Multi-Agent Orchestration & `google.adk.agents.LoopAgent` +The agent uses an end-to-end multi-agent graph managed by an `OrchestratorLoopAgent` (`google.adk.agents.LoopAgent`): +- **`SourceDiscoveryAgent`** (Phase 0a): Pre-emptively audits and documents the existing pre-migration source environment (As-Is Architecture) and pain points. +- **`DiscoveryAgent`** (Phase 0): Discovers functional & non-functional requirements while explicitly deferring product selection. +- **`ArchitectureDesignAgent`** (Phase 1): Resolves product selections (Cloud Run, Pub/Sub, Cloud Storage, Firestore, IAM, KMS), grounds guidance with **Google Developer Knowledge MCP**, generates Mermaid diagrams (`architecture.mmd`), and builds Terraform IaC (`terraform/main.tf`). +- **`ValidationReviewAgent`** (Phase 2): Evaluates Mermaid syntax, Terraform structural integrity, and artifact completeness using `google.adk.tools.FunctionTool`. +- **`PackagingAgent`** (Phase 3): Compiles the final comprehensive `solution-architecture-guide.md` with **Before (Source) vs After (Target)** architecture comparison. +- **`OrchestratorLoopAgent`**: Repeatedly loops through the multi-agent pipeline, reviewing and validating content in a feedback loop until production quality criteria pass or `max_iterations` is reached. + +### 2.

PostgreSQL Database Persistence (`app/database.py`) +State, sessions, workflow executions, review iteration logs, and evaluation metrics are written to an external PostgreSQL database (with an automatic SQLite fallback for offline development): +- `adk_sessions`: Durable session memory and state data. +- `workflow_executions`: Workflow execution status, phase, and iteration metrics. +- `adk_artifacts`: Generated solution architecture artifacts (including `docs/source-architecture.md` and `source-architecture.mmd`). +- `orchestrator_review_logs`: Detailed iteration review logs from the `OrchestratorLoopAgent`. +- `adk_evaluations`: Benchmark evaluation scores and pass rates. + +### 4.
