Installation

Option 1: Plugin Installation (Recommended) 🎯

Status: Coming soon - awaiting Claude Code marketplace

When the Claude Code marketplace becomes available, you'll be able to install with a single command:

/plugin install devsolo

This automatically:

• Installs the MCP server
• Registers all 13 slash commands
• Configures the sub-agents (git-droid, docs-droid)
• No manual configuration required!

For testing or development, see Plugin Installation Guide.

Option 2: Manual MCP Setup (Alternative)

If you prefer manual control or are testing local changes:

1. Clone and build the devsolo repository:

   git clone https://github.com/slamb2k/devsolo.git
   cd devsolo
   npm install
   npm run build

2. Configure Claude Code to load the MCP server: Add to your Claude Code MCP configuration file:

   {
     "mcpServers": {
       "devsolo": {
         "command": "node",
         "args": ["/path/to/devsolo/dist/mcp/devsolo-mcp-server.js"]
       }
     }
   }

3. Restart Claude Code to load the MCP tools

4. Initialize in your project using natural language:

   "Initialize devsolo in this project"

   Claude will invoke the devsolo_init tool automatically.

For detailed installation instructions, see the Installation Guide.

Quick Start

New to devsolo? Follow these steps to get started with Claude Code.

Two Ways to Use devsolo

devsolo provides both native slash commands and direct MCP tool calls for maximum flexibility:

Option 1: Slash Commands (Recommended) 🎯

/devsolo:init       - Initialize devsolo
/devsolo:launch     - Start a new feature
/devsolo:commit     - Commit changes
/devsolo:ship       - Ship your changes (full workflow)
/devsolo:status     - Check current status

Option 2: Natural Language (Direct MCP Tool Calls)

"Use devsolo_init to initialize devsolo in this project"
"Use devsolo_launch to start a new feature for authentication"
"Use devsolo_ship to commit, push, create PR, and merge"

Slash commands provide better integration, auto-completion, and coordinated workflows via specialized sub-agents (git-droid, docs-droid)!

1. Initialize devsolo in your project

Using slash command:

/devsolo:init

Or using natural language:

Use devsolo_init to initialize devsolo in this project

This creates a .devsolo directory with configuration and session storage.

2. (Optional) Set up GitHub authentication

# Option A: GitHub CLI (easiest)
gh auth login

# Option B: Personal access token
export GITHUB_TOKEN=ghp_your_token_here

3. Start a new feature workflow

Using slash command:

/devsolo:launch

Or using natural language:

Use devsolo_launch to start a new feature for [your feature description]

This creates a new feature branch and starts tracking your workflow.

4. Make your changes

Work on your feature as normal. devsolo tracks your session automatically.

Check status:

/devsolo:status

5. Ship your changes (One Command! 🚀)

Using slash command:

/devsolo:ship

Or using natural language:

Use devsolo_ship to commit, push, create PR, and merge this feature

That's it! This single MCP tool call:

• ✅ Commits your changes
• ✅ Pushes to remote
• ✅ Creates or updates PR
• ✅ Waits for CI checks
• ✅ Auto-merges when ready
• ✅ Syncs main branch
• ✅ Deletes feature branches
• ✅ Completes session

Ready for your next feature! 🎉

Enable Status Line (Optional)

For always-visible workflow status in Claude Code:

/devsolo:status-line

Slash Commands

devsolo provides native Claude Code slash commands for all functionality. Type /devsolo in Claude Code to see the full list.

Available Commands

| Command | Description | Example | |--------|-------------|---------| | /devsolo:init | Initialize devsolo in your project | /devsolo:init | | /devsolo:launch | Start a new feature workflow | /devsolo:launch | | /devsolo:commit | Commit changes with a message | /devsolo:commit | | /devsolo:ship | Complete workflow (commit, push, PR, merge) | /devsolo:ship | | /devsolo:swap | Switch between workflow sessions | /devsolo:swap feature/other-branch | | /devsolo:abort | Abort current workflow session | /devsolo:abort | | /devsolo:sessions | List all workflow sessions | /devsolo:sessions | | /devsolo:status | Show current workflow status | /devsolo:status | | /devsolo:cleanup | Clean up expired sessions | /devsolo:cleanup | | /devsolo:hotfix | Create emergency hotfix workflow | /devsolo:hotfix | | /devsolo:status-line | Manage Claude Code status line | /devsolo:status-line | | /devsolo:prime | Prime understanding of codebase | /devsolo:prime | | /devsolo:docs | Manage documentation | /devsolo:docs |

How Slash Commands Work

When you use a slash command like /devsolo:launch, Claude Code:

1. Displays the unique ASCII art banner for immediate visual feedback
2. Orchestrates the workflow using specialized sub-agents (git-droid, docs-droid)
3. Invokes the appropriate MCP tools for execution
4. Returns structured results with pre/post-flight checks

Benefits of slash commands:

• 🎯 Discoverable - Shows up in / menu with auto-completion
• ⚡ Fast - Quick access to commands with visual feedback
• 📝 Guided - Parameter hints and descriptions built-in
• 🤖 Smart - Coordinated by specialized sub-agents for intelligent workflows
• 🔄 Flexible - Can still use natural language for direct MCP tool calls

Architecture

devsolo uses a plugin architecture with clear separation of concerns:

User → Slash Command → Sub-Agent → MCP Tools → Git/GitHub
         ↓              ↓            ↓
    Orchestration   Coordination   Execution

Sub-Agents

devsolo includes specialized sub-agents for intelligent coordination:

• git-droid 🤖 - Git workflow coordination and automation

  • Manages branch creation and cleanup
  • Coordinates multi-step git operations
  • Provides intelligent defaults for git workflows
  • Handles state transitions and safety checks

• docs-droid 📚 - Documentation management and validation

  • Enforces documentation structure and naming conventions
  • Automatically places docs in correct locations
  • Maintains README.md indexes
  • Archives outdated documentation

How It Works

1. Slash commands provide the user interface and high-level orchestration
2. Sub-agents coordinate operations with git-aware intelligence
3. MCP tools execute focused, single-purpose operations
4. Services provide core functionality (git operations, GitHub API, etc.)

This architecture ensures maintainability, testability, and a great user experience.

  severity: 'error' | 'warning' | 'info';
  details?: {
    expected?: any;
    actual?: any;
    suggestion?: string;
  };
}

See docs/guides/validation.md for complete documentation.

Workflow States

devsolo uses a deterministic state machine to manage workflows:

INIT → BRANCH_READY → CHANGES_COMMITTED → PUSHED →
PR_CREATED → WAITING_APPROVAL → MERGED → COMPLETE

Each state has specific allowed transitions and validations to ensure workflow integrity.

GitHub Integration

devsolo integrates with GitHub API for automated PR management.

Setup

Option 1: Use GitHub CLI (Recommended for local development)

gh auth login

Option 2: Set environment variable (For CI/CD)

export GITHUB_TOKEN=your_github_token
# or
export GH_TOKEN=your_github_token

devsolo automatically detects and uses gh CLI authentication if available.

Features

• Automatic PR creation with generated descriptions
• CI check monitoring with configurable timeout
• Review status tracking
• Squash merge support
• Automatic branch cleanup

Status Line Integration

The status line provides at-a-glance workflow information directly in Claude Code:

[devsolo] 💻 0c2a20a7 | feature/my-feature | BRANCH_READY

Status Line Components:

• Session ID: Short identifier for current session
• Branch Name: Current feature branch
• State: Workflow state (BRANCH_READY, PUSHED, etc.)

Managing the Status Line:

Use devsolo_status_line with action "enable"
Use devsolo_status_line with action "disable"
Use devsolo_status_line with action "show"
Use devsolo_status_line with action "update" and showBranchInfo true

Session Management

Sessions are stored in .devsolo/sessions/ with automatic persistence:

• Each workflow creates a unique session ID
• Sessions track state history and transitions
• Automatic lock management prevents conflicts
• Sessions expire after 30 days of inactivity

Configuration

Configuration is stored in .devsolo/config.yaml:

initialized: true
scope: project
gitPlatform:
  type: github
  owner: your-org
  repo: your-repo
preferences:
  defaultBranchPrefix: feature/
  autoCleanup: true
  prTemplate:
    footer: "🤖 Generated with devsolo"
