Unwritten gives coding agents your team's unwritten rules. It mines git history to learn which files change together, then flags confident absences with evidence: "you changed A but not B — they co-change in 59 of 63 commits." No LLM, no config. IntelliSense for conventions: an MCP server for agents, plus a CLI for pre-commit hooks.

A CLI utility for rapid codebase diagnostics using git metadata.

tornhill is named in honor of Adam Tornhill, whose behavioral-code-analysis work — Code Maat and "Your Code as a Crime Scene" (temporal coupling, hotspots) — is the foundation of the git-signal engine here
