MVP technical design

Read the agreed requirements and reuse Handoff Context. Inspect an existing project's stack and relevant implementation before proposing replacements. Ask only for consequential choices that remain unresolved; a known answer does not need another confirmation echo.

Describe the architecture needed for the core journey: component/service boundaries, data ownership, integration contracts, deployment target, and relevant failure behavior. Prefer the smallest design that meets requirements. Add auth, storage, infrastructure, AI, or paid services only when justified. Verify changing vendor details from the installed code or official sources.

Record meaningful tradeoffs, compatibility constraints, migration/recovery requirements where applicable, and how the result will be checked. Distinguish local test operations from external sends, production writes, and deployments. Keep secrets out of generated documents. Do not assign broad tool permissions or require a team of agents to execute an ordinary implementation.
