• New tool, execute_write_sql, which requests user approval and then writes to a database - taking user permissions into account. #27

I added a mechanism for asking user approval in datasette agent 0.2a0. The new execute_write_sql tool can now prompt the user for all kinds of useful operations. Here's an example where I add some pelican sightings to my pelican_sightings table:

The new version also enhances the datasette agent chat terminal mode to support approvals, and adds several new options including --unsafe mode for auto-approving them:

• datasette agent chat can execute tools that require user approval. #30
• Three new options for datasette agent chat - --root to run as root, --yes to approve all ask user questions, and --unsafe for both.
• Tools can now provide plain text alternatives to HTML, for display in the datasette agent chat CLI. #31

The datasette agent chat content.db -m gpt-5.5 --unsafe command can now be used to chat directly with a specific database and directly modify it through prompts like "create a notes table", "add a note about X" etc.
