Overview

This skill is the "execution hand" for the code-quality-audit skill. It transforms strategic advice into concrete code changes by:

1. Contextual Analysis: Synthesizing the "Why" (from audit.md) and "How" (from improvements.md) with the current source code state.
2. Implementation Planning: Creating a detailed refactor-plan.md that outlines each atomic step.
3. Safe Execution: Applying changes only after user review and verifying each step with tests or build checks.

Activation Rules

Triggers ONLY when the user asks to:

• "Implement the refactorings"
• "Execute the improvements roadmap"
• "Plan and apply refactors from the audit"
• "Fix the issues listed in improvements.md"

Prerequisites:

• audit.md and improvements.md must already exist in the workspace.
• Access to the source code files mentioned in the roadmap.

Workflow

Phase 1: Context Triangulation

• Read Analysis: Load audit.md and improvements.md.
• Scan codebase: Read the files and line numbers referenced in those documents.
• Verify Consistency: Ensure the code logic matches the audit's observations. If the code has been significantly modified since the audit, inform the user and suggest a re-audit.

Phase 2: Implementation Roadmap (refactor-plan.md)

Create a refactor-plan.md (if it doesn't already exist or if requested) with the following structure:

# Implementation Plan: [Refactor Name/Batch]

## Summary
Brief description of the goals (e.g., "Untangling Auth Logic").

## Stages
### Stage 1: [Name]
- **Target Files**: [List paths]
- **Action**: [Brief description of the change]
- **Verification**: [Command to run, e.g., `npm test`]

### Stage 2: [Name]
...

Present this plan to the user and wait for approval for individual stages or the whole batch.

Phase 3: Execution & Verification

For each approved stage:

1. Apply Changes: Use replace_file_content or multi_replace_file_content for atomic updates.
2. Verify Integrity:
   • Run a syntax check or build (e.g., tsc, go build).
   • Run relevant tests (e.g., pytest, jest).
3. Capture Regressions: If a change breaks the build/test, revert immediately or fix it if the solution is obvious.
4. Report Progress: Inform the user which stages are complete.

Standards for Implementation

• Atomic Commits/Changes: Don't refactor everything in one giant tool call. Group related changes into logical stages.
• Maintain Consistency: If you rename a symbol, search for and update all call sites across the project.
• No Over-Engineering: Stick to the "Suggested Approach" unless it's clearly incorrect for the current code.
• Transparency: Always explain what you are about to change before doing it.

Quality Assurance

• Do not attempt to refactor without reading the source code first.
• If a suggested refactor in improvements.md is too vague, ask the user for clarification before planning.
• If no tests are available, manually verify the change by reading the resulting file.
• Verify each change resolves the specific issue from the audit. Do not drift into unrelated refactors.
• Output goes under the user's name. A refactor that introduces regressions or misses the original problem reflects on them.
