Diverse Perspectives Plan Creation

Produce a high-quality implementation plan by dispatching 2 focused perspective agents in parallel, then synthesizing their concrete proposals into a unified plan with clear rationale for every decision.

Why this works: A single planning pass tends to fixate on one approach. Two targeted perspectives expose blind spots and generate alternative proposals that the synthesis step can compare. The value comes not from volume of analysis, but from the contrast between perspectives — disagreements and different proposals are where the best insights emerge.

Quality target: The plan must be the best achievable — every decision justified, every requirement traced, every gap caught. Token usage and time are secondary to plan quality. No unnecessary agents, no generic observations — every agent output must contain actionable proposals.

Phase 0: Context Gathering

1. Analyze the user's request to understand scope and complexity
2. Use Glob, Grep, Read to explore relevant files in the codebase
3. Build a fact summary (under 1500 tokens):
   • Files involved and their relationships
   • Existing patterns and utilities to reuse
   • Tech stack constraints
   • Extract key signatures/structures per file, not full content

Vague Request Gate: If the request lacks clear scope or success criteria (e.g., "make it better"), ask the user to clarify before proceeding. Agents cannot compensate for missing intent.
