Command Creator

Create custom OpenCode commands to automate repetitive tasks. Custom commands let you define prompts that run when you type /command-name in the TUI.

Quick Start

Create a markdown file in .opencode/commands/ or configure via opencode.jsonc:

Markdown format (.opencode/commands/test.md):

---
description: Run tests with coverage
agent: build
model: anthropic/claude-3-5-sonnet-20241022
---
Run the full test suite with coverage report and show any failures.

JSON format (opencode.jsonc):

{
  "command": {
    "test": {
      "template": "Run the full test suite with coverage report and show any failures.",
      "description": "Run tests with coverage",
      "agent": "build",
      "model": "anthropic/claude-3-5-sonnet-20241022"
    }
  }
}

Command Locations

Arguments

Pass dynamic values using placeholders:

Example:

---
description: Create a component
---
Create a React component named $ARGUMENTS with TypeScript.

Usage: /create-component Button

Shell Output Injection

Use backticks to inject bash command output:

---
description: Analyze coverage
---
Current test results:
!`npm test`
Suggest improvements based on these results.

File References

Include file contents using @:

---
description: Review component
---
Review @src/components/Button.tsx for performance issues.

Options Reference

Built-in Commands

OpenCode includes: /init, /undo, /redo, /share, /help. Custom commands with the same name override built-ins.

Best Practices

1. •Use descriptive names that don't conflict with built-ins
2. •Keep prompts focused and specific
3. •Use arguments for reusable commands
4. •Leverage shell output for dynamic context
5. •Include file references for context-aware commands
