Plakar Restore Workflows

This skill covers restore operations only. Triggering snapshots is handled automatically by the openclaw-plugin-plakar plugin — you do not need to run plakar backup manually.

When to offer restore

Offer to restore from a Plakar snapshot when the user says anything like:

• "undo that", "roll back", "revert to before", "restore my files"
• "something went wrong, can we go back"
• "the last tool call broke things"

Prerequisites

• plakar must be in $PATH
• The store path is available in plugin config as plakar.store
• Always pass -no-agent to avoid requiring a running plakar agent daemon

CLI syntax (v1.0.6+)

All commands use the form:

plakar -no-agent at <store> <command> [options]

List all snapshots

plakar -no-agent at <store> ls

Output: snapshot ID, timestamp, size, path. Present the list to the user and ask which snapshot to restore from.

Inspect a snapshot's contents

plakar -no-agent at <store> ls <snapshotID>
plakar -no-agent at <store> ls -recursive <snapshotID>:/path

Use this to confirm the snapshot contains the expected state before restoring.

Diff two snapshots

plakar -no-agent at <store> diff <snapshotID1> <snapshotID2>
plakar -no-agent at <store> diff -highlight <snapshotID1>:/file <snapshotID2>:/file

Use this to show the user what changed between two points in time.

Restore a snapshot

Restore all files to the original paths:

plakar -no-agent at <store> restore <snapshotID>

Restore to a specific directory:

plakar -no-agent at <store> restore -to /tmp/restore-here <snapshotID>

Restore a specific path within a snapshot:

plakar -no-agent at <store> restore -to /tmp/restore-here <snapshotID>:/path/to/file

Always confirm with the user before running a restore — it overwrites live files.

Example agent interaction

User: "The last edit broke my config file, can you undo it?"

1. Run plakar -no-agent at <store> ls and show the most recent snapshots
2. Ask: "Should I restore from snapshot <id> taken at <timestamp>?"
3. On confirmation: plakar -no-agent at <store> restore -to <original-path> <id>
4. Confirm the restore completed and invite the user to verify the file
