UserPromptSubmit

UserPromptSubmit is a hook for Claude Code from younnieCutler/japan-career-agent. Its token cost is not measured, scanned A, original, MIT.

A prompt-submission hook that runs a status script before the coding agent sees your request. It can show whether the career workflow's checks and deadlines were available.

In plain words
What is it for?
It is for displaying career-workflow status at the start of each submitted prompt, with fallback messages when the script or Python is unavailable.
Why use it?
It gives an early status message when required career checks cannot run, instead of leaving that problem unclear.

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.

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 11d 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.

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.
