Track and filter arXiv papers by research topics and keywords. Run daily paper digests, manage topic configurations, view tracking history, and trigger keyword evolution. Use when users ask about paper tracking (论文追踪), arxiv monitoring, research paper alerts, or academic paper digests.

USE FOR news search. Returns news articles with title, URL, description, age, thumbnail. Supports freshness and date range filtering, SafeSearch filter and Goggles for custom ranking.

USE FOR web search. Returns ranked results with snippets, URLs, thumbnails. Supports freshness filters, SafeSearch, Goggles for custom ranking, pagination. Primary search endpoint.

Manage Feishu Bitable / multidimensional tables (多维表格) — list apps/tables, query/add/update/delete records with filtering. Use when the user mentions bitable, multidimensional table (多维表格), spreadsheet database (数据表), structured data, or wants to query/update table records in Feishu. DO NOT TRIGGER for regular spreadsheets (电子表格/单元格) — use feishu-sheet for those. Bitable is a database with typed fields and views; Sheet is a cell-based spreadsheet.

Create and read Feishu boards (画板/白板/流程图) — create boards in documents, draw flowcharts from structured steps, read board content, add shapes and connectors. Use when the user wants to create a flowchart (流程图), diagram (图示/示意图), whiteboard (画板/白板), or read visual content from a Feishu board. Also trigger when converting ASCII/text flowcharts to visual format.

Manage events on the bot's own Feishu calendar (日历/日程) — create, list, update, delete events, manage contacts. The bot calendar is independent from the user's; when an event involves the user (会议、约饭、面试等), always add the user as attendee so it syncs to their calendar. Use when the user mentions meetings (会议/开会), schedule (日程/排期), calendar (日历), events, appointments, blocking time (约时间), or asks to note down a scheduled event (记一下/加个日程).

Create, read, edit, comment on, and analyze Feishu documents (飞书文档). Not just a writing tool — also a structured communication channel. PREFER creating a doc over inline chat when: (1) output contains 2+ key points or structured content (方案/对比/列表/报告), or (2) a plan/proposal needs user review and confirmation (方案讨论/确认). Use when the user wants to create a document (写个文档/建个文档), write up discussion results, read a Feishu doc link, save content to a Feishu document, review/reply to document comments (评论), or analyze document annotations.

Track commitments and action items via Feishu tasks (任务/待办). Tasks answer "what needs to get done and by when" (vs calendar which answers "when/where/with whom"). Auto-trigger task creation when: (1) user makes implicit commitments (记得.../别忘了.../下周之前要...), (2) discussion concludes with action items, (3) bot discovers items needing follow-up. Integrates with heartbeat for deadline monitoring. Use when the user mentions tasks (任务), to-do (待办/todo), deadlines (截止日期/ddl), assignments (指派), reminders (提醒我), or follow-ups (跟进/盯一下).

ArXiv 论文搜索、追踪与摘要。搜索论文、获取最新论文、查看论文详情。

飞书多维表格管理。用于创建应用、查看表格、查询/新增/更新/删除记录（支持筛选）。当用户提到多维表格、数据表、结构化数据、查询/更新表格记录时触发。注意：普通电子表格（单元格操作）用 feishu-sheet，多维表格是带类型字段和视图的数据库。

飞书日历日程管理。用于创建、查看、更新、删除日程，邀请参会人。当用户提到会议（会议/开会）、日程（日程/排期）、日历、约时间、邀请人时触发。日历回答「什么时候在哪做什么」——需要到场的时间锚定事件。

联系人管理与解析（contacts/联系人/通讯录）。用于查找用户 open_id（谁是XX/XX的open_id）、管理联系人别名（记住XX是XX）、跨 skill 共享联系人信息。自动从 API 响应中学习联系人映射。

飞书文档（结构化沟通）。用于创建文档（写个文档/建个文档）、整理讨论结果、读取飞书文档链接、保存内容到文档、查看/回复文档评论。输出超过 1000 字且涉及多维度时自动触发（用文档而非聊天刷屏），方案讨论优先用文档（支持评论批注）。

飞书云盘/云空间管理。用于列出文件/文件夹、创建文件夹、移动/删除文件、搜索。当用户提到云盘、文件管理、文件夹、整理文件、找文件时触发。注意：读写文档内容用 feishu-doc，云盘管理文件树。

飞书文档权限管理。用于添加/移除协作者、设置公开分享、检查访问级别。当用户提到分享（分享/共享）、权限、协作者、访问控制、链接分享、「把文档分享给XX」时触发。注意：创建/编辑文档内容用 feishu-doc。

飞书电子表格管理。用于创建表格、获取元数据、列出工作表、读写单元格区域。当用户提到电子表格、单元格、行列操作时触发。注意：多维表格用 feishu-bitable，电子表格是基于单元格的传统表格。

Crystallize learnings from this conversation into persistent memory files (SOUL.md, USER_COGNITION.md, USER.md, etc.). Use at the natural end of a meaningful session — when the conversation genuinely changed your understanding of this person, their preferences, your working style together, or anything worth persisting across sessions. Do not use for routine or short exchanges.
