dotfiles: Hook for Claude Code

.claude/settings.json

PreToolUse is a hook for Claude Code from connorads/dotfiles. Its token cost is not measured, scanned A, original, no licence file.

A pre-tool hook that runs checks before Bash tool calls. It uses Python and runs scripts for attribution, API changes, local curls, protection bypasses, package-manager choices, secret paths, and agent state.

In plain words
What is it for?
It helps enforce command-safety and project conventions in Bash-based agent workflows.
Why use it?
It adds automated checks before commands run, helping catch unsafe or unwanted actions early. The input does not describe the exact rules in each script.

Hook for Claude Code

Written for Claude Code: installed under .claude/.

This is connorads/dotfiles's own configuration. It tells Claude Code how to work on dotfiles 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 dotfiles configures →

One of 11 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 10 are separate, each on its own page.

Security

Grade A, and why

PreToolUse scanned grade A with 1 finding 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
