Cursor Deep Dive - Hidden Prompts and Tools REVEALED!
AI Summary
Summary of Video Transcript
Overview
- Kevin introduces a series on understanding the inner workings of Cursor, a coding tool.
- The series aims to teach how coding agents work to improve the use of Cursor and similar tools.
- Focus is on the “composer agent” within Cursor.
How Agents Work
- Agents have three phases: retrieval, call, and memory.
- Retrieval involves getting information from the LLM (Language Learning Model).
- Calls are made using tools, and memory involves reading/writing information back and forth.
Coding Agent Details
- The process involves clarifying tasks with the LLM through back-and-forth communication.
- Context is crucial, including code snippets, rules, documentation, and web searches.
- Tools help the LLM gather more information and perform tasks like editing code or running tests.
Prompt Structure
- System prompt: Defined by the developer, instructs the LLM on its role.
- User prompt: Specific to the user’s request, includes details like sample code and task description.
- Tools: Specific functions the agent can use to complete tasks.
Tools Used by Cursor
- Cursor uses 15 tools, each with a name, description, and input schema.
- Tools are called through JSON objects that specify the tool name and parameters.
- Tools include listing directory contents, fuzzy name searches, reading files, editing files, and more.
Editing and Creating Files
- Editing involves the LLM suggesting changes to existing files.
- Creating new files involves the LLM specifying the content and name of the new file.
- Both processes can be done in a brute force way or through diffs for efficiency.
Terminal Commands and Custom Tools
- Terminal commands can be run and their output captured.
- MCP (Master Control Program) allows users to add custom tools for Cursor to use.
Conclusion
- Kevin emphasizes that building an agent is not overly complex and encourages viewers to try.
- He plans to discuss building an open-source version of Cursor in future videos.
