Use when implementing any feature or bugfix, before writing implementation code

Interpretabilidade e explicabilidade de modelos usando SHAP (SHapley Additive exPlanations). Use esta skill para explicar previsões de modelos de machine learning, calcular a importância de features, gerar gráficos SHAP, depurar modelos, analisar viés ou justiça, comparar modelos e implementar IA explicável. É compatível com modelos baseados em árvores.

Pre-build decision intelligence. Produces opinionated decision brief — the senior- consultant week-1 output before scope, stack, or approach are locked. Surfaces traps and edges, calibrated to project scope (prototype vs production vs enterprise). Use when user says '/recon', 'what to watch out for building X', 'where's the edge', 'common mistakes with X', starts a new project, or hits domain unce

This skill should be used when writing tests, validating features, or needing to verify code works. Triggers on "write tests", "add test coverage", "validate feature", "integration test", "end-to-end", "e2e test", "mock", "unit test". Enforces scenario-driven testing with real dependencies in .scratch/ directory.

GitHub Issue 处理协作流程。当用户收到 issue 需要分析和回复时使用。通过"诊断 → 定性 → 决策 → 回复"四步法，从一个 issue 产出准确的根因分析和得体的用户回复，避免误判问题类型或回复不专业。

Use when the user asks to update, prune, audit, or create AGENTS.md, CLAUDE.md, or other agent context files. Also use when the user says their AI agents keep making the same mistakes and they want to fix it at the context level.

Spec-Driven Development (SDD) methodology based on GitHub's SpecKit.

Maintain consistent code formatting, naming conventions, type safety, and automated code quality standards across PHP and TypeScript/JavaScript. Use this skill when writing or editing any PHP files (.php), TypeScript/JavaScript files (.ts, .tsx, .js, .jsx), when implementing type declarations and return types, when running code formatters (Laravel Pint, Ultracite) or linters, when running static a

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.

Automatically activated when user works with Playwright tests, mentions Playwright configuration, asks about selectors/locators/page objects, or has files matching *.spec.ts in e2e or tests directories. Provides Playwright-specific expertise for E2E and integration testing.
