UserPromptSubmit

UserPromptSubmit is a hook for Claude Code from DanceNitra/inspeximus. Its token cost is not measured, scanned A, a copy of PostToolUse, MIT.

A hook that runs a command before an agent receives a submitted prompt.

In plain words
What is it for?
Use it as a prompt-submission trigger in Claude Code. The available details are not enough to describe its practical tasks.
Why use it?
It can inspect or process prompts at submission time, but the input does not explain what the command does or what problem it solves.

Hook for Claude Code

Written for Claude Code: UserPromptSubmit hook event.

Part of the inspeximus plugin — 5 hooks, 1 MCP server 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.

Getting it into your agent

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 yesterday.

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

88% identical to PostToolUse — 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.
