Background agent is a software agent that completes assigned tasks asynchronously without requiring a user to stay active. In software engineering, it can run in a local process or isolated cloud environment to change code, run tests, and report results. Its defining feature is background execution, not a specific AI model, vendor, or hosting location.
Background Agent
What Is a Background Agent?
A background agent is a software agent that completes an assigned task asynchronously, so a developer does not need to wait or keep a session open. Unlike a passive background job, it can inspect context, make decisions, take actions, and return a report or code change.
How Background Agents Work
Background coding agents usually follow a controlled task lifecycle.
- A chat request, issue, pull request, schedule, or webhook triggers work.
- The system creates a workspace, often an isolated sandbox.
- The agent reads relevant code, instructions, and task context.
- It edits code, runs tests, and saves logs or commits.
- It returns artifacts for a person to review.
Background Agent vs. Local Coding Agent
A cloud agent is commonly a background agent, but the terms are not identical.
| Area | Background agent | Local coding agent |
|---|---|---|
| Execution | Runs asynchronously, locally or in the cloud | Runs in an active local workspace |
| Attention | Developer can work on something else | Usually needs active supervision |
| Review | Returns a diff, logs, or pull request | Changes appear directly in the workspace |
Products may call these Cursor background agents or Cursor cloud agents, but capabilities and safeguards vary by product.
Benefits of Background Agents
They are useful for bounded, repeatable engineering work.
- Run independent tasks in parallel.
- Protect developer focus during testing or investigation.
- Create traceable commits, logs, and pull requests.
- Use isolated environments for safer experimentation.
Practical Limits and Risks
Autonomy does not remove the need for engineering judgment.
- An agent can act on incorrect assumptions.
- Broad repository or credential access increases risk.
- Parallel changes can conflict, and flaky tests can mislead.
- Long tasks can consume time and compute budget.
Best Practices for Background Coding Agents
Use clear boundaries and keep humans responsible for release decisions.
- Define one narrow task and measurable acceptance criteria.
- Apply least-privilege access and time limits.
- Require tests, logs, and a reviewable diff.
- Review changes before merging or deploying.
Background Agents in Emergent
Emergent applies agentic coding to app development: users describe an app or change in natural language, while autonomous agents implement, test, integrate, and deploy it. Understanding the role of a code agent helps teams set the right review and access controls.

What are background agents in Cursor?
In Cursor, background agents are agents that can work on coding tasks asynchronously, commonly in a separate remote environment, then return changes and results for review.
How do Cursor background agents work?
They receive a task, prepare a workspace, inspect the repository, make changes, run available checks, and report their output. Exact triggers, permissions, and limits depend on the configured product plan and settings.
How do you use background agents in Cursor?
Give the agent a specific task with acceptance criteria, relevant files or issue context, and test expectations. Review the resulting diff and test output before merging.
Is a background agent the same as a cloud agent?
No. Background describes asynchronous execution. Cloud describes where work runs. A background agent may run in a cloud sandbox or on local infrastructure.
Is a background agent the same as a chatbot?
No. A chatbot mainly responds in conversation. A background agent can use tools and continue working after the initial request to produce software artifacts.
Are background agents safe to use with production code?
They can be used safely with strong controls, including isolated environments, least-privilege access, protected branches, test requirements, and human approval before production deployment.
