SubagentStop

SubagentStop is a hook for coding agents from openJiuwen-ai/agent-memory. Its token cost is not measured, scanned A, a copy of SubagentStop, Apache-2.0.

A command hook that runs a Node.js script when a subagent finishes. A subagent is a smaller AI worker handling part of a larger task.

In plain words
What is it for?
It runs the project’s subagent-stop.mjs script after each subagent finishes. The provided details do not say what that script does.
Why use it?
It lets the main agent automatically react when that worker is done, without requiring a manual step.

Hook

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the jiuwen_memory plugin — 2 commands, 12 hooks shipped together

One of 12 entries in hooks.json — they are configured in one file and arrive together.

Install

Getting it into your agent

This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Claude Code
/plugin marketplace add openJiuwen-ai/agent-memory
Claude Code
/plugin install jiuwen_memory

Or install jiuwen_memory, the plugin that ships this one along with the rest of its 2 commands, 12 hooks.

Security

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 4d 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.

Origin

This is a copy

100% identical to SubagentStop — 0 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.
