All generated code, explanations, and reviews must strictly adhere to these guidelines for clarity, correctness, maintainability, and efficiency. + +--- + +## Persona & Philosophy + +- **Role:** Principal Software Engineer (10+ years Python, Haskell) +- **Approach:** Write _exceptional code_—clear, correct, maintainable, and efficient. +- **Design bias:** Favor pure, immutable functions. Use dataclasses or OOP only when they reduce cognitive load. + +--- + +## 1. Guiding Principles + +Memorize and observe these six core principles in all output: + +| # | Principle | One-liner | +| --- | ------------------------ | --------------------------------------------------------------------- | +| 1 | Readability > cleverness | Descriptive names, linear flow, 100-char lines. | +| 2 | Typed by default | All public API fully type-annotated. Type-checking must pass. | +| 3 | Functional-first | Pure functions, immutability, higher-order helpers, minimal IO. | +| 4 | Judicious OOP | Small, final classes/protocols only when simpler than pure functions. | +| 5 | Deterministic & testable | pytest + hypothesis; ≥90% branch coverage; no hidden state. | +| 6 | Modern & lean | Python 3.10+, stdlib first, async for IO, profile before optimizing. | + +--- + +## 2. Concrete Coding Rules + +All generated code **must** satisfy the following checklist: + +### 2.1 Naming & Structure + +- Use `snake_case` for variables/functions, `PascalCase` for classes, `SCREAMING_SNAKE` for constants. +- Place library code under `src/yourpkg/`; tests under `tests/`. +- One public concept per module; re-export via `__all__`. + +### 2.2 Immutability & Data + +- Default to `@dataclass(frozen=True, slots=True)` for records. +- Use `tuple` and `frozenset` by default; mutable collections only where required. + +### 2.3 Async & Concurrency + +- Use `async/await` for all IO-bound work. +- Never block the event loop (no `time.sleep` or heavy CPU loops without `run_in_executor`). +- Prefer `asyncio.Semaphore` for rate limiting over raw `gather`. + +### 2.4 Error Handling + +- Never use bare `except:`; always catch only exceptions you can handle. +- Chain exceptions for context (`raise ... from err`). +- Differentiate between programmer errors (`assert`) and user errors (`ValueError`). + +### 2.5 Logging & Observability + +- Use the `logging` module, never `print`. +- All log entries must include: `event="action_name"`, `duration_ms`, and relevant IDs. + +### 2.6 Testing + +- All code must be covered by `pytest -q` and `pytest --cov=yourpkg --cov-branch` at ≥90%. +- Use `hypothesis` for all non-trivial data logic; always seed with `PYTHONHASHSEED`. +- All async code must be tested with `pytest.mark.asyncio`. + +### 2.7 Tooling & CI + +```shell +ruff check --select ALL --ignore D203,D213 # Google-style docs +ruff format # Like Black, but via Ruff +pyright # Strict mode +pre-commit run --all-files # As defined in .pre-commit-config.yaml +``` + +### 2.8 Dependencies & Packaging + +- All dependencies are pinned in `pyproject.toml` (`[project]`, `[tool.rye]`, or `[tool.poetry]`). +- For CLIs, expose entry points via `[project.scripts]`. +- Avoid heavy dependencies; justify and document any non-stdlib package. + +--- + +## 3. Documentation + +- All functions/classes require **Google-style docstrings** (`Args:`, `Returns:`, `Raises:`). +- The docstring summary line must be ≤72 chars. +- Include minimal, runnable usage examples, guarded by `if __name__ == "__main__"`. + +--- + +## 4. Commit & PR Etiquette + +- **Title:** Imperative present, ≤50 chars. +- **Body:** What + why (wrap at 72). +- Always link relevant issue refs (`Fixes #123`), and add benchmarks for perf-related changes. + +--- + +## 5. LLM Response Contract (ChatGPT Codex Only) + +- **All code** must be fenced as + + ````markdown + ```python + # code here + ``` + ```` + +- Obey every rule in section 2 (Coding Rules). +- If alternatives exist, list **Pros / Cons** after your primary solution. +- Provide **pytest** snippets for all new functions and public APIs. +- Explicitly **flag and explain** any deviation from these guidelines in reviews or diffs. + +--- + +## 6. Review Checklist (for agents and reviewers) + +- [ ] All public functions, classes, and modules are fully type-annotated. +- [ ] Names, file structure, and style match section 2. +- [ ] All tests pass locally, with ≥90% branch coverage (see CI status). +- [ ] Error handling is specific, contextual, and never uses bare `except:`. +- [ ] All log output uses the `logging` module with event/action context. +- [ ] No print statements or unapproved dependencies. +- [ ] All changes are documented and include minimal working examples. +- [ ] Commit and PR messages follow etiquette rules. + +--- + +## 7. Examples + +### Code Example + +```python +from dataclasses import dataclass + +@dataclass(frozen=True, slots=True) +class User: + """User account with immutable attributes. + + Args: + id: Unique user identifier. + name: Display name. + """ + id: int + name: str +``` + +### Pytest Example + +```python +import pytest +from yourpkg.models import User + +def test_user_is_immutable(): + user = User(id=1, name="Alice") + with pytest.raises(Exception): + user.id = 2 +``` + +### LLM Response Example + +```python +# Here is a functional utility following all standards: +def add_one(x: int) -> int: + """Return input incremented by one. + + Args: + x: An integer. + + Returns: + Integer one greater than x. + """ + return x + 1 + +# Pytest example: +def test_add_one(): + assert add_one(2) == 3 +``` + +**Pros**: Pure, fully typed, easily testable. +**Cons**: For very simple operations, docstrings may seem verbose, but aid maintainability. + +--- + +## 8.

It aims to ensure test code is readable, robust, and maintainable, and to enable agents to collaborate effectively with developers and automated systems. + +--- + +## Goals + +- Write **discoverable, idiomatic pytest tests** for Python codebases. +- Prefer **DAMP (Descriptive And Meaningful Phrases)** over excessive DRY, prioritizing readability. +- Validate **invariants and properties** rather than only asserting on outputs. +- Structure and document tests so that they are easy to understand and maintain. +- Integrate with standard Python project layouts and CI. + +--- + +## 1. Test Directory & File Structure + +- **Mirror code layout** in the test suite. + + - Example: + + ``` + src/ + your_package/ + core.py + tests/ + unit/ + test_core.py + integration/ + test_cli.py + ``` + +- Place fast unit tests in `tests/unit/`, and use `tests/integration/` for tests requiring I/O, external systems, or longer runtimes. +- Each test module should cover a single module or feature, and be named `test_.py`. + +--- + +## 2. Writing Readable Tests (DAMP > DRY) + +- **DAMP**: Be explicit. Favor clarity over clever abstractions; minor repetition is OK if it clarifies test intent. +- Only refactor repeated setup into fixtures or helpers when duplication would harm maintainability or understanding. +- When extracting helpers, keep them as close as possible to their use (within the same test file if feasible). +- Each test should **read as a specification** and explain "what" is being tested, not just "how". + +--- + +## 3. Testing Invariants & Properties + +- **Do not** only assert expected outputs for fixed inputs; also test fundamental properties and invariants. +- Examples: + + - Instead of only `assert sort([3,1,2]) == [1,2,3]`, also assert the result is sorted and is a permutation of the input. + - Use **property-based testing** (e.g., [hypothesis](https://hypothesis.readthedocs.io/)) for coverage of input space. + +- Prefer property-based tests for code with complex input domains, and classic example-based tests for regression or documentation. + +--- + +## 4. Pytest Conventions and Tools + +- **Fixtures**: Use `pytest` fixtures for dependencies and setup, not class-based `setUp`/`tearDown`. + + - Pass fixtures as function arguments to make dependencies explicit. + - Use scopes (`function`, `module`, etc.) to control resource lifetimes. + +- **Parametrize**: Use `@pytest.mark.parametrize` to test multiple scenarios clearly. +- **Exception Handling**: Use `pytest.raises` for asserting exceptions. +- **Floating Point**: Use `pytest.approx` for float comparisons. +- **Temporary Resources**: Use built-in fixtures like `tmp_path`, `monkeypatch`, `capsys`, and `caplog`. +- **Markers**: Mark slow, network, or integration tests for selective execution. + +--- + +## 5. Test Style Guidelines + +- Each test function must start with `test_`. +- Use **type hints** in tests for clarity. +- Prefer **AAA (Arrange, Act, Assert)** structure and use blank lines or comments to make test phases clear. +- Name test functions with descriptive behavior: + e.g., `test_parse_returns_empty_list_for_blank_input` +- Prefer **one assertion per behavior**, but multiple asserts are fine when related. +- Keep test data minimal yet realistic; use local factories or fixtures for complex setup. +- Avoid logic and branching in test code, except for explicitly asserting both outcomes. +- Docstrings are optional for trivial tests, but document non-obvious behaviors or fixtures. + +--- + +## 6. Example + +```python +import pytest +from your_package.math import fib + +@pytest.mark.parametrize("n, expected", [(0, 0), (1, 1), (7, 13)]) +def test_fib_known_values(n: int, expected: int) -> None: + """Test canonical Fibonacci numbers for low n.""" + result = fib(n) + assert result == expected + +@pytest.mark.parametrize("n", [10, 20, 30]) +def test_fib_monotonicity(n: int) -> None: + """Fibonacci sequence is non-decreasing.""" + assert fib(n) <= fib(n+1) + +from hypothesis import given, strategies as st + +@given(st.integers(min_value=2, max_value=100)) +def test_fib_upper_bound(n: int) -> None: + """Fibonacci number is always less than 2^n.""" + assert fib(n) < 2 ** n +``` + +--- + +## 7. Checklist for Agent-Generated Tests + +- [ ] Tests are in the correct directory and named for the module under test. +- [ ] DAMP style: explicit, not over-abstracted; repeated setup only refactored if necessary. +- [ ] Property-based and example-based tests are included where appropriate. +- [ ] Use `pytest` fixtures, parametrization, and markers idiomatically. +- [ ] Test names and docstrings (if present) describe intent. +- [ ] No direct I/O, sleeps, or network calls unless explicitly marked as integration. +- [ ] Tests are deterministic, hermetic, and CI-friendly. + +--- + +## References + +- [pytest documentation](https://docs.pytest.org/en/latest/) +- [Hypothesis property-based testing](https://hypothesis.readthedocs.io/) +- [OpenAI Codex documentation](https://github.com/openai/codex) +- [Python Testing in Practice](https://realpython.com/pytest-python-testing/) + +--- + +## Appendix: Prompts for Codex/ChatGPT + +- **Be specific**: Start with a clear comment, code snippet, or data sample. +- **Specify language and libraries**: e.g., `# Python 3.10, using pytest` +- **Provide example(s) and properties**: e.g., "Write pytest unit tests for this function, ensuring monotonicity and correct output for known inputs." +- **Comment style**: Use docstrings for function behavior, inline comments for assertions. + +--- + +**This file guides agents and automated tools to produce high-quality, maintainable Python tests in line with modern Python and pytest best practices.** diff --git a/LICENSE b/LICENSE index b3841f6..e5ad2c5 100644 --- a/LICENSE +++ b/LICENSE @@ -1,6 +1,6 @@ MIT License -Copyright (c) 2023 OpenAI +Copyright (c) 2025 OpenAI Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal diff --git a/Makefile b/Makefile new file mode 100644 index 0000000..f962a57 --- /dev/null +++ b/Makefile @@ -0,0 +1,54 @@ +.PHONY: sync +sync: + uv sync --all-extras --all-packages --group dev + +.PHONY: format +format: + uv run ruff format + uv run ruff check --fix + +.PHONY: lint +lint: + uv run ruff check + +.PHONY: mypy +mypy: + uv run mypy src + uv run mypy tests + uv run mypy evals + +.PHONY: tests +tests: + uv run pytest + +.PHONY: coverage +coverage: + + uv run coverage run --include="src/guardrails/*" -m pytest + uv run coverage xml --include="src/guardrails/*" -o coverage.xml + uv run coverage report --include="src/guardrails/*" -m --fail-under=95 + +.PHONY: snapshots-fix +snapshots-fix: + uv run pytest --inline-snapshot=fix + +.PHONY: snapshots-create +snapshots-create: + uv run pytest --inline-snapshot=create + +.PHONY: build-docs +build-docs: + uv run mkdocs build + +.PHONY: build-full-docs +build-full-docs: + uv run docs/scripts/translate_docs.py + uv run mkdocs build + +.PHONY: serve-docs +serve-docs: + uv run mkdocs serve +# +# .PHONY: deploy-docs +# deploy-docs: +# uv run mkdocs gh-deploy --force --verbose diff --git a/README.md b/README.md index c8502fc..2460f05 100644 --- a/README.md +++ b/README.md @@ -1,22 +1,213 @@ -# OpenSourceExample -Example configuration for repositories that will become open-source/source-available. +# OpenAI Guardrails -## Using the `trufflehog` Pre-Commit Hook -This repository includes a pre-commit hook that uses the `trufflehog` tool to scan your code for secrets before each commit.

Use the local installation methods below. + +## Quick Start: Using OpenAI Guardrails (TypeScript) + +### 1. Install Locally + +Clone the repository and install dependencies: +```bash +# From the root of the repo +cd guardrails-ts +npm install +npm run build +``` + +You can also install it into your own project from the local path: ```bash -pip3 install pre-commit +npm install /absolute/path/to/guardrails/guardrails-ts ``` -Before you can use the `trufflehog` pre-commit hook, you need to have the `trufflehog` tool installed. You can install it using the following command: + +### 2. Using the Guardrails Client in TypeScript + +The TypeScript client now provides a high-level API similar to Python: + +```typescript +import { GuardrailsOpenAI } from '@guardrails/guardrails-ts'; +import * as path from 'path'; +// Create a GuardrailsOpenAI client with your config +const client = await GuardrailsOpenAI.create(path.resolve('guardrails_config.json'), { + apiKey: process.env.OPENAI_API_KEY, +}); +try { + const response = await client.chat.completions.create({ + model: 'gpt-5', + messages: [{ role: 'user', content: '...' }], + }); + console.log(response.llm_response.choices[0].message.content); +} catch (e) { + // Handle blocked or flagged content + console.error('Guardrail triggered:', e); +} +// Example: Using the new OpenAI Responses API with Guardrails +try { + const resp = await client.responses.create({ + model: 'gpt-5', + input: '...', + // Optionally, add file_search or other tool arguments as needed + }); + console.log(resp.llm_response.output_text); +} catch (e) { + console.error('Guardrail triggered (responses API):', e); +} +``` + +### 3. CLI Usage + +You can also use the CLI for validation and evaluation: + ```bash -brew install trufflehog +# Run directly with npm (from guardrails-ts directory) +npm run cli -- --help +npm run cli -- validate config.json +npm run cli -- eval --config-path config.json --dataset-path dataset.jsonl + +# Or install globally for CLI access +npm install -g . +guardrails-ts --help +guardrails-ts validate config.json +guardrails-ts eval --config-path config.json --dataset-path dataset.jsonl ``` -Once you have both tools installed, you can run `pre-commit install` to install the pre-commit hooks in your repository: -### Using the Pre-Commit Hook -Once you have the `trufflehog` tool installed and have added the patterns you want to search for (OAI keys added by default), you can use the pre-commit hook to automatically scan your code before each commit.

Running Examples + +```bash +# Build the package first +npm run build + +# Run example scripts (from guardrails-ts/examples) +cd examples +npx tsx simple-runtime-usage.ts +npx tsx guardrails-demo.ts +``` + +--- + +## What Does the TypeScript Package Provide? + +- **GuardrailsOpenAI** and **GuardrailsAzureOpenAI**: Drop-in replacements for OpenAI's `OpenAI` and `AzureOpenAI` clients, with automatic guardrail enforcement (mirrors Python API). +- **Automatic input/output validation**: Guardrails are applied to all relevant API calls (e.g., `chat.completions.create`, `responses.create`, etc.). +- **Configurable guardrails**: Choose which checks to enable, and customize their parameters via the JSON spec. +- **Tripwire support**: Optionally block or mask unsafe content, or just log/flag it for review. +- **CLI tool**: Validate configs, run evaluations, and more from the command line. +- **Evaluation framework**: Test guardrail performance on datasets and measure metrics like precision, recall, and F1 scores. + +--- + +## Available Guardrails + +Below is a list of all built-in guardrails you can configure. Each can be enabled/disabled and customized in your JSON spec. + +| Guardrail Name | Description | +|-------------------------|-------------| +| **Keyword Filter** | Triggers when any keyword appears in text. | +| **Competitors** | Checks if the model output mentions any competitors from the provided list. | +| **Jailbreak** | Detects attempts to jailbreak or bypass AI safety measures using techniques such as prompt injection, role-playing requests, system prompt overrides, or social engineering. | +| **Moderation** | Flags text containing disallowed content categories (e.g., hate, violence, sexual, etc.) using OpenAI's moderation API. | +| **NSFW Text** | Detects NSFW (Not Safe For Work) content in text, including sexual content, hate speech, violence, profanity, illegal activities, and other inappropriate material. | +| **Contains PII** | Checks that the text does not contain personally identifiable information (PII) such as SSNs, phone numbers, credit card numbers, etc., based on configured entity types. | +| **Secret Keys** | Checks that the text does not contain potential API keys, secrets, or other credentials. | +| **Off Topic Prompts** | Checks that the content stays within the defined business scope. | +| **URL Filter** | Flags URLs in the text unless they match entries in the allow list. | +| **Custom Prompt Check** | Runs a user-defined guardrail based on a custom system prompt. Allows for flexible content moderation based on specific requirements. | +| **Anti-Hallucination** | Detects potential hallucinations in AI-generated text using OpenAI Responses API with file search. Validates claims against actual documents and flags factually incorrect, unsupported, or potentially fabricated information. | + +--- + +## License + +For the duration of this early access alpha, `guardrails` (including both the Python and TypeScript packages) is distributed under the Alpha Evaluation Agreement that your organization signed with OpenAI. + +Both the Python and TypeScript packages are intended to be MIT-licensed in the future, subject to change. + +## Disclaimers -The `trufflehog` tool will automatically scan your code for secrets and reject the commit if any are found.
