Feishu Media Delivery

Use this skill as the last-mile delivery layer for multimodal agents.

It does not generate content.
It only makes sure already-generated files are sent to Feishu with the correct protocol.

What this skill is for

Use this skill when you already have a generated result and need to deliver it to a Feishu user/chat.

Typical cases:

• - A generated jpg/png must be sent as a real Feishu image message
• A generated mp4 must be sent as a real Feishu media message
• A multimodal agent finished generation and now needs reliable delivery
• You want to avoid protocol mistakes like sending jpg/mp4 as the wrong message type

Hard rules

Images

For images, do not send the local file as plain text or guess a generic attachment format.

Correct flow:

1. 1. Upload image to Feishu IM resource API
2. Get INLINECODE0
3. Send message with INLINECODE1

Use:

• - INLINECODE2

Videos

For mp4 videos, do not send them as file messages.

Correct flow:

1. 1. Upload mp4 to Feishu IM file API
2. Get INLINECODE4
3. Send message with INLINECODE5

Use:

• - INLINECODE6

Required environment

The scripts expect:

• - INLINECODE7
• INLINECODE8 or default secret file at INLINECODE9

Default secret path:

• - INLINECODE10

Receive ID assumptions

The bundled scripts default to receive_id_type=open_id.

Use them directly when the target is a Feishu user open_id like:

• - INLINECODE13

If you need group delivery later, extend the script to accept chat_id and switch receive_id_type.

Commands

Send image to a Feishu user

CODEBLOCK0

Example:

CODEBLOCK1

Send mp4 video to a Feishu user

CODEBLOCK2

Arguments:

• - arg1: target open_id
• arg2: local mp4 path
• arg3: file type, usually INLINECODE16
• arg4: duration in milliseconds, optional but recommended

Example:

CODEBLOCK3

Output expectations

A successful send should return Feishu success payloads such as:

• - INLINECODE17
• INLINECODE18

Do not assume transport success only from local script execution.
Check the returned Feishu response.

Fallback policy

Image fallback

If real Feishu image sending fails, report that image delivery failed. Do not silently pretend the image was delivered.

Video fallback

If Feishu media sending fails, fallback to sending a direct link if one exists. State clearly that this is a fallback.

Recommended agent usage

For a multimodal content agent, use this skill after generation:

• - image result -> INLINECODE19
• mp4 result -> INLINECODE20

This keeps protocol details out of the model prompt and reduces failure risk for weaker models.
