Code Review: Recent Changes

Review the diff between HEAD and a fixed point the user supplies, along three independent axes:

• Standards - does the code conform to this repo's documented conventions?
• Spec - does the code faithfully implement the originating issue / PRD / spec?
• Maintainability - is the change structurally healthy, or did it leave the codebase harder to change?

Each axis runs as its own parallel sub-agent so they don't pollute each other's context, then this skill aggregates their findings. Keep them separate: a change can pass one axis and fail another - code that follows every convention but implements the wrong thing (Standards pass, Spec fail), or does exactly what the issue asked while leaving the codebase messier (Spec pass, Maintainability fail). Separate reporting stops one axis from masking another.

Review stance

Two ideas shape how the sub-agents work, so build them into the briefs:

• Read outward from the diff. An agent handed a diff tends to treat it as the edge of the world. Tell each sub-agent to look past it: for a changed symbol, read its surrounding function/file and the modules that call it or that it calls. A hunk that looks fine in isolation can duplicate an existing helper, contradict a sibling module's pattern, or leave a half-finished migration two files over.
• Be ambitious on Maintainability; precise on Standards and Spec. Standards and Spec are close to binary - a documented rule is violated or it isn't, a requirement is met or it isn't - so favour precision and don't manufacture findings. Maintainability is where the valuable, easy-to-miss findings live, so favour recall: propose a restructuring even when you're not fully sure, because a wrong suggestion costs the reader one quick "no", while a worthwhile one you never raise is one nobody gets to consider. To keep the wrong ones cheap to dismiss, every Maintainability finding carries a confidence label and concrete evidence.
