Cursor is an IDE-native coding agent that plans and executes multi-step tasks across entire codebases — editing files, running terminal commands, and spinning up parallel agents without requiring approval at every step. The vendor describes cloud agents that use their own compute to build, test, and demo features end to end, with the result queued for your review rather than interrupting your flow. That model works well for repetitive, well-scoped tasks: boilerplate generation, dependency migrations, test scaffolding. Where it starts to strain is open-ended architectural decisions — the agent can produce a plan, but if your codebase has undocumented assumptions baked into fifteen files, the output requires real scrutiny before it ships. Teams handling high-stakes refactors report adding review checkpoints that partially offset the autonomy gain.
