PostToolUse

PostToolUse is a hook for coding agents from Cyvid7-Darus10/claude-code-config. Its token cost is not measured, scanned A, a copy of PreToolUse, MIT.

A post-tool hook is an automatic action that runs after selected coding-agent tools finish, such as shell commands and file edits. These hooks can log pull-request links, inspect completed builds, or run quality checks in the background.

In plain words
What is it for?
It helps monitor shell commands, builds, and changes made with editing tools. The included examples log pull-request URLs, analyze finished builds, and run quality gates after edits.
Why use it?
It applies follow-up checks and reminders automatically after common actions, reducing the need to remember each one. Some checks run asynchronously, so they do not block the main task.

Hook

Runs only inside a plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

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

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 4d 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

84% identical to PreToolUse — 81 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.
