Feishu Card Skill

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

Prerequisites

• Install feishu-common first.
• This skill depends on ../feishu-common/index.js for token and API auth.

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.

4. Persona Messaging

Send stylized messages from different AI personas. Adds themed headers, colors, and formatting automatically.

node skills/feishu-card/send_persona.js --target "ou_..." --persona "d-guide" --text "Critical error detected."

Supported Personas

• d-guide: Red warning header, bold/code prefix. Snarky suffix.
• green-tea: Carmine header, soft/cutesy style.
• mad-dog: Grey header, raw runtime error style.
• default: Standard blue header.

Usage

• -p, --persona <type>: Select persona (d-guide, green-tea, mad-dog).
• -x, --text <string>: Message content.
• -f, --text-file <path>: Message content from file (supports markdown).
