# Nano - OpenCode Agents Project
A minimal project structure for creating and managing custom OpenCode agents.
## Project Structure
```
nano/
├── opencode.json # Main agent configuration
├── .opencode/agent/ # Custom agents (markdown format)
│ └── docs-writer.md # Documentation writer agent
├── prompts/ # Agent prompt files
│ ├── build.txt # Build agent prompt
│ ├── cleanup.txt # Cleanup agent prompt
│ ├── security.txt # Security auditor prompt
│ └── review.txt # Code review prompt
└── README.md # This file
```
## Available Agents
### Primary Agents
- **build**: Full development agent with all tools enabled
- **plan**: Analysis and planning agent (read-only)
### Subagents
- **@cleanup**: Repository cleanup and maintenance
- **@security**: Security auditing and vulnerability assessment
- **@docs-writer**: Technical writing and documentation
- **@review**: Code review and quality assessment
## Usage
### Switching Between Primary Agents
Use `Tab` key to cycle between `build` and `plan` agents.
### Using Subagents
Mention subagents with `@` in your messages:
```
@cleanup help me clean up this repository
@security audit this code for vulnerabilities
@docs-writer create documentation for this API
@review review my recent changes
```
## Configuration
### Adding New Agents
1. **JSON Configuration**: Edit `opencode.json`
2. **Markdown Files**: Add new `.md` files to `.opencode/agent/`
3. **Prompt Files**: Add corresponding prompts to `prompts/`
### Agent Types
- **Primary**: Main agents you interact with directly
- **Subagent**: Specialized agents invoked for specific tasks
## Customization
### Models
Each agent can use different models optimized for their tasks:
- Fast models for planning and analysis
- Capable models for implementation
- Specialized models for specific domains
### Tools & Permissions
Configure which tools each agent can access:
- File operations (read, write, edit)
- System commands (bash)
- Web access (webfetch)
- Custom permissions and restrictions
### Temperature
Control creativity vs. determinism:
- 0.0-0.2: Focused, analytical tasks
- 0.3-0.5: Balanced development work
- 0.6-1.0: Creative and exploratory tasks
## Examples
### Repository Cleanup
```bash
@cleanup analyze this repository and suggest cleanup
```
### Security Audit
```bash
@security check for security vulnerabilities in this code
```
### Documentation Generation
```bash
@docs-writer create API documentation for this module
```
### Code Review
```bash
@review review my recent commits for best practices
```
## Development
### Creating New Agents
Use OpenCode CLI to create new agents:
```bash
opencode agent create
```
### Testing Agents
Test agents in isolation before integrating:
```bash
@new-agent test this functionality
```
### Agent Configuration Examples
#### JSON Configuration
```json
{
"agent": {
"my-agent": {
"description": "Custom agent for specific task",
"mode": "subagent",
"model": "anthropic/claude-sonnet-4-20250514",
"temperature": 0.3,
"prompt": "{file:./prompts/my-agent.txt}",
"tools": {
"write": true,
"edit": true,
"bash": false
}
}
}
}
```
#### Markdown Configuration
```markdown
---
description: Custom agent for specific task
mode: subagent
model: anthropic/claude-sonnet-4-20250514
temperature: 0.3
tools:
write: true
edit: true
bash: false
---
You are a specialized agent for...
```
## Agent Permissions
### Permission Levels
- **allow**: Grant unrestricted access
- **ask**: Prompt for confirmation before action
- **deny**: Completely disable the tool
### Example Permissions
```json
{
"permission": {
"bash": {
"git push": "ask",
"git status": "allow",
"*": "deny"
},
"edit": "ask",
"webfetch": "allow"
}
}
```
## Best Practices
### Agent Design
- Keep agents focused on specific tasks
- Use appropriate temperature settings
- Configure minimal necessary permissions
- Write clear, specific prompts
### Security
- Restrict dangerous operations with permissions
- Use `ask` for potentially destructive actions
- Review agent configurations regularly
### Performance
- Use faster models for simple tasks
- Reserve powerful models for complex work
- Consider token usage and costs
