Pipeline Overview
This is an 8-agent pipeline for retail site selection analysis:
User Query
↓
IntakeAgent ────────────→ Extract location + business type
↓
MarketResearchAgent ────→ Google Search for demographics
↓
CompetitorMappingAgent ─→ Google Maps Places API
↓
GapAnalysisAgent ───────→ Python code execution (pandas)
↓
StrategyAdvisorAgent ───→ Extended thinking synthesis
↓
ParallelAgent ──────────→ Concurrent artifact generation
├── ReportGenerator ─→ HTML report
├── InfographicAgent → Image generation
└── AudioOverview ───→ TTS podcast audio
What Each Agent Does
| Agent | Purpose | Key Tool/Feature |
|---|---|---|
| IntakeAgent | Parse user request | AgentTool pattern |
| MarketResearchAgent | Find market data | google_search built-in |
| CompetitorMappingAgent | Map competitors | Google Maps API |
| GapAnalysisAgent | Calculate viability | Code execution (pandas) |
| StrategyAdvisorAgent | Synthesize recommendations | Extended thinking |
| ReportGenerator | Create HTML report | Artifact generation |
| InfographicAgent | Generate visual | Image generation |
| AudioOverview | Create podcast audio | TTS multi-speaker |
Key ADK Concepts
Agents
- LlmAgent: Single LLM call with tools and instructions
- SequentialAgent: Runs sub-agents one after another
- ParallelAgent: Runs sub-agents concurrently
State Flow
Data passes between agents via session state:
IntakeAgent → state["target_location"], state["business_type"]
MarketResearchAgent → state["market_research_findings"]
CompetitorMappingAgent → state["competitor_analysis"]
GapAnalysisAgent → state["gap_analysis"]
StrategyAdvisorAgent → state["strategic_report"]
Tools
Functions that agents can call to perform actions. Access state via ToolContext.
Callbacks
Lifecycle hooks: before_agent_callback and after_agent_callback.
