repo-architecture-audit

Analyze an existing code repository to identify its key architectural aspects: high-level structure, main components/modules, runtime entrypoints, dependency graph, data flows, deployment shape, and cross-cutting concerns (configuration, auth, logging, errors, testing). Use when a user asks "how is this repo built?", "what are the main pieces?", "where is the entrypoint?", "how do services/modules interact?", or "summarize the architecture." Do NOT use for implementing new features, writing large refactors, or performing destructive actions.
