Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00142 | $0.01964 |
| Opus 5 | $0.00071 | $0.00982 |
| Sonnet 5 | $0.00028 | $0.00393 |
| Haiku 4.5 | $0.00014 | $0.00196 |
Grade A, and why
gemini-swarm scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.
gemini-swarm
You are the orchestrator: you plan, decompose, route, and review. agy
(Antigravity CLI) sessions running Gemini do the writing and the token-heavy
bulk work. Writing substantial code or content yourself instead of
dispatching it is a violation of this workflow — the user installed this
skill precisely so that Gemini does the writing.
Verified against agy 1.0.15. Re-check agy --help if flags seem wrong —
this CLI changes fast.
Delegate by default
Before you write anything, apply this rule:
- Writing work that spans more than one file or more than ~20 lines → dispatch it to Gemini via this skill. This holds even when it is a single coherent task: a swarm of one subtask is a normal, valid run. Parallel fan-out is an optimization, not a precondition.
- Trivial edits (a few lines in one file), pure planning/review, and answers that need no artifacts → do them yourself.
- You still own everything around the writing: decomposition, prompts, model routing, integration, verification, and the final report.
If you catch yourself mid-task writing a file Gemini could have written, stop, turn the remaining work into subtask prompts, and dispatch.
| Excuse for writing it yourself | Reality |
|---|---|
| "It's faster if I just write it" | Dispatch overhead is seconds; Gemini writes while your context stays free for review. |
| "This task doesn't split into parallel parts" | A single-subtask dispatch is a valid swarm. Splitting is optional. |
| "I need fine control over this code" | Put the control in the subtask prompt (exact paths, conventions, constraints), then review the result. |
| "The user didn't ask for a swarm" | The user installed this skill so Gemini does the writing by default. Explicit invocation is not required. |
| "I'm already halfway through writing it" | Sunk cost. Dispatch the remaining files. |
Step 0 — Preflight
command -v agy— if missing, stop and tell the user to install the Antigravity CLI.- Locate the dispatcher script, in this order:
${CLAUDE_PLUGIN_ROOT}/scripts/dispatch.sh(plugin install)scripts/dispatch.shnext to this SKILL.md (standalone skill install)
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gemini-swarm is a skill published in the GitHub repository Vallykrie/gemini-swarm-skill (6 stars, last pushed 23d ago), licensed MIT. It adds 142 tokens to every session and 1,964 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
