💡 Example Prompts

Agent Architecture Design

@agentic-orchestration Design an agentic system for:

Task: Automated code review and refactoring
Workflow:
1. Analyze code for issues (complexity, duplication, anti-patterns)
2. Research best practices for identified issues
3. Generate refactoring proposals
4. Validate proposals (syntax, tests)
5. Create pull request with explanations

Decisions needed:
- Single agent vs multiple agents?
- Planning approach (ReAct, Plan-and-Execute, Tree-of-Thought)
- Tools needed (code analysis, test runner, Git)
- Memory requirements (track refactoring history)
- Failure handling (infinite loops, bad refactorings)
- Human-in-the-loop checkpoints

Multi-Agent Coordination

@agentic-orchestration Design a multi-agent system for customer support:

Agents:
1. Triage Agent - Classify issue, determine urgency
2. Research Agent - Search KB, docs, past tickets
3. Resolution Agent - Propose solution
4. QA Agent - Verify solution quality
5. Response Agent - Format customer-friendly response

Coordination:
- Sequential handoffs or parallel execution?
- Consensus mechanism for uncertain cases?
- Escalation path (to human agent)?
- State management across agents?
- Timeout and retry logic?

Provide:
- Agent interaction diagram
- Handoff protocols
- State schema
- Error handling

Planning & Reflection Design

@agentic-orchestration Implement planning with reflection for:

Task: Research competitor analysis
Steps:
1. Plan: Identify key research areas
2. Execute: Gather data from web, reports
3. Reflect: Assess data quality, identify gaps
4. Replan: Adjust strategy based on findings
5. Iterate: Repeat until comprehensive

Requirements:
- Max 5 iterations before forcing conclusion
- Track what worked vs failed (episodic memory)
- Self-critique prompts
- Evidence collection for conclusions
- Confidence scoring

Provide:
- Planning prompt template
- Reflection criteria
- Memory structure
- Termination conditions

Tool Orchestration

@agentic-orchestration Design tool usage for a data analysis agent:

Available tools:
1. query_database(sql: str) -> DataFrame
2. generate_chart(data: DataFrame, chart_type: str) -> Image
3. statistical_test(data: DataFrame, test: str) -> dict
4. summarize_findings(data: dict) -> str
5. search_web(query: str) -> str

Task: Analyze sales data and create executive report

Agent should:
- Plan tool usage sequence
- Handle tool failures (retry, skip, alternate tool)
- Validate tool outputs before next step
- Cache expensive tool calls
- Parallel execution where possible

Provide:
- Tool selection logic
- Error handling for each tool
- Caching strategy
- Dependency graph (which tools depend on others)

---

🎨 Interaction Style

• Planning Before Execution: Think through full task before acting
• Reflection After Action: Critique results, identify improvements
• Tool-Conscious: Only call tools when necessary, validate outputs
• Memory-Aware: Track what’s been tried, learn from failures
• Human-in-the-Loop: Checkpoints for critical decisions
• Graceful Degradation: Partial success better than failure

---

📐 Decision Framework

Single Agent vs Multi-Agent

Question: One agent or multiple agents?

Single Agent:
✅ Simpler architecture
✅ Lower latency (no handoffs)
✅ Easier to debug
❌ Limited by single context window
❌ No specialization

Use when:
- Task fits in one context window
- <5 tools needed
- No clear sub-task boundaries

Multi-Agent:
✅ Specialization (expert agents)
✅ Parallel execution possible
✅ Scales to complex tasks
❌ Handoff overhead
❌ Harder to debug

Use when:
- Clear sub-tasks (research, write, review)
- >5 tools (group by agent)
- Parallel work possible
- Task too large for one context

Planning Pattern Selection

Question: Which planning approach?

ReAct (Thought-Action-Observation):
✅ Simple, works for many tasks
✅ Handles dynamic situations
❌ Can get stuck in loops
❌ No global planning

Use for: Customer support, data analysis, web research

Plan-and-Execute:
✅ Upfront planning, then execution
✅ Predictable, efficient
❌ Can't adapt mid-execution
❌ Requires clear task definition

Use for: Report generation, data pipelines, structured workflows

Tree-of-Thought:
✅ Explores multiple reasoning paths
✅ Finds non-obvious solutions
❌ Expensive (multiple LLM calls)
❌ Slow

Use for: Complex problem solving, math, puzzles

Reflexion:
✅ Learns from mistakes
✅ Iteratively improves
❌ Multiple iterations needed
❌ High cost

Use for: Code generation, creative writing, research

Memory Design

Question: What type of memory?

Conversation Memory:
- Scope: Current session
- Implementation: Sliding window, summarization
- Use: Chatbots, customer support

Task Memory:
- Scope: Current task execution
- Implementation: Key-value store, task state
- Use: Multi-step workflows, agents

Episodic Memory:
- Scope: Past conversations/tasks
- Implementation: Vector DB, semantic search
- Use: Learning from past, personalization

Semantic Memory:
- Scope: Facts, entities, relationships
- Implementation: Knowledge graph, triple store
- Use: Question answering, reasoning

Recommendation:
- Start with conversation + task memory
- Add episodic for learning
- Add semantic for knowledge-intensive tasks

🛠️ Common Patterns

Pattern 1: ReAct Agent Loop

from typing import List, Dict, Any

def react_agent(
    task: str,
    tools: List[Callable],
    max_iterations: int = 10
) -> str:
    """
    ReAct: Thought → Action → Observation loop.
    """
    conversation = [
        {"role": "system", "content": REACT_SYSTEM_PROMPT},
        {"role": "user", "content": f"Task: {task}"}
    ]
    
    for iteration in range(max_iterations):
        # Generate thought and action
        response = llm.chat(conversation)
        
        # Parse response
        thought = extract_thought(response)
        action = extract_action(response)
        
        if action["type"] == "finish":
            return action["answer"]
        
        # Execute action (tool call)
        tool_result = execute_tool(action["tool"], action["args"], tools)
        
        # Add observation to conversation
        observation = f"Observation: {tool_result}"
        conversation.append({"role": "assistant", "content": response})
        conversation.append({"role": "user", "content": observation})
    
    return "Max iterations reached without conclusion"

# ReAct system prompt
REACT_SYSTEM_PROMPT = """
You are a problem-solving agent. For each step:

1. **Thought**: Reason about what to do next
2. **Action**: Call a tool or finish
3. **Observation**: Receive tool result

Format:
Thought: [your reasoning]
Action: [tool_name(arg1="value1", arg2="value2")]
... wait for observation ...

Available tools:
- search(query: str) -> str
- calculate(expression: str) -> float
- finish(answer: str) -> None

Example:
Thought: I need to find the population of France.
Action: search(query="population of France")
Observation: The population of France is 67 million.
Thought: I have the answer.
Action: finish(answer="67 million")

        Previous results: {context}
        
        Call the appropriate tool with the correct arguments.
        """
        
        tool_call = llm.generate_function_call(execution_prompt, tools)
        result = execute_tool(tool_call["name"], tool_call["args"], tools)
        
        execution_result = ExecutionResult(

📊 Metrics I Care About

• Task Success Rate: % of tasks completed successfully
• Planning Accuracy: % of plans executed without replanning
• Tool Call Accuracy: % of tool calls with valid results
• Iteration Count: Average iterations to completion
• Cost per Task: Total LLM cost per task
• Latency: Time from task start to completion
• Human Intervention Rate: % of tasks requiring human input
