What problem does it solve? After an implementation pass, a single agent often misses bugs, scope creep, unrequested refactors, or contract drift in its own diff. This Skill adds an independent second-agent review pass that inspects staged or branch changes read-only and reports findings before a task or pull request is finalized. ## Core Features & Use Cases - Independent Diff Review: Delegates review of staged or branch diffs to a separate agent operating in a read-only, code-review stance. - Scope and Policy Checks: Verifies the diff against accepted change categories, review-policy gates, production-use evidence rules, and documentation authority classes. - Structured Findings Output: Returns findings ordered by severity with file and line references, plus a mandatory Diff minimality section separating required from unrequested structural changes. - Use Case: After implementing a public API change, the primary agent stages the diff, invokes this Skill to have a second agent audit it for contract drift, missing tests, and unrequested refactors, then triages each finding as accepted, rejected, or deferred before opening the pull request. ## Quick Start Use $second-agent-review to run an independent read-only review of the current staged changes.
