Multi-Model Collaborative Planning

Advanced skill — Uses external model backends (Codex, Gemini) for collaborative analysis and planning.

Usage

/multi-plan <task description>

Workflow

Phase 1: Context Retrieval

• Enhance prompt using MCP tools (if available)
• Retrieve project context via semantic search
• Verify requirement completeness (score >= 7/10 to proceed)

Phase 2: Multi-Model Analysis

• Distribute requirements to multiple model backends in parallel
• Each backend analyzes from its perspective (backend logic vs frontend UX)
• Cross-validate results: identify consensus and divergence

Phase 3: Plan Synthesis

• Synthesize analyses into step-by-step implementation plan
• Include: task type, technical solution, implementation steps, key files, risks
• Save plan to .codex/plan/<feature-name>.md

Plan Output Format

## Implementation Plan: <Task Name>

### Technical Solution
<Synthesized solution>

### Implementation Steps
1. Step 1 - Expected deliverable
2. Step 2 - Expected deliverable

### Key Files
| File | Operation | Description |
|------|-----------|-------------|

### Risks and Mitigation
| Risk | Mitigation |
|------|------------|

Key Rules

1. Plan only, no implementation
2. External models have zero filesystem write access
3. All modifications by the orchestrator
4. Present plan for user approval before execution
