description	Migrate existing repositories with provider-specific files (.claude, .cursor, etc.) to OmniDev's unified approach. Consolidates instructions, converts skills/commands to capabilities, and establishes a single source of truth.

OmniDev Migration

This skill guides you through migrating repositories from provider-specific configurations to OmniDev.

When to Use This Skill

• Repository has provider-specific files (.claude/, .cursor/, AGENTS.md, .mcp.json)
• User wants to unify multi-provider configurations
• Team wants a single source of truth for AI agent instructions

Migration Workflow

1. Install OmniDev

npm install -g @omnidev-ai/cli
# or: bun install -g @omnidev-ai/cli

Verify: omnidev --version

2. Initialize in Repository Root

omnidev init

Creates:

• OMNI.md - Project instructions (source of truth)
• omni.toml - Configuration
• .omni/ - Runtime directory (auto-gitignored)

3. Consolidate Instructions

Migrate content FROM (pick what exists):

• CLAUDE.md, AGENTS.md
• .cursor/rules, .cursor/.cursorrules
• .claude/instructions.md

TO OMNI.md:

# Project Name

## Project Description
[2-3 sentences about purpose and functionality]

## Conventions
- Coding standards
- Style preferences
- Testing requirements

## Architecture
- Tech stack
- Key components
- Data flow patterns

DO NOT migrate:

• File tree listings
• Provider-specific tool configs
• Skills/commands (these become capabilities)

4. Convert Skills/Commands to Capabilities

Capability Structure

capabilities/
└── my-project-tools/
    ├── capability.toml      # Metadata
    ├── agents/              # Custom agents (optional)
    ├── commands/            # Commands (optional)
    ├── docs/                # Documentation (optional)
    └── rules/               # Behavior rules (optional)

capability.toml Template

[capability]
id = "my-project-tools"
name = "My Project Tools"
version = "1.0.0"
description = "Project-specific tools and workflows"

[capability.providers]
# Enable for specific providers
claude = true  # alias for claude-code
cursor = true
windsurf = true

Migration Steps

1. Create capability directory:

   mkdir -p capabilities/my-project-tools
   

2. Convert existing skills/commands:

   • .claude/skills/*.ts → capabilities/my-project-tools/commands/
   • Custom agents → capabilities/my-project-tools/agents/
   • Instructions → capabilities/my-project-tools/rules/

3. Register in omni.toml:

   [capabilities.sources]
   my-project-tools = "file://./capabilities/my-project-tools"
   
   [profiles.default]
   capabilities = ["my-project-tools"]
   

5. Migrate MCP Servers

FROM .mcp.json or .cursor/mcp.json:

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path"]
    }
  }
}

TO omni.toml:

[mcp.filesystem]
command = "npx"
args = ["-y", "@modelcontextprotocol/server-filesystem", "/path"]

6. Update .gitignore

Add:

# OmniDev runtime
.omni/
omni.local.toml

# Generated provider files
CLAUDE.md
AGENTS.md
.cursor/rules
.cursor/.cursorrules
.cursor/mcp.json
.mcp.json

Keep in version control: OMNI.md, omni.toml, capabilities/

7. Remove Old Files from Git

# Remove generated files (will be regenerated)
git rm --cached CLAUDE.md AGENTS.md .mcp.json

# Optional: Remove old provider directories after migrating capabilities
# git rm --cached -r .claude/ .cursor/ .opencode/

8. Sync and Verify

omnidev sync    # Generate provider files
omnidev doctor  # Verify configuration

Capability Organization Patterns

Single Capability (Simple Projects)

[capabilities.sources]
project-tools = "file://./capabilities/project-tools"

[profiles.default]
capabilities = ["project-tools"]

Multiple Capabilities (Complex Projects)

[capabilities.sources]
api-tools = "file://./capabilities/api-tools"
deploy-tools = "file://./capabilities/deploy-tools"
test-tools = "file://./capabilities/test-tools"

[profiles.default]
capabilities = ["api-tools", "deploy-tools", "test-tools"]

Profile-Based Organization

[capabilities.sources]
shared = "file://./capabilities/shared"
frontend = "file://./capabilities/frontend"
backend = "file://./capabilities/backend"

[profiles.frontend-dev]
capabilities = ["shared", "frontend"]

[profiles.backend-dev]
capabilities = ["shared", "backend"]

[profiles.fullstack]
capabilities = ["shared", "frontend", "backend"]

Common Migration Scenarios

Cursor with .cursorrules

1. Copy project content to OMNI.md
2. Add .cursor/rules to .gitignore
3. Run omnidev sync

Multiple Providers

1. Consolidate shared instructions into OMNI.md
2. Create provider-specific capabilities if needed
3. Use profiles to manage capability combinations

Team Migration

1. One person completes migration
2. Commit OMNI.md, omni.toml, capabilities/, .gitignore
3. Team runs: npm install -g @omnidev-ai/cli && omnidev sync

Troubleshooting

Provider files not generated: Run omnidev doctor, check active profile has capabilities

MCP servers not working: Verify omni.toml MCP config, check logs with OMNIDEV_DEBUG=1 omnidev sync

Capabilities not loading:

• Verify sources registered in omni.toml
• Check capabilities enabled in active profile
• Ensure file paths correct (use ./ prefix for local)

Verification Checklist

After migration:

• omnidev doctor passes
• omnidev sync generates provider files
• Old provider files in .gitignore
• OMNI.md and omni.toml committed
• Capabilities load correctly
• MCP servers functional (if used)
• Team can reproduce setup
