高级开发指南
本指南提供了使用 agent_skills 协议开发技能系统的详细说明和最佳实践。
agent_skills 应用架构
典型架构组件
agent_skills 应用通常包含以下核心组件:
- 技能提供者:负责技能的注册、管理和执行
- 技能注册中心:提供技能的注册、发现和索引服务
- 技能客户端:处理技能的调用和结果处理
- 工作流引擎:执行技能组合工作流
- 安全层:处理授权和认证
- 监控系统:跟踪系统性能和健康状况

开发技能的步骤
1. 规划技能功能
确定你的技能将提供哪些功能:
- 技能的专业领域是什么?
- 它应该能处理哪些类型的输入?
- 它需要返回什么类型的输出?
- 它需要与哪些其他技能协作?
2. 设计技能接口
定义技能的输入和输出:
from typing import TypedDict
class SentimentAnalysisInput(TypedDict):
text: str
language: str
class SentimentAnalysisOutput(TypedDict):
sentiment: str # "positive", "negative", "neutral"
confidence: float
probabilities: dict[str, float]
def analyze_sentiment(input_data: SentimentAnalysisInput) -> SentimentAnalysisOutput:
"""分析文本情感"""
# 实现逻辑
pass
3. 实现处理逻辑
from agent_skills import SkillProvider
class SentimentAnalysisSkill:
def __init__(self):
self.model = self.load_model()
def load_model(self):
# 加载情感分析模型
pass
def process(self, text: str, language: str) -> dict:
# 1. 验证输入
if not text or len(text.strip()) == 0:
raise ValueError("文本不能为空")
# 2. 预处理文本
processed_text = self.preprocess(text, language)
# 3. 执行情感分析
result = self.model.predict(processed_text)
# 4. 构建输出
return {
"sentiment": result.sentiment,
"confidence": result.confidence,
"probabilities": result.probabilities
}
# 注册技能
provider = SkillProvider(agent_id="nlp-expert-agent")
skill = SentimentAnalysisSkill()
provider.register_skill({
"skill_id": "text-sentiment-analysis",
"name": "文本情感分析",
"handler": skill.process,
"version": "1.0.0"
})
4. 添加错误处理
def process_with_error_handling(self, text: str, language: str) -> dict:
try:
# 验证输入
if not isinstance(text, str):
raise TypeError("text 必须是字符串类型")
if not text.strip():
raise ValueError("text 不能为空")
# 处理任务
result = self.analyze(text, language)
return {
"success": True,
"result": result
}
except ValueError as e:
return {
"success": False,
"error": {
"code": "INVALID_INPUT",
"message": str(e)
}
}
except Exception as e:
return {
"success": False,
"error": {
"code": "INTERNAL_ERROR",
"message": "处理过程中发生错误"
}
}
5. 实现技能协作
from agent_skills import SkillClient, SkillWorkflow
class MultiSkillProcessor:
def __init__(self, client: SkillClient):
self.client = client
async def process_text_pipeline(self, text: str):
# 1. 预处理文本
preprocessed = await self.client.call_skill_async(
skill_id="text-preprocessing",
provider_agent_id="text-processor-agent",
parameters={"text": text}
)
# 2. 情感分析
sentiment = await self.client.call_skill_async(
skill_id="text-sentiment-analysis",
provider_agent_id="nlp-expert-agent",
parameters={"text": preprocessed["processed_text"]}
)
# 3. 生成摘要
summary = await self.client.call_skill_async(
skill_id="generate-summary",
provider_agent_id="summary-agent",
parameters={
"text": preprocessed["processed_text"],
"sentiment": sentiment["sentiment"]
}
)
return {
"original_text": text,
"preprocessed": preprocessed,
"sentiment": sentiment,
"summary": summary
}
高级开发技术
1. 技能缓存
实现技能结果缓存以提高性能:
from functools import lru_cache
import hashlib
import json
class CachedSkill:
def __init__(self, cache_ttl=3600):
self.cache = {}
self.cache_ttl = cache_ttl
def _generate_cache_key(self, skill_id: str, parameters: dict) -> str:
"""生成缓存键"""
key_data = {
"skill_id": skill_id,
"parameters": parameters
}
key_str = json.dumps(key_data, sort_keys=True)
return hashlib.md5(key_str.encode()).hexdigest()
def call_skill_cached(self, skill_id: str, parameters: dict):
"""带缓存的技能调用"""
cache_key = self._generate_cache_key(skill_id, parameters)
# 检查缓存
if cache_key in self.cache:
cached_result, timestamp = self.cache[cache_key]
if time.time() - timestamp < self.cache_ttl:
return cached_result
# 调用技能
result = self.client.call_skill(skill_id, parameters)
# 更新缓存
self.cache[cache_key] = (result, time.time())
return result
