Git hook
A script that Git executes before or after events such as commit, push, and receive.

When to use it
Use a Git hook when you need to automate checks or actions tied to Git events like commits or pushes. Git hooks enable automated processes such as running tests, enforcing coding standards, or prompting developers to verify code logic, as seen in tasks like pre-commit linting or pre-push quizzes.
Quick example
In a project using Sphinx, a Git hook quizzes developers on AI code logic before they can push changes. This Git hook is configured to run a script that prompts developers with questions about the code's functionality, ensuring they understand the logic before deployment. Here, the Git hook acts as a safeguard, integrating directly with the Git workflow to enforce accountability.
commit → Git hook → quiz developers → push
Ecosystem
Git hooks operate within the Git workflow, directly interacting with stages like commit and push.
commit → Git hook → push
Misconceptions
| Misconception | Rebuttal |
|---|---|
| Git hooks are only for testing | They can automate any script tied to Git events |
| Hooks change Git's core behavior | They only add custom scripts, not alter Git itself |
Trade-offs
- Automation — requires maintaining scripts
- Consistency — can slow down the commit/push process
- Customization — scripts may become complex and brittle
