datasette-agent 0.1a3

Datasette Agent 0.1a3, released on May 21, 2026, introduces enhanced agent loop stability and a plugin system for custom tool definitions. The update allows developers to register new tools via plugins, enabling the agent to perform domain-specific actions like querying external APIs or running custom SQL transformations. This version also includes bug fixes for long-running agent sessions and improved error handling. The plugin hooks are documented in the project's README, with examples for adding tools such as web scraping or data validation. Simon Willison's announcement highlights the agent's growing maturity for automated data tasks, though it remains in alpha (0.1a3). The release is available on PyPI and GitHub, with no breaking changes from previous alphas.
