Stop

Stop is a hook for Claude Code from skynetcmd/m3-memory. Its token cost is not measured, scanned A, a copy of PreCompact, Apache-2.0.

A hook that runs a shell check after the agent finishes replying.

In plain words
What is it for?
Use it to trigger end-of-response chat-log handling asynchronously.
Why use it?
It lets the memory system record the conversation when its command-line tool is available, without failing when it is not installed.

Hook for Claude Code

Written for Claude Code: shipped in a Claude Code plugin. Also seen: mentions Codex.

Part of the m3 plugin — 16 skills, 15 commands, 2 agents, 3 hooks, 2 MCP servers shipped together

One of 3 entries in hooks.json upstream. Installing this one merges just its entry into your config; the other 2 are separate, each on its own page.

Good fit Use it to trigger end-of-response chat-log handling asynchronously.

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.

Security

Grade A, and why

Stop 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

92% identical to PreCompact — 3 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.
