PR Review
See @.agents/skills/pr-review/SKILL.md — that is the canonical skill body. Read it and follow it.
Depth: one pass by default. If the user asked for a deep, deeper, or thorough review, follow the first pass with /code-review high scoped to the PR and fold its confirmed findings into the same report. /code-review ultra <PR#> is user-triggered and billed — mention it, don't launch it.
