Who it is forA developer who needs a placeholder mascot or illustration for a project and wants it generated from the terminal.
The problemCreating a simple illustration breaks the coding flow and needs a separate tool.
The outcomeA PNG file saved at the path you name, such as assets/mascot.png.
What you need first
- Antigravity CLI (agy) installed and authenticated
- Node.js installed
- Claude Code or OpenAI Codex (Pi and OpenCode are also supported per the README)
Steps
- Install the Antigravity CLI with
curl -fsSL https://antigravity.google/cli/install.sh | bash, then confirm withagy --version. - Install the plugin in Claude Code with
claude plugin marketplace add keli-wen/agy-staffandclaude plugin install agy@agy-staff, or in Codex withcodex plugin marketplace add https://github.com/keli-wen/agy-staffandcodex plugin add agy@agy-staff. - Restart the harness.
- Run
/agy:staffer generate a pixel-art robot mascot, save it as assets/mascot.pngin Claude Code, or the same text with$agy:stafferin Codex. - Open the saved file and check it before committing it.
Prompt for your agent
Using the keli-wen/agy-staff plugin, ask the staffer persona to generate <image description> and save it to <output path> in <repo>. Expect a PNG at that path. Verify that the file exists and opens as an image.
Caveat. The README reports one trial that produced a 1024x1024 PNG in about 30 seconds on agy v1.1.15, and actual time depends on the task and environment.
