Slack Backup

Back up files uploaded to a Slack channel to the local doc/backup directory. Supports smart matching: multiple files, filename prefix/keyword filter, file type (pdf/video/image), and time range ("just now" = "last 5 minutes"). Trigger when the user says things like "back up the file from Slack", "back up the PDF I just sent to Slack", "save the Slack file locally", etc.

File contents

Slack Backup Skill

Backup directory: ~/.openclaw/doc/backup/

Strict rules (must be followed — violations are treated as critical errors):

Do not use write/edit tools to create or modify any files
Do not create Python scripts, test scripts, or any auxiliary files
Do not generate, guess, or fabricate file contents and write them to disk — even if the filename is known
Only run slack_backup.sh via exec to download real files
Must verify that the script outputs SUCCESS: /path/to/file and that the file exists with size > 0
If the script reports ERROR, inform the user honestly — do not fabricate a success status

Smart Matching: Interpret Intent → Set Variables → Call Script

The agent interprets the user's natural language, determines intent, sets the corresponding environment variables, then calls the script.

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

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

Invocation

# Default: back up latest file
<SKILL_DIR>/slack_backup.sh

# Back up the latest 2 files
LIMIT=2 <SKILL_DIR>/slack_backup.sh

# Back up files whose name starts with "report"
NAME_PREFIX=report <SKILL_DIR>/slack_backup.sh

# Back up PDFs uploaded in the last 5 minutes
MINUTES=5 FILE_TYPE=pdf <SKILL_DIR>/slack_backup.sh

# Back up up to 3 files from the last 10 minutes
LIMIT=3 MINUTES=10 <SKILL_DIR>/slack_backup.sh

Script prints SUCCESS: /path/to/file for each file on success.

Important: The script downloads real files from the Slack API. The downloaded file size should match the original. If a backup file is unexpectedly small (e.g. a few KB), something went wrong — report the error to the user honestly.
