To turn feature specifications into phased implementation plans, run the planning process on a prepared feature spec to generate concrete technical milestones. It validates inputs against a standard plan template and loads context from your constitution.md to guide architecture and delivery.

Generating an implementation plan from a spec produces artifacts like research.md, data-model.md, contracts, and quickstart.md. These files support development and onboarding by documenting architecture, technology stack choices, and phased delivery milestones.

Yes, generating phased technical plans for software projects requires a compatible IMPL_PLAN template. The planning process validates your feature spec against this template and loads context from .specify/memory/constitution.md before producing the implementation plan.

Spec-driven planning handles architecture and technology stack decisions by translating detailed feature specifications into actionable, phased technical plans. It updates agent context throughout the process, ensuring architecture choices and tech decisions are documented in the generated artifacts.

The best way to reduce ambiguity in software feature delivery milestones is to use a spec-driven workflow that transforms detailed specifications into actionable technical plans. This process validates inputs and produces structured artifacts like data-model.md and contracts.
