Use when creating Product Requirements Documents. Enforces clarification-first workflow, junior-dev-friendly language, and standard PRD structure. Triggers: 'create PRD', 'write requirements', 'product requirem...
Use when writing or improving any LLM prompts. Applies TDD methodology and research-backed practices (Meincke 2025): test don't assume, measure baseline, iterate rigorously. Prevents assuming universal techniqu...
Use when implementing automated tests. Enforces empirical testing, test pyramid, TDD practices, concurrent testing. Triggers: writing tests, test planning, implementing test cases, TDD, race conditions.
Use when writing documentation, commit messages, error text, explanations, reports, or summaries. Applies Strunk's principles for clear, vigorous prose. Triggers: writing human-readable content, verbose text, u...
Use when reviewing code for production readiness. Identifies critical issues causing production failures: data loss, security breaches, race conditions, performance degradation. Focuses on measurable impact, no...
Use when replacing approaches or dismissing patterns. Traces decision history through git/jj logs, commit messages, and decision records to avoid repeating failures and rediscover abandoned solutions. Triggers:...
Required for any bug, error, test failure, or unexpected behavior. Enforces root cause investigation before fixes through 4-phase framework. Prevents random fix attempts and ensures evidence-based debugging. Au...
MUST use before any commit operation. Detects VCS type (prefers jujutsu over git), enforces atomic commits, validates messages, runs tests. Required before: 'git commit', 'jj commit', 'commit these changes', 'l...
Use when implementing code changes. Enforces production-grade principles: pragmatism, domain awareness, clarity, performance, correctness. Triggers: implementing features/fixes, refactoring, writing new code, b...
Required when creating SKILL.md files for Claude Code agents. Specializes prompt-engineering TDD with agent-specific requirements: frontmatter format, persuasion principles, 500-line limit, progressive disclosu...
Use when claiming work is complete, tests pass, or fixes work. Required before commits and PRs. Enforces running verification commands and confirming output before success claims. Triggers: 'done', 'fixed', 'pa...
Use when implementing visual design, styling components, or building design systems. Enforces intentional aesthetics, systematic design tokens, production-grade implementation. Triggers: 'implement design', 'st...
Use when designing user interfaces, improving UX, or creating design specifications. Enforces user-centered process, WCAG 2.1 AA accessibility, mobile-first approach. Triggers: 'design interface', 'improve UX',...
