Phase 2 — Build a Planning Brief

Before fanning out, build a preliminary orientation that each agent will receive. This is a starting point, not ground truth — agents are expected to contradict it if their own research leads elsewhere.

The brief should include only:

1. Goal — what needs to be built or changed, and why.
2. Constraints — technical constraints explicitly stated by the user (not inferred).
3. Codebase context — file and directory paths discovered in Phase 1. No conclusions, no risk assessments — just locations.
4. Open questions — unresolved areas where the user has not stated a preference.

Keep the brief under ~50 lines. Do not answer the open questions — leave them open so agents form independent views. The agents will use search, read and terminal tools to dig into specifics.

Phase 3 — Independent Planning

Spawn all subagents in parallel at once:

• One subagent per model using the model parameter. Prepend the system preamble to the planner prompt below.
• Do not share one agent's proposal with another before this phase completes.

Phase 4 — Consensus Synthesis

Compare the three proposals and classify into:

1. Consensus approach — two or more agents independently propose the same approach, architecture, or sequencing. These form the backbone of the plan. High confidence.
2. Alternatives — agents propose different viable approaches for the same aspect. Present each with trade-offs and a recommendation. Let the user decide or pick the approach with the strongest rationale.
3. Consensus risks — risks or concerns flagged by two or more agents independently. These are high-confidence and should be addressed in the plan.
4. Single-agent insights — a useful idea only one agent surfaced. Keep if well-evidenced, note it came from one model.

Drop vague suggestions, over-engineering proposals, and speculative concerns.

Phase 5 — Debate (optional)

Trigger this phase when the user asks to "debate", "discuss", or "cross-plan", or when Phase 4 produces significant alternatives that could benefit from deliberation.

1. Share the anonymized synthesis (without attributing which model said what) back to each council agent.
2. Ask each agent to evaluate the alternatives and state which approach they'd recommend, with evidence.
3. Spawn all subagents in parallel at once.
