What problem does it solve? Code reviews often miss cases where contributors rebuild functionality that already exists in the codebase, leading to duplicated abstractions and maintenance burden. This Skill runs a predefined tripwire review against a diff or the current branch to flag such reinventions consistently. ## Core Features & Use Cases - Authoritative Review Definition: Reads the review rules from .ns/reviews/reinvented-abstractions-tripwire/review.md instead of relying on memory, ensuring consistent application. - CLI Integration: Prefers running through the ns reviews review run reinvented-abstractions-tripwire command when available inside the repository. - Read-Only Inline Review: When run inline, applies the review definition exactly to the supplied diff or current branch changes while staying read-only. - Use Case: Before merging a pull request, run this tripwire against the branch diff to catch newly introduced helpers or wrappers that duplicate existing abstractions. ## Quick Start Ask the agent to run the reinvented abstractions tripwire review against the current branch changes.
