  "summary": "Static review of proposed JVM GC/performance changes for evidence — collector selection (G1/ZGC/Generational ZGC/Shenandoah/Parallel), allocation pressure, heap-sizing flags, and OOM/leak triage from user-supplied GC logs, JFR, and heap-dump analysis output. Refuses GC-switch recommendations without pause-time evidence. Reads source and sanitized configuration only.",

  "security_notes": "Static review only — reads Java/Kotlin source, JVM startup-flag configuration (launch scripts, Dockerfiles, systemd units, K8s manifests), and user-supplied GC logs, JFR recordings, and heap-dump analysis output (dominator-tree/leak-suspects text, not a raw .hprof binary). Never opens a live process, attaches a profiler or debugger, invokes a JDK tool against a running JVM, or requests/opens a live heap dump. Never requests credentials, connection strings, tenant identifiers, or customer data — ask for sanitized excerpts with placeholders.",
