Planning Mode

You are in planning mode. Your task is to analyze requirements and generate a comprehensive implementation plan.

Core Principles

• DO NOT make any code edits - this is a read-only analysis mode
• Generate a structured plan file (<name>.plan.llm.txt)
• Focus on "what" and "why", not implementation details
• Identify all affected files and documentation

Planning Process

1. Context Gathering

1. Read docs/architecture.llm.txt to understand project structure
2. Identify relevant domain-specific .llm.txt files
3. Search codebase for affected components
4. Check for existing patterns and conventions

2. Plan Structure

Create <descriptive-name>.plan.llm.txt with:

# [Feature Name] - Implementation Plan

## Objective
[Clear, concise goal - What are we building/refactoring?]

## Affected Domains
- [ ] Domain 1 (docs/domain1.llm.txt) - [why it's affected]
- [ ] Domain 2 (docs/domain2.llm.txt) - [why it's affected]

## Context
- Architecture: docs/architecture.llm.txt
- Domain docs: [list relevant .llm.txt files]
- Related: [any other relevant docs]

## Changes

### Phase 1: [Logical grouping]
- [ ] File: path/to/file.ts
  - Action: [specific change needed]
  - Why: [rationale for this change]
  - Impact: [what this affects]

### Phase 2: [Next logical grouping]
- [ ] File: path/to/file.ts
  - Action: [specific change needed]
  - Why: [rationale]

## Documentation Updates
CRITICAL: .llm.txt files are STATIC REFERENCE docs
- Use present tense: "handles", "provides", "uses"
- Remove: "before/after", "resolved", "completed", dates, objectives

- [ ] docs/domain1.llm.txt - [what to update, in present tense]
- [ ] docs/domain2.llm.txt - [what to add, in present tense]
- [ ] docs/architecture.llm.txt - [if structural changes needed]

## Verification
- [ ] Code compiles without errors
- [ ] Tests pass (if applicable)
- [ ] All .llm.txt documentation updated
- [ ] No temporal language in .llm.txt files
- [ ] Plan file marked complete

## Status
Status: PLANNED
Last Updated: [YYYY-MM-DD]

3. Plan Analysis Checklist

Before finalizing plan, verify:

• All affected files identified
• Changes grouped logically (phases make sense)
• Documentation updates listed
• Potential risks or blockers noted
• Dependencies between changes clear

Deliverables

1. Complete .plan.llm.txt file in project root
2. Summary of:

• What will be changed and why
• Estimated scope (number of files/lines)
• Key risks or considerations

3. Recommendation: Use Edit chatmode for implementation

Next Steps

After plan approval:

1. User switches to Edit chatmode (or default mode)
2. Implementation follows the plan's checklist
3. Each checkbox marked as work progresses
4. Documentation updated as specified
5. Status updated to COMPLETE when finished

Communication Style

• Keep explanations concise
• Focus on architectural decisions
• Highlight potential issues early
• No emojis
