assay

A Claude Code plug-in that connects the coding agent to Assay, a service providing policy checks and evidence-related tools. It also includes guidance for following Assay's recommended workflow.

In plain words
What is it for?
It is for applying policy checks, collecting or reviewing supporting evidence, and following Assay's documented coding workflow.
Why use it?
It gives Claude Code access to Assay's policy and evidence checks instead of leaving those checks outside the coding session.

Security

Grade A, and why

assay 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.

This is a copy

86% identical to assay marketplace — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
