Cross Agent Compatibility

Multi-agent projects must have compatible instruction sets — shared instructions must be agent-neutral, with agent-specific content isolated to dedicated files.

Antipatterns

• Referencing CLAUDE.md or .cursorrules by name in a shared instruction file. The check detects agent-specific filenames in shared files. Agent-specific content belongs in its own file.
• Mentioning .clinerules or copilot-instructions.md in a file that all agents read. Even factual references to agent-specific filenames violate neutrality in shared instructions.
• Writing agent-neutral prose but including an example that names a specific agent file. The check matches the filename pattern regardless of surrounding context.

# Coding Standards

Use `ruff` for formatting.
Run `pytest tests/` before committing.
Keep modules under 500 lines.

See `.cursorrules` for Cursor-specific settings.
Claude users should check `CLAUDE.md` for details.

Limitations

Checks for agent-specific filenames (CLAUDE.md, .cursorrules, copilot-instructions.md) referenced in content. Does not detect agent-specific terminology or conventions that don't mention filenames.
