Woofun AI reports that Anthropic has restructured the pricing and functionality of Claude Code's /code-review feature into five distinct tiers: Low, Medium, High, X-high, and Ultra. Each tier employs a unique review process rather than relying on uniform prompts. The Low tier performs a quick scan, while Medium offers multi-perspective analysis. High introduces an independent sub-Agent for validation, and X-high assesses the impact of changes on surrounding code. Official self-tests indicate the Low tier identifies 17% of bugs, compared to 8% for an unnamed competitor, with X-high raising detection to 25% at a cost of approximately $2 per review. The Ultra tier deploys a set of review Agents in the cloud to independently reproduce and validate issues, a process lasting 5 to 10 minutes. Pro and Max users receive three complimentary one-time review credits, after which fees range from $5 to $20 per review.
