Explorar skills

Discover available agents, skills, quality commands (lint, test, typecheck), tech stack, verification capabilities, and LSP code intelligence features via parallel environment scanning. Use when starting implementation, creating PRs, reviewing PRs, or addressing feedback. This skill MUST be consulted because assuming tools exist causes runtime failures, and assuming they do not causes missing capa

Survival analysis methods including weighted logrank, MaxCombo, RMST, and milestone tests. Use when analyzing TTE data or choosing analysis methods for non-proportional hazards.

Analyzes test coverage, identifies untested code paths, and generates tests for the most critical uncovered areas. Use to improve test coverage before releases.

Implements a persistence layer using SwiftData or CoreData following MVVM — models, repository abstraction, and testable in-memory setup. Use when user says "add CoreData", "set up SwiftData", "persist data", "save to database", "add a data model", "create Core Data entities", or "use SwiftData models".

Maestro E2E testing knowledge for Flutter apps. YAML-based flows, TestKeys, visual regression, Maestro MCP integration. Background knowledge for QE E2E testing phase.

Use when starting feature work that needs workspace isolation — creates git worktree with automatic project setup and baseline test verification. Ensures worktree directory is git-ignored and safe. Integrates with code-forge:impl and code-forge:finish.

Systematic 5-step backend debugging flow for AI-coded FastAPI apps. Load this skill when a bug is reported, a test fails, or unexpected behavior appears in any backend layer. Forces layer isolation before touching code — prevents the "touch 8 files and make it worse" pattern.

A única habilidade necessária para construir e entregar software de classe mundial, da ideia à produção. Abrange o ciclo de vida completo, incluindo arquitetura, design, implementação com TDD, frontend distinto, QA, segurança, escalabilidade, confiabilidade e otimização de desempenho.

Generates a CI/CD pipeline configuration for the project. Auto-detects the stack and creates GitHub Actions, GitLab CI, or other CI configs with lint, test, build, and deploy stages.

Use for iOS/macOS concurrency problems involving dispatch queues, locks, or thread safety. Triggers on: deadlocks (sync on main, nested sync, ABBA lock ordering), thread explosion from too many DispatchQueue.global() calls, data races flagged by Thread Sanitizer (TSan), DispatchGroup enter/leave imbalance, DispatchSource timer leaks, lock selection (NSLock vs OSAllocatedUnfairLock vs os_unfair_loc

Writes unit tests and UI tests for Swift, SwiftUI, and UIKit projects following enterprise or indie testing standards. Use when user says "write tests", "add unit tests", "test this code", "create test cases", "add XCTest", "write Swift Testing tests", "help me test this", or "add tests for". Applies enterprise or indie standard from references/ based on project CLAUDE.md config.

Detect, classify (porcelain status; complexity: trivial, semantic, structural, delete-modify), and resolve git merge conflicts through per-file strategy selection (accept-ours, accept-theirs, manual-merge, rebase), manual conflict hunk parsing, and post-resolution verification (orphaned markers, build, tests). Use when a branch has conflicts with its merge target or when rebasing onto an updated b
