UserPromptSubmit

UserPromptSubmit is a hook for Claude Code from Syedomershah99/being-human. Its token cost is not measured, scanned A, a copy of UserPromptSubmit, MIT.

A hook configuration that runs a command before an agent receives each submitted prompt. The command starts a Python script named capture.py from the plugin's directory.

In plain words
What is it for?
Use it to trigger capture.py on every user prompt in the Claude plugin environment.
Why use it?
It automates a step at prompt submission time, so the project can capture or process the incoming prompt before the agent works on it.

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 being-human plugin — 1 skill, 5 commands, 1 hook, 1 MCP server shipped together

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 8d 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

88% identical to UserPromptSubmit — 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.
