PostToolUse

PostToolUse is a hook for Claude Code from sifxprime/kodelyth-ecc. Its token cost is not measured, scanned A, a copy of PreToolUse, MIT.

Post-tool hooks are automatic scripts that run after the coding agent finishes actions such as editing files or running shell commands. They can track memory outcomes, remind you about tests, and record command activity.

In plain words
What is it for?
They help mark unresolved notes as failed when related files change, remind you to add tests after code edits, and audit shell commands.
Why use it?
They reduce the need to remember routine follow-up checks after changes and provide a record of shell commands.

Hook for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: reads .claude/ paths.

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 8 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.

Made for: Claude Code.

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 2d 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.

This is a copy

77% identical to PreToolUse — 151 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.
