Send PDF to Slack

Converts a markdown file to PDF using weasyprint (Python) and uploads it to a Slack channel via the /api/slack/upload-file endpoint.

Prerequisites

• python3 must be installed (comes with macOS, or brew install python3)
• On first run, a virtual environment is created at ~/.crewly/venv/pdf-tools/ with weasyprint and markdown packages installed automatically

Usage

bash config/skills/agent/send-pdf-to-slack/execute.sh --channel C0123ABC --file /path/to/document.md --title "Weekly Report"

Parameters

Parameter	Required	Description
--channel, -c	Yes	Slack channel ID to upload the PDF to
--file, -f	Yes	Path to the markdown file to convert
--title, -T	No	Title for the uploaded PDF (defaults to filename)
--text, -t	No	Initial comment to include with the upload
--thread, -r	No	Slack thread timestamp for threaded upload

Examples

# Basic upload
bash execute.sh --channel C0123ABC --file report.md

# Upload with title and comment
bash execute.sh --channel C0123ABC --file report.md --title "Q4 Report" --text "Here is the quarterly report"

# Upload in a thread
bash execute.sh --channel C0123ABC --file notes.md --thread 1707123456.789000
