Plain Markdown
Playbooks are standard .md files. No proprietary format, no special editor required. Write workflows in the same tool you write everything else.
PLAYBOOK.md Docs
The open specification for multi-step AI workflows, written in plain markdown. Define steps, inputs, branching, and tool integrations in a single .md file.
Multi-Step Workflows
Define sequential steps that each perform a single unit of work. Each step receives the accumulated context of all prior steps automatically.
Branching and Logic
Route execution conditionally based on inputs or AI outputs. Build adaptive workflows that respond to real-time classification and decisions.
Tool Agnostic
PLAYBOOK.md is a portable format. Any implementation that conforms to the spec can parse and execute playbooks, regardless of the AI provider or runtime.
