Variable Management And Context Passing Across Workflow Steps

via “task-level environment variable and parameter injection”

A lightweight workflow engine built the way it should be: declarative, file-based, self-contained, air-gapped ready. One binary that scales from laptop to distributed cluster. Used as a sovereign AI-agent orchestration infrastructure.

Unique: Task-level variable injection with support for output chaining — variables can be defined globally, per-task, or captured from previous task outputs, enabling parameterized workflows without hardcoding environment-specific values

vs others: Simpler than Airflow's XCom (no database required) and more flexible than shell script parameter passing because variables are managed at the workflow level with built-in substitution
