PostToolUse

PostToolUse is a hook for Claude Code from voxpelli/vp-claude. Its token cost is not measured, scanned A, original, MIT.

An automatic follow-up hook that runs shell scripts after selected note or file-edit operations finish. A hook is an action triggered by a particular event.

In plain words
What is it for?
Validating Basic Memory notes after they are written or edited, and running a follow-up script after Edit or Write operations.
Why use it?
It can validate changed notes and perform follow-up work after files are edited, reducing the need to remember those checks manually.

Hook for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable.

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 vp-knowledge plugin — 14 skills, 5 agents, 4 hooks shipped together

One of 4 entries in hooks.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 6d 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.

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.
