UserPromptSubmit

UserPromptSubmit is a hook for Claude Code from oliver-kriska/claude-elixir-phoenix. Its token cost is not measured, scanned A, original, MIT.

An automatic command that runs when you submit a prompt, before the agent reads it, to route the request's intent.

In plain words
What is it for?
Running route-intent.sh on each submitted prompt to classify or route the request.
Why use it?
It can perform an initial routing step before the agent processes your request.

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 phx plugin — 50 skills, 26 agents, 10 hooks shipped together

One of 10 entries in hooks.json upstream. Installing this one merges just its entry into your config; the other 9 are separate, each on its own page.

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.

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.
