Claude Code v2.1.202: Dynamic Workflow Size & OpenTelemetry Attributes

v2.1.202 introduces a 'Dynamic workflow size' setting in /config, letting users choose small/medium/large as a suggestion for agent count in dynamic workflows (not a hard limit). It also adds workflow.run_id and workflow.name OpenTelemetry attributes to workflow-generated agents, enabling workflow activity reconstruction from OTel data. Bug fixes include: crash on accept/cancel during Ctrl+R history search, /rename in background sessions reverting after task restart, brief handshake failures during mTLS certificate rotation, ignored Remote Control commands and untitled images/files, non-clickable login URLs in SSH for Claude auth/mcp login, chat opening from agent failing due to background agent conflicts, unicode quote escaping errors in workflow scripts, infinite microphone retry on failure, wrong permission mode in remote control, slow session restore in repos with many git worktrees, installer abort on network interruption, and duplicate commands from reloading already-loaded skills. /workflows agent list UI improved: wider titles, dedicated time column, shorter model names, removed per-line tool call count. MCP error messages improved: missing type field now suggests 'type: http' instead of misleading 'command: expected string'. /review reverted to single quick review; use /code-review for multi-agent reviews. Developers should note these changes to optimize workflow configuration and debugging.
