claude-code-best-practice-zh: Hook for Claude Code

.claude/settings.json

UserPromptSubmit is a hook for Claude Code from Rito-w/claude-code-best-practice-zh. Its token cost is not measured, scanned A, a copy of PreToolUse, MIT.

A prompt-submission hook that runs a Python script before the agent receives your prompt. A hook is an automatic action tied to a specific event.

In plain words
What is it for?
It is for running the project's hooks.py script whenever a user submits a prompt, in the background with a five-second timeout.
Why use it?
It allows the project to process or inspect submitted prompts automatically before work begins.

Hook for Claude Code

Written for Claude Code: ${CLAUDE_PROJECT_DIR} variable.

This is Rito-w/claude-code-best-practice-zh's own configuration. It tells Claude Code how to work on claude-code-best-practice-zh itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-code-best-practice-zh configures →

One of 31 entries in settings.json — they are configured in one file and arrive together.

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 6d 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

83% 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.
