What it does

• Agents, Skills & Sub-Agents. Build an Agent once — model, instructions, and tools — then give it reusable Skills it loads on demand and sub-agents it can delegate to.
• Built-in Tool Sets. Agents move Kanban cards, post Notifications, manage Triggers, read the web, and even build other Agents and Skills.
• MCP Support. First-class Model Context Protocol support, so Agents connect securely to local and remote data sources.
• A2A Endpoints. Expose an Agent to outside agents and chat platforms over the open A2A protocol, with a token per client and every conversation kept as an ordinary Chat.
• Sandbox. Shell and filesystem access inside an isolated, per-workspace execution environment, with pluggable Docker and SSH reference backends.
