Identify state, request shape, trust boundaries, expected scale, team capacity, and operational constraints. Respect existing stack decisions.
Recommend an architecture with its costs, alternatives where meaningful, and conditions for revisiting it. Consult architecture patterns as needed.
Include a concrete folder tree, entry points, domain/data boundaries, configuration, and test locations. Use the folder template if useful.
Recommend only needed dependencies, checking current primary documentation for compatibility and maintenance. The catalog is a starting point, not proof of current versions. Explain replacement cost.
Identify security/data-protection decisions and unresolved risks. Incorporate an existing security plan; request specialist input only when it changes the design. No mandatory agent handoff.
When specifications or milestones are requested, use spec and plan with the agreed requirements. Include ordered tasks, acceptance criteria, dependencies, and a first vertical slice.

Default output: constructor-output/architecture-doc.md, with sections for needs, architecture, folder structure, dependencies, security, and optional plan. Use the architecture template selectively. Split documents only for independent consumption, size, or user preference. Existing separate output files remain supported inputs; do not rewrite them just for consistency. Implementation is a separate action governed by the user's task.
