Repo-Docs

Mission

repo-docs explains a repository to a human reader.

Do not start with a tree tour. Build a reader model first: what problem the repo solves, one real behavior it performs, the concepts behind that behavior, where those responsibilities live in code, where source truth lives, and how to verify the understanding.

Load Order

Read this file first.
Open REFERENCE.md for task routing when detailed rules are needed.
Open only the topic file the router points to.
Open EXAMPLES.md only for finished-page tone or output-shape examples.
Prefer bundled scripts over rewriting deterministic checks.

Keep the routing narrow. SKILL.md defines the contract; topic files carry the detailed rules. If a detail appears in two places, keep it in the topic file and leave a pointer here.

Document Contract

File	Role
`SKILL.md`	Entry: mission, core laws, output contract, mode router, finish gate
`REFERENCE.md`	Router to topic files; open only when detail is needed
`WRITING.md`	Explanation design, voice, evidence discovery
`PAGE_RULES.md`	Build workflow, reader paths, page types, output shape, navigation
`SCOPE_MODES.md`	Seed, large/monorepo scope, specialized repos
`SYNC_RULES.md`	Sync decision gate, question loop, change sync, widened content alignment
`ROOT_AGENT_RULES.md`	Root `AGENTS.md` / `CLAUDE.md` routing block and install contract
`QUALITY_RULES.md`	Evidence labels, source truth, quality bar
`EXAMPLES.md`	Finished-page tone and output-shape examples
`scripts/validate_repo_docs.py`	Structure, links, sync anchors, freshness, evidence, references scope, and quality-review checks
`validate_repo_docs.py`	Compatibility wrapper for older invocations
`evals/`	Source-repository regression fixtures and assertions for this skill; not required at runtime
`../repo-docs-zh/SKILL.md`	Chinese language overlay

Core Laws

Behavior before inventory: teach one real workflow, request, task, failure, or data path before describing the tree.
Code location after behavior: once the reader understands one real path, map every in-scope first-party source directory and the key files or symbols needed to locate changes without repeating module explanations.
