+
+          WORKFLOW:
+            1. Setup (repo is pre-cloned at ~/coder)
+               cd ~/coder
+               git fetch origin pull/${PR_NUMBER}/head:pr-${PR_NUMBER}
+               git checkout pr-${PR_NUMBER}
+
+            2. Get PR info
+               Use GitHub MCP tools to get PR title, body, and diff
+               Or use: git diff main...pr-${PR_NUMBER}
+
+            3. Understand Changes
+               Read the diff and identify what changed
+               Ask: Is this user-facing? Does it change behavior? Is it a new feature?
+
+            4. Search for Related Docs
+               cat ~/coder/docs/manifest.json | jq '.routes[] | {title, path}' | head -50
+               grep -ri "relevant_term" ~/coder/docs/ --include="*.md"
+
+            5. Decide
+               NEEDS DOCS if: New feature, API change, CLI change, behavior change, user-visible
+               NO DOCS if: Internal refactor, test-only, already documented, non-user-facing, dependency updates
+               FIRST check: Did this PR already update docs? If yes and complete, say "No Changes Needed"
+
+            6. Comment on the PR using this format
+
+          COMMENT FORMAT:
+          ## 📚 Documentation Check
+
+          ### ✅ Updates Needed
+          - **[docs/path/file.md](github_link)** - Brief what needs changing
+
+          ### 📝 New Docs Needed
+          - **docs/suggested/location.md** - What should be documented
+
+          ### ✨ No Changes Needed
+          [Reason: Documents already updated in PR | Internal changes only | Test-only | No user-facing impact]
