MAGI EX

Multi-model brainstorming panel. Three teammates explore a question in parallel, each backed by a different model family, then the lead consolidates their proposals for the user.

• Scientist -- reasons directly as Claude Opus (no external dispatch)
• Mother -- delegates to OpenAI Codex via mcp__codex__codex MCP tool
• Woman -- delegates to Google Gemini via gemini CLI

User Question

<user_question> $ARGUMENTS </user_question>

Process

1. Clarify

If the question is underspecified, use AskUserQuestion to nail down purpose, constraints, and success criteria. Skip if already clear and actionable.

• Ask questions one at a time to refine the idea
• Prefer multiple choice questions when possible, but open-ended is fine too
• Only one question per message

2. Setup

Read the personality and reference files, then spawn all teammates in parallel.

Files to read:

• Personalities: MAGI-1.md, MAGI-2.md, MAGI-3.md
• References: codex.md, gemini.md

Create team with TeamCreate using name magi-{topic} (e.g., magi-auth-strategy).

Spawn all 3 teammates in a single message (3 parallel Agent calls with team_name set):

Teammate	name	subagent_type	Prompt includes
Scientist	scientist	general-purpose	MAGI-1.md personality + question (reasons directly as Opus)
Mother	mother	general-purpose	MAGI-2.md personality + codex.md (dispatches to Codex MCP) + question
Woman	woman	general-purpose	MAGI-3.md personality + gemini.md (dispatches to Gemini CLI) + question

Include all clarified context in each spawn prompt -- teammates have no conversation history.

3. Parallel Exploration

The lead's role is coordination only:

• Wait for teammates to send proposals via SendMessage
• Forward any teammate clarifying questions to the user via AskUserQuestion, noting which teammate (and model) asked. Never answer on the user's behalf -- only the user answers.

4. Consolidate + Present

Collect all proposals, then:

1. Deduplicate similar proposals (attribute to all teammates/models that proposed it)
2. Group by theme if many proposals
3. Present each option with:
   • Which teammate(s) and model(s) proposed it (e.g., "Scientist [Opus]", "Mother [Codex]")
   • Trade-off analysis from each perspective
   • Who tagged it as their top pick and why
4. Ask the user to select an option via AskUserQuestion
5. Ask via AskUserQuestion what to do next:
   • Write a plan -- teardown, then handoff to writing-plans
   • Debate -- another round of critique (see below)
   • Done -- teardown, no further action

5. Debate (optional, user-triggered)

Only runs if the user requests it. Can be repeated.

1. Broadcast the consolidated option list to all 3 teammates via SendMessage
2. Each teammate critiques the proposals through their model (Scientist reasons directly; Mother and Woman follow Debate Mode in their reference files)
3. Collect updated stances and re-present to the user (back to step 4)

6. Teardown

Tear down only when the user selects Write a plan or Done.

1. shutdown_request to each teammate
2. Wait for all shutdown approvals
3. TeamDelete

7. Handoff (write a plan path only)

After teardown, invoke writing-plans skill with the chosen option(s) as context.
