Architecture Spec Writer

Category: Content  ·  Sub-category: content-misc  ·  Last updated:
Write a concrete architecture spec, design doc, or tech spec for an already chosen software architecture or technical direction. Trigger when the user asks to write a design doc, tech spec, architecture spec, implementation spec, or phrases like "собери design doc", "напиши tech spec", "оформи архитектуру в документ", "сделай инженерный спек", or similar. The document must act as an engineering contract for implementation: define the goal, non-goals, invariants, interfaces, data flow, dependencies, failure modes, rollout plan, observability, validation plan, and open questions. Keep it concrete and implementation-oriented. Do not produce corporate filler, vague future-proofing, or decorative sections with no execution value. Do not use for architecture option comparison, generic brainstorming, product requirements docs, or a detailed milestone plan after the design is already fixed.
