PostToolUse

PostToolUse is a hook for Claude Code from H-mmer/pentest-agents. Its token cost is not measured, scanned A, original, no licence file.

A check that runs after a Bash command finishes. Bash is a tool for running shell commands.

In plain words
What is it for?
It is for applying a cost check after Bash commands used during a security assessment.
Why use it?
It records the cost of completed shell-command work, giving the security workflow a way to track resource use.

Security

Grade A, and why

PostToolUse scanned grade A with 1 finding 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.

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.
