Datasette Apps 0.3a0 adds LLM-agent app and query controls
Datasette Apps 0.3a0 adds support for hosting and editing custom HTML applications inside Datasette. The release also improves its LLM-assisted workflow through Datasette Agent: users can tag apps in chat messages with #, while new agent tools manage which stored queries an app may call. The release announcement says write-query access requires user approval, and app creation checks that referenced queries exist and are viewable by the user.
This niche alpha release gives Datasette Agent more concrete tools for creating custom applications while adding permission checks around the stored queries those apps can access.
