Show 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.
