What
Five names were added to the list of operations Claude Code tracks:
sdk_claim_session
self_hosted_agent_files
ccs_skill_read
ccs_skill_render
auth_sibling_login_adopt
By their names, these cover claiming a session through the SDK (the library for running Claude Code from other programs), files for self-hosted agents, reading and rendering skills in cloud sessions, and adopting a login from a sibling.
Why
These operations can now be tracked by name like the others on the list.
