Craft Agents — A Desktop App That Talks Back to Your APIs
Craft Agents OSS shipped on GitHub and grabbed 5,500+ stars in days, currently the fastest-rising agent-tool repo on the trending board. Built by the team behind Craft (the docs/notes app), it's a desktop application where the agent interface itself is the configuration layer.
The trick is the natural-language onboarding. You don't write a YAML to add a data source. You say "add Linear as a source" and the agent handles API discovery, credential prompts, and config. Same for GitHub, Notion, your local filesystem, any MCP server. No restart. The agent rebuilds its own toolkit while you watch. This is what Anthropic's Skills + Claude Code try to do via the file system; Craft makes it the entire UX surface.
It connects to multiple LLM providers in one app, supports MCP servers as a first-class concept, and runs as a desktop binary so the latency story is local. Apache 2.0 license. The Linear demo on the README is the kind of thing that quietly makes a Cursor-class company nervous — if a docs startup can ship a multi-provider agent shell that sets up its own integrations, the moat for purpose-built agent IDEs gets thinner.
The meta-pattern is the bigger story. Three agent-shell projects trended this week — Craft Agents, browserbase/skills, jcode — all open-sourced by companies that aren't primarily agent companies. The harness layer is starting to look like the new web framework: nobody wants to be locked in, and giving away the harness is how you keep your model/browser/cloud relevant. https://github.com/lukilabs/craft-agents-oss
