QuotLy Style Sticker

How To Call (Agent)

1. Build payload with required selected_messages.
2. When available, include event metadata for dedupe:
   • context.event.channel (example: telegram)
   • context.event.update_id (preferred)
   • fallback keys: event_id, delivery_id, id
3. Run:
   • python3 scripts/openclaw_quote_autoreply.py --input <json-file-or->
4. Use tool-emitted MEDIA: for delivery.
5. Final assistant text must be empty.

Input

• Required: selected_messages (array, must not be empty)
• Optional: context.event for dedupe accuracy
  • channel (string)
  • update_id (string or number, preferred)
  • event_id / delivery_id / id (fallback keys)
• Each item structure:

  {
    "message": {
      "message_id": 2002,
      "text": "Forwarded message content",
      "forward_from": {
        "type": "hidden_user",  // optional, indicates hidden user
        "id": 123456789,        // optional, user id
        "first_name": "张",     // required, first name or nickname
        "last_name": "三",      // optional, last name
        "avatar_url": "",       // optional, avatar url or base64 data (from user profile or platform API)
        "status_url": ""        // optional, status url or base64 data (from user profile or platform API)
      }
    },
    // Optional: override message fields
    "overwrite_message": {
      "text": "哈哈哈哈哈",
      "forward_from": {
        "avatar_url": "",       // from user profile or platform API
        "status_url": ""        // from user profile or platform API
      },
      "entities": [  // optional, text formatting entities
        {"type": "bold", "offset": 0, "length": 4},
        {"type": "italic", "offset": 5, "length": 4}
      ]
    }
  }
  

• Optional canvas: width, height, scale, max_width, border_radius, picture_radius, background_color

Entities (Text Formatting)

The skill supports Telegram-style message entities for text formatting:

[
  {"type": "bold", "offset": 0, "length": 5},
  {"type": "italic", "offset": 6, "length": 6},
  {"type": "url", "offset": 13, "length": 15, "url": "https://example.com"}
]

Supported types: mention, hashtag, cashtag, bot_command, url, email, phone_number, bold, italic, underline, strikethrough, spoiler, code, pre, text_link, text_mention, custom_emoji

Entity fields:

• type (required) - entity type
• offset (required) - UTF-8 offset in text
• length (required) - UTF-8 length
• url (optional) - for text_link type
• user (optional) - for text_mention type
• language (optional) - for pre type
• custom_emoji_id (optional) - for custom_emoji type

Field Mapping

• Quote text:
  • overwrite_message.text > message.text
• Name/avatar:
  • overwrite_message.forward_from > message.forward_from
• Text formatting (entities):
  • overwrite_message.entities > message.entities > message.caption_entities

Output

• stdout includes:
  • Quote sticker generated.
  • MEDIA:<absolute-path-to-webp>
• For duplicate retries detected within dedupe window, generation is skipped and no MEDIA: line is emitted.

Environment Variables

• QUOTLY_API_URL - QuotLy API endpoint (default: https://bot.lyo.su/quote/generate).
• QUOTLY_API_ALLOW_HOSTS - Comma-separated list of allowed API hosts (e.g., bot.lyo.su). When set, the skill will only contact hosts in this list.
• QUOTLY_AUDIT_LOG - Set to 1, true, or yes to enable audit logging to stderr.
• QUOTLY_DEDUP_WINDOW_SECONDS - Suppress duplicate requests for the same event/payload within this window (default: 180). Set to 0 to disable.

Dedupe Key (How _build_dedupe_key reads input)

_build_dedupe_key(input_payload) resolves keys in this order:

1. context.event.update_id (or event_id / delivery_id / id)
2. event.update_id (or event_id / delivery_id / id) when context.event is missing
3. context.event.update.update_id (nested update object)
4. Fallback: stable hash of selected_messages

Recommended wrapper payload:

{
  "context": {
    "event": {
      "channel": "telegram",
      "update_id": 123456789
    }
  },
  "selected_messages": [
    {
      "message": {
        "message_id": 2002,
        "text": "Forwarded message content"
      }
    }
  ]
}

Security Notes

• This skill sends message content to an external API to generate stickers.
• SSRF Protection: Multiple layers of protection are implemented:
  • Hostname validation blocks internal/private IPs, localhost, and metadata endpoints
  • DNS rebinding protection: resolves hostnames and validates resolved IPs
  • Path traversal prevention: blocks .. and suspicious path patterns
  • URL credentials stripping: removes username/password from URLs
• Request Limits: Maximum payload size 1MB, maximum response size 10MB
• Audit Logging: Enable with QUOTLY_AUDIT_LOG=1 to log API requests and responses for security monitoring
• In sensitive environments, always set QUOTLY_API_ALLOW_HOSTS to restrict which hosts the skill can contact.
• Avatar and status URLs from user input are passed to the rendering service; ensure input comes from trusted sources.

Reply Rule

• Do not output any final text.
