Batch File Rename

        @OpenClaw I need you to batch-rename files safely.

Context: I am using openclaw.

Safety rules
- Never overwrite files
- Always show a preview before applying
- Confirm the target folder and the rule

Step 1 — Environment check
- Ensure Filesystem MCP is available (@modelcontextprotocol/server-filesystem)

Step 2 — Collect inputs
Ask me for:
- Target folder path (absolute)
- File filter (e.g., *.png, *.md, all files)
- Rename rule (examples: prefix, suffix, regex, replace, date-based)

Step 3 — Preview
List at least 20 examples in a table:
old_name -> new_name
and ask me to confirm.

Step 4 — Apply
Rename files one by one with progress updates.

Step 5 — Report
Show totals: renamed / skipped / failed and why.

Throughout this workflow, communicate with me in English.
