If any commit message contains `[skip-docs]`, stop and report NO_DOC_UPDATE_NEEDED.\n\n2. Run `git diff HEAD~1 --stat` to get the list of changed files, then `git diff HEAD~1` to get the full diff. If the diff is larger than 500 lines, report NEEDS_HUMAN_REVIEW with a summary of which areas likely need docs.\n\n3. Read `.kiro/agents/doc-updater.md` for the full decision tree and `.kiro/steering/doc-standards.md` for formatting conventions.\n\n4. Follow the doc-updater decision tree: triage the change, decide if docs need updating, survey existing docs (README.md, docs/ folder), and propose surgical edits.\n\n5. For any proposed changes, apply them directly to the doc files. Only touch README.md and files under docs/. Never touch code files.\n\n6. After applying changes, output the SUMMARY block from the decision tree so Jordan can review what was changed and why."
