Request for "Atomic Execution Mode": A Native Orchestrator for Plan-Build-Test-Commit Cycles

Feature request for product/service

Cursor IDE

Describe the request

Currently, maintaining a professional “Agentic Atomicity” workflow requires significant manual overhead. We need a native Orchestrator that bridges Plan Mode and Composer/Agent Mode to enforce a “One-Task-at-a-Time” discipline.

Key Requirements:

  1. Self-Contained Plan Hand-off: When a plan is finalized in Plan Mode, it should generate a “Context-Locked Task List.” A new implementation agent should be able to adopt a single task without inheriting the bloated chat history of the planning phase.
  2. Atomic Execution Gates: Add a toggle in Composer/Agent Mode that prevents the agent from starting Task B until:
  • Test Gate: A specific test command (e.g., npm test) returns a “Green” status.
  • Commit Gate: A Git commit is executed for the current changes.
  1. Scope Guardrails: A native setting to restrict the agent’s write access ONLY to files identified in the current atomic task, preventing “file sprawl” or unrelated refactors.
  2. Multi-Agent Personas: Native support for the “Architect-Builder-Auditor” lifecycle where specialized models (e.g., o1 for planning, Sonnet for building) pass state to each other automatically.

Why this is needed:
To move beyond the “vibe coding” era where AI agents create massive, unverified changes that lead to “hallucinated dependencies” and fragile codebases. Professional engineering in 2026 requires deterministic validation gates. Without a native orchestrator to enforce atomicity, we spend more time “cleaning up” after the AI than actually building features. We need Cursor to act as a disciplined engineering partner, not just a fast typewriter.

Hey, thanks for the detailed feature request.

Some of the features you mentioned are partly available already:

  • Plan Mode creates a plan before it runs, breaks work into to-dos with dependencies, and lets you edit the plan before it builds: Planning | Cursor Docs
  • Custom Slash Commands let you create a workflow with tool limits, like search-only or only specific files: Commands | Cursor Docs

That said, specific features like Test/Commit Gates and automatically limiting file access per task aren’t supported yet.

I’ve logged the request for the team.
