## Why Included

Lints CLAUDE.md / AGENTS.md / rules files for staleness, contradiction, and dead links.

## Source Summary

CLI that checks agent context files: flags stale dates, contradicting rules, dead links, and files over a token budget. CI-ready. Repo builds and tests pass.

## Practical Implication

Context files rot silently. Run ctxlint in CI so your agent instructions stay as maintained as your code.

## Agent-Ready Context

ctxlint lints agent context files (CLAUDE.md, AGENTS.md): staleness, contradictions, dead links, token budget. Add to CI beside your linter.
