gemini-plugin-cc: Instructions file for Claude Code

CLAUDE.md

gemini-plugin-cc CLAUDE.md is an instructions file for Claude Code from haunchen/gemini-plugin-cc. It costs 6,299 tokens per session, scanned B, original, MIT.

A set of Claude Code instructions for a marketplace containing two plugins that use Google's Gemini through the Antigravity command-line tool. One provides commands for code work, and the other describes images before Claude reads them.

In plain words
What is it for?
It is for understanding, maintaining, or extending the Gemini and Gemini-images plugins, including their marketplace registry, commands, agent definitions, and automatic image-reading hook.
Why use it?
It explains how the plugins, commands, hooks, and shared Google login fit together. It also distinguishes actions that only inspect code from the implementation command that edits 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 B, and why

gemini-plugin-cc CLAUDE.md scanned grade B with 1 finding 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 27d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

`/gemini:setup` installs them with `agy plugin install <plugin-root>/agy`, landing in `~/.gemini/config/plugins/gemini-agents/`. The agy-side plugin deliberately ships agents only — including `commands/` would make agy c

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What This Is

A Claude Code plugin marketplace that reaches Gemini through the Antigravity CLI (agy). Two plugins share the same Google OAuth credentials:

  • gemini — slash commands for code review, ask, adversarial review, and implementation. Pure Markdown commands + agent definitions, no JS runtime. Everything is read-only except /gemini:implement, which edits files.
  • gemini-images — PreToolUse hook that replaces image Read calls with Gemini-generated text descriptions, protecting Anthropic's prompt cache.

Everything user-facing stays in Claude Code. agy is only the backend that runs Gemini — the plugins are not installed into agy as skills.

CONTEXT.md is this repo's glossary — read it before writing or reviewing anything eval-related, since it fixes terms (e.g. "recall point" vs. "fabrication gate") that are easy to conflate otherwise.

Architecture

Marketplace registry at /.claude-plugin/marketplace.json points at two plugin sources under /plugins/:

.claude-plugin/marketplace.json          # marketplace registry (2 plugins)
plugins/gemini/
  .claude-plugin/plugin.json             # also registers the SessionStart hook
  commands/                              # /gemini:setup, review, ask, adversarial-review, implement
  hooks/check-agent-version.sh           # warns when agy's agents drift from what the plugin ships
  agy/plugin.json                        # agy-side plugin — agents only, no commands
  agy/agents/<name>/agent.md             # system prompts, installed via `agy plugin install`
  README.md
plugins/gemini-images/
  .claude-plugin/plugin.json             # registers PreToolUse hook on Read
  hooks/intercept-image-read.sh          # entry point
  hooks/image-describe.mjs               # resize + agy describe + parallel tesseract OCR

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
