LINE Rich Messages

This skill transforms the agent from a text-only bot into a professional LINE assistant with native UI capabilities.

Core Principle: Rich-UI 優先 (Low-Friction)

Typing on mobile is slow and error-prone. Always prioritize Rich UI elements to minimize the user's need to reply with text.

Quick Navigation

Detailed guides for each feature:

1. decision-matrix.md: Choose the best UI element for your scenario.
2. directives.md: Syntax for interactive cards and bubbles.
3. flex-templates.md: Raw JSON Templates for 100% reliable UI creation.
4. markdown-to-flex.md: Auto-美化 tables and code blocks.

Best Practices

• No file delivery: For security, this skill intentionally does not include any workflow for uploading/sharing files (e.g., Google Drive). If you need file delivery, implement it in a separate, tightly-scoped skill with explicit allowlists and safeguards.
• Guided Choices: If you ask a question with 2-4 fixed answers, always include [[quick_replies: ...]].
• Structured Data: Use Markdown tables for any multi-point information (e.g., flight times, order items).
• Destructive Actions: Use [[confirm: ...]] for actions like "Delete Memory" or "Cancel Project".
• UX Limitation (Crucial): Text within Flex Messages (including Markdown tables and auto-converted replies) cannot be selected or copied by the user.
  • Rule: If the data is meant to be copied (e.g., SSH keys, IDs, URLs), always send it as plain text without Markdown formatting or directives that trigger Flex conversion.

Security / Scope (Important)

• This skill is documentation + templates for building a better LINE UX (Flex, buttons, quick replies).
• It does not ship credentials and does not automatically make external API calls.
• Anything that touches the network or third-party services must be explicitly requested by the user and only after the runtime is correctly configured.

Credentials / Setup Clarification

• LINE: Sending messages is handled by your OpenClaw LINE channel/plugin setup. This skill does not require you to declare or embed LINE_CHANNEL_ACCESS_TOKEN / LINE_CHANNEL_SECRET.
• File delivery: Intentionally not included (removed for safety). Do not upload/share local files from an agent runtime.

🏆 終極解決方案：手工 Raw Flex (The Golden Path)

若系統標籤轉換失敗，請使用 手工構建 JSON。這是最穩定且能 100% 呈現自定義 UI 的方式。

穩定發送按鈕的 JSON 模板

將此 JSON 作為純文字發送，若系統支援自動偵測則會轉換；若不支援，請改走 OpenClaw 的 LINE plugin 正規發送路徑（或由管理員在已授權的環境中操作），避免在 skill 內容中引導直接 curl 呼叫外部 API。
