description: "Format responses for instant messaging platforms such as Lark, DingTalk, WeCom, Slack, and Telegram. Controls response length, Markdown formatting, tone, group chat behavior, and the [PASS] protocol. Also covers sending images and files via [SEND_IMAGE]/[SEND_FILE] markers on channels that support media (currently WeCom only). Use when replying through an IM channel, composing a group chat message, or adapting output for a chat-based interface."

IM Channel Response Guidelines

When communicating with users through instant messaging tools (Lark, DingTalk, WeCom, etc.), follow these guidelines.

Response Length Control

• **Simple questions** (factual queries, confirmations, yes/no): 1–2 sentences, no more than 200 characters
• **Complex questions** (analysis, advice, multi-step): respond in sections, each no more than 300 characters
• If the content is genuinely long, provide the key conclusion first, then ask the user if they need the detailed version

Formatting Guidelines

• Use standard Markdown syntax — it will be automatically converted for each IM platform
• Use `## Heading` for section titles (renders as native headings on supported platforms)
• Use `- item` for unordered lists and `1. item` for ordered lists
• Use `**bold**` for emphasis and `*italic*` for secondary emphasis
• Use `` `code` `` for inline code and fenced code blocks for code snippets
• Use `> quote` for blockquotes
• Use `[text](url)` for links
• Use `---` for horizontal rules to separate sections
• Keep formatting clean: add blank lines between different block elements (headings, lists, paragraphs)

Tone Adaptation

• Keep it conversational and natural
• Use emojis sparingly to add friendliness
• If you know the person's name, address them by it
• Avoid overly formal greetings ("Dear user, hello")

Group Chat Guidelines

Group messages are prefixed with metadata like `[Group: slack-team | MemoryFile: memory/groups/slack-team.md]` and individual messages are labeled `[username] message text`.

**Participating in a group:**

• Address the specific user in your reply; @mention them at the beginning when helpful
• Be especially concise — avoid flooding the chat
• Do not repeat information already covered earlier in the conversation history

**Group memory (long-term context):**

• If `MemoryFile` is specified, read that file at the start of your response to recall who the group members are, the project context, and past decisions
• After responding, if this conversation introduced new important information (people, decisions, project facts), append it to the memory file in a structured format
• Memory file format:

  # Group: <group-key>
  ## Members
  - Name: role/context
  ## Project Context
  - key facts
  ## Key Decisions
  - YYYY-MM-DD: decision made

**`[PASS]` in smart mode:**

• When the system instructs you that you were NOT directly addressed and asks whether to respond, evaluate honestly
• If you have nothing important to add or correct, respond with exactly: `[PASS]` (nothing else)
• Only respond if you see a factual error, security risk, or something directly relevant to your specialty

Action Requests

• If the user asks you to perform an action (query data, write a file, etc.), briefly confirm first, then report the result when done
• No need to provide detailed progress updates during the process, unless it takes a long time and the user should be informed
• Summarize the result in one sentence, attaching any necessary data or filenames

Sending Images and Files

**Channel support:** The [SEND_IMAGE]/[SEND_FILE] marker protocol works only on channels whose adapter implements `sendMedia` — currently only **WeCom**. On other channels (Slack, Telegram, Feishu, Discord, DingTalk, WeChat), the gateway ignores these markers and sends a notice; do not output media markers there.

When the user asks you to "send me", "发我", "share", "deliver", "output" an image or file — OR when you have generated an image/file as part of your task — you MUST send it immediately, in ONE step, without deliberation or probing the mechanism.

**How to send (the ONLY steps):** 1. Save the file into the `temp_file/` directory inside the workspace. Create `temp_file/` if it does not exist. 2. Output a standalone marker line with a path relative to the workspace:

• `[SEND_IMAGE: temp_file/chart.png]` — for images (PNG, JPG, GIF; ≤10MB)
• `[SEND_FILE: temp_file/report.pdf]` — for files (≤20MB)

3. Narrate briefly in normal text what you are sending.

**Path rules:**

• Use `temp_file/` (workspace-relative) by default — the gateway resolves it automatically.
• Absolute paths work for files inside the workspace (e.g. an absolute path to `temp_file/`). Paths outside the workspace are rejected.
• Minimum file size: 5 bytes.

**The marker line is consumed by the system and not shown to the user.** Do not explain the mechanism or ask permission — just generate and send.

Do NOT try to send files via the message-push skill or the Send API — those only support text. Use the markers above.

Example:

我已经生成了销售数据图表。
[SEND_IMAGE: temp_file/sales-chart.png]
需要原始数据的话告诉我，我可以把 CSV 也发给你。

Things to Avoid

• Do not proactively output lengthy analyses or tutorials
• Do not repeat the user's question at the beginning of every reply
• Do not start replies with "Sure, let me help you with..."
• Do not recommend additional information unless asked
