What it does

Collaborating With Antigravity is an agent skill from appautomaton/agent-designer. Delegate tasks to Google's Antigravity CLI (agy) for prototyping, debugging, code review, and research. Supports multi-turn sessions via SESSIONID. Successor to the retired Gemini CLI.

Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts, reference files and assets (for example `assets/prompt-template.md`, `references/agy-cli.md` and `references/shell-quoting.md`).

It sits in Development, covering Prototyping. The repository describes itself as: Portable SKILLs workspace for Claude Code, Codex, and Gemini — issue-driven workflows and cross-agent collaboration via bridge scripts with session continuity.

When your agent uses it

  • Tasks that involve Prototyping

Example prompts

  • “/collaborating-with-antigravity”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit b6e95dc. 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/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

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

  • Network

    No URLs in SKILL.md.

    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

Collaborating With Antigravity loads about 2.4k tokens when it runs, and up to ~4.1k if it reads all its reference files. Until then it costs about 54 tokens; SKILL.md has 1,054 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.1k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,054 words (~2,445 tokens).

“Use the Antigravity CLI (agy) as an independent collaborator while the calling agent stays responsible for verification, synthesis, and final user-facing decisions. Antigravity CLI is Google's replacement for the retired Gemini CLI (hosted auth shut off 2026-06-18).”
