What does the Cache Prune skill do?
Reclaim disk on the shared JHT caches (`uv` wheel cache + `codex` SQLite log) every ~24h. Owned by the Dottore — single-instance, runs at the end of a routine round when the team is idle.

When should I use the Cache Prune skill?
Use Cache Prune when your Claude Code task falls under the Security category — specifically in the web security area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Cache Prune" or describe the task and let Claude pick). Browse related skills at /category/security/.
What is a Claude Code skill and how does the Cache Prune skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Cache Prune is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
