What is arcblock-agent-skills marketplace?

A marketplace collection of seven ArcBlock plugins, including tools for Blocklet projects, plugin development, reasoning frameworks, context, and content creation. ArcBlock is a platform whose Blocklets are packaged web applications.

Use it to discover the listed ArcBlock plugins, especially for converting web projects to Blocklets, managing releases, developing plugins, or working with the collection's other listed skills.

It gives developers one catalogue entry for several related add-ons instead of finding each plugin separately. The provided description does not explain the detailed behaviour of every plugin.

Security

Grade A, and why

arcblock-agent-skills marketplace 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.

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.
