MAGI EX

Multi-model deliberation system. Spawns Scientist, Mother, and Woman teammates backed by Claude Opus, OpenAI Codex, and Google Gemini to explore a question in parallel, then consolidates their proposals for the user.

Checklist

Follow these steps in order.

1. Clarify the question
2. Set up agent team
3. Parallel exploration
4. Consolidate and present options
5. Wait for user decision (write a plan, debate, or done)
6. Tear down agent team

The Process

User Question

<user_question> $ARGUMENTS </user_question>

Clarify

Before spawning teammates, the lead asks via AskUserQuestion to understand the idea or topic:

• 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
• Focus on understanding: purpose, constraints, success criteria

Skip if the question is already clear and actionable. Include all clarified context in teammate spawn prompts.

Setup

• Read all 3 template files: MAGI-1.md, MAGI-2.md, MAGI-3.md
• Read both reference files: codex.md, gemini.md
• TeamCreate with a descriptive team name magi-{topic} (e.g., magi-auth-strategy)
• Spawn all 3 teammates in a single message (3 parallel Task calls):

• Set team_name on each Task call to the team name from above
• Teammates don’t inherit the lead’s conversation history — include all context in the spawn prompt

Explore in Parallel

Teammates begin working immediately upon spawning. The lead’s role is coordination only:

• Wait for teammates to send their proposals via SendMessage
• Forward teammate clarifying questions to the user via AskUserQuestion — note which teammate (and which model) asked
• Your role is to wait and coordinate — teammates produce all proposals

Each teammate follows their own model-specific checklist defined in their template.

Consolidate + Present

Lead collects all proposals from the 3 teammates, then:

1. Deduplicates similar proposals (attributing to all teammates/models that proposed it)
2. Groups by theme if there are many proposals
3. Presents 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. Asks the user via AskUserQuestion to select an option (one option per choice)
5. Asks the user via AskUserQuestion what to do next:
   • Write a plan — triggers teardown + handoff to writing-plans with the selected option
   • Debate — teammates critique each other’s proposals (triggers debate round below)
   • Done — shut down the agent team, no further action

Optional Debate (user-triggered)

Only runs if the user requests it. When triggered:

1. Lead broadcasts the consolidated option list to all 3 teammates via SendMessage
2. Each teammate sends the proposals to their model for critique:
   • Scientist (Opus): reasons directly about other proposals
   • Mother (Codex): calls mcp__codex__codex-reply with saved threadId
   • Woman (Gemini): pipes full context + proposals to gemini -p -
3. Each teammate sends their model’s critique back to the lead via SendMessage
4. Lead collects updated stances and re-presents to the user

One round per debate request. The user can trigger multiple sequential debates.

Teardown

When to tear down

• User selects Write a plan
• User selects Done

Keep teammates alive during the debate loop

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

Shutdown sequence

1. shutdown_request to each teammate (Scientist, Mother, Woman)
2. Wait for all shutdown approvals
3. TeamDelete (fails if teammates are still active)

Handoff (write a plan path only)

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