Simplify

Simplify — Code Quality Review and Improvement

Review changed code for reuse, quality, and efficiency, then fix any issues found.

When to Use

• After PDCA Check phase reaches >= 90% match rate.
• When code review is needed before merging.
• When refactoring is requested.

4-Step Workflow

Step 1: Collect Changed Files

Run git diff --name-only (and git diff --cached --name-only for staged files) to identify all recently changed files.

Filter to relevant source files only (exclude lockfiles, generated files, build artifacts).

Output: List of files to review.

Step 2: Analyze Each File

For each changed file, analyze for:

Output: Issue table per file.

Step 3: Apply Improvements

For each identified issue:

1. Apply the fix automatically using replace tool.
2. Ensure the fix does not change external behavior.
3. Preserve existing test coverage.

Rules:

• Do NOT change public API signatures without confirmation.
• Do NOT remove code that appears unused if it is exported.
• Keep changes minimal and focused.

Step 4: Output Change Summary

Present a summary table of all changes made:

Final output:

• Total files reviewed
• Total issues found
• Total issues fixed
• Lines added / removed

References

• Use project's existing linting rules and conventions.
• Respect .eslintrc, .prettierrc, or equivalent config files.
