Plan Feature from YouTrack

Generate a spec and optionally an implementation plan from a YouTrack card, grounded in the actual codebase.

Announce at start: "I'm using the plan-feature-from-youtrack skill to generate the [spec / spec and plan] for ."

Step 1: Determine mode and card ID

From the user's message, identify:

• Card ID — e.g. INTOP-1486, ABC-123. If none is given, ask for it before proceeding.
• Mode — infer from the user's intent:
  • spec-only → user says "spec", "describe", "write a spec", or gives no indication they want tasks/plan
  • spec-and-plan → user says "plan", "implement", "create a plan", "give me tasks", "full plan"
  • When ambiguous, default to spec-and-plan and mention what you're doing.
