SubagentStop

A hook that runs commands when certain Superloopy helper agents finish. A hook is an automatic action triggered by an event, and Superloopy is the system that provides those agents.

In plain words
What is it for?
Use it to trigger the configured stop and audit commands after the listed Superloopy agents finish.
Why use it?
It automates follow-up checks after selected agents stop, so completion handling does not depend on someone remembering to run the commands.

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.

Or install superloopy, the plugin that ships this one along with the rest of its 9 skills, 6 agents, 4 hooks.

Grade A, and why

SubagentStop 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 3d ago.

A static scan of the commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

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.
