claude-code-plugins

Use when you have an existing plan, design, or implemented code that needs adversarial review to find weaknesses, missing edge cases, and unnecessary complexity

Use when you want to autonomously improve a SKILL.md's quality by running iterative experiments. Triggers on "autoresearch 돌려줘", "스킬 품질 올려줘", "이 스킬을 자동으로 개선해줘", "run autoresearch on this skill", or any request to automatically improve a skill's eval pass rate through repeated experimentation. Applies Karpathy's autoresearch technique - fixed-budget iterative loop with single-metric hill-climbing and automatic keep/discard decisions.

Use when a developer needs to choose between two or more approaches during implementation. Triggers on "A vs B?", "should I use X or Y?", "which approach is better?", "Redis or Memcached?", "REST or gRPC?", "single table or split?", or any binary/multi-option technical decision. Use this skill whenever the user is weighing alternatives mid-implementation — even if they don't say "decide", if they're comparing approaches, this skill applies.

Use when creating implementation plans for complex multi-file features or architectural changes that benefit from multiple perspectives before implementation. Use this skill whenever the user asks to plan, design, or architect a feature that touches 3+ files, involves trade-offs between approaches, or would benefit from thinking through risks and requirements before coding. Even if the user says "plan this" without mentioning perspectives, this skill applies.

Google Gemini CLI fundamentals for code analysis, review, and validation. Use when (1) executing gemini commands for code review/analysis, (2) configuring models (gemini-3-flash-preview (default)/gemini-3.1-pro-preview (complex only)), output formats (text/json/stream-json), or sandbox modes, (3) managing Gemini sessions with /chat save/resume, (4) integrating Gemini into automation scripts and CI/CD pipelines. Do NOT use for orchestration patterns (use gemini-claude-loop instead).
