| name | slack-backup |
| description | 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. |
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
<SKILL_DIR>/slack_backup.sh
LIMIT=2 <SKILL_DIR>/slack_backup.sh
NAME_PREFIX=report <SKILL_DIR>/slack_backup.sh
MINUTES=5 FILE_TYPE=pdf <SKILL_DIR>/slack_backup.sh
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.
