Code quality gate

What it means

A code quality gate evaluates configured checks such as new defects, security findings, coverage, duplication, or maintainability ratings. A gate turns quality policy into a repeatable decision, but its usefulness depends on scope, thresholds, and an explicit exception process. Gates should focus on changed code when legacy debt makes whole-repository blocking impractical.

Example

A team requires no new high-severity findings and a minimum test threshold on changed files. A migration can proceed with a documented exception that has an owner and expiry date.

Limitations

Poorly chosen gates create alert fatigue, encourage suppression, or block low-risk work for irrelevant findings. Passing a gate does not prove correctness, security, or maintainability. Review the policy as the system changes.

How to use the signal

Weave can help measure whether gate failures lead to useful fixes or merely extend review and queue time. Keep enforcement in CI and use Weave to evaluate the workflow effects of the policy.
