Find Package (找快递)

Help users find their packages on delivery station shelves. The user provides a pickup code and shelf photos, and you identify which package matches — marking it with a red bounding box and sending the annotated image back.

Workflow

Step 1: Get the pickup code (取件码)

Ask the user for their pickup code. Speak in Chinese — this is a Chinese-locale feature.

The user may respond with:

• Plain text: e.g. "5-2-1234" or "五号架 二层 1234"
• A screenshot: SMS notification or 菜鸟裹裹/丰巢/中通 app screenshot containing the code

Pickup code format: Typically X-Y-ZZZZ where X = shelf/section number, Y = row/layer, ZZZZ = code digits. Variations exist — some use Chinese characters, some just numbers. Extract whatever looks like a pickup reference code.

If the user sends an image, use your vision capabilities to read the pickup code from it. Look for patterns like:

• 取件码：5-2-1234
• 货架号：5 取件码：1234
• 格口：5-2-1234

Confirm the extracted code with the user before proceeding: "我识别到的取件码是 5-2-1234，对吗？"

Step 2: Get shelf photos (货架照片)

Once you have the confirmed pickup code, ask the user to take photos of the package shelves. Tell them:

"请拍一下货架的照片发给我，可以一次发多张～"

The user may send:

• A single photo of one shelf section
• Multiple photos covering different shelf sections

Step 3: Recognize and match

For each shelf photo the user sends:

1. Read the image with your vision capabilities — identify all visible package labels, tracking numbers, and pickup codes on the shelf
2. Match the detected codes against the user's pickup code
3. If a match is found:
• Note the bounding box coordinates (in pixels) of the matching package label
• Use the annotation script to draw a prominent red bounding box:

python3 {baseDir}/scripts/annotate.py \
  --input /path/to/shelf_photo.jpg \
  --output /tmp/find-package-result.jpg \
  --box "x1,y1,x2,y2" \
  --label "取件码: 5-2-1234"

• Send the annotated image back to the user via the message tool with media: "file:///tmp/find-package-result.jpg"

1. If no match is found in this photo, tell the user and ask if there are more shelves to check

Step 4: Report results

When a package is found:

• Send the annotated photo with the red bounding box
• Say something like: "找到了！你的快递在这里，取件码 5-2-1234"

If the user has multiple pickup codes (they mentioned several or you detected multiple in the screenshot):

• Track which ones have been found and which are still missing
• After each shelf photo, report: "已找到 2/3 个快递，还有 1 个没找到（取件码：7-3-5678）"

When all packages are found:

• "全部找到了！祝取件顺利～"

When no match found after all photos:

• "在这些照片里没有找到你的快递，要不要再拍几张其他货架的照片？"

Important Notes

• Always communicate in Chinese — this feature is for Chinese delivery stations (驿站/快递柜)
• Be patient — users may be unfamiliar with taking clear shelf photos. If OCR is unclear, ask them to retake with better lighting or angle
• The pickup code format varies by delivery company. Common formats:
• X-Y-ZZZZ (e.g., 5-2-1234)
• Just numbers on a label
• QR codes (if you can't read QR, tell the user to provide the text code instead)
• When drawing bounding boxes, make them visually prominent: thick red lines, with the pickup code label above the box
• If the shelf photo is blurry or codes are unreadable, ask for a clearer photo rather than guessing

Sending Messages

Use the message tool with channel: "telegram":

{
  "action": "send",
  "channel": "telegram",
  "message": "请发一下你的取件码～可以直接打字，也可以截图给我"
}

Send with annotated image:

{
  "action": "send",
  "channel": "telegram",
  "message": "找到了！你的快递在红框标记的位置",
  "media": "file:///tmp/find-package-result.jpg"
}
