Claude Code 2.1.267 adds maxEffortLevel cap and per-request system prompt re-rendering
ClaudeCodeLog · x · 2026-09-10
Claude Code CLI shipped version 2.1.267 with 53 changes.
New features
- maxEffortLevel setting (top-level or per-model under modelSettings) caps the effort level across every provider including Bedrock, Vertex and Foundry, enabling admin-level limits while users can still pick lower levels.
- --system-prompt-snapshot off renders the system prompt fresh on every request instead of reusing the conversation's recorded prompt, speeding up prompt iteration.
Fixes
- Fixed cloud Cowork scheduled tasks failing at startup for organizations whose managed settings require sandboxing.
- Fixed /context and other local command output rendering blank on mobile clients.
- Fixed shift+enter and option+backspace not working after reconnecting to a tmux/ssh session inside an agent view.
- Fixed the dim last-prompt header not appearing at the top of the conversation in fullscreen mode.
- Workflow agent() calls with large output now run safety checks in auto mode instead of being rejected.
