At a glance

Runs the Antigravity CLI headlessly with the agy command to analyze a repository or carry out a coding task, then checks its JSON result and the diff.

  • Works in 3 steps: Set the Bash working directory to the… → Check availability with command -v agy.… → Run one task and exit
  • Delegating a repository analysis task to Antigravity CLI
  • SKILL.md covers Run and Authentication And Permissions
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

The agent first sets the working directory to the project you named, applies a finite timeout (normally 10 minutes) and confirms the agy command exists; if it is missing, it stops and asks you to install Antigravity CLI in Code Mate. It then runs a single print-mode task with JSON output and reads the status field, treating any non-success status or unparseable output as a failure.

Headless runs fail until Antigravity is signed in, and the agent is told never to start a login flow or touch credentials; it asks you to finish setup instead. Because the tool auto-approves file reads and writes inside the workspace, read-only tasks should use a disposable copy, edits should name specific files, and the flag that skips every permission prompt is forbidden. The diff is inspected before success is reported.

When your agent uses it

  • Delegating a repository analysis task to Antigravity CLI
  • Comparing Antigravity's answer with another coding agent's on the same task
  • Running an approved edit through Antigravity on named files only

Example prompts

  • “Ask Antigravity CLI to summarize the module layout of ~/projects/billing-api.”
  • “Have Antigravity fix the failing date parser test, touching only src/dates.py, and show me the diff.”
  • “Run this refactor review in Antigravity as well and compare it with what you found.”

Requirements

  • Antigravity CLI (the agy command) installed and signed in through Code Mate

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Set the Bash working directory to the exact project the user named and set a finite timeout, normally 10 minutes.
  2. Check availability with command -v agy. If it is missing, stop and ask the user to install Antigravity CLI in Code Mate.
  3. Run one task and exit

What it can do on your machine

Read from SKILL.md and the folder at commit dd0767e. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    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

Antigravity CLI Runner loads about 531 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 293 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~531

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); files beside SKILL.md are not scanned.

description
Runs Antigravity CLI headlessly for repository analysis and coding tasks. Use when the user asks to delegate work to Antigravity CLI or compare its result with another coding agent.

Antigravity CLI

Run

  1. Set the Bash working directory to the exact project the user named and set a finite timeout, normally 10 minutes.
  2. Check availability with command -v agy. If it is missing, stop and ask the user to install Antigravity CLI in Code Mate.
  3. Run one task and exit:
bash
agy -p "<prompt>" --output-format json

Pass the prompt as one quoted argument. Print mode waits up to --print-timeout (5m by default); pass a shorter value when the caller's own timeout is tighter.

Parse the JSON result and read its status field: anything other than a success status is a failure, and error carries the reason. Treat unparseable output as failure too. Never start interactive Antigravity or an authentication flow.

Authentication And Permissions

Antigravity refuses to run headlessly until it is signed in — it returns status: "ERROR" with authentication failed or timed out and tells you to run agy to log in. Do not do that: stop and ask the user to finish Antigravity setup in Code Mate. Never request, read, print, or copy credentials.

Headless mode inherits the permission mode persisted in user settings, and reading and writing files inside the active workspace are auto-approved by default — the default is not a read-only boundary, and a prompt cannot make it one. Do not run it against a writable project for a read-only task. Use a disposable or read-only copy instead. Run against the real project only when the user explicitly requests workspace changes, constrain the directory, and inspect the diff afterward. Never pass --dangerously-skip-permissions, which auto-approves every tool request including outside the workspace.

Example: for an approved edit, ask Antigravity to touch only named files, run it in that project, parse the response and any reported error, and inspect the resulting diff before reporting success.
