v2.1.202
2.1.202
Highlights:
- Added /config 'Dynamic workflow size' to set small/medium/large agent counts for predictable workflow scale
- Added workflow.run_id and workflow.name OTel attributes to reconstruct workflow run activity from telemetry
- Remote Control (mobile/web) stopped dropping images/files sent without captions; media now reliably delivered
CLI changelog
- 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
- … +6 more CLI changelog entries

System prompt changes
Notable changes:
- Claude no longer sees an unrelated Bun hot-update warning in the system prompt. This removes noisy, non-instructional text that could distract or be misinterpreted as task context, keeping Claude focused on the actual security/testing and harness rules.

Other prompt changes
- Grep is now recommended as the go‑to search tool and its output modes, head_limit, and offset behaviors are clarified in the tool description.
