What problem does it solve? Implementation work often drifts beyond its intended boundary, causing cross-domain contamination that breaks unrelated features. This Skill enforces the rule "fix one page, don't touch others" by declaring an allowed file set before coding and verifying the actual git diff against it afterward. ## Core Features & Use Cases - Scope Declaration: Maps a feature name (e.g., "attribution portal", "booking checkout") to canonical primary and shared file paths using built-in domain maps for a Django backend and Next.js frontend. - Blast-Radius Audit: Classifies every changed file from git diff as in-scope, shared, violation, or informational, then produces a structured pass/fail report. - Violation & Shared-File Protocols: Offers revert, separate-branch, or justify-in-place options for violations, and evaluates shared-file touches as interface-only, logic change, or incidental. - Pre-Commit Gate: Runs as a pre-commit hook that infers scope from the branch name and blocks commits containing out-of-scope changes. - Use Case: Before committing a checkout fix, run a scope check to discover you accidentally modified a provider profile component, then revert it or move it to a separate PR. ## Quick Start Ask the AI to declare scope for the attribution portal feature, then after implementing run a scope check against the current git diff.
