Feishu Card

Feishu Card Skill

Send rich interactive cards to Feishu (Lark) users or groups. Supports Markdown (code blocks, tables), titles, color headers, and buttons.

Usage

1. Simple Text (No special characters)

node skills/feishu-card/send.js --target "ou_..." --text "Hello World"

2. Complex/Markdown Text (RECOMMENDED)

⚠️ CRITICAL: To prevent shell escaping issues (e.g., swallowed backticks), ALWAYS write content to a file first.

1. Write content to a temp file:

# (Use 'write' tool)
write temp/msg.md "Here is some code:\n\`\`\`js\nconsole.log('hi');\n\`\`\`"

2. Send using --text-file:

node skills/feishu-card/send.js --target "ou_..." --text-file "temp/msg.md"

3. Safe Send (Automated Temp File)

Use this wrapper to safely send raw text without manually creating a file. It handles file creation and cleanup automatically.

node skills/feishu-card/send_safe.js --target "ou_..." --text "Raw content with \`backticks\` and *markdown*" --title "Safe Message"

Options

• -t, --target <id>: User Open ID (ou_...) or Group Chat ID (oc_...).
• -x, --text <string>: Simple text content.
• -f, --text-file <path>: Path to text file (Markdown supported). Use this for code/logs.
• --title <string>: Card header title.
• --color <string>: Header color (blue/red/orange/green/purple/grey). Default: blue.
• --button-text <string>: Text for a bottom action button.
• --button-url <url>: URL for the button.
• --image-path <path>: Path to a local image to upload and embed.

Troubleshooting

• Missing Text: Did you use backticks in --text? The shell likely ate them. Use --text-file instead.
