Repository navigation
[GitHub integration] #103449
Description
Screenshot
What were you trying to do?
In Cowork, Claude cannot read from or write to my private GitHub repositories. . This blocks my workflows that create and update repos: creating a game repo from my template, builds in GitHub Actions, and new releases.
What happened instead?
The errors tell it to use a tool (add_repo) that doesn't exist in the session, and there is no other way to give the session access to a repo

The
add_repotool does exist. It's gated per account, not missing from Cowork. In #97926 I have two Max accounts on the same laptop, client and GitHub App install. On one, Cowork's claude-code-remote server exposes 9 tools, includinglist_repos,add_repoandregister_repo_root, and push works. On the other it exposes only the 6 trigger tools,CLAUDE_CODE_SESSION_ORIGINis unset, and the mode button reads "Chat and Cowork" instead of "Claude." Support suggested the broken account was never migrated to the merged Chat/Cowork interface.If you're hitting this, could you check: (1) Does your mode button tooltip say "Chat and Cowork" or "Claude"? (2) Is
CLAUDE_CODE_SESSION_ORIGINset in your Cowork session? If your results match, a 👍 or a comment on #97926 would help show this is an account-rollout problem.
