What it does and how to use it

A hook that automates automation actions at key moments (before/after a tool runs, on save, etc.), without you having to think about it.

Install the hook (command above).
It runs automatically on the defined events.
Adjust the rules in the settings file if you want to fine-tune it.

Install (Claude Code)

mkdir -p .claude/hooks && curl -fsSL https://doutorai.pt/data/lib/hooks__slack-detailed-notifications.md -o .claude/hooks/slack-detailed-notifications.json

Paste this command into the terminal, in your project folder, and the component installs automatically.
