How it works
Cursor is a code editor with artificial intelligence features and an agent focused on development tasks. The official documentation describes the product as a tool to understand a codebase, plan features, fix bugs and review changes. The available set can evolve, so check the Cursor documentation for current details.
In the agent flow, the person describes a goal and the system can search the repository, edit files and, according to permissions, run commands or checks. The agent uses a model, tools and context instructions. Changes appear for review, allowing the person to inspect the diff and accept or discard the work.
This is different from an autocomplete suggestion. Autocomplete offers a continuation while someone writes; an agent can carry out a task that spans multiple steps and files. Cursor documentation also distinguishes modes intended for tasks that change code from those focused on exploring or answering without editing.
Execution features require attention. Before allowing commands, check what will be executed and whether the agent has access to files, network or secrets. The interface makes work easier, but the team remains responsible for validating the change and the impact of any action on the project.
Practical example
Imagine a developer wants to add a sorting option to a product list. In Cursor, they can explain the expected behavior and point to the relevant screen or component. The agent can look for related files, propose changes across multiple files and prepare tests, if context and tools are sufficient.
The developer reviews the diff: check if sorting works in expected cases, if UI state is preserved and if tests reflect requirements. They can also request specific adjustments, such as keeping compatibility with an existing API or not touching configuration files.
If the task involves a broad change, it is better to establish steps and acceptance criteria. Run relevant tests and compare behavior before and after. A written conclusion from the agent does not replace actual execution of checks nor review of the implementation.
What it is for
Cursor can support exploring a codebase, implementing features, fixing bugs, generating tests and reviewing changes. It brings code editing and AI assistance into the development flow, allowing switching between point suggestions and tasks delegated to an agent.
The tool tends to be more useful when the request includes context, limits and a verifiable outcome. For example, say which files are relevant, which behaviors must not change and which test should pass. For sensitive projects, configure permissions carefully and do not share secrets in the prompt.
Cursor does not guarantee correct or safe code. Review changes, dependencies and commands, especially before merging into a main branch or production. Suitability depends on the repository, the configured model, team rules and the data policy applicable to the organization.
Difference between Cursor and code autocomplete
Autocomplete suggests snippets while the person types. Cursor also offers an agent that can search the project, make larger edits and use development tools. They are different forms of assistance, and human review remains necessary in both.
