UserPromptExpansion

UserPromptExpansion is a hook for Claude Code from ryanzhao1011/workframe. Its token cost is not measured, scanned A, original, MIT.

A prompt-expansion hook that runs a logging script before the coding agent sees the user's prompt.

In plain words
What is it for?
Use it to automatically log skill-invocation information during prompt processing.
Why use it?
It records which skills are invoked while preparing the prompt, making skill use easier to track.

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 core plugin — 37 skills, 4 agents, 11 hooks shipped together

One of 11 entries in hooks.json — they are configured in one file and arrive together.

Security

Grade A, and why

UserPromptExpansion 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 5d 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.
