# OpenCode

The open-source AI coding agent OpenCode ships two built-in agents: build, the default with full development access, and plan, which denies file edits by default and asks permission before running bash commands, suited to exploring unfamiliar codebases or planning changes. A general subagent handles complex searches and multistep tasks and can be invoked with @general in a message. Installation covers a shell script, npm, Homebrew, pacman, mise and Nix, plus a desktop app download.

The open-source coding agent OpenCode ships two built-in agents: build, the default full-access agent for development work, and plan, a read-only agent that denies file edits by default and asks permission before running bash commands, aimed at exploring unfamiliar codebases or planning changes. A Tab key switches between them, and a general subagent invoked with @general handles complex searches and multistep tasks. Installation spans a shell script, npm, brew, scoop, pacman, mise and nix, with a desktop application also available.

Starting with Agents SDK 0.28.0, the experimental OpenCodeHarness supports OpenCode 2.0, letting OpenCode run inside a plain Durable Object with sessions stored in SQLite and Lifecycle jobs that wake interrupted work after eviction. Previously this session state and interruption recovery had to be arranged separately. The agents/models/opencode provider connects OpenCode to Workers AI through the AI binding, and plugins add custom tools, remote MCP servers, and skills.
