PostToolUse

PostToolUse is a hook for Claude Code from mikeparcewski/wicked-garden. Its token cost is not measured, scanned A, original, MIT.

A post-tool hook that runs a Python script after selected Claude Code actions, such as creating or updating tasks, editing files, reading, searching, or running shell commands.

In plain words
What is it for?
Use it to trigger invoke.py after the listed tool calls, with different timeouts and asynchronous behavior depending on the action.
Why use it?
It provides a consistent follow-up action after those tools finish without requiring each workflow to invoke the script separately.

Hook for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: names the TodoWrite tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the wicked-garden plugin — 148 skills, 5 commands, 1 agent, 13 hooks shipped together

One of 12 entries in hooks.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

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 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.
