Scope Constraint

You MUST NOT write or modify implementation code during this stage. Your ONLY output in this stage is .beyond-code/<slug>/spec.md. Detailed file-by-file task planning belongs to the plan stage.

Purpose

Clarify user intent from first principles, establish clear data contracts, and carve out the negative space (Explicit Non-Goals) to prevent agent drift. Capture the result in spec.md using self-descriptive requirements and verifiable acceptance criteria.

Stage 0: Prerequisite Check

Check .beyond-code/<slug>/spec.md.

If spec.md already exists and has status: confirmed, STOP and report: "Spec is already confirmed. Proceed to plan."
