Kaizen

This is a thoughtful approach to code quality that emphasizes iterative refinement over big bang rewrites. It guides you to make three passes (make it work, make it clear, make it robust) instead of trying to achieve perfection immediately, and pushes heavy use of TypeScript's type system to prevent entire classes of errors at compile time rather than runtime. The poka-yoke section is especially practical, showing how to use branded types and discriminated unions to make invalid states unrepresentable. It's opinionated about validating at boundaries once rather than everywhere, and about fixing small issues as you encounter them. Works well if you tend to over-engineer or if your team struggles with when to stop refactoring.

Kaizen: Continuous Improvement

Detailed Guide

Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.

When to Use

Apply within the requested scope for:

Code implementation and refactoring
Architecture and design decisions
Process and workflow improvements
Error handling and validation

Philosophy: Quality through incremental progress and prevention, not perfection through massive effort.

Limitations

Use this skill only when the task clearly matches the scope described above.
Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
