Review code correctness and clarity in layers with Claude Code

Review correctness, clarity, performance, and style in order, and address severe findings before moving on.

Install in Claude Code

A Claude Code workspace with the code, its intended behavior, and a reproducible input before inspecting performance or style.

Review `.claude/skills/code-review/SKILL.md` and its requirements at the pinned GitHub commit.
Create `.claude/skills/code-review/` in your project and save the reviewed file as `.claude/skills/code-review/SKILL.md`.
Start Claude Code from that project's root, then select `/code-review` in the slash menu.

Example task

A fictional paginator uses zero-based pages. The request is `{page:0,limit:2,data:['hall','garden','loft'],actual:['garden','loft']}`. It should return the first two entries.

What to check

Lead with a correctness finding and expected `['hall','garden']`. Locate the offset error and add a page-zero regression. After resolving the severe issue, review naming, performance, and style.

What comes first in a layered review of a pagination offset?

Record the input, expected and actual results as a correctness finding. Give a concrete fix and case to protect it before reviewing clarity and the later layers.
