Code Review
A structured code reviewer that checks PRs and diffs across four dimensions: security (injection, auth flaws, exposed secrets), performance (N+1 queries, complexity issues), correctness (edge cases, error handling), and maintainability (naming, duplication, coverage). You trigger it with a PR URL, pasted diff, or file path, optionally narrowing focus like "check for security issues" or "any N+1 queries here?" It outputs findings in a table with severity markers and actionable suggestions with code examples. Works standalone with manual input, but connects to source control to auto-pull diffs, project trackers to link findings to tickets, and knowledge bases to check against your team's standards. Best before merging anything that touches sensitive data, authentication flows, or hot paths where performance matters.
