pre-commit hook
One of the Git client hook mechanisms, triggered after git commit executes and before the commit object is created. A script exiting with a non-zero status code aborts the commit. It is commonly used for format checks, secret scanning, and AI review.

Hooking lint_secrets.py into a pre-commit hook or CI means that whether a human or an agent commits, this rule takes effect automatically, without relying on either party's memory.
Geoffrey Huntley proposed using pre-commit Git hooks to force AI coding agents to comply with specifications, rather than repeatedly modifying the prompt or AGENTS.md.
Huntley claims that the pre-commit hook interception mechanism made the agent's performance instantly reach a perfect score ('All of a sudden it's ten out of ten.').
The pattern of writing constraints as pre-commit hooks can be transferred to many scenarios, such as enforcing the use of a unified logging module, prohibiting direct reading of environment variables, and prohibiting the introduction of certain types of dependencies in specific directories, as long as the constraints can be written as static checks.
