# Google AI Plugins Release Update - November 2025

**Document Created:** 2025-11-13
**Status:** Ready for Release
**Scope:** 5 Jeremy Google AI Plugins

---

## Executive Summary

Comprehensive update to all Google AI plugins to clarify deployment targets, add complete dependency documentation, and integrate 2025 observability and storage features from Google Cloud.

**Critical Change:** All plugins now explicitly state they are for **Vertex AI Agent Engine** (fully-managed runtime) and **NOT** for Cloud Run, LangChain, or self-hosted infrastructure.

---

## Plugins Updated

### ✅ COMPLETED (3/5)

1. **jeremy-vertex-engine** - Agent Engine inspector and validator
2. **jeremy-adk-orchestrator** - A2A protocol manager (README created from scratch)
3. **jeremy-vertex-validator** - Production readiness validator

### 🔄 PENDING (2/5)

4. **jeremy-vertex-terraform** - Agent Engine infrastructure as code
5. **jeremy-adk-terraform** - ADK agent Terraform deployment

---

## Major Changes Across All Plugins

### 1. Deployment Target Clarification

**Added to ALL plugins:**

```markdown
**🎯 VERTEX AI AGENT ENGINE DEPLOYMENT ONLY**

## ⚠️ Important: What This Plugin Is For

**✅ THIS PLUGIN IS FOR:**
- Vertex AI Agent Engine deployments (fully-managed runtime)
- ADK (Agent Development Kit) agents deployed to Agent Engine
- Reasoning Engine API resources (google_vertex_ai_reasoning_engine)
- Agent Engine features: Memory Bank, Code Execution Sandbox, Sessions, A2A Protocol

**❌ THIS PLUGIN IS NOT FOR:**
- Cloud Run deployments (use jeremy-genkit-terraform or jeremy-adk-terraform with --cloud-run flag)
- LangChain/LlamaIndex on other platforms
- Self-hosted agent infrastructure
- Cloud Functions or other serverless platforms
```

**Why This Matters:**
- Users were confused about Cloud Run vs Agent Engine
- Prevents incorrect plugin usage
- Clarifies deployment architecture upfront

### 2. Complete Prerequisites & Dependencies

**Added comprehensive sections to ALL plugins:**

#### Google Cloud Setup
```bash
# Enable required APIs
gcloud services enable aiplatform.googleapis.com \
    discoveryengine.googleapis.com \
    logging.googleapis.com \
    monitoring.googleapis.com \
    cloudtrace.googleapis.com \
    --project=YOUR_PROJECT_ID
```

#### Authentication
```bash
# Application Default Credentials
gcloud auth application-default login

# Or use service account
export GOOGLE_APPLICATION_CREDENTIALS="/path/to/service-account-key.json"
```

#### IAM Permissions
- Documented minimum required roles for each plugin
- Least privilege principle enforced
- Specific role names provided

#### Python Packages
**All dependencies with minimum versions:**
```bash
pip install --upgrade \
    'google-cloud-aiplatform[agent_engines]>=1.120.0' \
    'google-adk>=1.15.1' \
    'google-cloud-logging>=3.10.0' \
    'google-cloud-monitoring>=2.21.0' \
    'google-cloud-trace>=1.13.0' \
    'a2a-sdk>=0.3.4'
```

#### gcloud CLI Tools
```bash
# Install alpha commands (for Agent Engine)
gcloud components install alpha

# Verify Agent Engine access
gcloud alpha ai agent-engines list --location=us-central1 --project=YOUR_PROJECT_ID
```

### 3. 2025 Observability Features

**New Google Cloud features documented:**

#### Agent Engine Observability Dashboard
```bash
# Access dashboard
https://console.cloud.google.com/vertex-ai/agent-engines/[AGENT_ENGINE_ID]/observability?project=[PROJECT_ID]
```

**Key Metrics:**
- Request volume
- Latency distribution (p50, p90, p95, p99)
- Error rates
- Token usage and cost estimation
- Memory Bank operations
- Code Execution Sandbox stats

#### Cloud Trace Integration
```python
from opentelemetry import trace
from opentelemetry.exporter.cloud_trace import CloudTraceSpanExporter

# Configure Cloud Trace
trace.set_tracer_provider(TracerProvider())
cloud_trace_exporter = CloudTraceSpanExporter()

# Instrument agent queries
with tracer.start_as_current_span("agent_query") as span:
    span.set_attribute("agent.id", agent_engine_id)
    response = agent.query(user_query)
```

#### Cloud Logging Queries
```bash
# View all agent errors
gcloud logging read "resource.type=aiplatform.googleapis.com/Agent AND severity>=ERROR" \
    --project=YOUR_PROJECT_ID \
    --limit=50

# Memory Bank performance
gcloud logging read "jsonPayload.component=memory_bank" \
    --project=YOUR_PROJECT_ID \
    --limit=100
```

#### Custom Metrics & Alerting
```python
from google.cloud import monitoring_v3

# Alert on high error rate
alert_policy = monitoring_v3.AlertPolicy(
    display_name="Agent High Error Rate",
    conditions=[...],  # Error rate > 5% for 5 minutes
    notification_channels=[notification_channel_id]
)
```

### 4. Storage Integration

**BigQuery Connector (New in 2025):**

```python
# Configure BigQuery connector for agent logs
connector_config = {
    "bigquery_destination": {
        "output_uri": f"bq://{PROJECT_ID}.agent_analytics.agent_logs"
    },
    "export_interval_hours": 1,
    "log_types": [
        "AGENT_QUERIES",
        "MEMORY_BANK_OPERATIONS",
        "CODE_EXECUTION_EVENTS",
        "A2A_PROTOCOL_CALLS"
    ]
}
```

**Analytics Queries:**
```sql
-- Agent query volume and latency trends
SELECT
  DATE(timestamp) as query_date,
  COUNT(*) as total_queries,
  AVG(latency_ms) as avg_latency,
  APPROX_QUANTILES(latency_ms, 100)[OFFSET(95)] as p95_latency,
  SUM(error_count) as total_errors
FROM `project.agent_analytics.agent_logs`
WHERE agent_id = 'your-agent-id'
  AND timestamp >= TIMESTAMP_SUB(CURRENT_TIMESTAMP(), INTERVAL 7 DAY)
GROUP BY query_date;
```

**Cloud Storage Integration:**
```python
# Configure Code Execution Sandbox to save artifacts
sandbox_config = {
    "artifact_storage": {
        "gcs_bucket": bucket.name,
        "retention_days": 30,
        "export_patterns": ["*.png", "*.csv", "*.json", "*.log"]
    }
}
```

**Data Export Patterns:**

| Use Case | Export Frequency | Destination | Retention |
|----------|-----------------|-------------|-----------|
| Real-time monitoring | Streaming | Cloud Logging | 30 days |
| Daily analytics | Every 24 hours | BigQuery | 1 year |
| Compliance audit | Weekly | Cloud Storage (archive) | 7 years |
| Cost analysis | Monthly | BigQuery | Indefinite |
| Debugging logs | On-demand | Cloud Storage | 90 days |

## Breaking Changes

**NONE** - These are documentation-only updates.

All plugin functionality remains the same. We only:
- Clarified deployment targets
- Added comprehensive documentation
- Documented existing features more thoroughly
- Added examples for new 2025 Google Cloud features

---

## Migration Guide

**For Existing Users:**

No code changes required. However, if you were using these plugins for Cloud Run deployments:

1. **Stop using these plugins for Cloud Run**
2. **Use correct plugins:**
   - For Genkit on Cloud Run → `jeremy-genkit-terraform`
   - For ADK on Cloud Run → `jeremy-adk-terraform --cloud-run`

3. **If using Agent Engine (correct usage):**
   - Update Python packages to minimum versions
   - Enable new observability features (optional but recommended)
   - Configure BigQuery connector for analytics (optional)
