Summary

Claude Code v2.1.146 (released 2026-05-21) is a platform-stability and cross-platform-parity release. The headline change is renaming /simplify to /code-review with an optional effort level (/code-review high). Beyond that, the release closes a Windows regression from v2.1.124 where PowerShell failed with winget/Store installs, fixes MCP pagination (items past page 1 were silently dropped on paginating servers), and resolves several multi-agent issues: CLAUDE_CODE_SUBAGENT_MODEL not forwarding to child processes, and backgrounded sessions re-prompting for already-granted tool permissions. Enterprise policy enforcement for forceLoginOrgUUID and forceLoginMethod was broken against third-party-provider sessions — now fixed.

Implications

Feeds the coding-agent landscape and agentic orchestration patterns threads:

• The /code-review rename with effort levels is a UX signal that Anthropic is formalizing code review as a first-class workflow, not just a slash-command alias
• MCP pagination fix is load-bearing for any server exposing large resource lists; silent truncation was a latent data-loss bug for orchestration setups
• The CLAUDE_CODE_SUBAGENT_MODEL forwarding fix matters for multi-agent pipelines that route different sub-tasks to different model tiers — the regression broke model routing in child processes
• Enterprise policy enforcement fixes tighten the institutional deployment story ahead of broader enterprise rollout
