Simplify and refactor code for clarity, consistency, and maintainability while preserving exact behavior. Use when code was just added or modified and needs readability-focused cleanup without changin…
AI-powered systematic codebase analysis. Combines mechanical structure extraction with Claude's semantic understanding to produce documentation that captures not just WHAT code does, but WHY it exists…
Use when implementing a feature, adding an endpoint, or making a non-trivial code change that requires pre-flight validation, TDD cycle, scope enforcement, and a clean commit. Combines pre-flight + td…
Quality control metrics and filtering thresholds for protein design. Use this skill when: (1) Evaluating design quality for binding, expression, or structure, (2) Setting filtering thresholds for pLDD…
Test-driven development for Spring Boot using JUnit 5, Mockito, MockMvc, Testcontainers, and JaCoCo. Use when adding features, fixing bugs, or refactoring.
Analyze git history for commit style, stage changes logically, and commit without pushing. Use when the user wants to commit changes matching their repository's existing style.
Provides Python patterns for type-first development with dataclasses, discriminated unions, NewType, and Protocol. Must use when reading or writing Python files.
Systematic debugging and error resolution using the TRACE framework (Trace, Read, Analyze, Check, Execute). Use when debugging errors, analyzing stack traces, investigating failures, root cause analys…
Review uncommitted Git changes for correctness, quality, and project convention alignment, then apply fixes and prepare a safe, atomic commit plan. Use when users ask to review code before committing,…
Use when auditing API routes for schema drift, missing auth, or validation gaps. Scans routes against shared TypeScript types to find mismatches, missing middleware, and undocumented endpoints. Read-o…
Use when deciding whether to extract Terraform code into a reusable module, determining module boundaries, or migrating state after modularization. Covers the refactoring decision (modularize vs inlin…
Run and create evals for testing agent behavior. Use when the user wants to create or run an eval.
ActiveRecord model patterns and conventions for Rails. Automatically invoked when working with models, associations, validations, scopes, callbacks, or database schema design. Triggers on "model", "Ac…
Use when drafting a Conventional Commit message from currently staged Git changes. Triggers: 'write commit message', 'draft commit from staged changes', 'generate conventional commit', 'message for gi…
Provides Zig patterns for type-first development with tagged unions, explicit error sets, comptime validation, and memory management. Must use when reading or writing Zig files.
Automatically activated when user asks about test quality, code coverage, test reliability, test maintainability, or wants to analyze their test suite. Provides framework-agnostic test quality analysi…
Quizzes the developer on code, architecture, or plans that an AI agent just built or proposed — one question at a time, with ASCII diagram corrections. Use after any significant implementation, PR, re…
Use when given a bug report, failing test, stack trace, or CI failure that needs diagnosis and repair. Autonomously diagnoses root cause, implements minimal fix, verifies correctness, and commits. Key…
Use when committing code changes. Runs lint, typecheck, Semgrep security scan, optional CodeRabbit review, and related tests before creating a quality-gated commit. Flags: --review, --push, --dry-run,…
PostgreSQL database patterns for query optimization, schema design, indexing, and security. Based on Supabase best practices.
Automatically invoked when analyzing code quality, refactoring, or maintainability. Triggers on mentions of "code smell", "refactor", "code quality", "technical debt", "complexity", "maintainability",…
Systematically eliminate configuration bugs by testing 8-10 fundamentally different solutions in parallel. When root cause is ambiguous, this methodology finds the fix in hours instead of days through…
Advanced coverage analysis with actionable insights. Use to identify coverage gaps, suggest specific tests, track coverage trends, and highlight critical uncovered code. Essential for reaching 80%+ co…
Document software architecture using ARCHITECTURE.md and docs/*.md files with Mermaid diagrams. Use proactively when ARCHITECTURE.md exists in project root, or invoke to create initial architecture do…
