About Opencode

OpenCode is an open-source AI coding agent for software development work. It is distributed as a GitHub repository under an open-source license and can be installed from the command line through several package managers, including npm, Homebrew, Scoop, Chocolatey, pacman, mise, and Nix. It also has a desktop application.

The agent includes two built-in agents that can be switched with the Tab key. The default build agent has full access for development work. The plan agent is read-only and is intended for analysis and code exploration. It denies file edits by default and asks permission before running bash commands. The source describes it as suited to exploring unfamiliar codebases or planning changes. A general subagent handles complex searches and multistep tasks and can be invoked with @general.
