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.

jest-coverage-mutation 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 10d 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 it actually says
{
"name": "jest-coverage-mutation",
"displayName": "Jest Coverage & Mutation Testing",
"version": "0.10.0",
"description": "Measure how good your unit tests actually are — set up Jest code coverage, then Stryker mutation testing to prove the tests catch real bugs (not just execute lines). Interpret mutation score, kill survived mutants, and gate CI on both. Enforces guardrails against coverage theater: no assertion-free tests, no gaming the score by excluding mutators or files, every fix must kill a specific survived mutant, mutation is scoped to high-risk logic (changed-code on PRs, full run nightly), and CI is gated on a Stryker break threshold — not coverage % alone.",

What it installs
The manifest is a name and a version. 1 skill, 1 agent travel with it, and installing the plugin installs all of them — 195 tokens a session between them. Each is measured on its own page, and each can be installed alone.
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.
