Best practices for handling commands, validating input, and filtering messages.
When to apply
Reference these guidelines when:
- Implementing slash commands
- Validating hex strings and addresses
- Filtering message types
- Using type guards instead of type assertions
Rule categories by priority
| Priority | Category | Impact | Prefix |
|---|---|---|---|
| 1 | Validators | CRITICAL | validators- |
| 2 | Filters | HIGH | filters- |
| 3 | Type Guards | HIGH | guards- |
Quick reference
Validators (CRITICAL)
validators-hex- Use validHex() for hex string validationvalidators-address- Validate Ethereum addresses
Filters (HIGH)
filters-message-types- Filter by message typefilters-sender- Filter out self-messagesfilters-content- Check for defined content
Type Guards (HIGH)
guards-codec- Use usesCodec() instead of type assertionsguards-content-type- Use filter helpers for type safety
