Cursor · coding editor and agent product

Cursor

Official documentation

Cursor brings a coding assistant into the editor, where a question about a repository can lead directly to a proposed change. Agent searches files, edits code and runs commands; Ask supports read-only exploration, and planning helps work through a larger change before building it. That makes it useful for following an unfamiliar code path, implementing a feature or iterating on a bug fix while keeping the diff in view. The product also has CLI and cloud-agent surfaces. Choose the execution surface and repository access together: the editor workflow and a more autonomous cloud task do not have identical boundaries.

In this profile

When it fits

Useful for

  • Exploring and changing an existing codebase with editor context
  • Working through a bounded fix whose diff and regression checks can be reviewed

Limits to consider

  • Assuming local editing means no code context leaves the machine
  • Granting a cloud agent production access before defining the repository task

Capabilities and platforms

  • Agent searches repository files, edits code and runs commands
  • Ask supports read-only code exploration
  • CLI and cloud-agent surfaces extend the product beyond editor interaction

Where it runs

  • Editor
  • CLI
  • Cloud-agent surface

Access and setup

Cursor account and applicable product entitlement; repository, command and cloud-agent access depend on the chosen run mode and organization controls.

Current access and pricing
  1. Open an authorized repository using the official editor or CLI setup. Save the current state and create a disposable branch so you can review the proposed changes together.
  2. Use Ask to locate the relevant code, callers and existing tests. For a larger change, review a plan before switching to implementation; inspect the active command and access controls as well.
  3. Give Agent a specific behavior to change, the expected result and the checks that matter. Review the diff alongside the command results, then carry the accepted patch through the repository’s normal review process.

Proposed exercise · not hands-on tested

Repair a synthetic parsing bug

Input

A disposable repository with a known parsing failure, its expected result and at least one ordinary input that already works.

  1. Use Ask to follow the failing input through the parser and its callers. Locate the existing tests and identify the first point where the actual value differs from the expected one.
  2. In an appropriate edit mode, request the smallest fix and a regression test for that input. Keep the existing successful case and avoid a broader parser rewrite unless the failure requires it.
  3. Run the parser checks and inspect the complete diff. Confirm that the regression asserts the intended value and that unrelated files or existing assertions were not changed to make it pass.

Artifact to inspect

A proposed parser patch, a regression test for the supplied input and the results of the relevant existing checks.

What to verify

The previously failing input should produce the expected value while ordinary inputs retain their behavior. Review the actual assertion and changed code together before accepting the patch.

Data handling and permissions

Cursor's Privacy Mode addresses model-training use, rather than promising that repository context never leaves the computer. The editor, CLI and cloud-agent routes should be assessed as different execution surfaces, particularly where commands, credentials or repository material can be reached. Check the current privacy documentation and organization controls before opening confidential code. A disposable branch makes edits reviewable but is not a data-transmission boundary. Keep production credentials outside the proposed parsing exercise, inspect command output for unintended exposure and review any cloud-agent access separately. This documentation-based profile does not establish the behavior of a particular account configuration or certify generated code as safe to merge.

Other options

Codex
Consider the existing CLI guide for a terminal-centered repository workflow.
Herdr
A complement for supervising several coding-agent sessions, rather than another model or editor.

Sources and scope

Documentation-based product profile; no hands-on testing. The proposed workflow is an authored exercise, not a verified outcome or a practical guide. Capabilities and policy statements describe vendor documentation checked October 2, 2026; task-fit comparisons are editorial judgments. Plan, region, administrator and interface limits may apply.
