kendex: Hook for Claude Code

.claude/settings.json

PreToolUse is a hook for Claude Code from vanillagreencom/kendex. Its token cost is not measured, scanned A, a copy of SessionStart, MIT.

Commands that run automatically before the coding agent uses Bash, the command-line tool for running shell commands.

In plain words
What is it for?
Applying project checks and safety restrictions to every Bash tool call.
Why use it?
They catch or block unsafe actions before they happen, such as bare directory changes, invalid commits, repository copies, or unsafe file removal.

Hook for Claude Code

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

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

One of 12 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 11 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 10d 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

47% identical to SessionStart — 65 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.

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.
