Claude Cowork discovery misses cloud-backed cse_… sessions visible in Claude Desktop

[nhod]

What happened?

A cloud-backed Cowork session is visible, openable, and complete in Claude Desktop, but txcript's cowork harness cannot discover or resolve it. skl list --from cowork lists only locally stored local_… sessions. Passing the original cse_… session ID directly also fails:

$ skl view <cse-session-id> --from cowork --no-pager
Error: no local cowork session matches `<cse-session-id>` (try `skl list`)

I expected txcript either to discover Cowork sessions that Claude Desktop can open or to provide a supported remote-Cowork source analogous to the live claude_chat source. At minimum, the CLI should clearly explain that the cowork harness is local-only and direct users to a supported path for cloud-backed Cowork sessions.

Instead, the session is absent from discovery and cannot be addressed by its source ID. To sync it, I had to inspect Claude's authenticated session data, recover the transcript, and construct a separate local Cowork bridge. The bridge then appeared under a new local_… ID, but it is not the original source session.

There is a related but distinct fidelity problem after a session becomes available: attached and generated files are reduced to display labels rather than preserved as files. That is tracked separately in #62.

How to reproduce

1. In Claude Desktop, create or open a cloud-backed Cowork session whose URL or source record uses a cse_… ID.

2. Complete at least one turn and confirm that the session remains visible and openable in Claude Desktop.

3. List Cowork sessions:

   skl list --from cowork

4. Observe that the cloud-backed session is absent while locally stored Cowork sessions with local_… IDs are listed.

5. Try to address the source session directly:

   skl view <cse-session-id> --from cowork --no-pager

6. Observe:

   Error: no local cowork session matches `<cse-session-id>` (try `skl list`)
   

This was confirmed with a private, completed Cowork session containing 173 messages. I can provide the source session ID and additional diagnostics directly to the maintainers if useful; I have omitted the private identifier and session contents from this public report.
