GENesis-AGI: Hook for Claude Code

.claude/settings.json

PreToolUse is a hook for Claude Code from WingedGuardian/GENesis-AGI. Its token cost is not measured, scanned A, a copy of SessionStart, MIT.

A set of automatic actions that runs before the coding agent uses tools such as reading files, running commands, editing files, searching the web, or managing worktrees.

In plain words
What is it for?
Use it to enforce procedures, control discovery and background processes, and inspect tool calls before execution.
Why use it?
It can apply project checks and block unsafe or disallowed operations before they happen.

Hook for Claude Code

Written for Claude Code: ${CLAUDE_PROJECT_DIR} variable. Also seen: names the NotebookEdit tool.

This is WingedGuardian/GENesis-AGI's own configuration. It tells Claude Code how to work on GENesis-AGI 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 GENesis-AGI configures →

One of 9 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 8 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 7d 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

42% identical to SessionStart — 315 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.
