# Sunset Review > Use this skill when the user wants to identify unused, near-zero-use, or stale skills/agents/commands in the plugin surface so they can be demoted or retired. Combines agent-dispatch telemetry (start-events only) with static reference scanning, classifies every surface item into Active / Investigate / Demote / Retire, and emits a Markdown report plus JSON sidecar. NEVER auto-deletes — surfaces candidates for human decision. Quarterly cadence. Context: The plugin surface has grown and the maintainer wants to prune dead weight. user: "/sunset-review" assistant: "Running the sunset walk — classifying skills, agents, and commands by usage telemetry + static refs, grouped by Retire / Demote / Investigate / Active. No item is deleted automatically; I'll surface Retire/Demote candidates for your decision." The user wants a usage-driven prune candidate list; this skill runs the read-only walker, presents grouped verdicts, and writes a sidecar — it never deletes. - Skill: `kanevry/sunset-review` (Agent Skill) - Install (CLI): `npx skillmds@latest add kanevry/sunset-review` - Raw SKILL.md: https://api.skillmd.com/api/skills/kanevry/sunset-review/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: AI & ML - Author: Kanevry (https://skillmd.com/u/kanevry) - Updated: 2026-09-21 - Page: https://skillmd.com/skills/kanevry/sunset-review --- # sunset-review Canonical skill: `skills/sunset-review/SKILL.md` Read that file and follow it exactly.
