docsync is a CLI tool that keeps documentation in sync with source code via SHA-256 checksums. Use this skill when: (1) setting up docsync.yml for a new project, (2) a docsync check error appears (out of sync / missing checksum / glob no matches), (3) deciding what sources to tie to what docs, (4) adding glob patterns to docsync.yml, (5) integrating docsync into CI or git hooks.
