Stop

Stop is a hook for Claude Code from es6kr/skills. Its token cost is not measured, scanned A, original, MIT.

A set of checks that runs when the coding agent finishes an answer. It uses shell scripts to inspect the session, tool calls, cleanup actions, and waiting behavior.

In plain words
What is it for?
Use it to enforce end-of-response rules, remove stale helper shells, validate cleanup prerequisites, and detect specific problems in the agent's final actions.
Why use it?
It helps catch malformed actions, unsafe cleanup, missing session context, and unnecessary waiting before the response is treated as finished.

Hook for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable.

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 es6kr plugin — 36 skills, 5 hooks shipped together

One of 5 entries in hooks.json upstream. Installing this one merges just its entry into your config; the other 4 are separate, each on its own page.

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 10d 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.

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.
