agenthub

A marketplace listing for 306 community-made Claude Code plugins. Claude Code plugins add specialized commands or capabilities to a coding assistant.

In plain words
What is it for?
Use it to discover plugins for jobs such as accessibility checks, software design, adversarial reviews, agent teams, and action auditing.
Why use it?
It gives developers one catalogue for finding add-ons, instead of searching through separate repositories for useful tools.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

agenthub scanned grade A 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 yesterday.

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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
