Cursor Product State and Context Record
Current product model
Cursor's January 2026 first-party agent guide describes a harness made of instructions, tools, and a selected model. It describes planning, code search, explicit file references, rules, skills, editing, terminal execution, tests, diff review, worktrees, and cloud agents.
The product can gather codebase context through search and can accept explicit references. Context remains selected and bounded. It is not complete knowledge of a repository.
Change path
The useful public mental model is:
request and constraints -> selected repository context -> model and agent tools -> proposed changes and commands -> human diff review -> tests and project checks -> durable Git history -> accountable acceptance.
Cursor's checkpoints and review surfaces can help a user inspect or reverse agent changes. They are product workflow aids, not a substitute for a repository's version history, branch protections, required reviews, or test evidence.
Data path
Cursor's data-use page says AI requests still pass through its backend, including when a user supplies an API key. It describes different handling under Privacy Mode, codebase indexing, embeddings and metadata, temporary caches, model-provider retention conditions, and possible use for improvement or training when Privacy Mode is disabled.
These are first-party statements about the service. A team must verify the settings, plan, provider selection, repositories, network path, organizational policy, and current legal terms that apply to its own account.
Confidence boundary
Product documentation can establish intended behavior and stated controls. It cannot establish that the correct files were selected, that a generated change is correct, that a command was safe, or that a repository owner should accept the result.
Every current feature statement needs a verification date because Cursor changes quickly.
