Use when the user asks to humanize a MIDI part, fix voice leading, quantize notes, clean up timing, fix stuck/duplicate notes, or generally polish a MIDI clip they recorded or wrote. Examples - "humanize this hat", "voice these chords better", "the timing is too stiff", "fix the voice leading on the strings".

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Research-grounded 5-principle behavioral contract for production LLM coding agents — Think Before Coding, Simplicity First, Surgical Changes, Goal-Driven Execution, and Calibrated Communication. Each principle names its anti-patterns and failure modes with empirical backing (SWE-bench, FeatBench, DELEGATE-52, SE literature). Apply when implementing features, fixing bugs, refactoring, or any coding

TypeScript development — use when the user works with TypeScript, type system patterns, generics, Zod, tsconfig, NestJS, branded types, or runtime validation. Covers type system mastery, framework integration, architecture patterns, security, and testing strategies. NOT for Python development (use python-development), NOT for React component patterns or hooks (use react-development), NOT for Next.

Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.

Generates OpenAPI-compatible documentation for REST API endpoints from code or route definitions.

Runs a systematic checklist review on any code diff or file, covering correctness, security, performance, and readability.

Use this skill whenever the user asks you to help write, draft, or generate academic, technical, or professional text that should sound human-written rather than overly synthetic. Trigger when the user says things like "write this for me but make it sound human", "help me draft X without synthetic writing patterns", "write like a student", or any time the user wants a natural, informal, or imperfe

Use when the goal is to reduce code size, remove unnecessary complexity, or simplify a module without removing user-facing behavior.

Capture each prompt into Graphiti memory (episodes) for this repo/user.

Acione quando o usuário solicitar trabalho de implementação, exploração de repositório, inspeção de dados/logs, busca na base de código, análise de impacto, trabalho de shell com muita verificação, ou mencionar explicitamente 'Codex'. Também acione para subtarefas internas pesadas que o Claude Code normalmente delegaria a um modelo leve/Haiku.

Communicate systems and flows visually using Mermaid (flowchart, sequence, state, ER, class), the C4 model, and diagram-as-code. Use when the user asks to draw a flow, sequence diagram, state machine, ER diagram, C4 model, architecture diagram, or wants Mermaid code for a system, wants to pick a diagram type, or wants to visualize a process as a flowchart. NOT for UI/UX mockups or visual design (u
