UserPromptSubmit

UserPromptSubmit is a hook for Claude Code from sushichan044/cc-hooks-ts. Its token cost is not measured, scanned A, a copy of PreToolUse, MIT.

A prompt-submission hook that runs a Node.js script whenever a user sends a prompt. A hook is an automatic command triggered by a specific event.

In plain words
What is it for?
It runs `scripts/log-hook-event.ts` with the `UserPromptSubmit` event before the agent processes the prompt.
Why use it?
It provides a place to record or handle prompt submissions automatically, without requiring the agent to run the script manually.

Security

Grade A, and why

UserPromptSubmit 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 6d 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

80% identical to PreToolUse — 4 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.
