Thanks for your interest in contributing! Catnip is a Discord bot template built for Val Town's serverless Deno runtime.

1. Fork and clone the repository
2. Copy .env.example to .env and fill in your Discord application credentials
3. Install Deno if you don't have it

deno test --allow-env --allow-net --no-check

All 1621 tests across 126 files should pass. Tests use mock modules for SQLite, blob storage, and Val Town utilities (see test/_mocks/). See the README for a full coverage breakdown.

1. Create a new file in discord/interactions/commands/
2. Use defineCommand() to declare the command and its handler
3. Register the component handler if needed in discord/interactions/components/
4. Run discover + register via the admin endpoints

See the README for a full walkthrough with examples.

• TypeScript with Deno conventions
• No external dependencies beyond Val Town standard libraries and Deno std
• Use UserFacingError for errors shown to Discord users
• Use createLogger() instead of console.log for production logging
• Parameterize all SQL queries — never interpolate user input
• Use kv.update() or kv.claimUpdate() for atomic mutations

• Keep changes focused — one feature or fix per PR
• Include tests for new commands or behavior changes
• Make sure all existing tests still pass
• Update the README if you add commands, env vars, or endpoints
