fundamental-ngx: Hook for Claude Code

.claude/settings.json

PreToolUse is a hook for Claude Code from SAP/fundamental-ngx. Its token cost is not measured, scanned A, original, Apache-2.0.

A set of checks that runs before an agent uses search or file-reading tools. It calls graphify's guard commands for shell searches, text searches, file reads, and file searches.

In plain words
What is it for?
Use it as a pre-tool hook for Bash, Grep, Read, and Glob calls in an agent setup.
Why use it?
It can check these actions before they happen, helping enforce the configured workflow for inspecting a project. The input does not say what decisions the guard makes.

Written for Claude Code: PreToolUse hook event.

This is SAP/fundamental-ngx's own configuration. It tells Claude Code how to work on fundamental-ngx 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 fundamental-ngx 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 8d 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.
