## Summary

Datasette Apps 0.3a0 lets users tag apps in Datasette Agent chat by typing #, with autocomplete from apps they can view. New app_add_stored_queries() and app_remove_stored_queries() tools let the agent manage which stored queries an app can call, and granting a write query requires user approval. app_create() now checks that each requested stored query exists and is viewable before creating an app.
