SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Produces and validates phase plans to ensure builders have a clear, verifiable route from goals to actionable tasks, reducing miscommunication and rework.

Core Features & Use Cases

  • Planner-Checker loop: drafts a PLAN.md, validates against gates, and iterates up to a maximum of 3 cycles.
  • DAG-based task ordering: enforces dependency order to prevent circular or out-of-sequence work.
  • Artifact generation: creates PLAN.md and LEARNINGS.md (when applicable) to capture decisions and learnings for future phases.

Quick Start

Initiate a planning cycle for the target phase by running the planner-checker workflow to produce and verify a validated PLAN.md.

FAQPage Schema
How do I generate phase plans and verify dependencies before starting a build?▼

To generate phase plans and verify dependencies, use a planner-checker workflow that drafts a PLAN.md and validates it against risk and verification gates. This enforces DAG-based task ordering to prevent out-of-sequence work.

What is a planner-checker loop for phase planning and how does it work?▼

A planner-checker loop for phase planning is an iterative cycle that drafts a plan and validates it against dependency and risk gates. It automatically repeats up to 3 cycles to resolve errors and produce a verified PLAN.md.

How do I prevent circular dependencies when mapping out project phases?▼

To prevent circular dependencies during project phase mapping, enforce DAG-based task ordering. This validates dependency order and ensures tasks are sequenced correctly before build execution.

Does this phase planning approach support risk assessment and gate checks?▼

Yes, this phase planning approach integrates risk assessment and gate checks into its validation workflow. The checker validates drafted plans against these gates before allowing phase progression.

What artifacts are generated when validating phase plans?▼

Validating phase plans generates a PLAN.md artifact to guide the build and a LEARNINGS.md file. The LEARNINGS.md captures decisions and insights from the planning process for future phase reference.

What are the limitations of the planner-checker iteration cycle?▼

The main limitation of the planner-checker iteration cycle is a maximum of 3 automated loops. If a PLAN.md cannot pass dependency, risk, and verification gates within 3 cycles, manual intervention is required.
