Subagent Orchestrator — Antigravity 2.0 Skill
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 in 30 minutes.
What it does
- Splits complex tasks into isolated agent missions before any code is written
- Routes tasks to the cheapest model that can handle them (Flash by default)
- Runs independent agents in parallel, not in sequence
- Monitors quota usage throughout and pauses if limits are approaching
- Recovers from agent failures without re-running the whole mission
- Runs a final integration check before declaring the mission complete
Install
One command (Windows PowerShell):
node scripts/install.js
Manual install — copy this folder to:
Windows: %USERPROFILE%\.agents\skills\subagent-orchestrator\
Mac/Linux: ~/.agents/skills/subagent-orchestrator/
Then restart your Antigravity session.
Usage
The skill auto-activates when your task:
- Spans 3+ files or components
- Needs parallel agents (UI + API, planner + builder, etc.)
- Has quota risk (large codebase, many tool calls expected)
Or trigger it manually:
"Use subagent-orchestrator to build the auth flow"

Quota reference (quick)
| Model | Cost |
|---|---|
| Gemini Flash | 1x (default for all subagents) |
| Claude Sonnet | ~4x (max 1 per mission) |
| Claude Opus | Never use in subagents |
| Mission size | Est. sprint used |
|---|---|
| 1-file repair | < 5% |
| Single feature | 15–25% |
| Full flow (auth, API, UI) | 30–45% |
Contributing
This skill was built to fill a real gap — the community's existing subagent skills had no quota management, no parallel coordination, and no error recovery.
