Renowned AI code editor Cursor has officially released version 1.6 today, introducing multiple innovative features aimed at enhancing developers' productivity and team collaboration efficiency. According to official announcements and community feedback, this update particularly emphasizes the practicality of custom commands, which have already proven significant value in reusability of prompts within internal teams.

Cursor, as an AI-based code editing tool, has been favored by developers since its launch for its intelligent agent and context-aware capabilities. The core highlight of the 1.6 version is the custom command feature, allowing users to create and use custom commands directly within the editor. These commands enable developers to define reusable prompt templates and quickly access them with a simple slash (/) prefix, such as running a code checker, fixing compilation errors, or generating detailed pull request (PR) descriptions. This design is especially suitable for team environments,

According to official information, these commands have been widely used within the Cursor development team to standardize workflows and improve the efficiency of code reviews and submissions.

In addition to custom commands, version 1.6 also optimizes the performance of the Agent Terminal, making it faster and more reliable. This improvement solves issues of delay and instability that may have occurred in previous versions, allowing the AI agent to be more responsive when handling complex tasks. At the same time, the version update adds official support for MCP (Model Context Protocol) resources. MCP is an emerging protocol used to connect external tools and data sources to AI models. This integration allows Cursor to seamlessly access more resources, such as external APIs or custom servers, thus expanding the functional boundaries of the AI agent. Developers can authenticate through environment variables or OAuth and enable auto-run mode, allowing the agent to call these tools without additional confirmation.

Another notable feature is the new /summarize command. This command allows users to summarize the current context at any time, especially useful for long conversation scenarios. It helps the AI compress historical information, freeing up context window space without creating a new chat session. This is particularly useful for handling large codebases or multi-round iterative tasks, avoiding performance degradation caused by information overload.

Soon after the release, several developers shared their initial experiences on social platforms, praising the custom commands for "greatly improving efficiency," and pointing out that the /summarize feature is "a great enhancement" in long sessions. Some early testers also mentioned that the optimization of the agent terminal significantly improved performance on resource-limited devices, such as running smoothly on a MacBook Air with 16GB RAM. In addition, the official changelog shows that Cursor 1.6 includes other auxiliary improvements, such as more accurate codebase search and PR index summaries, further enhancing the tool's practicality.

The release of Cursor 1.6 marks an evolution of AI-assisted programming tools toward greater intelligence and modularity. The developer community expects these features to further promote team collaboration, especially in open-source projects and enterprise environments. The Cursor team stated that this version has begun to be pushed to all users, and developers are advised to enable the Nightly mode via the settings menu to get the latest iteration, but they should be aware of potential resource consumption.

The release of Cursor 1.6 comes at a time of fierce competition in the AI development tool market, where similar tools like Claude and other agent frameworks have also introduced similar protocol support. In the future, the expansion of MCP applications may become an industry standard, driving more external integrations. For more details, please refer to the changelog on the official website of Cursor.
