DevHub Skill

DevHub is a multi-project development environment manager that lets you start, stop, and monitor all your local development services from one place.

When to Use This Skill

Use DevHub when the user wants to:

  • Set up a new project for local development
  • Generate a devhub.toml configuration file
  • Start, stop, or restart development services
  • Check the status of running services
  • Manage multiple projects or services
  • View logs from services
  • Manage favorite projects

Primary Workflow: Setting Up a New Project

Step 1: Preview Discovery (Always Do This First)

devhub discover --dry-run

This shows what DevHub would detect without writing any files. Review the output with the user before proceeding.

Step 2: Generate Configuration

If the preview looks correct:

devhub discover

This creates devhub.toml in the project root.

Step 3: Register the Project

devhub register

This adds the project to DevHub's registry so it can be managed globally.

Step 4: Start Services

devhub start

Or start a specific service:

devhub start -s api

Key Commands Quick Reference

| Command | Purpose | |---------|---------| | devhub discover --dry-run | Preview auto-detection | | devhub discover | Generate devhub.toml | | devhub register | Add project to registry | | devhub start [project] | Start all services | | devhub stop [project] | Stop all services | | devhub status | Show all project statuses | | devhub logs <project> -f | Follow service logs | | devhub list | List all registered projects |

Supported Project Types

DevHub auto-detects these project types:

| Type | Detection File | Default Command | |------|---------------|-----------------| | Rust | Cargo.toml | cargo run | | Node.js | package.json | npm run dev | | Python (UV) | pyproject.toml | uv run python | | Python (pip) | requirements.txt | python | | Go | go.mod | go run . | | Flutter | pubspec.yaml | flutter run | | Docker | docker-compose.yml | docker compose up |

Monorepo Support

When no root project marker is found, DevHub scans subdirectories and creates a multi-service configuration automatically.

Best Practices

  1. Always preview first: Run devhub discover --dry-run before generating config
  2. Review generated config: Check the devhub.toml and adjust ports/commands if needed
  3. Use favorites: Mark frequently-used projects with devhub fav add <project>
  4. Check for conflicts: Run devhub ports --check to detect port conflicts
  5. Follow logs: Use devhub logs <project> -f to monitor service output
