Discord Bot

A Discord slash-command bot running on Cloudflare Workers. The /llm command acknowledges interactions immediately, generates an answer with Workers AI, and uses Cloudflare Workflows to deliver the deferred response reliably.

How it works

1. The Worker verifies Discord's Ed25519 request signature and rejects stale requests.
2. A per-user KV rate limit protects Workers AI inference from sustained abuse.
3. Discord receives a deferred response before its interaction deadline.
4. Workers AI generates the answer outside the request path.
5. A Workflow patches the original Discord message, with retries and a ten-minute timeout.

The model is selected with AI_MODEL and defaults to @cf/qwen/qwen3.8-27b. Responses are capped at Discord's 2,000-character message limit.

Development

npm install
npm run dev

Set the Discord application public key for local or deployed request verification:

npx wrangler secret put DISCORD_PUBLIC_KEY

The Worker also needs the AI, WORKFLOW, and RATE_LIMITS bindings declared in wrangler.toml.

Checks

npm run typecheck
npm run lint
npm run test:run
npm run format:check

Deploy

npm run deploy

After deployment, set the Worker's URL as the Discord application's Interactions Endpoint URL.
