# Otto — Project Rules

Follow `karpathy.md` (in this directory) for all behavioral coding guidelines.

In addition:

- All user-facing text, labels, errors, README, comments and LLM prompts **must be English only**.
- Experience Modes are a first-class concept: Balanced, Cultural Explorer, Foodie, Adventurous, Relaxed, Nightlife & Vibes. The chosen mode must visibly drive candidate selection and LLM prompt weighting.
- Explicit `num_days` from the user is authoritative (use dates mainly for event filtering).
- Prefer minimal code. No premature abstractions.
- API keys stay server-side only. Never leak to client.
- Every generation must respect budget and selected days.
- When editing, trace every line directly to the plan or user request (surgical).

See the approved plan.md in the session for detailed implementation phases, verification steps, and architecture.

## Quick Commands
