Requests

Use this skill for inbound HTTP request parsing and validation.

Workflow

1. Type all handler parameters explicitly.
2. Use parameter helpers for headers/cookies/query aliases and constraints.
3. Validate body payloads via DTO/dataclass/msgspec/pydantic models.
4. Keep transport validation in handlers and business rules in services.

Checklist

• Avoid untyped dict request payloads when schema is known.
• Use narrow types for booleans, enums, UUIDs, and datetimes.
• Handle malformed input with deterministic 4xx responses.
