How to Use opencode
Install OpenCode: Install using one of these methods: npm install -g opencode-ai, bun install -g opencode-ai, brew install sst/tap/opencode, or paru -S opencode-bin
Configure AI Provider: Run 'opencode auth login' and select your preferred provider (Anthropic/Claude recommended). Follow authentication steps to set up API access
Navigate to Project: Change directory to your project folder before running OpenCode to ensure proper context
Initialize Project: Run 'opencode init' to create AGENTS.md file that helps OpenCode understand your project structure and patterns
Select Model: Use '/models' command to view and select available AI models from your configured provider
Launch TUI: Run 'opencode' without arguments to start the Terminal User Interface (TUI). Use Cmd+Esc (Mac) or Ctrl+Esc (Windows/Linux) for quick launch
Choose Agent Type: Select between Plan agent (for analysis without code changes) or Build agent (for implementing changes). Switch using Tab key
Interact with OpenCode: Ask questions, request code changes, or get explanations. Use @ key to fuzzy search files in project
Customize Experience: Modify theme using Ctrl+x + t or customize settings in ~/.config/opencode/config.yaml
Use File References: Insert file references using Cmd+Option+K (Mac) or Alt+Ctrl+K (Windows/Linux) with format @File#L37-42
