Claude Code 2.1.202-204 improves workflows and remote reliability

Claude Code 2.1.202 added a setting for the usual size of dynamic workflows, with small, medium, and large options for how many worker agents Claude should generally create. The setting is guidance, not a hard limit. Workflow-created agents now include `workflow.run_id` and `workflow.name` in telemetry, so a full workflow run can be pieced together later from recorded activity.

Most of the fixes are about preventing real work from getting interrupted or lost. Claude Code fixed crashes in history search, renamed background sessions reverting after restart, Remote Control commands failing, images or files from mobile or web Remote Control being dropped, wrapped SSH login links becoming hard to click, and background agent chats entering a crash-and-restart loop. The following 2.1.203 and 2.1.204 updates continued the same theme with login-expiry warnings, a clearer manual permission mode badge, fixes for slow macOS background session switching, and a headless-session hook issue that could leave remote workers idle long enough to be stopped.

Separate user reports also show that specific model choices, such as Claude Opus 4.6 with 1M context, may stop working even when the coding tool itself is otherwise improving.
