Every claim in\nthe result matches the code, and every visual renders cleanly.</p>\n<h2>Pick the mode</h2>\n<ul>\n<li><strong>Update</strong>: a code change made docs stale. Change the smallest set of docs.\nDone when each changed behavior is documented where its reader looks, and\nnothing unrelated changed.</li>\n<li><strong>Overhaul</strong>: the user asks to rewrite, restructure, or improve a doc set, for\nexample a README front page, guides, or an architecture doc. Done when:\n<ul>\n<li>each doc has one reader and one job, and each fact has one owner</li>\n<li>every claim matches the code, and every visual passes its render check</li>\n<li>the gate passes</li>\n</ul>\n</li>\n<li>A named doc or a named change is enough scope; start work. Ask only when the\nrequest names neither, with one question and these options: auto-detect from\nrecent changes, README, API docs, or the full doc set.</li>\n</ul>\n<h2>Readers</h2>\n<p>Decide the reader before writing.</p>\n<ul>\n<li><strong>Human</strong>: short, scannable text. Use a diagram, table, or chart when it\nanswers a question faster than prose. Load <code>references/doc-set.md</code> for doc\nroles and outlines, <code>references/style.md</code> for language, and\n<code>references/visuals.md</code> for diagrams and charts.</li>\n<li><strong>Agent</strong> (AGENTS.md, CLAUDE.md, skills, prompts): terse operational text with\nheaders, bullets, numbered steps, exact contracts, and a table where it is the\nclearest form. No diagrams or rationale that a model already knows. To score\nor lint instruction files, use <code>reviewing-instructions</code>.</li>\n<li><strong>Code</strong>: comments and docstrings state contracts, invariants, side effects,\nerrors, and non-obvious decisions. Delete comments that restate the code.\nLoad <code>references/code.md</code> for shared comment rules and per-language doc\nchecks.</li>\n</ul>\n<h2>Workflow</h2>\n<ol>\n<li>Scope the work from the request and the changed files (<code>git diff --name-only</code>),\nand find the existing docs that cover them.</li>\n<li>List the doc files, the reader and the job of each, and the facts that more\nthan one doc states. In Overhaul mode, write the ownership map from\n<code>references/doc-set.md</code> before editing.</li>\n<li>Read the code, tests, and configuration that each doc describes. When docs and\ncode conflict, report it and update the docs to the code, unless the user says\nthat the doc is the intended contract.</li>\n<li>Write. Keep each fact in one place and link to it from the others. Replace\nadjectives with measured facts.</li>\n<li>Check every claim against its source with <code>references/claims.md</code>. Generate\nsample output from the real code. Mark each claim that you cannot confirm,\nand say where you looked.</li>\n<li>Render every new or changed diagram and chart, look at the images, and fix\nthe faults named in <code>references/visuals.md</code>.</li>\n<li>Run the gate once. Run it again only after further edits.</li>\n<li>Report with the output contract.</li>\n</ol>\n<h2>Gate</h2>\n<p>Run the bundled scripts on the changed docs from the project root.\n<code>&lt;skill-dir&gt;</code> is the directory that contains this SKILL.md, as the host\nreports it. Do not use a <code>scripts/</code> directory of the project instead.</p>\n<pre><code>python3 &lt;skill-dir&gt;/scripts/check-links.py &lt;files or dirs&gt;   # relative links and #anchors\nbash &lt;skill-dir&gt;/scripts/render-mermaid.sh &lt;files or dirs&gt;   # renders each Mermaid block to PNG\npython3 &lt;skill-dir&gt;/scripts/prose-lint.py &lt;files or dirs&gt;    # advisory plain-language lint\n</code></pre>\n<ul>\n<li>Open the rendered images. A diagram that parses can still have a bad layout.</li>\n<li>Also run the repo's own docs checks, for example <code>markdownlint-cli2</code> or a\n<code>make</code> docs target, when they exist.</li>\n<li>Run documented commands and examples when practical.</li>\n</ul>\n<p>Done when the relevant build/test/lint checks pass on what you changed, or you\nname each check that did not run and why.</p>\n<h2>Rules</h2>\n<ul>\n<li>No speculative, future, or dead behavior.</li>\n<li>History (decision dates, \"agreed with\", replaced designs) belongs in git or\nthe changelog, not in design docs.</li>\n<li>No secrets, tokens, private paths, or internal hosts.</li>\n<li>Generated docs: edit the source and run the generator.</li>\n<li>No ADRs or <code>docs/adr/</code> changes unless explicitly requested.</li>\n<li>Do not commit, push, or publish unless the user asks.</li>\n</ul>\n<h2>Output</h2>\n<pre><code>## Documentation Update\n\nMode: update | overhaul\n\nUpdated:\n\n- `path` — &lt;what changed&gt; (reader: &lt;human | agent | code&gt;)\n\nMoved (overhaul only):\n\n- &lt;fact&gt; → owned by `path`; other docs now link to it\n\nChecked:\n\n- claims: &lt;n&gt; checked against source; unconfirmed: none | &lt;claim — where looked&gt;\n- visuals: &lt;n&gt; rendered and inspected | none changed\n- gate: links &lt;passed | failed&gt;, diagrams &lt;passed | skipped (reason)&gt;, prose &lt;n findings&gt;\n\nIssues: none | &lt;remaining issue&gt;\n</code></pre>\n<p>Without write access, return proposed changes (file, change, reason) instead of\napplying them.</p>\n<h2>Failure handling</h2>\n<ul>\n<li>No stale docs found: say so and list what you checked.</li>\n<li>Large audit: one bounded read-only helper can map docs against code.
