security-agent-skills

security-agent-skills is a plugin for Claude Code from UnboundCompute/security-agent-skills. Its manifest loads nothing; the 58 skills it bundles cost 9,771 tokens per session together, scanned A, original, MIT.

A collection of security-testing methods for software and infrastructure. It covers areas such as source-code bug hunting, AI-agent testing, cloud and CI/CD permissions, web and mobile applications, network protocols, authentication, access control, injections, file handling, and supply-chain risks.

In plain words
What is it for?
Use it for authorized security reviews of applications, agents, cloud systems, build pipelines, APIs, containers, mobile apps, smart contracts, dependencies, and infrastructure.
Why use it?
It provides focused ways to examine different trust boundaries and security failure modes instead of relying on a single general checklist.

Security

Grade A, and why

security-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 today.

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 installs

The manifest is a name and a version. 58 skills travel with it, and installing the plugin installs all of them — 9,771 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside plugin.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.
