Decision Framework

When to use each component:

§1.3 Thinking

Constraint Stack

1. Security First: Validate all tool inputs, never expose API keys in logs
2. Production-Ready: Include error handling, logging, monitoring (OTel)
3. Scalability: Design for multi-agent from start, use MsgHub
4. Memory Management: Choose appropriate memory based on conversation length
5. Performance: Use streaming for better UX, async/await for concurrency

Quality Standards

• Response Time: < 3s for agent response (excluding tool calls)
• Tool Reliability: Vendor non-performance for failing tools (3 failures → 60s cooldown)
• Memory Efficiency: Compress memory every 50 turns
• Error Recovery: Compliance violation with fallback responses

§2. Triggers

CREATE Triggers:

• "build agent with AgentScope"
• "create voice agent"
• "setup multi-agent workflow"
• "add memory to agent"
• "integrate MCP tools"
• "fine-tune agent model"

EVALUATE Triggers:

• "evaluate agent performance"
• "test AgentScope setup"
• "benchmark agent response time"
• "assess memory efficiency"

§3. Workflow

Phase 1: Environment Setup

Done: Python 3.10+ installed, AgentScope installed Fail: Python < 3.10, missing dependencies

# Installation
pip install agentscope
# Or with uv
uv pip install agentscope

# From source
git clone -b main https://github.com/agentscope-ai/agentscope.git
cd agentscope
pip install -e .

Phase 2: Agent Design

Done: Agent architecture defined (ReAct/Voice/Multi-agent) Fail: No clear use case or agent type

Design Checklist:

• Single or multi-agent?
• Voice enabled?
• Memory needed? (short-term / long-term / ReMe)
• External tools? (MCP / A2A / native)
• Deployment target? (local / serverless / K8s)

Phase 3: Implementation

Done: Working agent with basic functionality Fail: Agent cannot respond to user input

Implementation Steps:

1. Import required modules
2. Initialize model (DashScope/OpenAI/Anthropic)
3. Create toolkit with tools
4. Instantiate agent with memory and formatter
5. Add user interaction loop

Phase 4: Advanced Features

Done: Memory, tools, multi-agent configured Fail: Missing required features

Advanced Options:

• Memory: InMemoryMemory, SqliteMemory, ReMe
• Tools: execute_python_code, execute_shell_command, MCP tools
• Multi-agent: MsgHub, sequential_pipeline, concurrent_pipeline
• Voice: TTS, STT integration

Phase 5: Testing & Optimization

Done: Agent passes functional tests Fail: Tests fail or performance issues

Test Coverage:

• Basic conversation flow
• Tool execution
• Memory persistence (if applicable)
• Error handling
• Response time < 3s

Phase 6: Deployment

Done: Agent deployed and accessible Fail: Deployment fails or unreachable

Deployment Options:

• Local: python app.py
• Serverless: AgentScope Runtime
• K8s: With OTel monitoring

        model=DashScopeChatModel(
            model_name="qwen-max",
            api_key=os.environ["DASHSCOPE_API_KEY"],

§5. Error Handling

Common Failure Modes

Recovery Strategies

# Retry with Budget overrun
from agentscope.tools import retry_with_backoff

@retry_with_backoff(max_retries=3, initial_delay=1.0)
async def call_model_with_retry(agent, msg):
    return await agent(msg)

# Vendor non-performance for tools
from agentscope.tools import CircuitBreaker

breaker = CircuitBreaker(failure_threshold=3, recovery_timeout=60)

# Compliance violation
try:
    result = await agent(msg)
except Exception as e:
    result = "I'm having trouble processing your request. Please try again."

§6. Security

Red Lines

• ❌ Never hardcode API keys in source code
• ❌ Never expose sensitive data in agent responses
• ❌ Never skip input validation for tools
• ❌ Never disable logging in production

Best Practices

• ✅ Use environment variables: os.environ["DASHSCOPE_API_KEY"]
• ✅ Validate tool inputs before execution
• ✅ Log with OTel for production monitoring
• ✅ Implement rate limiting for agent access
