From the source SKILL.md

Pruner context is automatically injected into your conversation via a prompt-submit hook. You do NOT need to run pruner context manually — it has already run before you see the user's message.

What this skill does

Pruner is a community-contributed Claude Code skill in the code-quality sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/pruner/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Pruner Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 158,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
