Cursor adds auto-review mode to cut prompts, boost safety

Cursor has just rolled out auto-review mode, aiming to reduce approval prompts while keeping agent tool calls safer. A new classifier subagent reviews unsandboxed or non-allowlisted actions, deciding whether to proceed, reroute, or ask you first.

TL;DR

  • Auto-review mode in Cursor: Agents can run tool calls with fewer approval prompts; marketed as “safer execution”
  • Allowlist + sandboxing checks: Actions outside allowlist or unsandboxable routed to a classifier subagent
  • Classifier subagent decisions: Allow the tool call, try an alternative approach, or request approval
  • Mixed community reaction: enthusiasm for fewer prompts; skepticism about shifting jailbreak targets to the classifier
  • Calls for stress-testing: “fewer approval prompts” and “safer” execution seen as needing validation
  • Broader agent-tooling tension: approval gates slow work; fewer gates can reduce trust; tradeoff depends on classifier performance

Cursor announced on X that auto-review mode is now available in Cursor, a feature the company claims lets agents run tool calls with fewer approval prompts and "safer execution."

According to Cursor, similar to Claude Code's Auto Mode to curb approval fatigue, agent actions outside a user's allowlist, or actions that cannot be sandboxed, are routed to a "classifier subagent." That separate agent then decides whether to allow the tool call, try a different approach, or ask for approval.
