open-plugins

An open-source marketplace for Claude Code plugins, which are add-ons that extend an AI coding assistant. It lists plugins for software-development processes, skill management, and related tasks.

In plain words
What is it for?
Use it to discover, publish, and manage Claude Code plugins such as software-lifecycle tools and skill-management utilities.
Why use it?
It gives developers one place to find and organize add-ons instead of searching through separate projects. The marketplace also records each plugin's source, category, and version.

Plugin for Claude Code

Getting it into your agent

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.

npx agentmods add plugins/baodq97/open-plugin/marketplace
Clone the repo
git clone --depth 1 https://github.com/baodq97/open-plugin

Security

Grade A, and why

open-plugins 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 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.

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 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.
