The file
We split this CLAUDE.md into the rules it gives an agent
5 rules. About 0 are common, 4 are distinctive, and 1 is very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈4
Distinctive · estimate
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- could be automatic: a setting could enforce it
- Distinctive: line 67
Use pytest fixtures for common test setup
- Very specific: line 71
All code quality standards (linting, formatting, type checking) are defined in pyproject.toml.
- Distinctive: line 76
Update README.md for user-facing changes
- Distinctive: line 77
Keep CLAUDE.md concise (< 1500 tokens)
- Distinctive: line 84
Claude Code: Use existing Claude Code CLI (no API key needed)
≈ “Common” is an estimate: at least 1 in 5 of the 26,980 CLAUDE.md files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Drift Project
TDD framework for AI workflows - define agent/skill/command standards in .drift.yaml, validate project structure programmatically, iterate to compliance.
Tech Stack
- Language: Python 3.10+
- Package Manager: uv
- Core Dependencies: pydantic, anthropic, boto3, pyyaml, jsonschema
- Testing: pytest with 90%+ coverage requirement
- Linting: black, flake8, isort, mypy (see pyproject.toml for configuration)
Project Structure
src/drift/ # Main application code (cli, validation, models)
tests/ # Test suite (unit, integration)
.claude/ # Claude Code configuration (agents, skills, commands)Claude Code Setup
The .claude/ directory contains specialized configurations for AI agents:
Agents (.claude/agents/):
cicd.md- CI/CD automation and release managementdeveloper.md- Feature implementationqa.md- Test writing and coverage
Skills (.claude/skills/):
testing- pytest test suite creation (90%+ coverage)linting- Code quality (black, flake8, isort, mypy)python-docs- PEP 257 docstringscode-review- Quality assurancegithub-operations- GitHub automation via MCP
Commands (.claude/commands/):
/test- Run pytest tests/lint- Run linters/full-check- Run tests + linting/code-review- Comprehensive code review/create-pr- Create PR with quality validation/create-issue- Create well-structured GitHub issue
Key Commands
# Primary use - TDD workflow (define → validate → fix → iterate)
drift --no-llm # Fast programmatic validation
drift --format json # JSON output for CI/CD
drift --rules <names> # Validate specific rules only
drift list # List available rules
drift draft --target-rule <rule_name> [--output file.md] # Generate AI prompt
drift document --rules <rule_name> [--format html] # Generate documentation
# Development
./test.sh # Run tests (90%+ coverage)
./lint.sh [--fix] # Run linters
# Installation
uv pip install -e ".[dev]"Development Guidelines
Testing Requirements
- Minimum 90% coverage (enforced by pytest)
- Comprehensive test coverage for all new features
- Use pytest fixtures for common test setup
- Mock external API calls (Anthropic, AWS Bedrock, Claude Code CLI)
Code Quality
All code quality standards (linting, formatting, type checking) are defined in pyproject.toml. Run ./lint.sh before committing.
Documentation
- PEP 257 compliant docstrings
- Google-style format with custom parameter separator
- Update README.md for user-facing changes
- Keep CLAUDE.md concise (< 1500 tokens)
Provider Support
Drift supports multiple LLM providers:
- Anthropic API: Set
ANTHROPIC_API_KEY - AWS Bedrock: Configure with
aws configure - Claude Code: Use existing Claude Code CLI (no API key needed)
Configuration in .drift.yaml (see README.md for details).
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
