List the claude.ai / Claude Cowork projects on this account, each tagged with the organization that owns it. Use this to find a project uuid.

Read one project: its name, description, and instructions. Only this tool returns the instructions — list_projects does not carry them.

Create a project. organization_id is needed only when the account belongs to several organizations, and the error will name them if so. A private project is visible to you alone; a normal one is visible to the whole organization.

Change a project's name, description, or instructions. Only the fields you pass are touched; the rest keep their current values. Pass an empty string to clear one.

Delete a project and every document in it. There is no server-side undo, so confirm_name must be set to the project's exact current name. Every document is copied to the local backup directory first; if that fails, nothing is deleted.

List the documents in a project. duplicate_file_names flags names held by more than one document, which happens when a save is interrupted; the next write_document with overwrite=true cleans them up.

Read one document, by file name or uuid. If several documents share the name, the newest is returned and warning names the others.

Create a document, or replace one with overwrite=true. The previous content is backed up locally before any replacement. Pass expected_uuid (from read_document) to refuse the write if a teammate has saved since you read it.

Rename a document, by uuid or by an unambiguous file name. The content is re-created under the new name before the original is deleted, with local backups first, so nothing is lost midway. A new name already in use is refused unless overwrite=true, which replaces its holder (backed up first).

Delete a document, by uuid or by an unambiguous file name. The content is backed up locally first. A name shared by several documents is refused: pass the uuid to say which one.

Copy the project's documents into a local folder. Local files that differ are kept, not overwritten, unless overwrite_local=true.

Upload a local folder's files into the project. Unchanged files are skipped, differing ones need overwrite=true, and remote documents missing locally are never deleted. Use dry_run=true to preview.
