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.

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.
