Routing Implementation (zoom-general)

This reference provides a concrete implementation model for routing a complex developer query from zoom-general to specialized skills.

Runtime Assumptions

• Runtime: Node.js 18+.
• Language: TypeScript 5+.
• Input: free-form developer prompt.
• Output: deterministic handoff contract with primary skill, chained skills, rationale, and follow-up questions (if required).

Error Handling Expectations

• Unknown/low-signal prompts route to zoom-general with one clarifying question.
• Conflicting signals do not fail hard; produce warnings and preserve guardrails.
• Routing should be deterministic for the same normalized prompt.
