Desenvolvimento

Use when starting feature work that needs isolation from current workspace or before executing implementation plans - creates isolated git worktrees with smart directory selection and safety verification

Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies

Execute JXA scripts scoped to a macOS application. Use when running JXA expressions or script files against an app via osascript. Validates Application() scope via AST.

Consult Claude specialist agents during implementation for codebase understanding, pattern checking, security review, debugging help, and more. Use this skill whenever you're unsure about conventions, stuck on a failure, or need expert input before writing code. Does not replace the formal review gates in agent-loops — this is for mid-implementation consultation.

Use when writing production code that needs tests - new features, bug fixes, refactoring. Enforces RED-GREEN-REFACTOR cycle before any implementation.

Workflow navigation assistant. Scans project state (plans, reviews, tests, git) and recommends the next step in the 7-phase pipeline. Use when asked "what should I do next?", "where am I?", "help", or at session start. NOT for domain complexity routing (see mk:scale-routing); NOT for skill discovery (descriptions handle that automatically).

Generates Javadoc comments for Java classes and methods. Use when user asks to "add javadoc", "document this class", "write documentation", "add comments", "generate docs", or "document this method".

Create and validate Mermaid diagrams. Use when creating, editing, or reviewing Mermaid diagrams in markdown files.

Reviews or implements Clean Architecture / Hexagonal Architecture (Ports & Adapters) and DDD tactical patterns for Java projects. Use when user asks to "apply clean architecture", "implement hexagonal architecture", "add ports and adapters", "apply DDD", "refactor to clean arch", "review architecture", or "add value objects".

Validação da qualidade do código com linters, princípios SOLID, detecção DRY, detecção de erros e conformidade arquitetural em todas as linguagens.

Fetch, reply to, and resolve review threads on a GitHub pull request. Use when checking what review feedback needs addressing, whether threads are resolved, replying to review comments, or clearing AI-reviewer threads after acting on them.

Use when writing TypeScript code, fixing type errors, or configuring strict type safety. Auto-activates on .ts/.tsx files. Covers null handling, utility types, and ESLint.
