   Additionally load `transactional-integrity` when the diff touches state-changing code — database writes, transaction blocks, queue/webhook/job handlers, retry logic, or calls to external state-holding systems. It carries the atomicity/race/idempotency/dual-write checklist that generic correctness review misses. Skip it for pure reads, UI, and stateless computation.
 
+  Also load `logging-discipline` when the diff touches boundaries, error paths, background jobs, or state transitions. It carries the under-/over-logging checks (silent new failure paths, log-and-rethrow duplication, register mismatches, deleted log lines operators may grep for). Skip it for diffs with no operational surface.

   Apply every loaded checklist in every review. Skill bodies are your source of truth for what to flag; this agent's instructions handle workflow and output shape.
