PostToolUse

PostToolUse is a hook for Claude Code from DanceNitra/inspeximus. Its token cost is not measured, scanned A, original, MIT.

A session hook that runs a specified command after another tool call finishes. In this configuration, it runs an inspeximus Python module through uvx.

In plain words
What is it for?
Use it to run the configured inspeximus command after each completed tool call.
Why use it?
It automates a follow-up check or action after tool use instead of relying on someone to run it manually.

Hook for Claude Code

Written for Claude Code: PostToolUse hook event.

Part of the inspeximus plugin — 5 hooks, 1 MCP server shipped together

One of 5 entries in hooks.json upstream. Installing this one merges just its entry into your config; the other 4 are separate, each on its own page.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Or install inspeximus, the plugin that ships this one along with the rest of its 5 hooks, 1 MCP server.

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.
