation Strategy

class MigrationHelper:
    """Helps migrate from old system to new."""

    def migrate_pipeline(self, old_pipeline):
        """Convert old pipeline format to new skills-based format."""
        # Map old tools to new skills
        # Convert parameters
        # Update syntax
        return new_pipeline

    def migrate_tool_to_skill(self, old_tool):
        """Convert old tool definition to skill."""
        # Extract capabilities
        # Create SKILL.md
        # Generate examples
        # Add to registry
        return new_skill

8.2 Backwards Compatibility

• Temporary adapters for critical old pipelines
• Gradual migration with deprecation warnings
• Tool-to-skill mapping for common operations

9. Success Metrics

9.1 Simplification Metrics

• Code Reduction: Target 70% reduction in codebase size
• Dependency Reduction: From ~50 dependencies to <10
• Compilation Speed: Direct compilation without LLM = 100x faster
• Maintenance Overhead: 80% reduction in complexity

9.2 Capability Metrics

• Skill Coverage: 100% of example pipeline needs covered
• Creation Success: 95% of new skills work on first review cycle
• Test Coverage: 100% real-world test coverage (0% mocks)
• Pipeline Success: All example pipelines execute successfully

10. Risk Mitigation

10.1 Technical Risks

• Risk: Claude Skills API changes

  • Mitigation: Version lock, abstraction layer

• Risk: Skill creation failures

  • Mitigation: Fallback to manual creation, comprehensive examples

• Risk: Real-world test costs

  • Mitigation: Rate limiting, cost tracking, budget alerts

10.2 Migration Risks

• Risk: Breaking existing pipelines

  • Mitigation: Phased rollout, compatibility layer

• Risk: User adoption challenges

11. Cost Optimization Strategy

11.1 Model Selection for Cost Efficiency

class CostOptimizer:
    """Intelligently route tasks to appropriate models based on complexity."""

    MODEL_COSTS = {
        "haiku-4.5": {"input": 1.0, "output": 5.0},  # Per million tokens
        "sonnet-4.5": {"input": 3.0, "output": 15.0},
        "opus-4.1": {"input": 15.0, "output": 75.0}  # Estimated
    }

    def select_model(self, task_complexity, budget_priority):
        """
        Route tasks intelligently:
        - Haiku 4.5: Simple validations, formatting (90% of Sonnet performance)
        - Sonnet 4.5: Skill creation, agent coordination (best for complex agents)
        - Opus 4.1: Critical reviews, deep analysis (when quality is paramount)
        """

11.2 Leveraging Platform Features

• Prompt Caching: 90% cost savings on repeated contexts
• Batch Processing: 50% cost savings for non-time-critical tasks
• Memory Capabilities: Reduce redundant processing across sessions
• Context Window Management: Sonnet 4.5's 1M token window for complex pipelines

Conclusion

This refactor represents a fundamental simplification of the Orchestrator framework, leveraging Claude Skills to create a more maintainable, powerful, and user-friendly system. By focusing exclusively on Anthropic models initially, we can deliver a robust implementation quickly, with the option to extend support to other platforms as they adopt similar capabilities.

The emphasis on real-world testing without mocks ensures reliability, while the automatic skill creation workflow enables rapid capability expansion. The comprehensive example pipelines will demonstrate the system's power and provide templates for users to build upon.

Updated Technical Design Document (Version 2)

Based on feedback, I've created an updated design incorporating:

• Registry management in ~/.orchestrator directory
• Integration points from ROMA and AgnoAgents
• Advanced pipeline control flow (loops, conditionals, state management)
• Compile-time verification
• Pipeline objects with .help() method

Key Updates in V2:

1. Registry Management

• Default skills pool stored in main repository under orchestrator/registry/
• On install, copies to ~/.orchestrator/skills/registry.yaml
• New skills created in ~/.orchestrator/skills/<name>/
• Model registry at ~/.orchestrator/models/registry.yaml

2. ROMA Integration (with attribution)

• Four-stage processing pattern for skill creation (Atomize, Plan, Execute, Aggregate)
• E2B sandbox integration for secure code execution during testing
• Hierarchical state management for nested pipeline execution

3. AgnoAgents Integration

• Performance-optimized skill instantiation (<10ms target)
• MCP (Model Context Protocol) support
• Privacy-first architecture (all processing within user infrastructure)

4. Advanced Control Flow

• For loops with parallelization option
• While loops with conditions and max iterations
• Conditionals (if/elif/else) for routing and conditional execution
• State management with variables attached to LangGraph nodes
• Temporary products stored as state attributes or files

5. Compile-Time Verification

• Syntax validation for YAML structure
• Variable reference checking (excluding programmatic variables)
• Model existence verification
• Skill availability checking (creates missing skills automatically)
• Automatic .help() generation using Sonnet 4.5

I'll post the complete document in the following comments...

Key Integration Points:

1. From ROMA:

   • Four-stage processing (Atomize, Plan, Execute, Aggregate)
   • E2B sandbox for secure execution
   • Hierarchical state management
   • Parallel processing with dependencies

2. From AgnoAgents:

   • <10ms skill instantiation target
   • MCP protocol support
   • Privacy-first (all processing local)
   • Stateless, horizontally scalable

3. Our Innovations:

   • Skills registry in ~/.orchestrator
   • Direct YAML to LangGraph compilation
   • Advanced control flow in pipelines
   • Real-world testing with NO MOCKS

This V2 design creates a powerful yet simple framework that leverages the best ideas from ROMA and AgnoAgents while maintaining focus on the Claude Skills integration.

[jeremymanning]

Note: "improving tests until they pass" isn't valid-- if the tests have errors they should be corrected, but if it's just that the tests aren't passing the actual toolbox code (i.e., whatever is being tested) should be fixed. I.e., the pipeline should push towards correct (intended) functionality, not solely getting tests to pass regardless of whether the desired functionality is achieved.

[jeremymanning]

Other notes:

1. we should implement this refactor in a new branch. After creating the branch, get rid of old code, notes, documentation, and tests-- i.e., anything that can't be directly used in the refactor.
2. in crafting an implementation plan, plan out carefully which tasks can be parallelized (farmed off to multiple agents that work in parallel), along with whether there are any execution order dependencies.
3. if any tasks require more sophisticated planning, the agents that execute those tasks should use the opus model. all other tasks should be executed in agents that use the sonnet-4.5 model. use the main (current) thread to track progress. on completion, agents should return a summary and update to the main thread. on completion of a task, also spawn a new sonnet-4.5 agent to review the completed task and update or fix things needed. the main (current) thread should use the TodoWrite tool to manage the complete task sequence, and should preserve context by using agents to accomplish the individual tasks (that way the agents use their context, but the main thread's context is filled only by updates from the agents).

Claude Skills Refactor - Comprehensive Implementation Plan

Overview

I've completed a thorough analysis of the codebase and drafted a comprehensive implementation plan for the Claude Skills refactor. This plan emphasizes real-world testing with NO mocks or simulations as requested.

Key Analysis Documents Created

1. Comprehensive Codebase Analysis - 890 lines analyzing all 17 modules
2. Refactor Integration Points - 546 lines with specific file paths and changes
3. Analysis Summary - Executive overview with risk assessment

Implementation Plan Highlights

Core Principles

• ✅ NO MOCK TESTS - All tests use real Anthropic API calls
• ✅ Real Data Processing - Actual files, web resources, databases
• ✅ Manual Verification - Screenshots and artifacts for validation
• ✅ E2B Sandbox Integration - Secure code execution during testing

Phase Breakdown (6 weeks total)

Phase 1: Core Infrastructure (Days 1-7)

• Simplify model registry to Anthropic-only (Opus 4.1, Sonnet 4.5, Haiku 4.5)
• Implement ~/.orchestrator registry management
• Remove non-Anthropic model support

Phase 2: Skills System (Days 8-14)

• Implement ROMA pattern for skill creation (Atomize, Plan, Execute, Aggregate)
• Build real-world testing framework
• Create skill registry structure

Phase 3: Pipeline Compilation (Days 15-21)

• Direct YAML to LangGraph compilation (no LLM prompting)
• Automatic skill creation for missing capabilities
• Advanced control flow (for/while loops, conditionals)

Phase 4: Example Pipelines (Days 22-28)

• Code review pipeline with real test generation
• Deep research pipeline with source verification
• Multi-agent problem solver
• 5+ additional showcase pipelines

Phase 5: Testing Strategy (Days 29-35)

• Real API integration tests
• E2B sandbox execution tests
• Performance benchmarking with real data
• Cost tracking and optimization

Phase 6: Documentation & Migration (Days 36-42)

• User documentation
• Migration tools for existing pipelines
• API reference documentation

Real-World Testing Examples

# Example: Real API test (NO MOCKS)
def test_claude_skill_creation_real():
    \"\"\"Create a skill using real Claude API.\"\"\"
    creator = SkillCreator(api_key=os.getenv(\"ANTHROPIC_API_KEY\"))
    
    # Real skill creation
    skill = creator.create_skill(
        capability=\"Extract tables from PDF\",
        test_with_real_pdf=True
    )
    
    # Download real PDF
    pdf_content = requests.get(\"https://example.com/sample.pdf\").content
    
    # Execute with real data
    result = skill.execute(pdf_content)
    assert len(result.tables) > 0
    
    # Save for manual verification
    result.save_screenshot(\"./test_outputs/result.png\")

Key Architectural Changes

Simplified Model Registry

ANTHROPIC_MODELS = {
    \"opus-4.1\": {
        \"id\": \"claude-opus-4-1-20250805\",
        \"role\": \"review_and_analysis\",
        \"context_window\": 200000
    },
    \"sonnet-4.5\": {
        \"id\": \"claude-sonnet-4-5\",
        \"role\": \"orchestrator\",
        \"context_window\": 1000000  # 1M tokens!
    },
    \"haiku-4.5\": {
        \"id\": \"claude-haiku-4-5\",
        \"role\": \"simple_tasks\",
        \"context_window\": 200000
    }
}

Skill Auto-Creation Workflow

1. Pipeline requests capability
2. Sonnet 4.5 creates initial skill
3. Opus 4.1 reviews and refines
4. Real-world testing (NO MOCKS)
5. Manual verification with screenshots
6. Registration in ~/.orchestrator/skills

Expected Outcomes

• 70% code reduction (simplified architecture)
• 100x faster compilation (no LLM in compile path)
• 95% skill creation success rate (first attempt)
• 0% mock tests (all real-world validation)

Files Created for Review

• CLAUDE_SKILLS_REFACTOR_IMPLEMENTATION_PLAN.md - Full 42-day implementation plan
• COMPREHENSIVE_CODEBASE_ANALYSIS.md - Deep technical analysis
• REFACTOR_INTEGRATION_POINTS.md - Specific integration guidance
• ANALYSIS_SUMMARY.md - Executive overview

Next Steps

1. Please review this comprehensive plan
2. I'm ready to begin Phase 1 implementation upon approval
3. Daily progress updates will be posted here
4. Weekly demos can be scheduled for each completed phase

The plan ensures all testing uses real API integration and real data - absolutely no mocks or simulations. Every skill and pipeline will be validated with actual Anthropic API calls, real file processing, and manual verification through screenshots.

Ready to proceed with implementation upon your approval!
