openclaw - 💡(How to fix) Fix Feishu streaming card: allow custom header title instead of hardcoded session name [1 participants]

Problem

When using Feishu channel with renderMode: "card" (streaming cards), the card header always shows the internal session/agent identifier (e.g., "main") as the title. This is not meaningful to end users and looks like a debug label.

Expected Behavior

Allow customizing the streaming card header title via configuration, for example:

// openclaw.json
{
  "channels": {
    "feishu": {
      "cardHeader": {
        "title": "小爪",           // custom display name
        "template": "blue"        // color theme
      }
    }
  }
}

Or per-agent:

{
  "agents": {
    "defaults": {
      "displayName": "小爪"
    }
  }
}

Current Behavior

The StreamingCard class in extensions/feishu/src/streaming-card.ts sets the header title from options.header.title, which is populated with the agent/session ID (e.g., "main"). There is no user-facing config to override this.

Use Case

• Users deploy OpenClaw as a team assistant bot in Feishu group chats
• The card header is visible to all group members
• Showing "main" looks unprofessional; a custom name (bot name, task description, etc.) would be much better

Suggested Implementation

In streaming-card.ts around line 184-188, fall back to a configured display name when options.header.title is the raw session ID:

const displayTitle = config.channels?.feishu?.cardHeader?.title 
  ?? options?.header?.title 
  ?? agentConfig?.displayName
  ?? "OpenClaw";

Environment

• OpenClaw version: 2026.3.23-2
• Channel: Feishu (websocket mode)
• renderMode: card
• streaming: true
