GoKawiilImpactGate launches as open-source CI tool to block AI-driven code decay
ImpactGate is a new open-source tool that scores code changes for structural decay before they merge, running as a CLI, git pre-commit hook, or CI plugin for GitHub, GitLab, and Jenkins. It calculates an impact score based on files changed, existing complexity in the code being touched, cyclomatic complexity, and lines changed, making edits to already-bloated classes costlier than new additions.
GoKawiil's interpretation of the reporting above, not reported fact.
As AI coding assistants generate more commits, codebases risk quietly accumulating complexity in already-overloaded classes and methods, a problem traditional linters and test coverage tools don't catch. By gating merges on a quantifiable decay score rather than just style or bugs, teams get an automated checkpoint to catch when a change is expanding technical debt rather than fixing it, potentially reshaping how code review handles AI-generated contributions.
- ImpactGate scores changes using a formula combining files changed, existing method/class complexity, cyclomatic complexity, and lines altered.
- It can run as a standalone CLI, pre-commit hook, or CI plugin, and supports warn-only or build-blocking enforcement modes.
- New files or classes score cheaply while additions to already-complex code score expensively, directly targeting the kind of sprawl AI-assisted coding can introduce.
