SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Execute pre-planned tasks end-to-end by orchestrating subtasks through a four-phase workflow (init, execute, verify, approve).

Core Features & Use Cases

  • Phase-based subtask orchestration: init, execute, verify, approve, with wave-based sequencing.
  • Enforces plan.md as truth source and audit by validator/auditor before completion.
  • Works with pre-defined subtasks stored in .tasks/{TASK-ID}/subtasks and generates incremental tasks for fixes if needed.

Quick Start

Provide a task folder containing plan.md and subtasks/index.md, then run the act skill to execute the pre-planned task workflow.

FAQPage Schema
How do I automate task execution from a pre-planned task list?

You can automate task execution by orchestrating subtasks through a four-phase workflow: init, execute, verify, and approve. This approach requires a plan.md file as the truth source to ensure strict adherence to your existing sequential task plan.

What is a phase-workflow orchestrator for subtasks?

A phase-workflow orchestrator automates end-to-end execution by sequencing subtasks into waves across init, execute, verify, and approve phases. It enforces plan.md as the truth source and invokes phase-2 agents to perform work while phase-3 validators audit quality before completion.

How do I set up files to run a phase-based workflow for task execution?

To set up phase-based task execution, provide a task folder containing a plan.md file and a subtasks/index.md file. The index.md must define the sequence and agents, which the orchestrator uses to execute the workflow automatically.

How does validation work in a multi-phase task execution workflow?

Validation in a multi-phase task execution workflow occurs during the verify phase. Phase-3 validators and auditors perform final quality checks on the completed work, generating incremental fix tasks if the executed subtasks do not meet the required audit standards.

Can I use this task execution method without a predefined plan?

No, this task execution method requires a predefined plan. It enforces plan.md as the strict truth source and relies on a subtasks/index.md to define sequences and agents, meaning it cannot orchestrate tasks without pre-planning.

What happens if a subtask fails validation during execution?

If a subtask fails validation during execution, the workflow generates incremental tasks for fixes. This occurs during the verify phase, where phase-3 auditors assess quality and trigger these additional tasks to ensure the final output meets the plan's standards.
