variant-analysis

Find similar vulnerabilities and bugs across codebases using pattern-based analysis. Use when hunting bug variants, building CodeQL/Semgrep queries, or performing systematic code audits.

oh-my-claude

Activates Prometheus planning mode for structured requirement gathering, codebase research, and task planning within Claude Code.

ultraqa

Autonomous QA cycling workflow that runs test-verify-fix loops until your quality goals are met.

ai-llm-patterns

Anthropic Claude integration patterns: streaming, RAG with pgvector, tool use, model selection (Haiku/Sonnet/Opus), prompt caching, and cost management for AI-powered engineering.

mutation-test

Run mutation testing to measure test suite effectiveness by introducing code faults and verifying test failure detection.

mutation-testing-js

Mutation testing patterns for JS/TS using Stryker. Analyze branch code to find weak or missing tests, verify test effectiveness, and strengthen Node.js test suites.

test-skill

A testing fixture for validating AI agent skill configurations and detecting rule violations.

testability-scoring
