Performs a high-signal senior-engineer PR review of code changes, classifies how critical the changed surfaces are, and decides whether the PR can be self-merged or must go to a human reviewer. Use this skill for pull request reviews, branch diffs, pasted diffs, uncommitted changes, GitHub PR URLs, or requests like "review my changes", "check this PR", "is this ready", "can I merge this", "does this need a reviewer", "how risky is this change", "what could this break", "audit this diff", "sanity check before I push", or "does this look clean". Covers correctness, security, contracts, blast radius, prior failed fixes in the same code path, tests, maintainability, and regressions while aggressively avoiding noisy false positives. When the PR title contains [CU- ], reads the ClickUp ticket and verifies the diff builds the feature the ticket describes. Designed to work reliably even with smaller/cheaper models.
