Example Use Cases

Rails Application Development

Engage Ruby to build a production Rails application.

import { $ } from 'sdk.do'

const task = await $.Agent.invoke({
  agentId: 'ruby',
  task: 'Build SaaS platform backend with Ruby on Rails',
  context: {
    requirements: {
      users: 'multi-tenant SaaS with 1000+ users',
      features: ['authentication', 'api', 'webhooks', 'background jobs', 'payments'],
      scale: 'support 1000 req/sec',
      deployment: 'AWS + Docker',
    },
    timeline: '12 weeks to MVP',
    quality: {
      testing: 'comprehensive test coverage (>90%)',
      codeQuality: 'linting and static analysis',
      documentation: 'API docs and deployment guides',
    },
  },
  deliverables: ['application-code', 'tests', 'api-documentation', 'deployment-config'],
})

API Redesign and Optimization

Have Ruby optimize and redesign existing APIs.

const task = await $.Agent.invoke({
  agentId: 'ruby',
  task: 'Redesign REST API to GraphQL with performance optimization',
  context: {
    currentAPI: {
      type: 'REST',
      endpoints: 50,
      latency: '200-500ms',
      usage: '100K daily requests',
    },
    objectives: ['migrate to GraphQL', 'reduce latency to <100ms', 'implement caching layer', 'add real-time subscriptions'],
    backwardCompatibility: true,
    tools: ['GraphQL Ruby', 'DataLoader', 'Redis'],
  },
  deliverables: ['graphql-schema', 'implementation', 'migration-guide', 'performance-benchmarks'],
})

Rails Performance Optimization

Request Ruby to optimize a Rails application's performance.

const task = await $.Agent.invoke({
  agentId: 'ruby',
  task: 'Optimize Rails application performance and database queries',
  context: {
    currentMetrics: {
      pageLoadTime: '3-5 seconds',
      databaseTime: '60% of response time',
      n1Queries: 'widespread',
      cacheHitRate: '20%',
    },
    objectives: ['reduce page load to <500ms', 'reduce database time to <100ms', 'eliminate N+1 queries', 'achieve 80% cache hit rate'],
    codebase: {
      size: '100K lines',
      testCoverage: '60%',
    },
  },
  deliverables: ['optimization-report', 'code-changes', 'performance-benchmarks', 'best-practices-guide'],
})
