Slack Print

Print files uploaded to a Slack channel. Supports smart matching: multiple files, filename prefix/keyword filter, file type (pdf/image), and time range ("just now" = "last 5 minutes"). Trigger when the user says things like "print the file from Slack", "print the PDF I just sent to Slack", "print the Slack file", etc.

Strict rules:

Do not use write/edit tools to create or modify any files
Do not create Python scripts, test scripts, or any auxiliary files

Print Files from Slack

Smart Matching: Interpret Intent → Set Variables → Call Script

User says	Environment variables
"Print the latest file" / "Print this file"	(default, no variables needed)
"Print the last two files" / "Print these two files"	`LIMIT=2`
"Print files starting with report"	`NAME_PREFIX=report`
"Print files with contract in the name"	`NAME_CONTAINS=contract`
"Print the PDF I just uploaded" / "Print the PDF from just now"	`MINUTES=5 FILE_TYPE=pdf`
"Print the last three files"	`LIMIT=3 MINUTES=10`

FILE_TYPE values: pdf / image / video / doc / file (default — matches all)

Invocation

# Default: print latest file
PRINTER=MyPrinter <SKILL_DIR>/slack_fetch_and_print.sh

# Print the latest 2 files

# Print PDFs uploaded in the last 5 minutes
