Claude-Code-Game-Studios: Hook for Claude Code

.claude/settings.json

PreToolUse is a hook for Claude Code from Donchitos/Claude-Code-Game-Studios. Its token cost is not measured, scanned A, original, MIT.

A pre-action hook that runs shell scripts before the agent uses Bash. Shell scripts are small command-line programs that automate checks or other tasks.

In plain words
What is it for?
Use it in projects that need checks before creating commits or sending changes to a remote code repository.
Why use it?
It can check whether commit and push actions meet project rules before those commands run. The supplied details do not say what the checks themselves validate.

Hook for Claude Code

Written for Claude Code: $CLAUDE_PROJECT_DIR variable.

This is Donchitos/Claude-Code-Game-Studios's own configuration. It tells Claude Code how to work on Claude-Code-Game-Studios 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-Game-Studios configures →

One of 10 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 9 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 18d 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.
