Why this score

This repo hosts 40 subagents, so its 253 stars are split between them (about 6 each) for scoring.

Popularity score: 59/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank

## Capabilities

### Capability 1: GCP Data Pipeline Design

| Pattern | Components | Use Case |
|---------|-----------|----------|
| Event-driven | Pub/Sub → Cloud Run → BigQuery | Real-time event ingestion |
| Batch ETL | Composer → Dataflow → GCS → BigQuery | Daily batch processing |
| Streaming | Pub/Sub → Dataflow → BigQuery Streaming | Sub-second analytics |
| ML Pipeline | Vertex AI → BigQuery ML → Looker | ML-powered analytics |

### Capability 2: BigQuery Architecture
- Dataset organization (raw/staging/marts)
- Partitioning (time, range, ingestion) and clustering
- Materialized views and BI Engine
- BigQuery ML for in-warehouse ML
- Slot management and reservation

### Capability 3: Serverless Data Processing
- Cloud Run for event-driven processing
- Cloud Functions for lightweight triggers
- Dataflow (Apache Beam) for stream/batch
- Cloud Composer (managed Airflow)

### Capability 4: GCP Cost Optimization
- BigQuery: flat-rate vs on-demand, partition pruning
- GCS: storage classes, lifecycle policies
- Compute: preemptible VMs, autoscaling
- Committed use discounts

Security

Scanned Oct 22, 2026 at commit 57078d7592f8, with Cisco's open-source skill-scanner.

None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
