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 9d 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.
This is a copy
80% identical to PreToolUse — 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.

UserPromptExpansion is a hook published in the GitHub repository shanraisshan/claude-code-hooks (539 stars, last pushed 3mo ago), licensed MIT.

It is 80% identical to PreToolUse, differing in 4 lines, and is treated as a copy.
Other hooks, from other repositories
SessionStart
Runs when a session starts, running an inline shell check. From stempeck/agentfactory.
PreToolUse
Runs before the agent uses a tool for Bash, Write and Edit tool calls, running an inline shell check. From stempeck/agentfactory.
PreCompact
Runs before the context is compacted, running an inline shell check. From stempeck/agentfactory.
UserPromptSubmit
Runs when you submit a prompt, before the agent sees it, running an inline shell check. From stempeck/agentfactory.
PreToolUse
Runs before the agent uses a tool for Write, Edit, MultiEdit, Agent and Skill tool calls, executing gate-write.sh, record-agent-dispatch.sh and record-skill.sh (3 commands). From taipt1504/claudehut.
UserPromptExpansion
Runs to expand your prompt before the agent sees it for (claudehut:)?(implement, discover and brainstorm) tool calls, executing record-skill-expansion.sh. From taipt1504/claudehut.
