A layered plugin around the agy CLI — not a thin wrapper. Structured
JSON-schema review, background jobs with persisted state, a forwarding delegate subagent, web
research, and native image generation, all covered by a node:test
suite that never calls the real binary.
Install
Run these inside Claude Code, in order. Each card has a one-click copy button.
Tells Claude Code where to find the plugin.
/plugin marketplace add Or4cu1o/antigravity-plugin-cc
Pulls the plugin into the user-scope plugin cache.
/plugin install agy@agy-plugin-cc
Activates the slash commands and runs the install/auth check.
/reload-plugins /agy:setup
Commands
Every command is a thin markdown wrapper around the same companion script — no flag parsing in the markdown, only execution-mode decisions.
JSON-schema-enforced review of your working tree or a branch diff. Read-only, not steerable.
Same structured schema, but steerable — questions design choices, tradeoffs, and assumptions, not just defects.
Routes through a pure forwarding subagent to agy. Write-capable by default; supports --resume and --background.
The cheapest path: single prompt, verbatim answer, no persisted job, always foreground.
Native image generation via agy's built-in tool, saved to an absolute path you choose.
Delegates a topic to search_web + read_url_content for a sourced answer.
Deeper investigation across multiple sources. Defaults to running in the background without asking.
Running and recent jobs for this repository, scoped to the current Claude session.
The stored final output for a finished job, plus the agy conversation ID to resume it directly.
Terminates an active background job and marks it cancelled in the job store.
Verifies agy is on the box and signed in. Also toggles the optional stop-time review gate.
Why a full port, not a wrapper
$CLAUDE_PLUGIN_DATA.
stream-json NDJSON contract and the fixed-scratch-directory quirk in agy's run_command tool were both found and fixed by running against the actual CLI, not just documentation.
--resume, and the stop-review gate are all scoped to the Claude session that created them — a background task from one session can't leak into another.
Tested
Pure node:test, no dependencies. A fake agy binary is injected into PATH for every test — nothing ever calls the real CLI during npm test.
