+## A2A (Agent2Agent Protocol)
+
+PraisonAI supports the [A2A Protocol](https://a2a-protocol.org) for agent-to-agent communication, enabling your agents to be discovered and collaborate with other AI agents.
+
+### A2A Server (Expose Agent as A2A Server)
+```python
+from praisonaiagents import Agent, A2A
+from fastapi import FastAPI
+
+# Create an agent with tools
+def search_web(query: str) -> str:
+    """Search the web for information."""
+    return f"Results for: {query}"
+
+agent = Agent(
+    name="Research Assistant",
+    role="Research Analyst",
+    goal="Help users research topics",
+    tools=[search_web]

+
+# Expose as A2A Server
+a2a = A2A(agent=agent, url="http://localhost:8000/a2a")

+app.include_router(a2a.get_router())
+
+# Run: uvicorn app:app --reload
+# Agent Card: GET /.well-known/agent.json
+# Status: GET /status
+```
+
+### A2A Features
+| Feature | Description |
+|---------|-------------|

+| Skills Extraction | Auto-generate skills from tools |
+| Task Management | Stateful task lifecycle |

+PraisonAI Agents - Comprehensive Performance Benchmark
+======================================================================
+
+This benchmark measures:
+  1. Agent instantiation time (how fast an agent object is created)
+  2. Memory footprint (how much memory an agent uses)
+
+Methodology:
+  - 10 warmup runs (not measured)
+  - 1000 measured iterations
+  - tracemalloc for memory measurement
+  - Baseline subtraction for accuracy
+
+Frameworks available:
+  - PraisonAI: ✅
+  - Agno: ✅
+  - PydanticAI: ✅
+  - OpenAI Agents SDK: ✅
+  - LangGraph: ✅
+  - CrewAI: ✅

+## A2A (Agent2Agent Protocol)
+
+PraisonAI supports the [A2A Protocol](https://a2a-protocol.org) for agent-to-agent communication, enabling your agents to be discovered and collaborate with other AI agents.
+
+### A2A Server (Expose Agent as A2A Server)
+```python
+from praisonaiagents import Agent, A2A
+from fastapi import FastAPI
+
+# Create an agent with tools
+def search_web(query: str) -> str:
+    """Search the web for information."""
+    return f"Results for: {query}"
+
+agent = Agent(
+    name="Research Assistant",
+    role="Research Analyst",
+    goal="Help users research topics",
+    tools=[search_web]
+)
+
+# Expose as A2A Server
+a2a = A2A(agent=agent, url="http://localhost:8000/a2a")
+
+app = FastAPI()
+app.include_router(a2a.get_router())
+
+# Run: uvicorn app:app --reload
+# Agent Card: GET /.well-known/agent.json
+# Status: GET /status
+```
+
+### A2A Features
+| Feature | Description |

+| Skills Extraction | Auto-generate skills from tools |
+| Task Management | Stateful task lifecycle |
+| Streaming | SSE streaming for real-time updates |

+First, analyze the task complexity:
+- Is this a simple task that 1-2 agents could handle?
+- Does it require multiple specialized perspectives?
+- Are there clear sequential dependencies between steps?
+
+STEP 2: DETERMINE OPTIMAL TEAM SIZE
+Based on your analysis, create the minimum number of agents needed:
+- Simple tasks: 1-2 agents
+- Moderate tasks: 2-3 agents  
+- Complex tasks: 3-4 agents (maximum)
+
+IMPORTANT: Only create agents that provide meaningful specialization. Avoid unnecessary complexity.
+
+STEP 3: DESIGN THE TEAM (Pattern: {self.pattern})

+- A clear, distinct role
+- A specific goal
+- Relevant backstory
+- 1 focused task with clear description and expected output
+- Appropriate tools (only if needed)
