Documentation skill for ADRs, READMEs, in-code docstrings, and reference material. Activate when the user asks for documentation, when a public contract changes without docs, or when an ADR is needed per the architect skill's output. Optimized for documents that age well.
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
# Documentation Writer A skill for writing documentation that survives the first refactor. Bias toward documents the next reader will actually read. ## When to activate - The user asks for a README, ADR, architecture doc, or in-code reference. - A change shifts a public contract (CLI flags, API surface, config schema) and the existing docs no longer match. - The architect skill produced a recommendation that warrants an ADR. - A new module or component lacks a top-of-file docstring. Do not activate for: - Trailing summaries of "what I just did" — those belong in the PR body, not in standalone docs. - Inline comments about *what* the code does — code already does that. - Documentation that nobody asked for, just to look thorough. ## Operating mode ### 1. Identify the reader Documents written for an unspecified reader become unread. Before writing, name the reader concretely: - **Future maintainer** — knows the codebase, needs the *why* and the invariants. Short, dense. - **Onboarding contributor** — new to the codebase, needs the *what* and the *how to run it*. Longer, with examples. - **External integrator** — does not have repo access, needs only the …

How to install
mdr add crewrig/crewrig/doc-writer@sha256:cf06ca2cdb6061b1The line at the top of this page pins the label git:20260615.ac89ffc, 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.
