61a123a746 Add GitHub tool and Discord channel (#34)
* Add GitHub tool for IronClaw - manage repos, issues, PRs, and workflows

* Add Discord channel for IronClaw - slash commands and button interactions

* Security fixes: URL encoding, secret validation, Discord button handler

- Add URL encoding for all path segments and query parameters (P1)
- Add path segment validation to prevent path traversal
- Add secret_exists check for better error messages (P2)
- Fix http_request signature to use 5 args (P2)
- Fix Discord button handler to check member field (P2)
- Fix typo in Discord slash command format (P2)
- Add github.capabilities.json and discord.capabilities.json (Blocker)
- Add Cargo.toml for Discord channel (Blocker)
- Add limit caps (max 100) for all list operations (P3)
- Remove debug logging

* Apply Copilot review fixes

Security & Code Quality:
- Use secret_get instead of workspace_read for GitHub token
- Remove manual Authorization header (host injects via capabilities)
- Add validation for file paths (reject path traversal)
- Add validation for workflow_id and git refs
- Fix url_encode_query comment
- Add release profile optimizations to Cargo.toml files
- Fix package names to match conventions (github-tool, discord-channel)
- Add metadata fields to Cargo.toml
- Fix rate limits to be consistent (60/min, 3600/hr)
- Fix Discord user_name to filter empty global_name
- Fix Discord metadata serialization error handling
- Update Discord README to clarify which secrets are used by host vs WASM
- Better formatting for Discord command option values

* applied all PR change requests and comments

* cleaned up workspace

* Adding validation for empty path segments and event enum in GitHub tool

* addedvalidation for events and vaidation to reject empty file path in github tools and implemented safe UTF-8 trunacating

* added codegen units and updated truncating logic also update capabilities.json as requested by copilot review

* added codegen units and updated truncating logic also update capabilities.json as requested by copilot review

* fixed message trucating and remove url_encode alias, also appled all requested changes from last PR comment

# 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
1. Create a Discord Application at <https://discord.com/developers/applications>
2. Create a Bot and get the token
3. Set up Interactions URL to point to your IronClaw instance
4. Copy the Application ID and Public Key
5. Store in IronClaw secrets:
```bash
ironclaw secret set discord_bot_token YOUR_BOT_TOKEN
```
**Note:** The `discord_bot_token` secret is the only value read directly by this
Discord channel WASM component. The `discord_app_id` and `discord_public_key`
secrets 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
```bash
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:
```text
User: @username
Content: /ask question: What is the weather?
```
### Button Click
When a user clicks a button in a message, the agent receives:
```text
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:
```text
❌ 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_key` is set correctly in IronClaw secrets.
- This validation happens on the host before reaching the WASM.
### "401 Unauthorized"
- Check that `discord_bot_token` is 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_url` might be unreachable.
## Building
```bash
cd channels-src/discord
