Before returning, apply this skill's verdict, decision, and approval rules to every incomplete item and prepend **Checklist: X/Y complete**<br>**Incomplete: None | section/item — reason; outcome impact; exact next action**; list every incomplete item. ## Tool Routing | Need | Preferred tool | Use it when | Fallback | |---|---|---|---| | Physical and declared architecture | Native file listing, manifests, build files, configuration, and architecture documents | Establishing modules, packages, domains, layers, entrypoints, and deployment units | Targeted repository map from known entrypoints | | Symbols and dependency topology | Language server, compiler metadata, or host-native code intelligence | Tracing imports, calls, implementations, routes, events, and cycles | Narrow sear...
