PostToolUse

A group of automatic actions that runs after Write, Edit, Bash, or Agent tool calls. The actions compile code, track skill changes, and update a review-gate counter.

In plain words
What is it for?
Use it in an agent setup where file edits, shell commands, or sub-agent runs should trigger automatic compilation, change tracking, or review-gate updates. The input describes the hook rules but not the underlying scripts' detailed behavior.
Why use it?
It removes the need to remember these follow-up checks after every tool call. This helps keep generated code compiled and records activity that needs later review.

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.

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.

Origin

This is a copy

66% identical to SessionStart — 34 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.

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.
