📚 Clojure + Google ADK + Vertex AI Laboratory

Version: 1.2.0 Last Updated: 2025-10-27 Objective: Complete knowledge base for developing production AI agents using Clojure, Google ADK, and Vertex AI

🎯 Laboratory Vision

This laboratory explores creating AI agent solutions using Clojure as the primary language, integrating:

• Google ADK (Agent Development Kit) via Java SDK (native JVM)
• Python libraries via libpython-clj (NumPy, HuggingFace, etc.)
• Vertex AI Agent Engine for deployment
• Functional programming for agent orchestration

🏗️ Technology Stack

📖 Key Concepts

Agent Types (A/B/C/D Taxonomy)

This lab uses a validated taxonomy of agent types based on capabilities:

• Type A: Pure AI (input → LLM → output) - ~$0.02, ~3s
• Type B: AI + CAG (Context-Aware Generation with database) - ~$0.08, ~5s
• Type C: AI + Web (Grounding with external APIs) - ~$0.18, ~12s
• Type D: AI + CAG + Web (maximum context) - ~$0.42, ~17s

Multi-Model Strategy

Optimize costs by routing tasks to appropriate models:

• Gemini Flash (70%): Simple tasks, extraction, classification
• Claude Haiku (20%): Medium complexity, personalization
• Claude Sonnet (10%): Complex reasoning, consolidation

Result: 41% cost reduction vs Claude-only approach

🏥 Healthcare Pipeline (Production-Ready)

Complete 5-system pipeline for regulated medical content generation:

1. S.1.1 (Type B): LGPD-compliant data extraction
2. S.1.2 (Type A): Medical claims identification
3. S.2-1.2 (Type C): Scientific reference search (PubMed, Scholar)
4. S.3-2 (Type B): SEO optimization with professional profile
5. S.4 (Type D): Final consolidation with compliance

Validated ROI

Real case: Clínica Mente Saudável (20 posts/month)

• ⏱️ Time: 4h 15min → 1.5min (-99.4%)
• 💰 Cost: R$ 192.50 → R$ 14.70 (-92.4%)
• 📈 ROI: -R$ 3,850 → +R$ 3,094 (+180%)

💡 Key Insights

★ Functional Programming + AI Agents: Clojure's immutability and REPL-driven development are excellent for agent orchestration and testing.

★ JVM Native Advantage: Using Google ADK Java SDK directly (no Python wrapper) provides better performance and type safety.

★ Cost Optimization Matters: Multi-model strategy (Gemini Flash 70%, Claude 20%, Sonnet 10%) reduces costs by 41% vs single-model approach.

★ Type System for Agents: The A/B/C/D taxonomy based on capabilities (not implementation) enables systematic architecture decisions and cost optimization.

★ Healthcare ROI Validated: -99.4% time and -92.4% cost reduction proven in production with Clínica Mente Saudável case study.
