Droid & Amp Adapter Implementation Plan

Based on research findings from Task #38, this document outlines implementation plans for the two high-value missing adapters.

Droid Adapter (Factory AI)

Overview

• **Tool**: Factory Droid CLI by Factory AI
• **Type**: Enterprise AI coding agent with terminal integration
• **Performance**: Top performer on terminal benchmarks (58.75% score)
• **Key Features**: End-to-end development workflows, debugging, refactoring, CI/CD integration

Implementation Plan

Phase 1: Research & Setup

• [ ] Install droid CLI: npm install -g @factory/droid-cli
• [ ] Research authentication methods (API keys, OAuth)
• [ ] Analyze CLI command structure and output formats
• [ ] Document session file locations and formats

Phase 2: Basic Adapter

export class DroidAdapter extends BaseAgentAdapter {
  readonly agent = 'droid' as const;
  readonly displayName = 'Factory Droid';
  readonly cliCommand = 'droid';
  readonly minVersion = '1.0.0';
  
  readonly capabilities: AgentCapabilities = {
    agent: 'droid',
    canResume: true,
    canFork: true,
    supportsMultiTurn: true,
    sessionPersistence: 'file',
    supportsTextStreaming: true,
    supportsToolCallStreaming: true,
    supportsNativeTools: true,
    // ... additional capabilities
  };
}

Phase 3: Advanced Features

• [ ] Session management integration
• [ ] MCP plugin support via droid's extension system
• [ ] Cost tracking for enterprise billing
• [ ] Headless mode support for automation

Phase 4: Testing & Documentation

• [ ] Unit tests covering all capabilities
• [ ] Integration tests with mock scenarios
• [ ] Documentation page: docs/02-agents/droid.md
• [ ] Docker E2E integration

Amp Adapter (Sourcegraph)

Overview

• **Tool**: Amp CLI by Sourcegraph
• **Type**: Agentic coding assistant with multi-model support
• **Key Features**: Multi-model routing, specialized subagents, Oracle model, VS Code integration

Implementation Plan

Phase 1: Research & Setup

• [ ] Install amp CLI: npm install -g @sourcegraph/amp-cli
• [ ] Research authentication (Sourcegraph tokens)
• [ ] Analyze command structure: amp chat, amp exec, etc.
• [ ] Study output formats and event streaming

Phase 2: Basic Adapter

export class AmpAdapter extends BaseAgentAdapter {
  readonly agent = 'amp' as const;
  readonly displayName = 'Sourcegraph Amp';
  readonly cliCommand = 'amp';
  readonly minVersion = '2.0.0';
  
  readonly capabilities: AgentCapabilities = {
    agent: 'amp',
    canResume: true,
    canFork: true,
    supportsMultiTurn: true,
    sessionPersistence: 'file',
    supportsTextStreaming: true,
    supportsToolCallStreaming: true,
    supportsNativeTools: true,
    supportsSubagentDispatch: true, // Amp's specialized subagents
    // ... additional capabilities
  };
}

Phase 3: Advanced Features

• [ ] Multi-model selection support
• [ ] Subagent integration (Oracle, Librarian)
• [ ] VS Code extension coordination
• [ ] Remote code reading capabilities

Phase 4: Testing & Documentation

• [ ] Comprehensive test suite
• [ ] Mock harness scenarios
• [ ] Documentation: docs/02-agents/amp.md
• [ ] Docker E2E integration

Implementation Priority

Phase 1: Droid (Recommended First)

**Rationale:**

• More mature enterprise tool
• Clear CLI interface
• Strong performance benchmarks
• Better documented API

Phase 2: Amp

**Rationale:**

• Complex multi-model architecture
• Tight VS Code integration may complicate CLI usage
• Newer tool with potentially evolving interface

Resource Requirements

Development Time

• **Droid**: ~2-3 weeks (basic implementation)
• **Amp**: ~3-4 weeks (due to complexity)

Testing Infrastructure

• Update Docker E2E matrix with new adapters
• Add mock scenarios for both tools
• Integration with existing test suites

Documentation

• Per-adapter documentation pages
• Tutorial examples
• Installation guides
• Troubleshooting sections

Success Criteria

Droid Adapter Complete When:

• [ ] Basic chat functionality working
• [ ] Session resume/fork operational
• [ ] Cost tracking implemented
• [ ] All tests passing (>20 test cases)
• [ ] Documentation complete
• [ ] Docker E2E integration

Amp Adapter Complete When:

• [ ] Multi-model selection working
• [ ] Subagent dispatch functional
• [ ] Stream processing reliable
• [ ] All tests passing (>25 test cases)
• [ ] Documentation complete
• [ ] Docker E2E integration

This implementation plan addresses the findings from Task #38 and provides a roadmap for adding the two most valuable missing adapters to adapters.
