error_handling.tmpl # Error handling practices +└── best_practices.tmpl # Comprehensive best practices +``` + +#### Template Variables +Instructions templates have access to rich template data: + +```go +type InstructionTemplateData struct { + BaseURL string // Server base URL + ServerName string // Server name + ServerVersion string // Server version + AvailableTools []string // List of available tools + CustomData map[string]interface{} // Custom template data +} +``` + +#### Creating Custom Instruction Templates +```markdown +# {{.ServerName}} Instructions + +## Server Information +- **Name**: {{.ServerName}} +- **Version**: {{.ServerVersion}} +- **Base URL**: {{.BaseURL}} + +## Available Tools +{{range .AvailableTools}} +- {{.}} +{{end}} + +## Custom Configuration +{{if .CustomData.rate_limits}} +### Rate Limits +- Requests per minute: {{.CustomData.rate_limits.requests_per_minute}} +- Concurrent requests: {{.CustomData.rate_limits.concurrent_requests}} +{{end}} +``` + +## Usage Examples +Connect to this server using your preferred MCP client: + +```bash +mcp-client connect {{.BaseURL}} +``` + +### Using the Instruction System + +#### Direct Instruction Generation +```go +// Generate instructions using the global system +templateData := mcp.InstructionTemplateData{ + BaseURL: "https://api.example.com", + ServerName: "my-server", + ServerVersion: "1.0.0", + AvailableTools: []string{"chat_completions", "embeddings"}, + CustomData: map[string]interface{}{ + "features": []string{"streaming", "batch"}, + }, +} + +instructions := mcp.GenerateInstructions(mcp.GeneralInstructions, templateData) +``` + +#### Custom Instruction Renderer +```go +// Create custom renderer for advanced use cases +renderer, err := mcp.NewInstructionRenderer() +if err != nil { + log.Fatal(err) +} + +// Check available instruction types +types := renderer.GetAvailableInstructionTypes() +fmt.Printf("Available instruction types: %v\n", types) + +// Generate specific instructions +instructions, err := renderer.GenerateInstructions( + mcp.ToolUsageInstructions, + templateData, +) +if err != nil { + log.Printf("Failed to generate instructions: %v", err) +} +``` + +### MCP Tools Integration + +The instruction system automatically registers an `instructions` tool when enabled: + +```go +// The instructions tool is available to MCP clients +// Usage example from MCP client: +{ + "tool": "instructions", + "arguments": { + "type": "general", // Optional: instruction type + "include_tools": true, // Optional: include tool list + "custom_data": { // Optional: additional context + "user_level": "beginner" + } + } +} +``` + +### Migration Guide + +#### Existing Code (No Changes Required) +```go +// Existing code continues to work unchanged +server := mcp.NewServer() +``` + +#### Enhanced with Instructions +```go +// Enhanced version with instruction support +opts := mcp.DefaultServerOptions(). + WithInstructionType(mcp.GeneralInstructions) + +server := mcp.NewServerWithOptions(opts) +``` + +### Adding New Instruction Types + +#### Step 1: Define the Instruction Type +```go +const ( + // Add to existing instruction types + CustomInstructionType InstructionType = "custom_instruction" +) +``` + +#### Step 2: Update the Registry +```go +func (r *InstructionRenderer) initializeInstructionRegistry() { + r.registry = map[InstructionType]string{ + // ... existing mappings + CustomInstructionType: "custom_instruction", + } +} +``` + +#### Step 3: Create Template File +Create `docs/templates/instructions/custom_instruction.tmpl`: + +```markdown +# Custom Instructions for {{.ServerName}} + +## Overview +Custom instruction content here... + +## Server Details +- Base URL: {{.BaseURL}} +- Version: {{.ServerVersion}} + +## Available Tools +{{range .AvailableTools}} +- **{{.}}**: Tool description +{{end}} +``` + +#### Step 4: Use the New Type +```go +opts := mcp.DefaultServerOptions(). + WithInstructionType(CustomInstructionType) + +server := mcp.NewServerWithOptions(opts) +``` + +### Best Practices for Instructions + +#### Template Design +1. **Clear Structure**: Use consistent sections and formatting +2. **Actionable Content**: Provide specific, actionable guidance +3. **Context Awareness**: Use template data to customize content +4. **Progressive Disclosure**: Start with basics, provide advanced details + +#### Server Configuration +1. **Choose Appropriate Type**: Select instruction type that matches your use case +2. **Provide Custom Data**: Enhance templates with server-specific information +3. **Test Instructions**: Verify instruction generation in different scenarios +4. **Update Documentation**: Keep instruction templates current with server changes + +### Performance Considerations + +- **Template Caching**: Instructions templates are cached for performance +- **Lazy Loading**: Templates loaded only when instruction system is enabled +- **Minimal Overhead**: Instruction system adds minimal performance impact +- **Fallback Efficiency**: Fallback generation is optimized for speed + +### Testing Instructions + +```go +func TestCustomInstructions(t *testing.T) { + opts := mcp.DefaultServerOptions(). + WithName("test-server"). + WithInstructionType(mcp.GeneralInstructions). + WithCustomTemplateData("test_mode", true) + + server := mcp.NewServerWithOptions(opts) + + // Test that instructions are enabled + assert.True(t, server.GetOptions().EnableInstructions) + + // Test instruction generation + tools := server.GetAvailableToolNames() + assert.Contains(t, tools, "instructions") +} +``` + +### Troubleshooting Instructions + +#### Common Issues +1. **Instructions Not Available**: Check that `EnableInstructions` is true in server options +2. **Template Errors**: Verify template syntax and variable names +3. **Missing Tools**: Ensure instruction tool is registered in handlers +4. **Fallback Behavior**: System falls back to generic instructions if templates fail + +#### Debug Tips +1. **Check Server Options**: Verify instruction configuration in server options +2. **Validate Templates**: Use test suite to validate instruction templates +3. **Test Tool Registration**: Confirm instructions tool appears in available tools list +4. **Monitor Fallbacks**: Check logs for template loading errors + +The instruction system provides a powerful way to enhance user experience by providing contextual, server-specific guidance while maintaining the same level of reliability and performance as the core documentation system. + +## Deployment Architecture + +### Integration with One-API Repository + +This MCP server is designed to integrate seamlessly with the
