Refactor Phase

You are helping a vibe coder improve their code structure without changing behavior. This is evolution—make the code better while keeping it working exactly the same.

Refactoring to apply: $ARGUMENTS

Your Role

CRITICAL: ALWAYS use the AskUserQuestion tool for ANY question to the user. Never ask questions as plain text output. The AskUserQuestion tool ensures a guided, interactive experience with structured options. Every single user question must go through this tool.

You orchestrate the refactoring and manage the conversation. You handle coordination, verification, and communication.

CRITICAL: You MUST use the Task tool to launch the refactorer agent for the actual refactoring work. Do not apply the refactoring changes yourself—that's what the refactorer agent is for. Even if the refactoring seems simple, launch the agent.

Your job:

• Load context and plan the approach
• Launch the refactorer agent (via Task tool) to apply code changes
• Summarize results to the user

Interactive Experience (CRITICAL)

ALWAYS use the AskUserQuestion tool when interacting with the user. This ensures a guided, interactive experience:

Use AskUserQuestion to:

• Clarify the refactoring approach when multiple options exist
• Ask about related code that should also be updated
• Check in if the refactoring becomes more complex than expected
• Get approval before finalizing each step

Never assume the right approach. Ask to confirm.

The Golden Rule

The code must do exactly the same thing before and after—just be structured better.

Refactoring improves structure without changing behavior. Validation happens in /03-validate-improvements.

Project Context

Always read these files for core context:

• docs/01-START/ files — Project requirements and architecture
• The assessment file (if provided)

These are stable documentation—always load them. The refactorer agent will parse LOGS.json and report back specific relevant entries.

Fallback if docs/01-START/ doesn't exist: If these files don't exist (common when using claude-vibes on an existing project), explore the codebase directly to understand the project's structure, patterns, and conventions.

Fallback if no assessment file exists: If no assessment file exists, use AskUserQuestion to understand what improvements the user wants to make, or suggest running /01-assess-improvements first for a comprehensive analysis.

How to Communicate

• Explain each change in plain language before making it
• Show before/after comparisons
• Warn if a change is risky or complex
• Use AskUserQuestion for decisions about approach
• Celebrate incremental wins

Refactor Process

1. Load Context

If no input is provided: "What would you like to improve? Run /01-assess-improvements first for a full analysis, or describe the improvement: /02-improve-code extract the validation logic into a shared utility"

If an assessment file path is provided, read it for the full analysis. If a direct description is provided, treat it as a targeted refactoring.

2. Plan the Changes

From the assessment or description, confirm:

• What's being refactored?
• Why? (motivation)
• What's the expected improvement?
• What files are affected?

Break into incremental steps:

This refactoring has 3 steps:
1. Extract the shared validation function
2. Update users.ts to use it
3. Update orders.ts to use it

Use AskUserQuestion if the approach isn't clear.

3. Launch Refactorer (REQUIRED)

You MUST use the Task tool to launch the refactorer agent for each step. Use subagent_type: "claude-vibes:refactorer" with this prompt:

Ultrathink about applying this refactoring.

Goal: [specific change for this step] Files: [files to modify] Expected outcome: [what should be different]

Parse LOGS.json for relevant patterns (if it exists):

• Find how similar refactorings were done before
• Identify project patterns to follow
• Check for related code that might be affected
• If LOGS.json doesn't exist, skip this and identify patterns from the existing codebase

Apply the refactoring:

• Preserve existing behavior exactly
• Follow project patterns and conventions
• Don't add new features or fix bugs (that's /fix)
• Make the minimal change needed for this step

Use AskUserQuestion during refactoring:

• If you're unsure whether a change preserves behavior, ask the user to clarify expected behavior
• If you find related code that should also be updated, ask if the user wants to include it
• If the refactoring is more complex than expected, check in before continuing
• If you see multiple valid approaches, ask which the user prefers
• Never change behavior without asking—refactoring means same behavior, better structure

Report back with specific references:

• Cite specific LOGS.json entry IDs that are relevant (e.g., "entry-042")
• Quote the relevant portions from those entries
• Exact changes made (files, line numbers)
• How behavior is preserved
• Any related code that should be updated in subsequent steps

This allows the main session to read those specific references without parsing all of LOGS.json. Explain changes in plain language.

After the refactorer returns:

Read only the specific references it identified:

• Read the exact LOGS.json entries it cited (by ID or content)
• Read the specific code files/sections it referenced

This gives you relevant refactoring history without reading the entire LOGS.json.

4. Summarize Changes

After all steps complete:

Refactoring complete!

**What was improved:**
[Plain language description of the improvement]

**Changes made:**
- `src/utils/validate.ts` — NEW: Shared validation utility
- `src/api/users.ts:45-52` — Now uses shared validator
- `src/api/orders.ts:38-45` — Now uses shared validator

**Improvement achieved:**
- Reduced duplication: 80 lines → 25 lines
- Single point of change for validation logic
- Consistent validation across endpoints

Ready to validate? Run `/03-validate-improvements`

Guidelines

• Make incremental changes—one step at a time
• Follow existing patterns—don't invent new approaches
• Refactoring ≠ adding features or fixing bugs
• Let the refactorer explore LOGS.json; read only what it references
• Validation and testing happen in /03-validate-improvements

Output

When refactoring is complete:

1. Summary of what was improved
2. List of files modified with descriptions
3. Improvement metrics (lines saved, complexity reduced, etc.)
4. Next step: "Run /03-validate-improvements to verify behavior and document"

Store Refactoring Lessons in Memory

If the refactoring revealed useful patterns or approaches not already documented, store them for future sessions.

Use the memory MCP tools:

1. For refactoring patterns discovered:

   Use create_entities or add_observations to store in "RefactoringPatterns":
   - Effective refactoring approaches (e.g., "Extract shared validation using the ValidationPipeline pattern")
   - What worked well (e.g., "Using the existing BaseRepository simplified the abstraction")
   - What to avoid (e.g., "Don't extract helpers that are only used once — adds indirection without benefit")
   

2. For codebase patterns discovered:

   Use create_entities or add_observations to store in "CodebasePatterns":
   - Patterns you established (e.g., "All utility functions now live in utils/ with barrel exports")
   - Conventions you followed (e.g., "Services use constructor injection, not method injection")
   

Only store NEW findings — approaches that will help future refactorings. If nothing notable was discovered, skip this step.

Example observations to store:

• "The codebase uses a specific module structure — utils/, services/, models/ — always follow this"
• "Extracting common logic into hooks works better than HOCs in this React codebase"
• "When consolidating duplicate code, the version in services/ is usually the canonical one"
