Architecture
Application shape, tenancy, authorization, billing boundaries, public identity, frontend ownership, and where domain behavior lives.
Free Rails architecture checkup
See what your Rails app is teaching your coding agent.
A mature Rails app already contains years of decisions about tenancy, authorization, jobs, billing, frontend conventions, integrations, testing, and operations. Coding agents learn from those decisions whether you documented them or not.
This checkup gives a repo-aware agent one job: map the architecture, find conflicting precedent and missing decisions, separate real correctness or security risks from stylistic preference, and show where the next feature still has to guess.
Run the Architecture Checkup No signup required. Nothing from your repository is sent to Rails Baseline.
What it looks for
Not whether your app matches somebody else’s stack.
If your app uses CanCanCan instead of Pundit, Sidekiq instead of Solid Queue, or React instead of Hotwire, that is not a finding by itself. The checkup looks for whether your application has a coherent answer, whether that answer is safe, and whether an agent can discover it from the repository.
Agent context
AGENTS.md, architecture docs, local precedent, contracts, recipes, and places where the code says two different things.
Risk
Tenant isolation, permissions, secrets, external calls, retries, idempotency, error reporting, and other places inconsistency becomes a correctness problem.
Next steps
What to leave alone, what to document, what to normalize when touched, and what deserves deliberate remediation now.
