SDD Planning Sub-Skill

Documentation planning phase of Specification-Driven Development.

Communication: User's language. Docs/code: English.

Discovery Questions

questions:
  - question: "Which SDD phase are you in?"
    options:
      - label: "Writing specification"
        description: "Use writing-specifications, spec-structure"
      - label: "Creating design doc"
        description: "Use design-doc-structure, design-doc-writing-process"
      - label: "Breaking down into tasks"
        description: "Use writing-implementation-plans, task-creation-principles"
      - label: "Setting up SDD workflow"
        description: "Use workflows, templates"

  - question: "Do you have existing SDD documentation?"
    options:
      - label: "Yes, following SDD"
        description: "Continue with established patterns"
      - label: "Partial/inconsistent"
        description: "Standardize using templates"
      - label: "No, starting fresh"
        description: "Start with spec-structure, templates"

  - question: "What's your task complexity?"
    options:
      - label: "Simple features (<50k tokens)"
        description: "Standard task breakdown"
      - label: "Complex features (>100k tokens)"
        description: "Apply impl-plan-100k-rule, split features"

Philosophy

"Intent is the source of truth" - specification is the main artifact, code is implementation.

No Time Estimates: Use complexity (Low/Medium/High) + token estimates (~Xk).

Scope

This sub-skill handles:

  • Writing specifications (WHAT + WHY)
  • Creating design documents (HOW)
  • Breaking down implementation plans (TASKS)
  • Task creation and templating
  • Workflow documentation
