Wrap (session exit check)

Answer "good to exit?" with evidence, not a question back. Sweep, give a
verdict, offer one-shot fixes for anything left.

Checks (read-only)

Run in parallel where possible, covering every repo/worktree touched this
session:

1. Working tree — git status --short --branch --untracked-files=all.
   Dirty files? Untracked files created this session? For whitelist-ignored
   dirs (e.g. claude/skills/.gitignore), run git check-ignore on files
   created this session — silently-ignored new files are a known trap.
2. Unpushed work — ahead-of-upstream count on every branch touched this
   session.
3. Leftovers — stale worktrees (git worktree list), /tmp/coreview-*
   dirs/logs, scratch refs (refs/coreview/*).
4. Background work — shells, tasks, or agents started this session that
   are still running.
5. Session promises — follow-ups stated in conversation but not done
   (deferred findings, "later", "next time"). Anything real gets filed per
   tracking rules (Jira for work, repo todos otherwise) — not left implicit.

Verdict

• All clean: "Good to exit." plus one line of state (branch == origin,
  tree clean). Stop there — no questions.
• Items found: numbered list with a fix plan. Ask once, "fix all" default.
  Apply, re-verify, then give the verdict.

Notes

• Read-only until fixes are approved — pushing is a fix, not a check.
• Keep the clean-path output under 5 lines. This skill exists to remove the
  "anything else?" round-trip, not add one.
• Scoped to the session, not the world: do not audit unrelated repos or
  long-standing drift (that's reconcile).
