A plugin marketplace listing that groups 13 separate plugins, including tools for code checks, course planning, D3.js charts, and Google Workspace access. A marketplace listing describes available plugins; it is not itself one coding tool.

Use it to browse or distribute the included plugins, such as code-coherence, course-curriculum-creator, d3-visualizations, and Google Workspace integrations.

It gives users one place to discover and install related plugins instead of finding each plugin separately. The listed capabilities vary by plugin.

Security

Grade A, and why

cc-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 2d ago.

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.

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.
