Use when the user asks to install or maintain a documentation index, keep CLAUDE.md or AGENTS.md inventories synchronized with files, add document metadata, classify documentation, or apply documentation-only setup to a repository.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Project self-documentation

Keep instructions short: instruction file -> documentation index -> relevant document.
Use the deterministic scripts for discovery and validation; update explanatory prose
from the actual implementation and reviewed evidence.

## Locate resources and assess the project

Resolve this loaded SKILL.md's directory as `SKILL_DIR`. Its `scripts/` and
`references/` directories are self-contained siblings; do not search another
plugin's cache or assume a fixed user home, shell or install location.

Read the target project's applicable instructions first. Check Node.js is 18+
and inspect the existing documentation configuration, instruction markers and
hook arrangement. Choose explicit source roots and a documentation directory.
Source inventories read filenames only. Do not include sensitive/private data
paths or broaden an existing allowlist without reviewing its scope.

Read [metadata and lifecycle rules](references/metadata.md) when classifying or
creating documents, migrating a catalog, or resolving validation failures.

## Set up documentation only

Before the first installation, create `documentation.config.json` when a different
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add jrenaldi79/harness-engineering/documentation@sha256:81319dc90f3dfa18

The line at the top of this page pins the label git:20261018.e5b1d65, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
