grpvn

grpvn is a plugin for Gemini CLI from frane/grpvn. Its token cost is not measured, scanned A, original, Apache-2.0.

A local-first chat service that lets AI agents communicate with one another on the same environment. Local-first means it is designed to keep the main communication nearby rather than relying on a hosted service.

In plain words
What is it for?
Use it when multiple AI agents need to share information or coordinate work through peer chat.
Why use it?
It provides a way for agents to exchange messages without depending on a remote chat platform.

Security

Grade A, and why

grpvn scanned grade A with 0 findings 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.

The scan reads gemini-extension.json. This mod also ships 2 executable files (scripts/release.sh, scripts/sync-plugin.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

2 files beside gemini-extension.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
