handoff

description	Move a slice from `in-progress` to `in-review` — verify Definition of Done, mark PR ready for review, update labels, append the work-log entry. Use when the implementation + tests are done and the PR is ready for another agent to review.

Skill: handoff

Transition one in-flight slice to review-ready. This is the opposite bookend to pick-slice — you took the slice, you did the work, now you're handing it off.

Rules this skill enforces

• Test Contract Closure Rule (see docs/Musubi/00-index/agent-guardrails.md#Test-Contract-Closure-Rule) — every bullet in every relevant spec's ## Test Contract section must be in one of three states at handoff: passing test with verbatim name / skipped with reason / declared-out-of-scope in the slice work log. This skill surfaces silent omissions; don't suppress them.
• Dual-update rule — handoff flips BOTH the GitHub Issue (status:in-progress → status:in-review) AND the vault slice file's frontmatter in the same PR. make issue-check catches any drift.
• No self-approval — handoff marks the PR ready for review; a different agent (or a human) approves + merges. If you push a commit in response to review, a different reviewer takes the next pass.

When to invoke

• User says: "hand it off", "this is ready for review", "close it out", /handoff.
• After you've pushed your final implementation commit for a slice and make check is green.

Do not invoke when

• Tests are still red.
• You haven't run make check end-to-end this session.
• You have uncommitted changes in the working tree.
• The slice's Definition of Done has unresolved boxes.

Instructions

1. Confirm the preconditions

# Working tree is clean
git status --porcelain
# Expect: empty output. If not, stop — commit or discard first.

# On the slice branch
git branch --show-current
# Expect: slice/<slice-id>

# Tests + lint + typecheck + coverage
make check
# Expect: all green. If not, stop — fix, don't hand off broken code.

If any check fails → do not proceed. Tell the user what's failing.

2. Re-read the Definition of Done

Open docs/Musubi/00-index/definition-of-done.md and the slice's own Definition-of-Done section. Verify each bullet — walk the list aloud in your reply so the user can see you checked:

• Every Test Contract item in the linked spec(s) is a passing test (or explicitly deferred with a named follow-up slice).
• Branch coverage ≥ 85 % on owned paths (90 % for planes/** / retrieve/**).
• Spec status: updated if prose changed (spec-update: trailer present in a commit).
• Work-log entry appended to the slice note.
• Imports honour the discipline from ADR 0015 (sdk only imports types; adapters only import sdk+types; api composes the rest).

If any bullet is not ticked → stop, ask the user whether to finish it or defer (with a reason).

3. Append the work-log entry

Edit docs/Musubi/_slices/<slice-id>.md under ## Work log:

### YYYY-MM-DD HH:MM — <agent-id> — handoff to in-review

- `<one-line summary of what landed>`.
- Tests: <n> passing (covers <m>/<total> Test Contract bullets; deferred: <list or "none">).
- Coverage: <pct> % on owned paths.
- `make check` clean: ruff format + lint + mypy strict + pytest.
- PR #<m> marked ready for review.

Commit as docs(slice): handoff <slice-id> to in-review.

4. Flip the slice frontmatter

• status: in-progress → status: in-review
• updated: <today>

Include this in the same commit as step 3 if you haven't pushed yet.

5. Append to the project work-log

If this slice realises a spec (most do), add an entry to docs/Musubi/00-index/work-log.md. Keep it short; the detail is in the slice note.

### YYYY-MM-DD — <slice-id> first cut ready for review

One paragraph on what landed and what it unblocks. Point at the slice note for detail.

Vault changes:
- [[_slices/<slice-id>]] — `status: in-progress → in-review`.
- <any spec files edited via `spec-update:` trailer>

Commit alongside step 3 or as a separate docs(work-log): <slice-id> ready for review commit.

6. Push + mark PR ready

git push
gh pr ready <m>
gh pr edit <m> --remove-label "status:in-progress" --add-label "status:in-review"
gh pr comment <m> --body "Ready for review. Recommending \`musubi-reviewer\` subagent for the first pass."

7. Remove the file-based lock

git rm docs/Musubi/_inbox/locks/<slice-id>.lock
git commit -m "chore(lock): release <slice-id> — handed off to in-review"
git push

Primary lock is now the status:in-review label + assignee on Issue #n.

8. Report

One or two lines back to the user: "<slice-id> handed off. PR #, slice status: in-review, Test Contract / covered, coverage %. musubi-reviewer can take it from here."

If review comes back with changes requested

• Flip slice back to status: in-progress.
• Re-add status:in-progress label to the PR.
• Address the review comments.
• Run through this skill again when ready.

Don't do

• Don't merge your own PR. A different human or agent approves + merges.
• Don't squash the branch history yourself. Review the PR's commit graph; squash-at-merge is the repo's merge strategy if that's what's configured.
• Don't silence failing tests. If a test is flaky, mark it @pytest.mark.flaky with a linked issue and explain in the review request — never just delete it.
