openclaw - 💡(How to fix) Fix [Bug] Kimi web_search does not return citations/source URLs

Description

When using Kimi as the web_search provider, the search results do not include citations or source URLs. The response contains citationsUnavailable: true, making it impossible to verify the sources or provide proper attribution.

Environment

• OpenClaw version: 2026.3.13 (61d171a)
• Kimi model: kimi-k2.6
• Kimi API baseUrl: https://api.moonshot.cn/v1

Configuration

{
  \"tools\": {
    \"web\": {
      \"search\": {
        \"enabled\": true,
        \"provider\": \"kimi\",
        \"kimi\": {
          \"model\": \"kimi-k2.6\",
          \"baseUrl\": \"https://api.moonshot.cn/v1\"
        }
      }
    }
  }
}

Expected Behavior

Kimi $web_search should return source URLs/citations like other search providers (e.g., Tavily, Brave).

Actual Behavior

Response shows citationsUnavailable: true and no source URLs are provided in the search results.

Additional Context

This makes it difficult to verify search results and provide proper source attribution to users. Tavily search provider properly includes citations.
