Refine GitHub Issue Skill

You are helping to refine a GitHub issue into a well-defined development task. Extract the issue number from the user's request (e.g., "refine github issue 23" → issue #23, "refine issue #45" → issue #45, "refine 67" → issue #67).

IMPORTANT: Use the TodoWrite tool to track your refinement process with these tasks:

1. Fetch issue details from GitHub
2. Gather context from codebase
3. Ask clarifying questions (if needed)
4. Create refinement document
5. Update GitHub issue

Step 1: Fetch Issue Details

Run: gh issue view ${ISSUE_NUMBER} --json title,body,labels,state,comments,assignees

Review the complete issue context including:

• Title and description
• Current labels and state
• All comments and discussion
• Assignees (if any)

Step 2: Gather Codebase Context

Use the Task tool with subagent_type=Explore to:

• Find relevant code files related to the issue topic
• Review CLAUDE.md for architecture patterns and conventions
• Check DEVELOPMENT_PLAN.md (if exists) for related features
• Search for similar implementations or patterns already in use
• Identify affected components and dependencies

Example searches:

• Find feature-related files: Use Glob with patterns like **/*<feature>*.kt
• Search for related code: Use Grep for keywords from the issue
• Understand architecture: Read relevant screen/ViewModel/UseCase files

Step 3: Analyze and Clarify

Based on the issue and codebase context:

If requirements are unclear, use AskUserQuestion to clarify:

• Specific behavior expectations
• UI/UX preferences
• Technical approach preferences (e.g., which library, pattern)
• Scope boundaries (what's in/out)
• Edge cases and error handling requirements
• Testing expectations

If requirements are clear, proceed to refinement.

Step 4: Create Refinement Document

Structure your refinement as follows:

User Story

As a [user type] I want [goal] So that [benefit]

Technical Context

• Affected Components: List screens, ViewModels, UseCases, data sources
• Architecture Pattern: Follow CLAUDE.md conventions (MVI/MVVM, Clean Architecture)
• Dependencies: Existing features or models this depends on
• Integration Points: Where this connects to existing code

Acceptance Criteria

Clear, testable criteria in checkbox format:

• Criterion 1 (specific and measurable)
• Criterion 2 (specific and measurable)
• Criterion 3 (specific and measurable)

Implementation Guidance

Data Layer (if applicable):

• Room entities to create/modify
• Data source interfaces
• Repository changes

Domain Layer (if applicable):

• Use cases to implement
• Domain models
• Business logic

UI Layer (if applicable):

• Screens to create/modify
• ViewModel state and events
• Navigation changes
• Compose components

Other Considerations:

• Notification system integration
• Background work (WorkManager)
• Dependency injection updates
• Testing strategy

Technical Considerations

• Performance implications
• Security concerns
• Backwards compatibility
• Error handling approach
• Logging/debugging needs

Out of Scope

Explicitly list what this issue does NOT include to prevent scope creep.

Step 5: Update GitHub Issue

Update the issue using: gh issue edit ${ISSUE_NUMBER}

Add this refined content to the issue body:

## Refinement

[Include the full refinement document from Step 4]

---
*Refined by Claude Code on [date]*

Then add the "Refined" label:

gh issue edit ${ISSUE_NUMBER} --add-label "Refined"

Tips for Natural Language Usage

This skill understands various phrasings:

• "refine github issue 23"
• "refine issue #45"
• "refine 67"
• "help me refine issue 12"
• "can you refine gh issue 8"

Extract the issue number and follow the 5-step process above.

Now begin: Fetch issue details and start the refinement process.
