A guide for building Discord bots on Cloudflare Workers. Discord is a chat platform, and bots are programs that respond to messages or commands there.

Use it to connect a bot to Discord, add slash commands, receive events, configure permissions and intents, and verify incoming requests.

It brings the Discord setup, security checks, permissions, and Cloudflare deployment details together in one workflow.

discord-bot — Skill for OpenCode by rianvdm

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add rianvdm/product-ai-public --skill discord-bot

Clone the repo

git clone --depth 1 https://github.com/rianvdm/product-ai-public

Made for: OpenCode.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00040	$0.01941
Opus 5	$0.00020	$0.00971
Sonnet 5	$0.00008	$0.00388
Haiku 4.5	$0.00004	$0.00194

Security

Grade A, and why

discord-bot scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Discord Bot Development

Use this skill when working on Discord bots, Discord API integration, bot setup/configuration, or slash command registration. Triggered by mentions of Discord bots, Discord Developer Portal, Discord API, slash commands, Gateway, or Interactions Endpoint.

Critical Rule: Always Web Search

The Discord Developer Portal UI changes frequently. Do NOT rely on pre-trained knowledge for:

Where settings are located in the Developer Portal
OAuth2 flow steps
Bot permission configuration
Interactions Endpoint setup
Install link generation

Always web search first for any Developer Portal instructions. Use queries like:

Discord Developer Portal [specific task] 2026 (include the current year)
Discord bot setup [specific feature] latest

If search results are older than 6 months, note this to the user and suggest they verify in the portal.

Discord Bot Architecture on Cloudflare Workers

Two models for receiving Discord events:

Interactions Endpoint (HTTP)

Discord POSTs slash commands and component interactions to your Worker URL
No persistent connection needed — pure request/response
Set the URL in Developer Portal → General Information → Interactions Endpoint URL
Requires Ed25519 signature verification on every request (discord-interactions npm package)
Supports: slash commands, buttons, select menus, modals, autocomplete

Gateway (WebSocket)

Persistent WebSocket connection to wss://gateway.discord.gg
Required for: reaction events, message events, presence, voice state, typing indicators
On Cloudflare Workers: use a Durable Object with new WebSocket(url) for the outbound connection
NOT fetch() with Upgrade: websocket — that doesn't work for wss:// URLs
DO won't hibernate while outbound WS is open — use alarm-based keepalive (30s interval)
Deploys evict the DO; alarm reconnects within ~30 seconds

Which Do You Need?

Feature	Interactions Endpoint	Gateway
Slash commands	Yes	Not needed
Message reactions	No	Required
Message content	No	Required (with intent)
Typing indicators	No	Required
Presence updates	No	Required
Voice state	No	Required

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
