# Commands Reference
Complete list of available commands and their usage.
## Slash Commands
### `/opencode:plan`
Structured analysis and planning mode (default behavior).
```
/opencode:plan create a Python fibonacci generator
/opencode:plan test this function: [code]
```
### `/opencode:build`
Immediate execution mode for direct implementation.
```
/opencode:build create a simple web server
/opencode:build implement this API endpoint: [spec]
```
### `/opencode:help`
Show help information and available tools.
```
/opencode:help
/opencode:help ask-opencode
```
### `/opencode:ping`
Test connectivity with OpenCode.
```
/opencode:ping
/opencode:ping "Custom message"
```
## Command Structure
```
/opencode:<tool> [options] <arguments>
```
- **tool**: The action to perform (plan, build, help, ping)
- **options**: Optional flags (coming soon)
- **arguments**: Input text, files, or questions
## Natural Language Alternative
Instead of slash commands, you can use natural language:
- "Use opencode to analyze index.js"
- "Ask opencode to create a test file"
- "Have opencode explain this error"
## File Patterns
### Single File
```
@README.md
@src/index.js
@test/unit.test.ts
```
### Multiple Files
```
@file1.js @file2.js @file3.js
```
### Wildcards
```
@*.json # All JSON files in current directory
@src/*.js # All JS files in src
@**/*.test.js # All test files recursively
```
### Directory
```
@src/ # All files in src
@test/unit/ # All files in test/unit
```
## Advanced Usage
### Combining Files and Questions
```
/opencode:plan @package.json @src/index.js is the entry point configured correctly?
```
### Complex Queries
```
/opencode:plan @src/**/*.js @test/**/*.test.js what's the test coverage?
```
### Code Generation
```
/opencode:build @models/user.js generate TypeScript types for this model
```
## Tips
1. **Start Simple**: Begin with single files before using patterns
2. **Be Specific**: Clear questions get better answers
3. **Use Context**: Include relevant files for better analysis
4. **Iterate**: Refine your queries based on responses
