Cloud Provider Detection Skill

Auto-detect AWS, GCP, or Azure usage with 95%+ accuracy using multi-signal analysis.

Quick Start

const { detectCloudProvider } = require('./detect-cloud-provider.js');

// Auto-detect cloud provider
const result = await detectCloudProvider('/path/to/project');

if (result.detected) {
  console.log(`Detected: ${result.name}`);
  console.log(`Confidence: ${(result.confidence * 100).toFixed(1)}%`);
  console.log(`Signals: ${result.signal_count}`);
}

// Manual override
const awsResult = await detectCloudProvider('/path/to/project', {
  provider: 'aws'
});

Detection Signals

Signal Types (Weighted)

1. Terraform (weight: 0.5) - Highest priority

   • Provider declarations: provider "aws", provider "google", provider "azurerm"
   • Resource types: aws_vpc, google_compute_instance, azurerm_storage_account

2. Package Manifests (weight: 0.3)

   • NPM: @aws-sdk/, @google-cloud/, @azure/
   • Python: boto3, google-cloud-*, azure-*

3. Config Files (weight: 0.3)

   • .aws/config, .gcloud/, .azure/
   • cloudformation.yml, cloudbuild.yaml, azuredeploy.json

4. CLI Scripts (weight: 0.2)

   • aws configure, gcloud compute, az vm
   • Command patterns in .sh files

5. Docker (weight: 0.2)

   • Base images: FROM public.ecr.aws, FROM gcr.io, FROM mcr.microsoft.com

Confidence Scoring

Base Score = Σ(detected_signals × signal_weight) / Σ(all_signal_weights)

Multi-Signal Boost:
  if (signal_count >= 3) {
    confidence += 0.2  // Up to maximum of 1.0
  }

Detection Threshold: ≥0.7 (70%)

CLI Usage

# Detect in current directory
node detect-cloud-provider.js

# Detect in specific project
node detect-cloud-provider.js /path/to/project

# Manual override
node detect-cloud-provider.js /path/to/project --provider aws

# Custom confidence threshold
node detect-cloud-provider.js /path/to/project --min-confidence 0.8

# Exit codes:
#   0 = Provider detected
#   1 = No provider detected
#   2 = Error occurred
