agentskel

agentskel is a plugin for Gemini CLI from ahmadulhoq/agentskel. Its token cost is not measured, scanned A, original, MIT.

An extension that gives an AI coding agent persistent project memory, shared team standards, and structured workflows. When installed for Gemini, it loads `GEMINI.md` as context, meaning background information supplied to the agent.

In plain words
What is it for?
Use it to provide an AI coding agent with project memory, team rules, workflow files, and related setup files.
Why use it?
It keeps important project guidance available across coding sessions instead of relying on the agent to rediscover it each time.

Security

Grade A, and why

agentskel 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 25d ago.

The scan reads gemini-extension.json. This mod also ships 2 executable files (scripts/install-agent.sh, scripts/validate.py), 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.

What it actually says

{
  "name": "agentskel",
  "description": "Persistent memory, shared team standards, and structured workflows for AI coding agents. When installed as a Gemini extension, GEMINI.md is loaded as context. To get full per-project install (memory branch, rules, hooks, .agents/, .gemini/skills/), ask Gemini to run the `setup-skeleton` workflow in your project directory.",

Files

What ships with it

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.

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.
