Composer 2 is an advanced AI agent within the Cursor IDE that autonomously handles complex software development tasks. It can plan, build, test, and demo features end-to-end, allowing developers to focus on architecture and decision-making. It integrates deeply with your codebase and runs parallel tasks using cloud agents.

How to use Composer 2 by Cursor?
Install the Cursor IDE and activate Composer 2. Describe a feature or task in natural language, such as 'Build a mission control interface' or 'Create a dashboard for research data.' The agent will analyze your codebase, draft implementation plans, write code, run tests, and provide a demo. You can review its work, ask questions, and iterate, effectively offloading implementation while maintaining oversight.
Composer 2 by Cursor 's Core Features
Autonomous Task Execution: Composer 2 agents work independently to turn ideas into code. They can plan, write, test, and deploy features, running in parallel on cloud infrastructure to accelerate development cycles.
Deep Codebase Understanding: The agent indexes and comprehends your entire codebase, regardless of scale or complexity. It can answer contextual questions about architecture and locate specific code definitions.
Multi-Model Intelligence: Leverages the best frontier AI models (GPT-5.2, Opus 4.6, Gemini 3 Pro, Grok Code) for different tasks, ensuring high accuracy in code generation, planning, and problem-solving.
Integrated Development Workflow: Works seamlessly within the Cursor IDE. It can be triggered via chat (Cmd+K), reviews PRs in GitHub, collaborates in Slack, and operates in the terminal, fitting into existing developer workflows.
Plan-First Development: Before coding, the agent creates detailed implementation plans (like a PRD) in markdown files. This allows for upfront review and alignment, reducing wasted effort on incorrect implementations.
Cloud Agent Infrastructure: Tasks can be offloaded to run on dedicated cloud computers, allowing for parallel execution of long-running jobs like testing or data processing without taxing your local machine.
Contextual Collaboration: The agent maintains context across conversations and files. It can ask clarifying questions, suggest alternatives, and incorporate feedback iteratively, acting as a true collaborative partner.
Composer 2 by Cursor 's Use Cases
Senior Developer/Architect: Accelerates prototyping and exploration of new features. Describe a high-level concept and let Composer 2 build a working proof-of-concept, freeing you to focus on system design and integration.
Solo Founder/Indie Hacker: Acts as a full-stack development partner. Can build entire landing pages, dashboards, or backend services from a description, dramatically reducing time-to-market for MVPs with limited resources.
Engineering Team Lead: Improves team productivity and consistency. Use Composer 2 to generate boilerplate code, implement common patterns, or automate repetitive tasks, ensuring junior developers have high-quality starting points.
Data Scientist/Bioinformatician: Bridges the gap between analysis and production. Describe a data pipeline or visualization need, and the agent can build the necessary Python scripts, APIs, and interactive dashboards.
Product Manager: Facilitates technical discovery and specification. Work with Composer 2 to create interactive mockups or detailed technical plans (feature-prd.md) to communicate requirements clearly to engineering teams.
Open Source Maintainer: Manages project upkeep efficiently. The agent can help triage issues, suggest fixes, review pull requests, and implement non-critical features, reducing maintenance burden.
