Charm Store v1

This is the first public release of Charm following our strategic pivot.

This MVP introduces the Universal Agent Contract, a specialized Cloud Runner, and the Charm Store.

Store

  • Agent Distribution: A centralized hub to publish, discover, and run AI agents without local setup.

  • Key Management: Flexible authentication system supporting both secure BYOK via client-side encryption and automatic injection of platform-managed keys for seamless integration.

  • Interactive Agent UI: A comprehensive interface featuring real-time streaming of thinking processes, live developer logs, and direct artifact downloads.

SDK & CLI

  • Unified Agent Contract: Introduced charm.yaml schema to standardize agent interfaces, inputs, and environment configurations across different sources.

  • Adapters: Added native wrappers for CrewAI, LangChain, LangGraph, and custom Python agents.

  • CLI Workflow: Released charm CLI with init, validate, run , and push commands.

Runtime

  • Dynamic Cloud Runner: An optimized sandbox that automatically provisions environments and installs dependencies based on UAC manifest.

  • Pre-installed Stack: The runtime now includes heavy libraries to ensure fast cold-starts for agents.

  • State & Memory Injection: Support for multi-turn conversations by injecting interaction history and state snapshots into the container.
