About kaizen
kaizen is a skill for incremental quality improvements in code, architecture, and workflows. It guides developers to make scoped changes and emphasizes validation rather than large, sweeping efforts.
Key features
- 01Incremental code improvement
- 02Refactoring and design guidance
- 03Workflow and process improvement
- 04Error handling and validation
- 05Scope and safety constraints
Use cases
- 01Refining a small code change
- 02Reviewing an architecture decision
- 03Improving a development workflow

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.
Example
When a total accepts NaN, add finite-number validation at its input boundary,
verify finite/negative cases, and review the small diff before broader refactoring.
Do not treat an example snippet as evidence that tests passed.
