Key Concepts Overview

Section titled “Key Concepts Overview”

Agent Modes Mastery

Section titled “Agent Modes Mastery”

Cursor’s four modes each serve distinct purposes:

// Agent Mode Example - Autonomous multi-file refactoring
"Refactor the entire authentication system to use OAuth 2.0"
// Agent will: analyze, plan, modify multiple files, update tests


// Ask Mode Example - Understanding before changing
"How does the current authentication system work?"
// Ask will: search codebase, explain architecture, no modifications


// Manual Mode Example - Precise, controlled edits
"Update only the login function in auth.ts"
// Manual will: edit specified file only, no exploration


// Custom Mode Example - Specialized workflow
"Run security audit and fix issues"
// Custom will: use only configured tools for security tasks

Performance at Scale

Section titled “Performance at Scale”

Working with large codebases requires specific optimizations:

  • Incremental indexing with 5-minute update cycles
  • Memory management configurations for 100K+ LOC projects
  • Selective context strategies to reduce token usage
  • Multi-root workspaces for monorepo architectures

Security & Compliance

Section titled “Security & Compliance”

Enterprise environments demand rigorous security:

  • Privacy Mode enforcement across teams
  • SSO/SCIM integration for user management
  • Audit trails for AI-assisted changes
  • Secrets management best practices

Success Stories

Section titled “Success Stories”

Enterprise Migration at Scale

TechCorp used advanced Cursor techniques to migrate their 2M LOC monolith to microservices in 3 months instead of the estimated 12 months. Key techniques: custom MCP servers for dependency analysis, multi-repo workflows, and automated testing loops.

AI-Powered Code Reviews

FinanceApp reduced security vulnerabilities by 85% using custom rules, automated security scanning MCP servers, and team-wide enforcement of coding standards through shared Cursor configurations.
