Spec Writer

Create or refine planning artifacts when the change has moved beyond exploration.

Required Inputs

Read .spec-superflow.yaml (especially dp_0_decisions, dp_0_confirmed) and any existing planning artifacts. If dp_0_confirmed is not true, stop and route back to workflow-start for DP-0.

Config Check

Run: ssf runtime config --get artifacts.order — generate in configured order (default: proposal → specs → design → tasks). Run with artifacts.skip — skip any listed artifacts.

Artifact Roles

• proposal.md: why and scope
• specs/: required behavior (testable)
• design.md: architecture decisions and trade-offs (not line-by-line)
• tasks.md: dependency-aware implementation steps
