Plan Research (Plan Mode)

Input

Optional implementation guidelines: $ARGUMENTS Examples:

• "Focus on SSE streaming patterns"
• "Use React Query for data fetching"
• "Based on the pattern from ALG-14"

Steps

1. Enter plan mode: Call the EnterPlanMode tool to begin planning.

2. Get current feature from branch:

   BRANCH=$(git rev-parse --abbrev-ref HEAD)
   # Extract: alg-27-feature-name -> 27
   NUM=$(echo "$BRANCH" | grep -oE 'alg-([0-9]+)' | grep -oE '[0-9]+')
   

3. Read the spec:

   • Read specs/alg-${NUM}-*/spec.md
   • Extract user stories, requirements, and scope

4. Incorporate user guidelines (if $ARGUMENTS provided):

   • Parse the implementation guidance
   • Use as constraints for technology choices
   • Note any specific patterns or libraries mentioned

5. Explore codebase to identify:

   • Existing patterns to follow (search for similar implementations)
   • Files that will need modification
   • Technologies currently in use
   • External documentation to reference

6. Propose research plan in the plan file: Write to the plan file (NOT research.md yet) with:

   • Key Decisions to make (numbered 1, 2, 3...)
   • Technologies to evaluate
   • Codebase Patterns to examine
   • Files likely to be modified
   • External Resources to consult

7. Exit plan mode: Call ExitPlanMode to get user approval of the research plan.

8. After approval, conduct research:

   • Make the key decisions with rationale
   • Document alternatives considered
   • Extract relevant code patterns from codebase
   • Reference external documentation

9. Write research.md:

   # Research: {Feature Title}
   
   **Date**: {ISO date}
   **Feature**: ALG-{NUM}
   **Implementation Guidance**: {$ARGUMENTS if provided}
   
   ## Executive Summary
   
   {Brief overview of key decisions}
   
   ## Key Decisions
   
   ### 1. {Decision Title}
   
   **Decision**: {What was decided}
   **Rationale**: {Why this approach}
   **Alternatives Considered**:
   
   - {Alternative 1}: {Why rejected}
   - {Alternative 2}: {Why rejected}
   
   ## Implementation Patterns
   
   {Code snippets from codebase showing patterns to follow}
   
   ## Files to Modify
   
   - `path/to/file.ts`: {What changes}
   

10. Commit the research:

    git add specs/alg-${NUM}-*/research.md
    git commit -m "spec: ALG-${NUM} - research and decisions"
    

Notes

• Research should validate decisions against existing codebase patterns
• Include actual code snippets showing how similar things are done
• Reference specific file paths for implementation guidance
