antigravity-cli

antigravity-cli is a skill for Claude Code from amirkiarafiei/subagent-cli-skills. It costs 84 tokens per session (2,394 once invoked), scanned A, original, MIT.

A task-delegation skill that runs Antigravity CLI as a separate working session for large coding, research, or review tasks.

In plain words
What is it for?
Use it for broad refactors, batch edits, repository audits, deep exploration, web research, API-documentation searches, or other lengthy tasks.
Why use it?
It lets you delegate long, multi-step work while keeping the main conversation available, and its plan mode can perform read-only reviews without editing files.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

antigravity-cli 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 9d 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.

Antigravity CLI (subagent/task delegation)

Use Antigravity CLI to run a separate long-horizon pass over the repo: multi-step implementation, broad refactors, batch file writes, or deep exploration—similar to handing a task to a subagent. You stay orchestrator: smaller prompts, less context burn, often lower spend than doing the same work entirely in-session.

When to use Antigravity CLI

  • Large or multi-step work: several files, phases, or checkpoints (feature slice, migration, test suite, docs sweep).
  • Heavy code generation or editing: Antigravity drives automated tool use while you summarize outcomes and merge.
  • Read-only review passes: --mode plan cannot edit by construction, which makes it the right mode for audits, reviews, and "explain how this works" work.
  • Powerful Web Search: Delegate deep research or API documentation searches to Antigravity to leverage its integrated web search grounding.
  • Fresh tool stack: Native Google search grounding, MCP tools, sandbox protection, and other Antigravity-only capabilities.
  • User explicitly asks for Antigravity or "use Antigravity CLI for this."

When not to use

  • Small / single-step tasks answerable with one or two edits or a short explanation.
  • Tight feedback loops where the user wants rapid back-and-forth refinement in one thread.
  • Secrets or policy-sensitive flows—avoid piping credentials; redact before delegating.
  • Already-loaded context where duplicating the whole plan adds no value—handle locally.
  • Low ROI (Return on Investment): If the task requires high precision over a single line or if the time to compose the Handoff Table exceeds the time to simply edit the file locally. Delegation should only be used when the "mental offloading" outweighs the "handoff overhead."

Delegation and context (critical)

Isolated subagent context saves tokens but splits the story: Antigravity does not see the main session's full thread. Poor handoffs cause misread subtasks, conflicting assumptions (stack, style, APIs), and wasted edits.
