* feat(extensions): add load-time validation for auth capabilities Catch common misconfigurations (missing auth section, missing setup_url, short prompts) at startup via tracing::warn instead of silently failing at auth time. * feat(extensions): improve auth prompts, setup_url, and showAuthCard Add setup_url and descriptive prompts to channel and tool capabilities files. Fix showAuthCard in web gateway and improve extension manager auth flow messaging. * refactor(extensions): extract MIN_PROMPT_LENGTH constant in validate() Address review feedback: replace magic number 30 with a named constant for readability and maintainability.

Discord Channel for IronClaw
WASM channel for Discord integration - handle slash commands and button interactions via webhooks.
Features
- Slash Commands - Process Discord slash commands
- Button Interactions - Handle button clicks
- Thread Support - Respond in threads
- DM Support - Handle direct messages
Setup
-
Create a Discord Application at https://discord.com/developers/applications
-
Create a Bot and get the token
-
Set up Interactions URL to point to your IronClaw instance
-
Copy the Application ID and Public Key
-
Store in IronClaw secrets:
ironclaw secret set discord_bot_token YOUR_BOT_TOKENNote: The
discord_bot_tokensecret is the only value read directly by this Discord channel WASM component. Thediscord_app_idanddiscord_public_keysecrets are used by the IronClaw host (for example, to verify Discord interaction signatures and manage slash command registration) and are not accessed from the WASM module itself.
Discord Configuration
Register Slash Commands
curl -X POST \
-H "Authorization: Bot YOUR_BOT_TOKEN" \
-H "Content-Type: application/json" \
https://discord.com/api/v10/applications/YOUR_APP_ID/commands \
-d '{
"name": "ask",
"description": "Ask the AI agent",
"options": [{
"name": "question",
"description": "Your question",
"type": 3,
"required": true
}]
}'
Set Interactions Endpoint
In your Discord app settings, set:
- Interactions Endpoint URL:
https://your-ironclaw.com/webhook/discord
Usage Examples
Slash Command
User types: /ask question: What is the weather?
The agent receives:
User: @username
Content: /ask question: What is the weather?
Button Click
When a user clicks a button in a message, the agent receives:
User: @username
Content: [Button clicked] Original message content
Error Handling
If an internal error occurs (e.g., metadata serialization failure), the tool attempts to send an ephemeral message to the user:
❌ Internal Error: Failed to process command metadata.
Check the host logs for detailed error information.
Advanced Usage
Embeds
To send embeds, include an embeds array in the metadata_json field of the agent's response. The structure should match the Discord API embed object.
Troubleshooting
"Invalid Signature"
- Check that
discord_public_keyis set correctly in IronClaw secrets. - This validation happens on the host before reaching the WASM.
"401 Unauthorized"
- Check that
discord_bot_tokenis set correctly in IronClaw secrets. - Ensure the bot is added to the server.
"Interaction Failed"
- The interaction might have timed out (Discord requires a response within 3 seconds).
- The
interactions_endpoint_urlmight be unreachable.
