Security

Grade A, and why

awesome-agent-skills 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 5d ago.

The scan reads gemini-extension.json. This mod also ships 2 executable files (scripts/install-hooks.py, scripts/lint.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": "awesome-agent-skills",
  "version": "1.17.0",
  "description": "Skills for AI coding agents: code review, test writing, design docs, debugging, security and dependency audits, git history surgery, refactoring, copywriting, and cleaning up AI-written code and text. Every skill is a plain SKILL.md folder under the open Agent Skills standard, stack-agnostic, and ends with the check that proves its claim."

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.

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.
