Skills Backup Keeper
Your skills folder can be wiped without warning. This skill makes sure that costs you five minutes, not five weeks.
What it produces
- A dated, never-overwritten copy of your whole skills folder at /Documents/Cowork/skills-backup/YYYY-MM-DD/, with a backup-manifest.md listing exactly what was copied.
- An append-only session-journal.md (goal, files touched, decisions, next steps) stored in skills-backup/, outside the skills folder, so a wipe cannot take it too. A new conversation reads it and resumes where the last one stopped.
- A guided, approval-gated restore that copies a chosen backup back into /Documents/Cowork/skills/ and verifies the result against the manifest.
What to say to it
- “Back up my skills folder before I edit anything”
- “Update the session journal: we finished the budget review skill, next step is testing”
- “New conversation. Where did we leave off?”
- “My skills folder is empty again. Restore from the latest backup.”
How to install it
- 1Download skills-backup-keeper.zip.
- 2In Cowork, open Customize.
- 3Select the Skills tab.
- 4Select the arrow next to Add, then Upload skill, and choose the file you downloaded.
- 5Start a new conversation and use one of the phrases above. Skills are only picked up when a conversation starts.
Cowork has to be switched on for you by an admin, and it is off by default. Custom skills are not supported on a phone or tablet, so use a laptop or desktop.
Cowork checks the file when you upload it and tells you if something is wrong, so you will know either way.
