João Salavisa 85ecf7debb feat(agentctl): protocol adapter abstraction with agent profile support (#15)
* feat(agentctl): implement protocol adapter abstraction

- Add AgentAdapter interface for protocol-agnostic agent communication
- Create ACPAdapter implementation for ACP protocol (JSON-RPC over stdin/stdout)
- Add Protocol field to agent registry (AgentTypeConfig)
- Update process.Manager to use adapters instead of hardcoded ACP
- Update API layer to use adapter interface
- Pass protocol from registry to agentctl via CLI flag and env var
- Support protocol configuration in both Docker and standalone modes

This refactoring allows agentctl to support multiple protocols (ACP, REST, MCP)
via a pluggable adapter pattern. The backend remains protocol-agnostic,
always communicating with agentctl's HTTP API.

* refactor(agentctl): consolidate types and clean up code

- Create shared types package (internal/agentctl/types) for permission types
- Create shared protocol package (pkg/agent) for Protocol type
- Remove duplicate permission types from acp/client.go and adapter.go
- Make adapter the single source of truth for session ID
- Remove unused Command field from adapter.Config
- Remove passthrough wrapper function handleAdapterPermissionRequest
- Clean up extra empty lines in process/manager.go and acp_adapter.go
- Re-export permission types from adapter package for convenience

* fix(agent-session): rename AgentType to AgentProfileID for consistency

- Rename AgentSession.AgentType to AgentProfileID in models
- Update agent_sessions table schema column from agent_type to agent_profile_id
- Update all SQL queries in sqlite.go to use agent_profile_id
- Fix ToAPI() method to return agent_profile_id key
- Remove misleading comments in executor.go

Also adds comprehensive tests for affected areas:
- adapter package unit tests (SessionUpdate, PlanEntry, AgentInfo, Config)
- profile resolver unit tests with mock repository
- AgentSession CRUD tests in sqlite_test.go

Kandev - Kanban Board with AI Agent Orchestration

A Kanban board system that integrates AI agent orchestration capabilities with real-time Agent Communication Protocol (ACP) streaming, allowing tasks to be automatically executed by AI agents running in isolated Docker containers.

Overview

Kandev combines traditional Kanban task management with automated AI agent execution and real-time feedback streaming. Users create tasks on a Kanban board, and when configured with an AI agent type, the system automatically launches Docker containers to execute those tasks against specified code repositories. Real-time progress, logs, and results are streamed from agents to the frontend via WebSocket connections.

Key Features

  • Kanban Board Management: Create and manage tasks across multiple boards with columns
  • AI Agent Orchestration: Launch AI agents (Augment Agent) to execute tasks
  • Real-Time ACP Streaming: Live progress updates, logs, and results streamed from agents
  • Session Resumption: Agents can resume previous conversations using session IDs
  • Docker Isolation: Each agent runs in an isolated Docker container with resource limits
  • Repository Integration: Agents can work on code repositories with host credentials
  • Host Credential Mounting: Secure read-only mounting of SSH keys and Git credentials
  • SQLite Persistence: Lightweight file-based database for task and board storage
  • Local Deployment: Designed for client machines with minimal dependencies

Architecture

The system runs as a unified Go binary that includes:

  • Task Service: Manages tasks, boards, and columns with SQLite persistence
  • Agent Manager: Manages Docker container lifecycle and ACP message streaming
  • Orchestrator: Coordinates agent launches and monitors execution
  • WebSocket API: Real-time bidirectional communication for all operations (Port 8080)

Agent Communication Protocol (ACP)

ACP is a JSON-based streaming protocol that enables real-time communication between AI agents and the backend:

Agent Container (stdout) → Agent Manager → Event Bus → API

Message Types: progress, log, result, error, status, heartbeat

See docs/ARCHITECTURE.md for detailed architecture documentation.

Supported Agent Types

  1. Augment Agent (augment-agent)
    • Uses Auggie CLI for code analysis, generation, debugging, refactoring
    • Native ACP support via stdout JSON streaming
    • Session resumption for multi-turn conversations

Technology Stack

  • Backend: Go 1.21+
  • Database: SQLite (with WAL mode)
  • Container Runtime: Docker
  • Web Framework: Gin
  • Logging: Zap (structured logging)
  • Deployment: Single binary for client machines

Quick Start

Prerequisites

  • Go 1.21 or higher
  • Docker
  • Augment CLI credentials (~/.augment/session.json)

Build and Run

cd apps/backend

# Build the binary
make build

# Run the server (creates kandev.db in current directory)
./bin/kandev

# Or specify a custom database path
KANDEV_DB_PATH=/path/to/kandev.db ./bin/kandev

WebSocket API Usage

Connection: ws://localhost:8080/ws

Message Envelope

{
  "id": "correlation-uuid",
  "type": "request|response|notification|error",
  "action": "action.name",
  "payload": {},
  "timestamp": "2026-01-10T10:30:00Z"
}

Key Message Actions

  • board.create - Create board
  • board.list - List boards
  • column.create - Create column
  • task.create - Create task
  • agent.launch - Launch agent
  • agent.status - Get agent status
  • orchestrator.start - Start task execution

Example Usage (JavaScript)

const ws = new WebSocket('ws://localhost:8080/ws');

// Create a board
ws.send(JSON.stringify({
  id: crypto.randomUUID(),
  type: 'request',
  action: 'board.create',
  payload: { name: 'My Project', description: 'Project tasks' }
}));

// Create a task
ws.send(JSON.stringify({
  id: crypto.randomUUID(),
  type: 'request',
  action: 'task.create',
  payload: {
    board_id: '{board_id}',
    column_id: '{column_id}',
    title: 'Fix login bug',
    description: 'Users cannot login'
  }
}));

// Launch an agent
ws.send(JSON.stringify({
  id: crypto.randomUUID(),
  type: 'request',
  action: 'agent.launch',
  payload: {
    task_id: '{task_id}',
    agent_type: 'augment-agent',
    workspace_path: '/path/to/project',
    env: {
      AUGMENT_SESSION_AUTH: '...',
      TASK_DESCRIPTION: 'What is 2+2?'
    }
  }
}));

// Handle responses and notifications
ws.onmessage = (event) => {
  const msg = JSON.parse(event.data);
  if (msg.type === 'response') {
    console.log('Response:', msg.payload);
  } else if (msg.type === 'notification') {
    // Real-time updates: acp.progress, acp.log, task.updated, etc.
    console.log('Notification:', msg.action, msg.payload);
  }
};
