Feishu Identity Routing

Build and use a Feishu/Lark cross-app identity master for multi-agent, multi-account routing. Use when mapping the same user across different Feishu app open_id values, resolving app-specific open_id from union_id/user_id, routing outbound actions with the correct accountId, or setting up reusable identity merge/review workflows.

Use this skill when a workspace needs a reusable way to:

• merge the same human across multiple Feishu apps/accounts
• store app-local open_id under one canonical user subject
• resolve the right open_id for a target accountId / app_context
• route outbound actions correctly in multi-agent setups

What to create

Create these workspace files if missing:

• identity/feishu-user-master.json — canonical data store
• identity/feishu-user-master.md — human-readable summary

Core rules

1. One person = one subject
2. Merge by union_id first, then user_id
3. Treat open_id as app-local only
4. Before any outbound action:
   • resolve the user subject globally
   • resolve the target app/account-specific open_id
   • build the provider target from that local identity

For Feishu DM routing, use:

• accountId=<target account>
• target=user:<open_id>

Scripts

Use bundled scripts when you need deterministic updates:

• scripts/merge_feishu_identity.js — merge one record
• scripts/merge_feishu_identity_batch.js — merge many records
• scripts/review_feishu_pending.js — approve/reject pending merges

When to read references

• Read references/workflow.md when setting up or extending the process
• Read references/schema-example.json when creating a new master file
• Read references/pending-review-policy.md when conflicts appear
• Read references/outbound-routing-patterns.md when implementing outbound delivery or cross-agent routing
• Read references/examples.md when you want concrete merge/routing examples

Notes

• Do not hardcode a specific agent like main or infoIntelOfficer into the design.
• Model routing as: global subject resolution → app-context identity selection → provider-specific outbound target.
• Keep the skill reusable across future agents and Feishu accounts.
