Claude Code v2.1.202

What's changed

• 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
