- Provides AGENTS.md and architectural contracts giving AI agents local precedent for common patterns
- Optimizes for code quality and consistency of future extensions, not just initial scaffolding avoidance
- Stays true to Rails conventions without abstraction layers—familiar to both developers and AI agents

Frequently asked questions about Rails Baseline
How is this different from other Rails starter kits?
Rails Baseline includes architectural contracts, agent instructions, and recipes alongside code. It optimizes for how well the next 100,000 lines get written, not just features you avoid building.
Why is this useful for AI coding agents?
Agents excel at continuing strong patterns. Rails Baseline provides explicit local precedent (AGENTS.md, contracts, examples) so prompts can focus on the feature, not reinventing application architecture.
Does this require learning a new framework?
No. Rails Baseline is still vanilla Rails. It uses standard routing, forms, Turbo for interactivity, and optional React islands—just with documented architectural patterns.
