Notification

A hook that runs an inline shell check when the agent sends a notification. A hook is an automatic action tied to an event in the agent's work.

In plain words
What is it for?
Use it to run a shell-based check whenever the agent produces a notification.
Why use it?
It lets a project check something at the moment a notification is sent, without requiring a separate manual step.

Grade A, and why

Notification 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 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.

Expected in a hook, worth knowing in a rule or an instructions file.

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.
