`/review` Is Now an Alias for `/code-review`, Which Reuses Your Last Effort Level by Default
Releasebot·medium signal
Claude Code 2.1.223 makes `/review` an alias of `/code-review` for PR reviews, and changes `/code-review` to reuse the last effort level you selected rather than defaulting each time. The two commands had been diverging in behavior since `/code-review` moved to a background subagent in 2.1.218, which made it easy to invoke the wrong one. Effort-level persistence matters cost-wise: an unintended `xhigh` re-run on a large diff is expensive, and an unintended `low` one silently weakens the review.
