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
