Fabric是一个开源的AI增强框架，旨在解决AI提示词泛滥和难以管理的问题
Fabric相信AI不是目的，而是帮助人类实现创造力的工具
package main
import (
"github.com/danielmiessler/fabric/internal/core"
"github.com/danielmiessler/fabric/internal/cli"
"github.com/danielmiessler/fabric/internal/server"
)
func main() {
// Fabric采用分层架构设计
// 核心组件: chatter, plugin_registry
// CLI接口: 命令行处理
// REST服务: HTTP API服务器
fabric := core.NewFabric()
cli.Run(fabric)
server.Start(fabric)
}Fabric采用Go语言构建，采用清晰的分层架构
Fabric采用分层架构，核心逻辑与接口分离
Fabric从Python迁移到Go，获得了显著的性能提升
type Chatter struct {
providers map[string]Provider
patterns map[string]*Pattern
contexts map[string]*Context
sessions map[string]*Session
strategies map[string]*Strategy
}
func (c *Chatter) Chat(input string, pattern string, opts *ChatOptions) (*ChatResponse, error) {
// 1. 查找对应的pattern
pattern := c.patterns[pattern]
if pattern == nil {
return nil, fmt.Errorf("pattern not found")
}
// 2. 应用prompt strategy
prompt := c.applyStrategy(pattern.System, opts.Strategy)
// 3. 调用AI provider
provider := c.providers[opts.Vendor]
return provider.Generate(prompt, input, opts)
}Chatter是Fabric的核心聊天组件，负责整个AI交互流程
Patterns是Fabric的核心创新，将AI提示词结构化、可管理化
# Summarize Pattern
## System
You are an expert summarizer. Create concise, comprehensive summaries of text content.
## Instructions
1. Read the input text carefully
2. Identify key themes and main points
3. Extract the most important information
4. Create a structured summary with clear sections
5. Maintain the original tone and perspective
6. Preserve technical accuracy and important details
## Format
- Use clear headings and bullet points
- Include key statistics when present
- Maintain original author's voice
- Keep the summary to 1/3 of original length
- Include any specific technical terminology
## Output Structure
### Main Summary
[2-3 sentences capturing essence]
### Key Points
- [Bullet point 1]
- [Bullet point 2]
- [Bullet point 3]
### Technical Details
[Relevant technical information]每个Pattern都采用Markdown格式，确保可读性和AI可理解性
Fabric支持主流AI供应商，提供统一的接口层
Provider抽象层支持原生和兼容两种模式
Fabric实现多种先进提示策略，提升AI推理质量

"name": "cot",
"description": "Chain-of-Thought: Step-by-step reasoning",
"template": "Let's think step by step about this problem.\n\n{{content}}\n\nPlease provide a detailed step-by-step analysis that:\n1. Breaks down the problem into manageable parts\n2. Solves each part systematically\n3. Shows your reasoning process clearly\n4. Arrives at a well-supported conclusion"
}Chain of Thought策略引导AI进行逐步推理
Fabric提供完整的REST API，便于集成和扩展
// POST /api/chat
func (s *Server) handleChat(w http.ResponseWriter, r *http.Request) {
var req ChatRequest
if err := json.NewDecoder(r.Body).Decode(&req); err != nil {
http.Error(w, err.Error(), http.StatusBadRequest)
return
}
// 验证输入
if req.Pattern == "" || req.Input == "" {
http.Error(w, "pattern and input required", http.StatusBadRequest)
return
}
// 处理AI请求
response, err := s.fabric.Chat(req.Input, req.Pattern, &req.Options)
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
// 流式返回结果
s.streamResponse(w, response)
}API支持流式响应，提供更好的用户体验
Fabric可以替代Ollama，支持现有工具无缝迁移
