claude-code-onboarding: Hook for Claude Code

.claude/settings.json

PostToolUse is a hook for Claude Code from kumaran-is/claude-code-onboarding. Its token cost is not measured, scanned A, a copy of SessionStart, MIT.

A set of checks that runs after the coding agent uses tools such as editing files or running commands.

In plain words
What is it for?
Use it after file edits, Bash commands, reads, or web requests to format code and run type, secret, pattern, and dead-code checks.
Why use it?
It checks changed code for formatting, type errors, exposed secrets, unwanted AI patterns, and unused code after the work is done.

Hook for Claude Code

Written for Claude Code: $CLAUDE_PROJECT_DIR variable.

This is kumaran-is/claude-code-onboarding's own configuration. It tells Claude Code how to work on claude-code-onboarding 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 claude-code-onboarding configures →

One of 7 entries in settings.json — they are configured in one file and arrive together.

Security

Grade A, and why

PostToolUse 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 3d 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

48% identical to SessionStart — 118 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.
