horizon67 Reviewing Changes
The purpose of a review is to find problems introduced by a change before merge and explain them in a form the author can act on. Do not optimize for the number of findings. Unless the user requests a broader audit, exclude matters of taste, unsupported concerns, and pre-existing problems unrelated to the change.
Understand the review scope
Establish the review target, comparison base, and expected behavior from the request and available repository context. If the base is unspecified, use a reasonable scope from the current branch or working tree and state it; ask only when materially different interpretations remain.
Inspect surrounding code, callers, requirements, and tests where needed to understand an affected path. For a design review, focus on assumptions, responsibility boundaries, failure behavior, and compatibility relevant to the proposal.
Verify problems
Prioritize concrete correctness, security, data integrity, compatibility, concurrency, or performance failures on affected paths. Missing tests alone are not a defect; explain the behavior at risk or the explicit testing requirement that is unmet.
Support each candidate with an execution path, established requirement, or focused test. Run checks when they resolve a concrete uncertainty, rather than requiring a test for every finding. Separate unresolved questions from confirmed defects, and do not invent findings to fill a checklist.
Write findings
Write one finding for each independent problem. Order findings by severity and use these priorities:
P0: Stop immediately. The change can cause a widespread outage, major information disclosure, or data loss that is difficult to recover from.P1: Fix before merge. A common path can cause a severe failure or security issue.P2: Normal priority. Specific conditions cause incorrect behavior or a material maintenance problem.P3: Low impact but worth fixing to prevent a concrete defect or future problem.
Explain each finding's trigger, incorrect behavior, impact, and evidence, with a concise title and a remediation direction when known. For code reviews, cite the smallest useful line range and attach it to a changed line when possible. Use the format requested by the user or review tool; a separate template is unnecessary.
Lead the final review with findings or an explicit statement that none were found. Mention material coverage limits or unresolved questions. A change summary alone is not a completed review.
Changes and external operations
A review request alone does not authorize code changes. Modify and validate code only when the user explicitly requests fixes.
Submit a GitHub review, comment, approve, request changes, or resolve a conversation only when the user explicitly asks. When posting is requested, keep the GitHub review consistent with the findings reported in the conversation.
