Fix a bug in an add-on's code until the author ships a fix
The error stops today with a small, documented change, the original file is kept, and you know to recheck it after the add-on's next update.
What it replaces: 1-2 h of a developer's time
What you write to Claude
„the dpdlabels module throws 'Undefined array key' in ProductHooks.php line 212 on php 8.2. show me the code, propose the smallest fix, back it up and apply it. note it so we redo it after the next update”
The problem
Since the server update a shipping add-on fills the error log with warnings on every product page. The author promises a fix next month.
What Claude does
- Claude reads the error and opens the add-on's file at the right line.
- It proposes the smallest change and shows exactly what will differ.
- It warns that the add-on's next update will replace the file and erase the fix.
- After your yes it saves the change with a backup and checks the error log again.
What you get
The warnings stop, the change is recorded with a copy of the original file, and it's on your list to recheck after the next update.
You stay in control
You see every change before it is saved and nothing happens without your yes. Work on add-ons uses a separate, extra-protected connection, usually set up by whoever looks after your shop, and add-on files are backed up before they change.

- Tools
- ps_get_logs, ps_module_file, ps_list_file_backups, ps_restore_file_backup, ps_override_module_template
Step by step
- Confirms file and line with ps_get_logs.
- Reads the file with ps_module_file (action read: module, path, from_line).
- Proposes a minimal patch and calls ps_module_file (action edit, search/replace); the preview shows the diff, PHP syntax is checked before saving and a backup is made.
- Re-checks ps_get_logs; if needed restores with ps_list_file_backups and ps_restore_file_backup.
- Reminds you that module updates overwrite module files; changes of look belong in a theme override (ps_override_module_template).
Safety
Modules (block 4) work only through the service connector (separate token accepted only from allowlisted IP addresses) and are off after installation; the owner gets an e-mail when the block is switched on. Every write shows a preview, runs only after your approval (one-time token) and is logged in the change history. Changes to module files are lost when the module is updated. PHP files are syntax-checked and backed up before saving; there is no tool that runs arbitrary PHP code.
