## What it does [#what-it-does]

Show the prompt library: templated prompts generated from the real capability surface (action kinds, detectors, skills), each bound to a real index query for this project — a prompt whose query returns nothing is withheld, not shown. Send one straight into the conversation.

## When to use it [#when-to-use-it]

**Use when:** "what prompts can I run" · "show me the prompt library" · "run the duplicate-code check prompt" · "send a prompt about this project"

**Also use when:** you want a starting point that names real files and counts instead of a generic instruction

## When not to use it [#when-not-to-use-it]

authoring a routine — use the author-routine skill; this library serves ready-made prompts, not new automation
