This skill orchestrates the /specify phase, producing spec.md with measurable success criteria, classification flags for downstream workflows, and maximum 3 clarifications using informed guess heuristics for technical defaults.

Core responsibilities:

Parse and normalize feature input to slug format (kebab-case, no filler words)
Check roadmap integration to reuse existing context
Load project documentation context (docs/project/) to prevent hallucination
Classify feature with 4 flags (HAS_UI, IS_IMPROVEMENT, HAS_METRICS, HAS_DEPLOYMENT_IMPACT)
Determine research depth based on complexity (FLAG_COUNT: 0→minimal, 1→standard, ≥2→full)
Apply informed guess strategy for non-critical technical decisions
Generate ≤3 clarifications (only scope/security critical)
Write measurable success criteria (quantifiable, user-facing)
