SDD Next

Advance the active change set to the next phase only after verifying current-phase artifacts exist.

ae-sdd-next is the single versatile phase-transition command. For full-lane work, use it for both directions between plan and implement by delegating transition decisions to CLI guards.

Required Skills

  • spec-driven-development (state management, phase sequencing, guardrails)

Inputs

[!IMPORTANT] Resolve the active change set from workspace state first. Ask the user only when multiple change sets are present.

Instructions

  1. Load spec-driven-development and run ae sdd status [name].

  2. Identify lane and current phase.

  3. Verify required artifacts for the current phase before advancing:

    • full/​proposal: changes/<name>/​proposal.md exists.
    • full/​specs: changes/<name>/​specs/ exists and contains at least one .md spec.
    • full/​discovery: changes/<name>/​thoughts/ exists and contains at least one discovery note.
    • full/​tasks: changes/<name>/​tasks.toml exists and contains at least one task entry.
    • full/​plan: changes/<name>/​plans/ exists and contains the current task plan.
    • full/​implement: changes/<name>/​tasks.toml exists and task state is valid (no more than one in_progress task).
    • full/​reconcile: changes/<name>/​reconciliation.md exists.
    • vibe/​context and bug/​triage: changes/<name>/​context.md exists.
    • vibe/​plan and bug/​plan: changes/<name>/​plan.md exists.
    • vibe/​reconcile and bug/​reconcile: changes/<name>/​reconciliation.md exists.

  4. If artifacts are missing, do not advance. Report exactly what is missing and suggest the command to produce/​fix it.

  5. Full-lane transition behavior between plan and implement must be deterministic and delegated to CLI guards:

    • From plan, running ae sdd phase complete --next [name] advances to implement.
    • From implement, running ae sdd phase complete --next [name] is versatile:
      • tasks remaining: loop back to plan
      • tasks complete: advance to reconcile
    • Always use this single CLI transition path; do not manually branch phases in workflow command logic.

  6. If artifacts are present, advance phase by running:

    ae sdd phase complete --next [name]

  7. Report the transition result and the new phase from status output.

Success Criteria

  • Phase progression happens only after artifact checks pass.
  • Missing artifacts block progression with actionable guidance.
  • Successful progression is explicit and visible in status output.
