What problem does it solve? When triaging issue reports, a diagnosed code path that explains a symptom is not automatically a bug. This Skill prevents wasted fix work by gating the fix stage: it cross-references code, comments, documentation, and tests to decide whether the behavior is a genuine defect, intentional design, or genuinely ambiguous. ## Core Features & Use Cases - Three-verdict classification: Returns exactly one of bug, intended-behavior, or unclear, each with cited reasoning pointing to specific comments, docs, or tests. - Evidence-based cross-referencing: Reads surrounding code, docstrings, AGENTS.md, CONTRIBUTING.md, docs/, and existing tests to establish documented intent before judging. - Read-only safety: Enforces hard prohibitions on source edits, commits, pushes, and external network calls, so verification never mutates the repository. - Use Case: A reporter claims the API should return a bare array, but the code returns { items, nextCursor }. The Skill finds the pagination contract documented in AGENTS.md, returns intended-behavior, and drafts a comment pointing the reporter to the docs. ## Quick Start Ask the agent to verify whether the diagnosed behavior in the current issue is a bug or intended behavior, citing the relevant docs and tests.
