Subagent Orchestrator

A quota-aware, parallel subagent coordination skill for Antigravity 2.0. Turns one big task into a set of isolated, efficient agent missions — without burning your weekly quota.

---

Use this skill when

• A task spans 3+ files or components
• You want multiple agents working at the same time
• You've hit quota issues mid-task before
• The task involves both planning AND building
• You need browser agent + code agent + terminal agent running together

Do not use this skill when

• Editing a single file or fixing one bug
• Writing a quick script under 50 lines
• Asking a question or generating a plan only

---

Phase 1 — DECOMPOSE (before any agent runs)

Before spawning any subagent, the orchestrator MUST produce a Mission Brief. Announce:

"Running subagent-orchestrator skill. Decomposing task into isolated missions."

Then output a Mission Brief in this format:

MISSION BRIEF
─────────────────────────────────────────
Goal: [one sentence, what done looks like]
Total Agents: [N]
Quota Strategy: [FLASH / SONNET / MIXED]
Expected Token Cost: [LOW / MEDIUM / HIGH]

AGENTS:
[1] ID: agent-001
    Role: [e.g. Planner / Builder / Tester / Browser]
    Scope: [exact files or URLs this agent touches]
    Model: [Gemini Flash / Claude Sonnet]
    Input: [what it receives]
    Output: [what it produces]
    Depends on: [none / agent-001]
