Claude Code 2.1.202

This release adds dynamic workflow size configuration, improves OpenTelemetry telemetry with workflow attributes, and fixes numerous crashes and failures in workflow execution, session management, remote control, voice dictation, and file handling. It also enhances UI layouts and error messaging for better developer experience.

  • Added a "Dynamic workflow size" setting in /config for controlling how large Claude generally makes dynamic workflows (small/medium/large agent counts) — an advisory guideline, not an enforced cap
  • Added workflow.run_id and workflow.name OpenTelemetry attributes to telemetry emitted by workflow-spawned agents, so a workflow run's activity can be reconstructed from OTel data
  • Fixed a crash in the inline Ctrl+R history search when accepting or cancelling while the search was still scanning the history file
  • Fixed /rename on background sessions being reverted when the job restarts, which broke addressing the session by its new name
  • Fixed transient mTLS handshake failures when settings were re-applied during an in-place client certificate rotation
  • Fixed commands sent from Remote Control (mobile/web) into an interactive session failing with "Unknown command"
  • Fixed images and files sent from the Remote Control mobile or web app without a caption being silently dropped
  • Fixed the sign-in URL printed by claude auth login and claude mcp login --no-browser not being reliably clickable when it wraps over SSH — it is now emitted as a single hyperlink
  • Fixed opening a chat from claude agents sometimes failing with "currently running as a background agent" followed by a worker crash/respawn loop
  • Fixed workflow scripts with unicode quote escapes in strings being corrupted before parsing; workflow parse errors now show the offending line instead of always blaming TypeScript
  • Fixed voice dictation retrying in an unbounded loop when the microphone or audio recorder fails — repeated capture failures now pause voice input
  • Fixed /remote-control sessions showing the wrong permission mode in the mobile and web apps
  • Fixed resuming a session by name, or opening the resume picker, taking minutes and using a large amount of memory in repositories with many git worktrees
  • Fixed installer and updater downloads failing immediately with "aborted" when a proxy or network drops the connection mid-download — transient connection drops now retry
  • Fixed re-invoking an already-loaded skill appending a duplicate copy of its instructions to context
  • Improved /workflows agent list layout: wider titles, a dedicated time column, shorter model names, and no per-row tool-call counts
  • Improved MCP error messages: clearer error when a server config has url but no type, suggesting "type": "http" instead of the misleading "command: expected string"
  • Changed /review <pr> back to a fast single-pass review; use /code-review <level> <pr#> for the multi-agent review at a chosen effort level
