Core Concepts

A Work is the unit you create, run, and share. Services give it concrete capabilities. The Harness understands the workspace and uses its tools and Services to perform tasks.

Concept	A concrete example	What to read
Work	A Kanban workspace with source files, board data, a running application, and conversation history.	Work
Service	The container running the board's web application and API.	Service
Harness	The layer that uses models and tools to build the board, inspect its state, and make changes.	Harness

How they fit together

The Work contains Services, data, tools, configuration, and its Harness. The Harness understands and operates those resources. Core manages the Work's lifecycle and Docker resources. Desktop / CLI gives you access to the Work.

The portable unit includes the runnable environment and its durable state. A conversation can explain a task; a Work also retains the files, Service definitions, fixed images, and context needed to continue it.

The technical specifications describe the current implementation and its boundaries.
