Refresh Documentation
This skill guides a systematic review and refresh of all documentation across the codebase. It is also invoked automatically each week by the refresh-documentation GitHub Actions workflow, which creates a GitHub issue assigned to Copilot.
When to Use This Skill
- When asked to "refresh documentation", "update docs", or "audit documentation"
- When documentation may be stale after significant code changes
- On the weekly scheduled cadence (triggered automatically via GitHub issue)
Scope
Documentation to review and update:
| Path | Description |
|---|---|
README.md | Root codebase README |
documentation/**/*.md | Core documentation files |
AGENTS.md | Workspace-level Copilot instructions — skill table must stay in sync |
*/AGENTS.md | Per-project Copilot instructions |
*/README.md | Project README files |
.github/skills/**/SKILL.md | Skill files (mirrored to documentation/skills/) |
Step-by-Step Workflow
Phase 1 — Audit
For each path in scope, read the documentation and cross-check it against the actual codebase. Classify every finding into one of three categories:
| Category | Criteria | Action |
|---|---|---|
| Deprecated | Documents a feature, command, file, or API that no longer exists | Remove the section or file |
| Outdated | Content exists but is inaccurate — wrong path, outdated command, incorrect description | Update to match current reality |
| Missing | A feature, project, convention, or workflow exists in the codebase but is undocumented | Create new documentation |
Phase 2 — Act
-
Remove deprecated content — Delete sections, files, or entries that document things that no longer exist. This includes dead links, removed commands, retired projects, and superseded conventions.
-
Update outdated content — Fix inaccurate content by cross-checking against actual source files:
- Code examples: verify commands, file paths, and APIs against the codebase
- README files: check that project structure, commands, and purpose are accurate
- AGENTS.md files: verify quick-reference commands still work and descriptions match current conventions
- Cross-references: fix broken internal links
-
Create missing documentation — Write new content for undocumented areas:
- New projects added since the last documentation refresh
- New conventions, tools, or workflows not yet documented
- Features documented in code comments but absent from markdown docs
