Send Feishu Message

The send logic is in scripts/feishu-send (bundled with this skill).

Step 0 — Locate and prepare the script

# Find the script relative to where this skill is installed
SKILL_DIR="$(find ~/.claude/plugins -name 'send-feishu' -path '*/skills/*' -type d 2>/dev/null | head -1)"
FEISHU_SEND="${SKILL_DIR}/scripts/feishu-send"
chmod +x "$FEISHU_SEND" 2>/dev/null
echo "script: $FEISHU_SEND"

If the script is not found (e.g., skill loaded from local dev path), use:

FEISHU_SEND="$(dirname "$0")/scripts/feishu-send"

Choose Format

Situation	Format
Simple one-liner, status update	`text`
Has title + body, structured data, report	`card`
Image file / screenshot / chart	`image`
.md / .html / .pdf / .doc / large content	`file`
User says "发给我" / "私发" / names a person	use `FEISHU_USER_OPEN_ID`

Card color: green=success, orange=warning, red=error, blue=info (default), purple=highlight.

Send

# Text
"$FEISHU_SEND" text "消息内容"

# Card
"$FEISHU_SEND" card "标题" "正文（支持 lark_md：**粗体** *斜体* \n换行）" --color blue

# Image
"$FEISHU_SEND" image /path/to/image.png

# File
"$FEISHU_SEND" file /path/to/report.md

# Dry-run (verify vars without sending)
"$FEISHU_SEND" --dry-run text "test"

The script handles: variable resolution (including CTI_FEISHU_* aliases) → routing → token acquisition → upload → send → error reporting.

Environment Variables

Variable	Purpose
`FEISHU_WEBHOOK`	Group webhook URL
`FEISHU_APP_ID` + `FEISHU_APP_SECRET`	Required for image/file upload and API sends
`FEISHU_CHAT_ID`	Group chat ID (`oc_xxx`)
`FEISHU_USER_OPEN_ID`	Individual (`ou_xxx`)
`FEISHU_WEBHOOK_SECRET`	Only if webhook signature is enabled

If vars are unset after resolution, tell user which ones to configure.
