DominikTobureto Architecture Review
Design the smallest architecture that can survive the next real change.
Grok Build Mode
- Start in Plan Mode. Architecture work should not begin with edits.
- Use subagents for parallel discovery:
domain: core entities, use cases, invariants.data: persistence, schemas, migrations, ownership.interfaces: APIs, UI boundaries, jobs, integrations.risk: coupling, circular dependencies, deployment constraints.
- Arena-style design: compare 2-3 architecture options and rank by reversibility, simplicity, and testability.
- Human-in-the-loop: ask for approval before introducing new layers, packages, services, or dependencies.
Workflow
- Clarify the product/job-to-be-done.
- Map current modules and data flow.
- Identify constraints: runtime, team, deploy, scale, compliance.
- Propose options:
- minimal change;
- modular boundary;
- larger redesign if justified.
- Recommend one path with migration steps.
- Define tests and observability needed.
Architecture Rules
- Prefer modular boundaries over premature microservices.
- Keep dependency direction explicit.
- Put business rules where they can be tested without infrastructure.
- Avoid abstract factories/layers unless they remove real coupling.
- Write an ADR for major choices.
Example Prompts
Use architecture-review. Compare clean/hexagonal/modular approaches for this feature and recommend the smallest reversible plan.
Map the current data flow with subagents, identify coupling risks, and propose an ADR before edits.
