Transform user requests into detailed, precise prompts for AI models. Use when users say "promptify", "promptify this", or explicitly request prompt engineering or improvement of their request for better AI responses.

This skill should be used when users want to search, discover, install, or manage Claude Code skills from the CCPM registry. Triggers include requests like "find skills for PDF", "search for code review skills", "install cloudflare-troubleshooting", "list my installed skills", "what does skill-creator do", or any mention of finding/installing/managing Claude Code skills or plugins.

Ghost Security - SAST code scanner. Finds security vulnerabilities in source code by planning and executing targeted scans for issues like SQL injection, XSS, BOLA, BFLA, SSRF, and other OWASP categories. Supports applications (backend, frontend, mobile) and libraries (prototype pollution, unsafe deserialization, ReDoS, path traversal, zip slip). Use when the user asks for a code security audit, SAST scan, vulnerability scan of source code, or wants to find security flaws in a codebase or library.

Activates when the user asks about AI prompts, needs prompt templates, wants to search for prompts, or mentions prompts.chat. Use for discovering, retrieving, and improving prompts.

Comprehensive guide to stretchr/testify for Golang testing. Covers assert, require, mock, and suite packages in depth. Use when writing tests with testify, creating mocks, setting up test suites, or choosing between assert and require. Covers testify assertions, mock expectations, argument matchers, call verification, suite lifecycle, and advanced patterns like Eventually, JSONEq, and custom matchers. Apply when the codebase imports github.com/stretchr/testify.

Activates when the user asks about AI prompts, needs prompt templates, wants to search for prompts, or mentions prompts.chat. Use for discovering, retrieving, and improving prompts.

Given a documentation URL, crawl the docs and produce a fast-onboarding brief — mental model, the core 20% of the API, beginner gotchas, a runnable spike, and a cheat sheet. Use when the user pastes a docs link and wants to "get up to speed", "learn this fast", "onboard", "give me the 20%", or otherwise asks for a quick practical overview of a library, framework, API, or tool from its documentation.

Identifies and fixes Rails performance issues including N+1 queries, slow queries, and memory problems. Use when optimizing queries, fixing N+1 issues, improving response times, or when user mentions performance, slow, optimization, or Bullet gem.

Diagnose and prevent Kotlin plus Spring proxy failures around `@Transactional`, `@Cacheable`, `@Async`, method security, retry, configuration proxies, and JPA entity requirements. Use when AOP annotations appear to do nothing, transactional or cache behavior is inconsistent, compiler plugins may be missing, self-invocation is suspected, or Kotlin final-by-default semantics may break Spring behavior.

Test layering, execution, and CI guidance across unit, integration, and e2e. Use when designing tests, writing test cases, or planning test strategy for a module.
