Feishu Contacts Sync

Problem

Feishu (Lark) DM messages only include the sender's open_id — no name. Group messages include Sender metadata with the name, but DMs don't. Without a lookup table, the agent will either:

• Assume all DMs are from the person in USER.md (wrong)
• Fail to identify the sender entirely

Solution

Embed the full contacts table directly in USER.md. Since workspace files are injected into the system prompt at gateway startup, the agent can match open_id from inbound metadata against the table — zero tool calls needed.

Important: open_id is per-app

Feishu open_id is scoped to each app. The same person has different open_ids across different Feishu apps. Each OpenClaw instance using a different Feishu app must pull contacts with its own app credentials.

Setup

1. Ensure Feishu app has contacts permission
