Command Creator

Command Creator

Create custom commands to automate repetitive tasks. This skill supports:

• Pi prompt templates - Markdown snippets invoked via /name in the editor (simpler, no configuration)
• OpenCode commands - Custom commands with advanced configuration (agents, models, shell injection)

When asked to create a command, first ask the user which system they're targeting.

Pi Prompt Templates

Pi prompt templates are simple Markdown files that expand in the editor when invoked.

Locations

Format

---
description: Review staged git changes
---
Review the staged changes (`git diff --cached`). Focus on:
- Bugs and logic errors
- Security issues
- Error handling gaps

Key points:

• Filename becomes command name: review.md → /review
• description in frontmatter is optional (defaults to first line)
• No special configuration required

Arguments

Supports positional arguments and slicing:

Example:

---
description: Create a React component
---
Create a React component named $1 with TypeScript and features: $@

Usage: /component Button "onClick handler" "disabled support"

Loading

• Discovery is non-recursive (no subdirectory scanning)
• Add via prompts array in settings if needed
• Disable with --no-prompt-templates

Example Pi Templates

Git review template (.pi/prompts/review.md):

---
description: Review staged changes
---
Review the staged changes (`git diff --cached`). Check for:
- Bugs and logic errors
- Security vulnerabilities
- Performance issues
- Code style inconsistencies

Component creation (.pi/prompts/component.md):

---
description: Create React component
---
Create a React component named $1 with TypeScript:
- Use functional components with hooks
- Export as default module
- Include PropTypes or TypeScript interface
$@

Usage: /component Button

OpenCode Commands

OpenCode commands are more powerful with JSON configuration, agent/model selection, and shell injection.

Quick Start

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"
    }
  }
}

Locations

Arguments

Same placeholders as Pi, plus OpenCode-specific features:

Shell Output Injection

Use backticks to inject bash command output (OpenCode only):

---
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.

Comparison: Pi vs OpenCode

Best Practices

1. Use descriptive names that don't conflict with built-ins
2. Keep prompts focused and specific - one task per template/command
3. Use arguments for reusable templates (Pi) and commands (OpenCode)
4. Include descriptions for autocomplete suggestions
5. For Pi: Keep it simple - no shell code or complex logic
6. For OpenCode: Leverage shell output for dynamic context
7. Include file references (@) for context-aware commands (OpenCode only)
8. Test your templates/commands after creating them
