What it does

Subagent Orchestrator is an agent skill from sickn33/agentic-awesome-skills. Coordinate quota-aware parallel subagents for large, multi-file Antigravity tasks.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts (for example `README.md`, `examples/api-plus-frontend.md` and `examples/debug-mission.md`).

It sits in Agent Workflows, covering Subagents. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

When your agent uses it

  • Tasks that involve Subagents

Example prompts

  • “/subagent-orchestrator”

Requirements

  • Node.js

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. DECOMPOSE (before any agent runs)
  2. QUOTA ROUTING
  3. CONTEXT ISOLATION
  4. PARALLEL EXECUTION
  5. ERROR RECOVERY
  6. INTEGRATION CHECK

What it can do on your machine

Read from SKILL.md and the folder at commit 680176d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Subagent Orchestrator loads about 1.6k tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 602 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~26
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

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]

[2] ...
─────────────────────────────────────────

Wait for user to approve the Mission Brief before proceeding. If the user edits it, update and re-confirm. Never skip this step.

Phase 2 — QUOTA ROUTING

Before assigning models, apply this decision tree:

Is this task > 20 files OR > 500 lines of new code?
  YES → Use Gemini Flash for all agents. Reserve Sonnet for final review only.
  NO  → Is this task creative UI / complex logic / API design?
          YES → Use Sonnet for builder agent, Flash for all others.
          NO  → Use Gemini Flash for everything.

Model cost rules (never violate these):

  • Claude Opus → NEVER use in subagents. Too expensive.
  • Claude Sonnet → Max 1 subagent per mission.
  • Gemini Flash → Default for all subagents. Fast, cheap, separate quota pool.
  • Browser subagent → Always runs on its own pool. Use sparingly (1 per mission max).

Phase 3 — CONTEXT ISOLATION

Each subagent gets a scoped context packet. Never give all agents the full codebase.

For each agent, prepare:

AGENT CONTEXT PACKET — agent-[ID]
Files to read: [list only what this agent needs]
Files to write: [list only what this agent will create/edit]
Do NOT read: [explicitly exclude irrelevant files]
Knowledge: [paste only the relevant section of GEMINI.md]

Rule: If an agent doesn't need node_modules, package-lock.json, .next/, or dist/ — add them to a .antigravityignore before the agent runs.

Phase 4 — PARALLEL EXECUTION

Spawn agents in dependency order:

Round 1 (no dependencies): Run agents in parallel
Round 2 (depends on Round 1): Wait for all Round 1 outputs, then run
Round 3 (final): Integrate + verify

Between rounds, the orchestrator MUST:

  1. Collect each agent's output artifact
  2. Run a 3-point spot check:
    • Did the agent stay within its assigned scope?
    • Are there any import/export conflicts with other agents' outputs?
    • Did any agent produce a placeholder ("TODO", "implement later")?
  3. If any check fails → re-run that agent with corrected context. Do NOT continue.

Phase 5 — ERROR RECOVERY

If a subagent fails or produces broken output:

RECOVERY PROTOCOL
─────────────────────────────────────────
1. Do NOT re-run the full mission.
2. Identify the exact failure point.
3. Spawn a single repair agent with:
   - Only the broken file(s) as scope
   - The error message as context
   - Model: Gemini Flash (cheapest for repairs)
4. Validate the repair before continuing.
─────────────────────────────────────────

Never cascade a broken output to the next agent. Always fix before moving forward.

Phase 6 — INTEGRATION CHECK

After all agents complete, run a final integration sweep:

  • All imports resolve correctly
  • No duplicate function/variable names across files
  • No hardcoded values that should be env variables
  • No console.log left in production files
  • Types are consistent across components (TypeScript)
  • Build would succeed (npm run build mentally verified)

If any check fails, spawn one final repair agent scoped to the exact issue.

Quota Monitoring Rules

Track estimated usage throughout the mission:

EventQuota Impact
Agent spawnedLOW (setup)
File indexed (each)LOW
Tool call (file read/write)MEDIUM
Terminal commandMEDIUM
Browser subagent activatedHIGH
Thinking mode enabledVERY HIGH

If estimated usage crosses 60% of sprint quota mid-mission:

  • Pause and report: "Quota checkpoint: ~60% of sprint used. Continue or defer remaining agents?"
  • Switch remaining agents to Gemini Flash
  • Disable browser subagent if not yet started

Communication Rules

  • Announce which agent is running at all times
  • Show a compact progress bar between rounds:
    Mission Progress: ████████░░ 4/5 agents complete
Quota Status: ▓▓▓▓░░░░░░ ~40% sprint used
  • Never go silent for more than one agent turn
  • If blocked, say why explicitly — never just stop

Examples

See examples/ folder:

  • nextjs-feature.md — Building a full Next.js feature with 3 parallel agents
  • api-plus-frontend.md — Backend API agent + Frontend UI agent running in parallel
  • debug-mission.md — Repair mission for a broken build using minimal quota

Limitations

  • This skill coordinates agent planning; it does not provide a runtime scheduler or enforce quota limits automatically.
  • Parallel agents still need explicit scoping, review, and integration by the parent agent.
  • Do not use it when a single focused edit or direct answer would be faster and clearer.
