venutian-antfarm: Hook for Claude Code

.claude/settings.json

PreToolUse is a hook for Claude Code from RD-DCS/venutian-antfarm. Its token cost is not measured, scanned B, original, no licence file.

A pre-tool hook that runs before Edit, Write, or Bash commands and executes a metrics logging script.

In plain words
What is it for?
Use it to log metrics whenever an agent edits files, writes files, or runs shell commands.
Why use it?
It records metrics before those actions take place.

Hook for Claude Code

Written for Claude Code: installed under .claude/.

This is RD-DCS/venutian-antfarm's own configuration. It tells Claude Code how to work on venutian-antfarm 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 venutian-antfarm configures →

One of 6 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 5 are separate, each on its own page.

Security

Grade B, and why

PreToolUse scanned grade B 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 9d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What else settings.json configures

This page is one entry in a file that holds 6. Installing the file brings all of them; each is measured and scanned on its own page.

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.

Its token cost is not measured: a hook is shell that never enters the context. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
