description	Repository documentation management. Use this skill whenever you need to work on the codebase — before making changes, find relevant docs first; after making changes, index new knowledge back into docs.

repo-docs

Keeps the repository's documentation in sync with the codebase through two complementary workflows: Find Docs (read before acting) and Index Docs (write after acting).

Docs Structure

Documentation lives in docs/ at the repository root, split into four categories:

Folder	Purpose
concepts/	Domain concepts, mental models, and terminology
how-it-works/	Architecture, internals, data flow, and design decisions
how-tos/	Step-by-step guides for common tasks
conventions/	Coding standards, naming rules, and patterns to follow

Setup

Run the prepare script first. It creates any missing docs/ folders and ensures a documentation index exists at skills/repo-docs/state/index.md:

node skills/repo-docs/scripts/prepare.mjs

Find Docs

When: Before making any codebase change, answering architecture questions, or onboarding to an unfamiliar area.

Start from skills/repo-docs/state/index.md, then drill into the relevant category under docs/. See references/finding-docs.md for the full procedure.

Index Docs

When: After a change worth documenting — a new concept, pattern, architecture decision, or workflow.

Pick the matching category, prefer updating over duplicating, and update state/index.md to reflect the docs you changed. See references/indexing-docs.md for the full procedure and the doc template.
