name	spec-check
description	Run the Musubi vault hygiene gates — frontmatter, slice DAG, Test Contract presence, broken wikilinks, stale status. Use before opening a PR that touches `docs/Musubi/` or as a quick health check of the vault.

Skill: spec-check

Run every vault-hygiene check Musubi ships and produce a one-screen report. Designed to be fast (< 15 s on the current vault) and to be runnable from any agent (not Claude Code specific).

When to invoke

• Before opening a PR that touches docs/Musubi/.
• When the user says: "check the vault", "anything stale?", /spec-check.
• After pulling an upstream change that touched specs, to sanity-check your working copy.
• Before handoff, to generate the Test Contract coverage matrix that the PR template requires. Run make tc-coverage SLICE=<slice-id> and paste the output into the PR description. Anything marked ✗ missing blocks merge — either write the test, add @pytest.mark.skip(reason=...), or declare out-of-scope in the slice's work log, then re-run.

Do not invoke when

• The user asked for a code-only check → use make check instead.
• You're mid-edit and the tree isn't in a reviewable state.

Instructions

1. Run the vault-state gates

cd ~/Projects/musubi  # or wherever the repo is
make agent-check

agent-check covers:

• Frontmatter schema (every note has title, section, type, status, tags, updated).
• Slice DAG (no cycles, every depends-on resolves to a real slice file, blocks: is the inverse of depends-on across the set).
• owns_paths / forbidden_paths do not conflict across slices (two slices can't claim the same path).
• Every slice-*.md has a Definition-of-Done section and a Work-log section.
• Every _slices/slice-<id>.md has a matching status: value (ready | in-progress | in-review | blocked | done).

If make agent-check fails, stop — the PR that introduces vault state violating the gates is not mergeable.

2. Check for stale status

Print to stdout (agent-readable) in a table:

echo "=== slice status counts ==="
for s in in-progress in-review blocked ready done; do
  n=$(grep -l "^status: $s" docs/Musubi/_slices/slice-*.md 2>/dev/null | wc -l | tr -d ' ')
  printf "  %-12s %s\n" "$s" "$n"
done

Flag anything surprising:

• in-progress slices with no commit on any slice/<id> branch in the last 7 days → likely abandoned; suggest the user run pick-slice to re-home them or mark blocked.
• in-review slices with a PR that's been open > 7 days → suggest nudge.
• blocked slices: list them with the cross-slice ticket file they reference, so the user can check if the blocker is resolved.

3. Lock file sanity

ls docs/Musubi/_inbox/locks/ 2>/dev/null

Every lock file must map to:

• An in-progress slice with matching frontmatter, and
• An open GitHub Issue with status:in-progress label.

Orphan locks (file exists, no matching Issue or frontmatter) → suggest git rm — they're stale.

4. Wikilink health (lightweight)

Walk every .md file in docs/Musubi/ and grep for [[...]] references. For each, check:

• Target file exists (allow optional #section suffix).
• Anchor resolves to a heading (skip if target has no .md).

Output just the broken ones. Do NOT auto-fix — the user reviews the list and decides.

python3 - <<'PY'
import pathlib, re, sys
root = pathlib.Path("docs/Musubi")
pattern = re.compile(r"\[\[([^\]|#]+)")
errors = []
md_files = {p.relative_to(root).with_suffix("") for p in root.rglob("*.md")}
for md in root.rglob("*.md"):
    for m in pattern.finditer(md.read_text(errors="ignore")):
        target = pathlib.PurePosixPath(m.group(1))
        if target not in md_files and target.with_suffix("") not in md_files:
            errors.append((md.relative_to(root), str(target)))
for src, tgt in errors[:40]:
    print(f"  {src}: [[{tgt}]]")
print(f"total broken wikilinks: {len(errors)}")
PY

5. Print the verdict

SPEC-CHECK REPORT  (YYYY-MM-DD HH:MM)

  slices: {in-progress: n, in-review: m, blocked: k, ready: r, done: d}
  locks: {active: a, orphan: 0}
  broken wikilinks: 0
  stale in-progress (>7d no commit): 0
  stale in-review (>7d no review): 0

  make agent-check: PASS

All clear to open/merge PRs touching the vault.

If anything is non-zero, list the specific items, not a summary count.

Output contract

This skill prints to stdout in plain text. It does not modify any files. Other agents pipe this report into PR bodies or paste it into issue comments.

If you find real problems

• Report them. Do not fix them as part of this skill.
• Suggest the right next skill or agent (pick-slice to re-home a stale slice, musubi-spec-author to revise a broken ADR, etc.).
