Putting Claude to work on real files
- 01What Cowork sees and what it does not see10 min
Cowork only modifies files in the folders you have connected, but it sees more than files: with your authorisation it takes screenshots of your screen, and from Chrome's side panel it sees the displayed page. Close or hide whatever has nothing to do with the task.
- 02Working on a copy, never on the original5 min
Work on a copy, because Claude modifies the file itself, where it sits, and creates no backup behind the scenes. A rewrite does not require the confirmation a deletion does, so a silent error becomes more likely. Duplicate any document that must remain a reference before handing it to Claude.
- 03Skills and plugins, specialisation on demand5 min
A skill is a specialisation Claude loads for a specific domain or a repeated way of doing something, written once. A plugin bundles several skills into a single installable package. Read the description before activating either: it is the only place where its author states what it does.
- 04Connectors, a direct link to a piece of software5 min
A connector is an authenticated link between Claude and an external service, such as a mailbox, a calendar or a file space. Authorising it commits you beyond the current conversation, right up to your scheduled tasks, and on an organisation account an administrator sets the list of connectors offered.
