Technical Design Document Generator (Interactive)

Goal

Produce a production-grade Technical Design Document (TDD) and its supporting Architecture Decision Records (ADRs, MADR format) — thorough enough to guide real implementation and traceable enough to justify itself to a future maintainer. This is not a light draft generator.

This skill is conversational, not one-shot. Never generate the full TDD in a single pass. Walk the user through each architecture decision one at a time, present real alternatives with trade-offs, ask which one they choose (or if they have a different idea), and only then write the ADR reflecting their actual decision. An ADR the agent decided alone, without the user's input, is a failure of this skill.
