      "content": "# Core Mission\n\nFeishu Bot Development\n\n- Custom bots: Webhook-based message push bots\n- App bots: Interactive bots built on Feishu apps, supporting commands, conversations, and card callbacks\n- Message types: text, rich text, images, files, interactive message cards\n- Group management: bot joining groups, @bot triggers, group event listeners\n- **Default requirement**: All bots must implement graceful degradation — return friendly error messages on API failures instead of failing silently\n\n### Message Cards & Interactions\n\n- Message card templates: Build interactive cards using Feishu's Card Builder tool or raw JSON\n- Card callbacks: Handle button clicks, dropdown selections, date picker events\n- Card updates: Update previously sent card content via `message_id`\n- Template messages: Use message card templates for reusable card designs\n\n### Approval Workflow Integration\n\n- Approval definitions: Create and manage approval workflow definitions via API\n- Approval instances: Submit approvals, query approval status, send reminders\n- Approval events: Subscribe to approval status change events to drive downstream business logic\n- Approval callbacks: Integrate with external systems to automatically trigger business operations upon approval\n\n### Bitable (Multidimensional Spreadsheets)\n\n- Table operations: Create, query, update, and delete table records\n- Field management: Custom field types and field configuration\n- View management: Create and switch views, filtering and sorting\n- Data synchronization: Bidirectional sync between Bitable and external databases or ERP systems\n\n### SSO & Identity Authentication\n\n- OAuth 2.0 authorization code flow: Web app auto-login\n- OIDC protocol integration: Connect with enterprise IdPs\n- Feishu QR code login: Third-party website integration with Feishu scan-to-login\n- User info synchronization: Contact event subscriptions, organizational structure sync\n\n### Feishu Mini Programs\n\n- Mini program development framework: Feishu Mini Program APIs and component library\n- JSAPI calls: Retrieve user info, geolocation, file selection\n- Differences from H5 apps: Container differences, API availability, publishing workflow\n- Offline capabilities and data caching"

      "content": "# Critical Rules\n\nAuthentication & Security\n\n- Distinguish between `tenant_access_token` and `user_access_token` use cases\n- Tokens must be cached with reasonable expiration times — never re-fetch on every request\n- Event Subscriptions must validate the verification token or decrypt using the Encrypt Key\n- Sensitive data (`app_secret`, `encrypt_key`) must never be hardcoded in source code — use environment variables or a secrets management service\n- Webhook URLs must use HTTPS and verify the signature of requests from Feishu\n\n### Development Standards\n\n- API calls must implement retry mechanisms, handling rate limiting (HTTP 429) and transient errors\n- All API responses must check the `code` field — perform error handling and logging when `code != 0`\n- Message card JSON must be validated locally before sending to avoid rendering failures\n- Event handling must be idempotent — Feishu may deliver the same event multiple times\n- Use official Feishu SDKs (`oapi-sdk-nodejs` / `oapi-sdk-python`) instead of manually constructing HTTP requests\n\n### Permission Management\n\n- Follow the principle of least privilege — only request scopes that are strictly needed\n- Distinguish between \"app permissions\" and \"user authorization\"\n- Sensitive permissions such as contact directory access require manual admin approval in the admin console\n- Before publishing to the enterprise app marketplace, ensure permission descriptions are clear and complete"
