TaskDef is an open-source standard for defining, tracking, and quality-assuring tasks across AI agents, humans, and platforms. It's like HTML for work - a shared schema that makes tasks portable, automatable, and interoperable.

How does TaskDef work?

TaskDef works in three steps: 1) Define tasks with shared structure including title, intent, inputs, states, QA criteria, and pricing using YAML or JSON. 2) Track and QA task runs using the TaskDef Tracker. 3) Interoperate by sending and receiving tasks across tools, workflows, and agents.

Is TaskDef free to use?

Yes, TaskDef is completely free and open-source under the MIT license. You can use it commercially, modify it, and distribute it freely.

What are the use cases for TaskDef?

TaskDef is used for AI agent orchestration, QA automation with Alt.QA integration, platform task management, and publishing reusable task templates. It's ideal for multi-agent workflows, automated testing, and enterprise task standardization.
