thinking-sequentially

Toyota-style A3 problem solving with embedded priority hierarchy: Safety First, then Customer Value, then Shareholder Value. Structured thinking framework for manufacturing decisions, root cause analysis, and countermeasure development. USE WHEN user says 'A3', 'problem solving', 'root cause', 'countermeasure', '5 whys', 'fishbone', 'ishikawa', 'priority decision', 'safety first', 'critical thinking', or needs structured analysis of manufacturing problems. Integrates with AutomotiveManufacturing and HoshinKanri skills.

Use this skill for systematic problem-solving through structured, iterative thinking. Break down complex problems, iterate on understanding, catch edge cases, and validate solutions comprehensively.

[Planning] Apply structured, reflective problem-solving for complex tasks requiring multi-step analysis, revision capability, and hypothesis verification. Use for complex problem decomposition, adaptive planning, analysis needing course correction, problems with unclear scope, multi-step solutions, and hypothesis-driven work.

Automates the complete Blender build-go workflow, from building and packaging your extension/add-on to removing old versions, installing, enabling, and launching Blender for quick testing and iteration.

Backend patterns for ORPC routers, Drizzle schemas, and server-side code. Use when creating API endpoints, database tables, or services.

Authentication middleware for Express.js and Node.js applications. Use when building Express APIs that need JWT authentication, OAuth, or custom auth strategies. Provides 500+ authentication strategies. Choose Passport.js over Auth.js for Express backends, pure API servers, or when you need maximum control over auth flow.

Node.js/TypeScript backend expert. Handles Express/Fastify API routes, TypeScript strict mode, Prisma ORM, Zod validation, error handling, configuration management. Use when project is Node.js backend (package.json + TypeScript server).

专注于 Node.js 后端开发模式与最佳实践。

Create and manage database schema migrations with reversible operations, zero-downtime deployments, and safe rollback strategies. Use this skill when writing database migrations for PostgreSQL, MySQL, SQLite, MongoDB, or any database system; when using ORMs like Prisma, Sequelize, TypeORM, ActiveRecord, Django ORM, or similar migration tools; when implementing schema changes (adding tables, columns, indexes, constraints); when performing data migrations or transformations; when creating indexes on large tables with concurrent options to avoid locks; when separating schema changes from data migrations for safer rollbacks; when implementing zero-downtime deployment strategies for high-availability systems; when versioning database schemas and managing migration order; or when working with database change management in production environments.

Skill para diseñar y construir backends y APIs **modulares**, **auditables**, **resilientes** y **multi-tenant**, con seguridad fuerte, modelado correcto (incl. ledger cuando aplique), datos y jobs/colas operables.
