Feishu File Send / 飞书文件发送
Use this skill whenever you need to send a file to a Feishu user, or when a Feishu user reports they did not receive an attachment.
当需要向飞书用户发送文件，或用户反馈未收到附件时，使用此 Skill。
Core Rule / 核心规则
For Feishu, do NOT combine text and attachment in one outbound message when reliability matters.
飞书场景下，不要将文字说明和附件合并到同一条消息中发送。
Always use this sequence / 始终按此顺序操作：
- Prepare the file in an allowed local path / 将文件保存到允许的目录
- Send a short text message first, if any explanation is needed / 先发一条简短文字说明
- Send the attachment as a separate outbound message / 再单独发送附件
When to Use / 使用场景
Use it when the user asks you to / 当用户要求你：
- send a file / 发送文件
- return an edited document / 返回编辑后的文档
- deliver a generated Word, Excel, PDF, PPT, TXT, image, or similar attachment / 发送生成的文档、表格、PDF、图片等附件
- test Feishu attachment sending / 测试飞书附件发送功能
- debug missing Feishu attachments / 排查飞书附件丢失问题
- diagnose file delivery failures in Feishu / 诊断飞书文件发送失败
This skill is especially important in Feishu DMs, but the same pattern is also safer in Feishu groups.
此 Skill 在飞书私聊中尤为重要，但在飞书群聊中也建议使用相同模式。
Required Workflow / 标准流程
1. Check the file path / 检查文件路径
Before sending, ensure the file lives under an allowed mediaLocalRoots directory.
发送前，确保文件位于 mediaLocalRoots 配置的允许目录中。
Known-good path in most setups / 通常可用的路径：
~/.openclaw/workspace/(the default workspace directory / 默认工作区目录)
If a generated file is under /tmp/ or another temporary path, move or copy it into an allowed directory before sending, unless you already know that path is whitelisted in mediaLocalRoots.
如果文件在 /tmp/ 或其他临时目录，请先复制到允许目录再发送，除非你确认该路径已在白名单中。
2. Send text separately / 先发送文字
If you need to say something like "here is the file" or explain what changed, send that as a plain text message first.
如果需要说明"这是文件"或解释修改内容，先发送纯文字消息。
Keep it short / 保持简短。
3. Send the attachment separately / 再发送附件
Send the file in its own message using the message tool with media set to the local file path.
使用 message 工具单独发送文件，media 参数设为本地文件路径。
Do NOT attach explanatory text to the same outbound file message.
不要在同一条附件消息中包含说明文字。
What to Avoid / 禁止操作
Do NOT / 不要：
- combine text and file in one Feishu outbound message when attachment visibility matters / 在需要确保附件可见性时，将文字和文件合并到一条消息
- assume
/tmp/is safe to send from / 默认/tmp/目录可以发送文件 - use
MEDIA:inline attachment rendering for Feishu when you need reliable file delivery, if you can directly use themessagetool instead / 在需要可靠文件发送时，避免使用MEDIA:内联渲染，直接使用 message 工具
Delivery Pattern / 发送模式
Preferred pattern / 推荐模式：
message.sendwith text only / 仅发送文字message.sendwith media only / 仅发送附件- After tool success, do not duplicate the same content again in chat / 工具成功后，不要在聊天中重复相同内容
If you use message to deliver the user-visible reply, answer with NO_REPLY.
Failure Diagnosis / 故障排查
If the recipient says they did not receive the file / 如果用户说没收到文件：
- Confirm whether plain text messages are arriving / 确认纯文字消息能否正常收到
- Confirm whether the file was sent as a standalone attachment message / 确认文件是否作为独立附件消息发送
- Confirm the file path is inside
mediaLocalRoots/ 确认文件路径在mediaLocalRoots白名单内 - Retry by copying the file into
~/.openclaw/workspace/(or another allowed directory) and re-sending / 复制到~/.openclaw/workspace/或其他允许目录后重试 - If needed, consult

Known Validated File Types / 已验证的文件类型
Validated in Feishu DM on 2026-04-16 when sent separately / 2026-04-16 在飞书私聊中验证通过（分开发送）：
- txt — 纯文本
- docx — Word 文档
- xlsx — Excel 表格
- pdf — PDF 文档
You may still send other file types, but if reliability matters and they fail, debug using the same path and separation rules.
其他文件类型也可发送，如果失败请按相同规则排查。
Config Tips / 配置建议
If dynamic files are commonly generated under /tmp/, consider adding /tmp to Feishu mediaLocalRoots in ~/.openclaw/openclaw.json and restart gateway.
如果经常生成临时文件，可在配置中将 /tmp 加入飞书渠道的 mediaLocalRoots 白名单，然后重启 gateway。
