Simon Willison is developing plugins for Datasette Agent to enable collaborative text editing, including features like Markdown, SQL queries, and SVG files. He introduced the base plugin *datasette-agent-edit* to streamline core editing tools for reuse across other plugins. The project was announced on June 7, 2026, with sponsorship options available for updates.

A new base plugin called datasette-agent-edit has been released to provide core text-editing tools for Datasette Agent. It aims to support upcoming plugins for tasks like collaborative Markdown editing, updating large SQL queries, and editing SVG files, drawing on the design of Claude's text editor tools. The approach centralizes these editing patterns so they can be adapted across multiple plugins rather than rebuilt each time.
