GoKawiilShow HN: Panel gives Claude Code agents ability to build custom research panes
A new open-source tool called Panel lets developers run an AI agent alongside a research workspace containing chat, files, PDFs and Jupyter notebooks. The agent, currently built on Claude Code, can generate its own custom viewer panes on request when existing panels can't display something, and can run a literature review tool. It's an early-stage build requiring Node, pnpm, uv and a signed-in Claude Code CLI to run locally.
GoKawiil's interpretation of the reporting above, not reported fact.
This reflects a growing trend of agent-native developer tools where AI assistants aren't confined to a chat sidebar but can actively shape their own working environment and UI. Limiting full support to Claude Code (with OpenAI integration still incomplete) shows how early and vendor-dependent these agentic workspace tools remain.
- Panel combines chat, files, notebooks and PDFs into one agent-assisted workspace.
- The agent can dynamically create custom panes when built-in viewers fall short.
- Only Claude Code is fully supported; OpenAI API integration and module UIs are still missing.
