Common mistakes to avoid and best practices to follow.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Common Mistakes to Avoid ## ❌ DON'T - Use synchronous blocking calls in async functions - Omit type hints or use `Any` unnecessarily - Skip tests for new features - Forget `confirm=True` safety checks on mutating operations - Expose sensitive data in logs - Commit without running pre-commit hooks - Mix sync and async code improperly - Return untyped dicts when Pydantic models are appropriate - Ignore project guidelines (`CLAUDE.md`, `AGENTS.md`) when editing command/agent assets or MCP tool instructions ## ✅ DO - Use async/await consistently - Provide comprehensive type hints - Write tests first (TDD) - Implement dry-run mode for dangerous operations - Mask passwords and keys in logs - Run full test suite before committing - Use `async with` for resource management - Define Pydantic models for complex data structures - Follow project guidelines in `CLAUDE.md` and `AGENTS.md` for consistent development practices ## Quick Commands ```bash # Development uv run mcp dev src/main.py # Run with MCP Inspector # Testing pytest # Run all tests pytest -m unit # Unit tests only pytest -m integration # Integration tests only …

How to install
mdr add enuno/unifi-mcp-server/.cursor/rules/common-mistakes.mdc@sha256:72661660b353b03dThe line at the top of this page pins the label git:20260125.f453b7c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
