claudekit: Hook for Claude Code

.claude/settings.json

SubagentStop is a hook for Claude Code from carlrannaberg/claudekit. Its token cost is not measured, scanned A, a copy of Stop, MIT.

An automatic check that runs when a subagent, or helper coding agent, finishes its work. It runs project type checks, linting, tests, and a self-review.

In plain words
What is it for?
Use it to automatically type-check, lint, test, and review changes after a subagent stops.
Why use it?
It catches common code and quality problems before the finished work is handed back. This gives every completed subagent task the same verification steps.

Hook for Claude Code

Written for Claude Code: SubagentStop hook event.

This is carlrannaberg/claudekit's own configuration. It tells Claude Code how to work on claudekit 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 claudekit 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 A, and why

SubagentStop 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 11d 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

91% identical to Stop — 10 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.

Changes

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.
