Thanks @glifocat! Clean skill package — good docs, solid tests, nice intent files. Pushed a small fix for path traversal on the PDF filename before merging.

# Intent: src/channels/whatsapp.ts modifications
|
|
|
|
## What changed
|
|
Added PDF attachment download and path injection. When a WhatsApp message contains a PDF document, it is downloaded to the group's attachments/ directory and the message content is replaced with the file path and a usage hint. Also uses `normalizeMessageContent()` from Baileys to unwrap container types before reading fields.
|
|
|
|
## Key sections
|
|
|
|
### Imports (top of file)
|
|
- Added: `downloadMediaMessage` from `@whiskeysockets/baileys`
|
|
- Added: `normalizeMessageContent` from `@whiskeysockets/baileys`
|
|
- Added: `GROUPS_DIR` from `../config.js`
|
|
|
|
### messages.upsert handler (inside connectInternal)
|
|
- Added: `normalizeMessageContent(msg.message)` call to unwrap container types
|
|
- Changed: `let content` to allow reassignment for PDF messages
|
|
- Added: Check for `normalized.documentMessage?.mimetype === 'application/pdf'`
|
|
- Added: Download PDF via `downloadMediaMessage`, save to `groups/{folder}/attachments/`
|
|
- Added: Replace content with `[PDF: attachments/{filename} ({size}KB)]` and usage hint
|
|
- Note: PDF check is placed BEFORE the `if (!content) continue;` guard so PDF-only messages are not skipped
|
|
|
|
## Invariants (must-keep)
|
|
- All existing message handling (conversation, extendedTextMessage, imageMessage, videoMessage)
|

|
|
- Group metadata sync unchanged
|
