claudepot-app: Hook for Claude Code

.claude/settings.json

PreToolUse is a hook for Claude Code from xiaolai/claudepot-app. Its token cost is not measured, scanned A, original, ISC.

A pre-action security check that runs before a coding agent uses the Bash command tool. It looks for certain secret patterns in staged files when the command is trying to create a Git commit.

In plain words
What is it for?
For checking staged files before Git commits and stopping commits that contain the listed Claude credentials or other sensitive command text.
Why use it?
It helps prevent API keys, access tokens, or keychain passwords from being committed to the repository. A matching secret blocks the commit.

Hook for Claude Code

Written for Claude Code: PreToolUse hook event.

This is xiaolai/claudepot-app's own configuration. It tells Claude Code how to work on claudepot-app 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 claudepot-app configures →

One of 2 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 1 are separate, each on its own page.

Security

Grade A, and why

PreToolUse 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 2mo 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.
