Skill activation triggers

Run Architecture when topology or quality-attribute scenarios are undecided. Run Security when trust boundaries or threat notes are missing. Hand off to Planning only after the ADR rejects alternatives explicitly.

Verification that skills worked

• ADR records at least one rejected alternative with rationale
• Quality-attribute scenarios are named, not implied
• Trust boundaries appear before implementation planning

Changelog

• 1.3 (2026-07-29): Architecture skill activation and verification rewritten for this envelope.
