OpenCode Tutorial

OpenCode is a command-line (CLI) based AI programming Agent that can understand project context and automatically execute development tasks.

OpenCode is not a simple code generator, but an intelligent agent tool withUnderstanding + Executioncapabilities.

OpenCode runs in the terminal, not in an IDE.

OpenCode is an Agent (intelligent agent tool), not a Chat (chat tool).

The New Era of AI Programming

The traditional software development model was: developers write code, and tools provide assistance.

In the AI Agent model, the development approach is changing:

  • Developers describe requirements
  • AI is responsible for implementing the code
  • Developers are responsible for review and decision-making

The emergence of such tools marks a shift in development mode from hand-writing code to directing AI to write code.

Compared toGitHub Copilotcode completion tools like these, OpenCode goes a step further. It can not only generate code, but also actually execute tasks.

  • Can understand basic syntax, functions, conditional statements, and loops
  • Have written simple projects or practice code
  • Want to leverage AI to improve development efficiency and engineering skills
  • Independent developers or engineers who need to maintain projects long-term
  • Technical leads or core team members

Prerequisite Skills Required

  • Basic programming skills (able to read and write simple code)
  • Basic code reading and comprehension skills
  • Can use common development tools (editors, command line)
  • Have a basic understanding of project structure (directories, module organization)
  • Willing to understand code, rather than completely relying on AI
