What it is and what it does
Arcade Core is a foundational library for the Arcade platform ecosystem. It provides the core abstractions and utilities that Arcade toolkits build upon: a tool catalog system for discovering and organizing tools, configuration and schema validation via pydantic, authentication and authorization primitives, comprehensive error types, and observability features including telemetry. The package is designed to be installed alongside Arcade toolkit packages that extend its capabilities with domain-specific tools.
The library handles the plumbing that Arcade toolkits need: loading toolkit modules, managing tool metadata, validating configurations, and providing common utilities. It depends on httpx for HTTP operations, loguru for logging, pydantic for schema validation, pyjwt for authentication tokens, and posthog for telemetry, among others. It targets modern Python versions and is marked production-stable.
Use it for
- Building or extending Arcade platform toolkits by providing the core toolkit loading and catalog infrastructure.
- Implementing authentication and authorization flows using the built-in auth provider utilities.
- Standardizing configuration and schema validation across Arcade ecosystem packages via pydantic integration.
- Adding observability and telemetry to Arcade-based applications through the telemetry utilities.
- Managing and organizing tool discovery in applications that use multiple Arcade toolkit packages.
