COMPLEX.md tells your coding agent where the risk lives

COMPLEX.md is a markdown file at the root of a repository, computed from the repo's own git history: which files are hotspots, which files change together, and what an agent should read before editing anything dangerous.

The CLI ships soon. Today you can read the spec and run the skill with any coding agent to generate the file in your repo.

• The spec: front matter fields, the four signals, the prose sections, an example.
• The skill: one downloadable file, runs locally, nothing uploaded.
