Explorar skills

Implement structured logging and analyze logs to diagnose issues. Use when the user sets up logging, asks about log levels, needs to trace requests through distributed systems, or is analyzing log output to debug a problem. Apply when adding logging to any application.

Guide file and directory organization for maintainable codebases. Use when the user creates new files, asks where to put code, plans project structure, or when a file exceeds 400 lines. Apply when scaffolding new projects or refactoring large files into smaller modules.

Patterns for when and how to use Claude Code subagents via the Agent tool. Use when the user needs to delegate research, run parallel investigations, protect the main context window, or asks about subagent types like Explore or Plan.

Guide for deployment strategies including blue-green, canary, rolling updates, feature flags, and rollback procedures. Use when the user asks about deployment patterns, zero-downtime deployments, release strategies, or rollback plans. Trigger whenever deployment, release management, or production rollout is discussed.

Implement FastAPI dependency injection with Depends(), security dependencies, database session management, request-scoped deps, and testing with overrides. Use when the user builds FastAPI endpoints, manages database connections, implements auth, or asks about dependency injection. Trigger when you see repeated setup logic in endpoint functions that should be extracted to dependencies.

Write clean, idiomatic Go following community conventions and effective patterns. Use when the user writes Go code, designs packages, defines interfaces, uses struct embedding, writes receiver methods, organizes Go projects, or asks about Go best practices and conventions.

Master Rust's ownership, borrowing, and lifetime system for memory-safe code. Use when the user encounters borrow checker errors, lifetime annotations, needs smart pointers (Box/Rc/Arc), works with move semantics, or asks about Clone vs Copy, ownership transfer, and reference management in Rust.

Validate and sanitize all user input using schema validation libraries. Activate whenever the user writes form handlers, API endpoints, request parsers, data processing functions, or any code that accepts external input. Also activate when the user asks about validation libraries like Zod, Joi, or Pydantic, or discusses input sanitization.

Guide for configuring PreToolUse, PostToolUse, and Stop hooks in Claude Code. Use when the user asks about hooks, wants to run commands before/after tool calls, needs auto-formatting, auto-linting, validation gates, or mentions settings.json hook config.

Patterns for learning from corrections, capturing instincts, extracting stable patterns, and building cross-session knowledge. Use when the user corrects you, when you discover a recurring pattern, or when insights should persist beyond the current session.

Implement effective caching at every layer: in-memory, Redis, CDN, and browser. Activate whenever the user asks about caching, performance optimization for repeated data access, Redis patterns, CDN configuration, cache invalidation, HTTP cache headers, memoization, or stale-while-revalidate strategies.

Set up automated code quality tools: ESLint, Prettier, pre-commit hooks, and CI linting. Activate whenever the user sets up a new project, asks about code formatting, configures linters, sets up Git hooks, or mentions Husky, lint-staged, CODEOWNERS, or pre-commit hooks. Also activate when discussing consistent code style enforcement.
