doughnut: Hook for Claude Code

.claude/settings.json

PostToolUse is a hook for Claude Code from nerds-odd-e/doughnut. Its token cost is not measured, scanned A, original, MIT.

A post-tool hook that runs a Node.js command after another tool call finishes. A hook is an automatic action attached to an agent event.

In plain words
What is it for?
Use it to run the shown CI host script after tool calls in a Claude project.
Why use it?
It lets an agent project perform a follow-up action without requiring a separate manual step.

Hook for Claude Code

Written for Claude Code: $CLAUDE_PROJECT_DIR variable.

This is nerds-odd-e/doughnut's own configuration. It tells Claude Code how to work on doughnut 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 doughnut configures →

One of 3 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 yesterday.

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.
