# Prompt Library

> Use when looking for a ready-made agent or task template (code review, support, data analysis, translation, extraction) instead of writing one from scratch.

<objective>
Prompt Library is a collection of 18+ professional, tested prompt templates organized in three categories: general-purpose agents (code reviewer, support assistant, data analyst, technical writer, security auditor, API designer), task agents (summarizer, translator, extractor, classifier, generator, validator), and specialized-domain agents (legal, medical, financial, marketing, HR, educational). Each follows the standard Claude Code frontmatter (name, description, model, color, tools, skills).

It covers listing, searching, viewing, and using/customizing an existing template -- not designing a new agent architecture from scratch (see `agent-design` for that) or writing a prompt's internal structure (see `prompt-creation`).

- Rules and prohibitions (Forbidden)

## Contribution

To add an agent:

1. Create the `.md` file in the appropriate category (`agents/`, `tasks/`, `specialized/`)
2. Use the standard YAML frontmatter (name, description, model, color, tools, skills)
3. Test the agent with at least 3 use cases
4. Document output formats and rules (Forbidden)
