What problem does it solve? Large or incoherent changes often reach implementation before anyone checks whether they should be one pull request or several. This Skill runs an independent, read-only pre-implementation scope review so oversized plans are split or revised before code accumulates. ## Core Features & Use Cases - Scope Verdicts: Returns exactly one verdict — single_pr, split_required, or revise — based on repository hard gates, concern counts, and file-size limits. - Behavioral Decomposition: Maps every acceptance criterion to a proposed PR and checks that each slice stays useful and mergeable if later slices never land. - Dependency Liveness Checks: Simulates pre-merge, merge, validation, and activation transitions to detect dependency cycles or reliance on ambient work. - Use Case: Before implementing a feature spanning backend, frontend, and CI changes, delegate the plan to a fresh read-only subagent running this review to get an ordered, independently reviewable PR sequence. ## Quick Start Ask a fresh read-only subagent to use the implementation-scope-review skill on this issue and its acceptance criteria to return a scope verdict and proposed PR sequence before any files are edited.
