What problem does it solve? Stale issue trackers and backlogs accumulate items that are already implemented, duplicated, or no longer needed, and manually verifying each one against the current codebase is slow and error-prone. This Skill drains that queue by establishing the current truth for every item against live code, with an independent verifier gating every automatic close. ## Core Features & Use Cases - Read-only parallel triage: Dedups and classifies each issue and backlog item across four dimensions β code on the staging branch, active worktrees, open PRs, and .planning plan folders β without mutating anything. - Evidence-gated auto-close: An item closes only when classified already-done or solved-differently with a concrete artifact reference (commit SHA, merged PR, plan id, or file:line) confirmed by an independent adversarial verifier. - Serial apply with ledger events: Applies GitHub issue closes and append-only events to .planning/events.jsonl one at a time, then writes a sweep ledger summarizing every verdict. - Use Case: A repository has 60 open issues and 30 backlog items accumulated over months. Run the sweep to close the 20 already shipped, collapse duplicates, label the genuinely open work as fix-ready, and hand that set to a fix loop. ## Quick Start Ask the agent to run a triage sweep over all open GitHub issues and the .planning backlog to close items already implemented on the staging branch.
