Check Completion

Two-phase audit-and-remediate skill. Phase 1 — Audit: scan task / session / plan / branch claims, classify every item into one of 22 statuses with cited evidence, deliver a markdown table. Phase 2 — Remediate: drive every in-scope row to a terminal status — Implemented for finished work, or a deliberate-stop terminal (Deferred to Human, Deprioritized, Cancelled, Out of Scope, Superseded with replacement verified, or Blocked — unresolvable with concrete next step). No mid-task pauses. No defaulting to Implemented on faith.

When to use

• "are we done?" / "what's left?" / "did we actually finish X?"
• verifying a claimed-done session, plan, branch, or PR before declaring complete
• producing a status report on a multi-step task with evidence per item
• catching silent gaps — tasks that were started, assumed complete, deferred, or forgotten
• recovering from a crashed / interrupted / half-finished execution by enumerating what remains
• converting a casual "I think we're good" into a rigorous completion audit
• triaging a TodoList where statuses drifted from reality

Do NOT use when:

• verifying a single claim before making it — use the Gate Function inline as a local verification gate, not the full audit
• evaluating reviewer comments, bot comments, or external review docs → evaluate-code-review
• planning upcoming work from GitHub issues → run-issue-tree
