Arsumbris: Malleable, agent-native IDE for typed knowledge

Arsumbris released an early alpha of its agent-native IDE for typed knowledge, currently macOS-only, built on a type engine and extensible agent framework that indexes cross-repo markdown and YAML files into a typed, queryable live graph. The IDE connects to agent harnesses through MCP and lets users and agents build tools, add views, and modify the app with the same primitives and SDKs used to build it. The release warns of bugs and breaking changes and notes it runs code on the user's machine with no sandboxing yet.

Early alpha. Expect breaking changes. Macos only for now. A malleable, agent-native IDE for typed knowledge. Built on a type engine and an extensible agent framework. Knowledge, types, skills, tools and UI components live together in composable repos. Repos can depend on each other, letting you reuse knowledge and capabilities across projects. The engine reads them as one typed graph, checks fields and references and gives agents diagnostics they can act on. Connect your agent harness through MCP. You and your agent can build tools, add views and modify the app with the same primitives and SDKs we used to build it. Paste the following to your agent: Please help me install Ars Umbris. 1 Create two folders if they do not already exist: - ~/arsumbris/ will hold multiple repositories. - ~/.arsumbris/ will hold configurations. 2 Clone the entry-point repository: git clone https://github.com/arsumbris/arsumbris.git ~/arsumbris/arsumbris If that destination already exists, inspect it before proceeding; do not overwrite it. 3 Read ~/arsumbris/arsumbris/INSTALL.md and follow its current setup process. Check prerequisites and explain any changes needed on my machine before making them. The cross-repo graph engine over a typed file substrate. Indexes the cross-repo file substrate, turning it into a typed, queryable, live graph. Implements a custom typing language for markdown and yaml files. See au-engine.md https://github.com/arsumbris/arsumbris/blob/main/au-engine.md Electron host application that mounts typed projections views over the graph Config driven compositions over typed data. Editable and drivable by humans and agents. See au-host.md https://github.com/arsumbris/arsumbris/blob/main/au-host.md An extensible agent layer that provides typed tools and skills via mcp. Interfaces with your harness of choice through adapters. See au-mcp.md https://github.com/arsumbris/arsumbris/blob/main/au-mcp.md See INSTALL.md https://github.com/arsumbris/arsumbris/blob/main/INSTALL.md for what to install, in which order. Early alpha release, under active development. Expect bugs and breaking changes. Runs code on your machine, with no sandboxing yet.
