SDD Domain Skill (Orchestrator)

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

Philosophy

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

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

Architecture

This skill orchestrates 2 sub-skills:

Sub-Skill	Scope	Methodologies
faion-sdd-planning	Specs, design docs, impl-plans, tasks, templates, workflows	28
faion-sdd-execution	Quality gates, reflexion, patterns, memory, code review, context	20

Total: 48 methodologies

Workflow Overview

CONSTITUTION → SPEC → DESIGN → IMPL-PLAN → TASKS → EXECUTE → DONE
      |          |        |          |          |         |        |
   project    feature  technical   100k rule   atomic   agent    learn
   principles  intent   approach   compliance   units  execution reflect

When to Use Which Sub-Skill

Use faion-sdd-planning for:

• Writing specifications (WHAT + WHY)
• Creating design documents (HOW)
• Breaking down implementation plans (TASKS)
• Task creation from impl-plans
• Template usage
• Workflow navigation

Use faion-sdd-execution for:

• Task execution workflows
• Quality gate validation (L1-L6)
• Code review cycles
• Reflexion learning (PDCA)
• Pattern/mistake memory management
• Context management strategies
• Task parallelization analysis
