§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

§5. Error Handling

Common Failure Modes

Failure	Cause	Recovery
API key invalid	Wrong or expired key	Check environment variables
Model rate limit	Too many requests	Add Budget overrun
Tool timeout	Long-running operation	Set timeout: 30s default
Memory overflow	Too many turns	Enable memory compression
MCP connection failed	Network/URL issue	Fallback to local tools

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
