SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prevents execution from running ahead of unresolved design by planning the next phase with explicit entry/exit criteria and verification expectations.

Core Features & Use Cases

  • Design-gated planning: Ensures the plan only proceeds when the design revision is present and aligned to the current ask, avoiding speculative phase creation.
  • Execution-ready IP refinement: Converts intent into concrete phase objectives, success criteria, and verification expectations mapped to the work.
  • Next phase sheet creation and setup: Creates the next phase and updates it with tasks, assumptions/constraints, and VT/VA/VH-style verification steps.
  • Policy ambiguity escalation: Routes complex or ambiguous situations to consultation before execution.

Quick Start

Ask your agent to run the plan-phases flow for DE-, DR-, and IP- artifacts so it can produce the next phase sheet with concrete tasks and done criteria.

FAQPage Schema
How do I prevent execution from running ahead of unresolved design in spec-driven development?

Spec-driven design gating prevents execution drift by planning the next phase with explicit entry and exit criteria, ensuring the execution-ready IP only proceeds when the design revision aligns with the current ask.

What's the best way to generate execution-ready phase plans with verification criteria?

Generating an execution-ready IP refines design intent into concrete phase objectives, success criteria, and VT/VA/VH verification expectations, creating a next phase sheet populated with tasks and done criteria before handoff.

Do I need design revision artifacts to start phase planning?

Phase planning requires DE- and IP- artifacts to exist, while the DR- artifact can optionally be missing or stale, allowing the workflow to proceed by reconciling available inputs and enforcing design-gating rules.

How does agent orchestration handle policy ambiguity during phase planning?

Agent orchestration routes complex or ambiguous policy situations to consultation before execution, escalating issues rather than guessing, ensuring the generated phase plan avoids speculative creation against unresolved design.

Can I automate next phase sheet creation and task updates in workflow automation?

Workflow automation creates the next phase sheet via the phase creation command, automatically updating it with assumptions, constraints, tasks, and VT/VA/VH-style verification steps to produce an execution-ready handoff.
