epistemic-cooperative

epistemic-cooperative is a plugin for Claude Code from jongwony/epistemic-protocols. Its manifest loads nothing; the 13 skills it bundles cost 507 tokens per session together, scanned A, original, MIT.

A collection of utility skills built on shared core protocols, with a catalog command for browsing their handbook and each skill defining its own rules.

In plain words
What is it for?
It helps browse protocol documentation and apply individual utility skills according to their own instructions.
Why use it?
It gives an agent a consistent way to discover and use small, contract-based utilities without keeping every instruction in one place.

Security

Grade A, and why

epistemic-cooperative 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.
