What problem does it solve? After merges, issue trackers accumulate stale open issues that were actually fixed by merged PRs, forcing teams to manually reconcile PRs against issues before every release. This Skill automates that reconciliation by scanning recent pull requests and closing only the issues with authoritative fix links. ## Core Features & Use Cases - Authoritative close detection: Uses the tracker's closingIssuesReferences plus configurable close keywords (fixes/closes/resolves and custom non-English keywords), never acting on bare #N mentions. - Safe claim-and-release locking: Claims each issue with an assignee, in-progress label, and claim comment before closing, and always releases the lock even on error. - Dry-run and gap reporting: --dry-run previews every planned mutation, and unmatched issue mentions are surfaced so teams can extend closeKeywords. - Use Case: Before tagging a release, run the skill with --since last-release to close every issue fixed by PRs merged into the base branch and comment on issues whose PRs were closed unmerged or merged into a non-base branch. ## Quick Start Ask the agent to run ot-close-fixed-issues with --dry-run to preview which tracker issues the recently merged PRs would close.
