A-Team: Hook for Claude Code

.claude/settings.json

UserPromptSubmit is a hook for Claude Code from chemistrywow31/A-Team. Its token cost is not measured, scanned A, original, no licence file.

A prompt-submission hook that runs a shell check after you send a prompt but before the agent reads it.

In plain words
What is it for?
It is for running a fixed shell check on submitted prompts.
Why use it?
It allows an automatic check to happen before the agent processes your request.

Hook for Claude Code

Written for Claude Code: installed under .claude/.

This is chemistrywow31/A-Team's own configuration. It tells Claude Code how to work on A-Team 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 A-Team configures →

One of 5 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.

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.
