## Cadence Development
This project uses Cadence, the smart contract language for the Flow blockchain.
Refer to SKILL.md for the complete language reference.
Key conventions:
- Use `access(all)` for public access, not `pub`
- Resources use `@` prefix and must be moved with `<-`
- Always handle resources — they cannot be lost or copied
- Use capability-based access control with entitlementsContext injection
For direct API usage, inject the Cadence documentation into the system prompt:
