FAQPage Schema
How do I detect scope drift in a feature branch before merging?▼

You can detect scope drift by running a diff-based pre-landing review on your current branch against the base branch. This flags structural issues, missing requirements, and deliverable misalignment that automated tests often miss.

What is a pre-landing PR review and how does it differ from automated testing?▼

A pre-landing PR review evaluates structural issues and deliverable alignment using branch diffs, whereas automated testing validates code execution. The review classifies findings into statuses like DONE, BLOCKED, or NEEDS_CONTEXT for actionable resolution.

How do I generate a structured review report for my pull request?▼

Generate a structured review report by running the review workflow on your current local branch. It compares your changes against the base branch and outputs a GSTACK summary with actionable items to speed up safe merging.

Can I automate PR quality checks using local git state?▼

Yes, PR quality checks can be automated using your local git state. The review process applies diff analysis against the base branch to identify pre-landing blockers and log telemetry without needing external test runners.

Does pre-landing review work without external dependencies or test suites?▼

Pre-landing review works without external dependencies by relying on local git state and plan-mode tooling. It classifies structural findings internally, meaning no additional test suites or external libraries are required to flag missing requirements.

Why are structural issues missed by tests flagged during a diff review?▼

Structural issues are missed by tests because tests validate execution behavior, not deliverable alignment. A diff review analyzes the branch changes against base requirements, classifying findings as BLOCKED or NEEDS_CONTEXT to catch these gaps.
