description: Use only when a developer explicitly asks to clean, prune, tidy, or organize DeepChat SDD documentation after implementation and validation. Scans docs/features, docs/issues, and docs/architecture; prefers multi-agent review when available; removes completed issue docs when a linked GitHub issue is closed or implementation and validation evidence proves the bug no longer exists, drops stale plans and legacy task files from completed feature or architecture goals, and deletes obsolete feature or architecture docs.

# DeepChat SDD Cleanup

## Rule

Run this skill only when the developer explicitly asks for SDD cleanup, documentation tidying, pruning,
or removal of completed/stale SDD files. Do not run it as an automatic final step of ordinary
feature, bug, architecture, or release work.

## Workflow

1. Inspect `docs/spec-driven-dev.md`, `docs/README.md`, and `git status`.
2. Inventory `docs/features`, `docs/issues`, and `docs/architecture` with `find` or `rg`.
3. Prefer parallel sub-agent review when available:
   - one pass for `docs/features`
   - one pass for `docs/issues`
   - one pass for `docs/architecture`
   - optional verifier pass over proposed deletes
4. Apply only changes with clear evidence. Keep a concise keep/delete/update list for handoff.
5. Validate references after edits.

## Cleanup Rules

- Completed feature or architecture goal: delete `plan.md` and any legacy `tasks.md`; keep `spec.md`
  only when it still defines a maintained contract, regression guard, platform policy, or
  architecture decision.
- Completed issue goal: delete the issue folder when a linked GitHub issue is closed or the
  implementation and validation evidence prove the bug no longer exists.
- Removed feature: delete its folder when the product/code path is gone and the spec has no reusable
  decision record.
- Obsolete architecture: delete its folder when the module was fully replaced and the doc no longer
  describes a maintained boundary; otherwise update the spec.
- Historical feature spec affected by an architecture refactor: update the retained spec instead of
  leaving contradictory docs.

## GitHub Checks

Use `gh` only when it is installed and authenticated. For linked issue docs, verify closure with
`gh issue view <number> --json state,url,title` when possible. If `gh` is unavailable, do not delete
solely because a GitHub link looks old.

## Never Delete

- Active work with unchecked `plan.md` steps or legacy tasks.
- Any document containing unresolved `[NEEDS CLARIFICATION]`.
- A document referenced by `docs/README.md`, `docs/ARCHITECTURE.md`, `docs/FLOWS.md`, or AGENTS
  instructions unless the reference is updated in the same change.
- Runtime baselines or machine-read files unless the cleanup request explicitly covers them.

## Validation

- Run `rg -n "plan.md|tasks.md|docs/archives|NEEDS CLARIFICATION" docs AGENTS.md .agents/skills`
  and inspect any stale policy references.
- Run `git status --short`.
- For Markdown-only cleanup, formatting/lint commands are optional unless repository instructions or
  touched generated files require them.
