UserPromptExpansion

UserPromptExpansion is a hook for Claude Code from clomia/claude-automata. Its token cost is not measured, scanned A, a copy of SessionStart, Apache-2.0.

A hook that expands prompts before an agent receives three specific `ploop` commands: launch, off, and on. Hooks are automatic actions triggered when a matching command is used.

In plain words
What is it for?
Use it to start, pause, or resume the ploop workflow when those exact commands are called.
Why use it?
It adds the required shell-based setup or pause/resume action automatically, so the loop commands do not need manual preparation.

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 ploop plugin — 6 skills, 2 agents, 5 hooks 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.

Good fit Use it to start, pause, or resume the ploop workflow when those exact commands are called.

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 10d 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

59% identical to SessionStart — 38 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.

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.
