Read, write, & run files

Query your SQLite databases & Blob storage
Read & write environment variables
Read logs
Read & configure cron jobs

System prompt

Our system prompt is public. It provides Townie full context on how to use the Val Town platform—e.g. available tools, the Val Town runtime, our standard library, different types of vals, etc.

Keyboard shortcuts & slash commands

You can open Townie with ⌘J. The following slash commands are available:

/cost Show estimated cost and usage
/context Show context window usage
/compact Summarize older messages to save context
/clear Start a new chat

History & version control

You can view your Townie chat history in settings to read and continue old chats.

As when coding without AI, you can use Val Town’s versioning and collaboration tools like branching, remixing, PRs, and version history to safely work with Townie.
