Claude Code 2.1.292 fixes sandbox read-boundary cases

The release fixes sandboxed commands reading staged /ultrareview copies and a managed read-deny path case. It also adds an effort parameter to the Agent tool. Upgrade deployments relying on managed read restrictions, then test those restrictions on the configured path. Lower effort is a task setting to evaluate, with no guaranteed savings. ²

Relevant to: Managed Claude Code environments and owners of subagent configurations.
