Claudia

A task management system built for AI agents.

Official website: https://claudiacli.com/

Claudia provides structured task tracking with a Model Context Protocol (MCP) server, enabling AI assistants like Claude to manage their own work through hierarchical tasks, dependencies, sprints, and acceptance criteria verification.

Why Claudia?

AI agents need a way to:

• Track progress across complex, multi-step tasks
• Coordinate when multiple agents work on the same project
• Remember context between sessions (64KB JSON storage per task)
• Verify work against acceptance criteria before completion
• Organize work into sprints and project hierarchies

Claudia provides all of this through both a CLI and MCP server interface.

Quick Start

# Install Bun if you haven't already
curl -fsSL https://bun.sh/install | bash

# Clone and build
git clone https://github.com/yuvalsuede/claudia.git
cd claudia
bun install
bun run build

# Initialize and start using
./claudia db init
./claudia task create --title "My first task"
./claudia task list

Try the Demo

See Claudia in action with sample data:

# Seed demo project with sample tasks and sprints
bun run seed:demo

# Open the web dashboard
./claudia @@ --port 3333

Then open http://localhost:3333 in your browser to explore the kanban board and sprint views.

MCP Server Integration

Start the MCP server for use with Claude Code:

claudia mcp

Claude Code Configuration

Add to .mcp.json in your project root:

{
  "mcpServers": {
    "claudia": {
      "command": "/path/to/claudia",
      "args": ["mcp"]
    }
  }
}

Or for development (without building):

{
  "mcpServers": {
    "claudia": {
      "command": "bun",
      "args": ["run", "/path/to/claudia/src/mcp/server.ts"],
      "cwd": "/path/to/claudia"
    }
  }
}

After adding the config, restart Claude Code to connect.

Task Workflow

┌─────────┐     ┌─────────────┐     ┌──────────────┐     ┌───────────┐
│ pending │────▶│ in_progress │────▶│ verification │────▶│ completed │
└─────────┘     └─────────────┘     └──────────────┘     └───────────┘
     │                │                    │                    │
     ▼                ▼                    ▼                    ▼
┌─────────┐                         ┌──────────┐
│ blocked │                         │ archived │ (terminal)
└─────────┘                         └──────────┘

Valid transitions:

• pending → in_progress, blocked, archived
• in_progress → pending, verification, completed, blocked, archived
• verification → in_progress, completed, blocked, archived
• blocked → pending, in_progress, archived
• completed → in_progress, archived
• archived → (terminal state)

Tasks can skip verification if no acceptance criteria are defined.

Multi-Agent Coordination

Claudia supports multiple AI agents working concurrently on the same project.

Task Claiming

// Claim before working
const result = await task_claim({ task_id: "uuid", agent_id: "agent-1" });
if (result.success) {
  // Task is yours - proceed
} else {
  // Already claimed by another agent
}

// Release when done or on failure
await task_release({ task_id: "uuid", agent_id: "agent-1" });

Optimistic Locking

// Read task first
const task = await task_read({ id: "uuid" });

// Update with version check
await task_update({
  id: task.id,
  title: "Updated",
  version: task.version  // Fails if modified by another agent
});

Recommended Pattern

1. task_ready - List tasks with satisfied dependencies
2. task_claim - Atomically reserve a task
3. task_transition - Move to in_progress
4. task_context_merge - Save progress
5. task_transition - Move to completed
6. On failure: task_release - Let another agent retry

Configuration
