linear-webhook（Linear webhook 搜索）

Linear Webhook Skill

Enables Linear issue comment @mentions to dispatch tasks to Clawdbot agents.

How It Works

1. Comment in Linear: @mason implement user authentication or @eureka plan Q2 roadmap
2. Linear webhook fires on comment creation
3. Clawdbot receives webhook via exposed endpoint
4. Transform parses payload:

- Extracts @mason or @eureka mention - Gets issue context (title, description, labels) - Prepares task prompt

1. Routes to agent session:

- @mason → mason agent (code/implementation) - @eureka → eureka agent (planning/strategy)

1. Agent processes task and returns result
2. Result posted back as Linear comment

Setup

1. Configure Clawdbot Webhooks

Add to your config.json5:

{
  hooks: {
    enabled: true,
    token: "your-secret-token-here", // Generate with: openssl rand -base64 32
    path: "/hooks",
    transformsDir: "/home/sven/clawd-mason/skills/linear-webhook",
    mappings: [
      {
        name: "linear",
        match: {
          path: "/linear",
          method: "POST"
        },
        action: "agent",
        transform: {
          module: "./linear-transform.js",
          export: "transformLinearWebhook"
        },
        deliver: false, // Don't auto-deliver to chat - Linear comments handle responses
      }
    ]
  }
}

2. Expose Webhook Endpoint

Use Cloudflare Tunnel or Tailscale Funnel to make webhook publicly accessible:

Option A: Cloudflare Tunnel (Recommended)

# Install if needed
brew install cloudflared

# Start tunnel (replace with your domain)
cloudflared tunnel --url http://localhost:18789

Option B: Tailscale Funnel

# Enable funnel
tailscale funnel 18789

Note the public URL (e.g., https://your-tunnel.trycloudflare.com)

3. Configure Linear Webhook

1. Go to Linear Settings → API → Webhooks
2. Click "Create new webhook"
3. Set URL: https://your-tunnel.trycloudflare.com/hooks/linear
4. Add custom header: x-clawdbot-token: your-secret-token-here
5. Select events: Comment → Created
6. Save webhook

4. Test

Comment in a Linear issue:

@mason add user authentication to the login page

Expected flow:

1. Webhook fires to Clawdbot
2. Mason agent receives task
3. Mason implements or responds
4. Result posted back to Linear issue as comment

Agent Routing

• @mason → Code implementation, debugging, technical tasks
• @eureka → Planning, strategy, research, communication
• Other mentions → Ignored (not handled)

Issue Context Provided

The agent receives:

• Issue title
• Issue description
• Issue labels
• Comment text (the @mention)
• Issue URL
• Commenter name

Customization

Add More Agents

Edit linear-transform.js:

const AGENT_MENTIONS = {
  '@mason': 'mason',
  '@eureka': 'eureka',
  '@designer': 'designer', // Add your own agents
};

Change Response Behavior

Modify deliver and channel in config:

{
  deliver: true,
  channel: "telegram",
  to: "1878354815", // Your Telegram chat ID
}

This will also send agent responses to Telegram.

Security

• Never commit hook token to version control
• Use environment variables: CLAWDBOT_HOOK_TOKEN
• Verify webhook source (Linear's IP ranges if needed)
• Use HTTPS only (Cloudflare Tunnel provides this)

Troubleshooting

Webhook not firing

• Check Linear webhook logs (Settings → API → Webhooks → View logs)
• Verify tunnel is running: curl https://your-tunnel.trycloudflare.com/hooks/linear
• Check Clawdbot logs: clawdbot gateway logs

Agent not responding

• Check transform is loading: Look for errors in gateway logs
• Verify agent session exists: clawdbot sessions list
• Test transform manually: node linear-transform.js

Response not posting to Linear

• Implement Linear API comment posting in transform
• Add Linear API token to config
• See linear-transform.js for example

Linear API Access

To post comments back to Linear, you need a Linear API token:

1. Go to Linear Settings → API → Personal API keys
2. Create new token with write scope
3. Add to environment: CLAWDBOT_LINEAR_API_KEY=lin_api_...
4. Transform will use this to post responses
