Simple Agent Example

A minimal agent that greets users and performs text operations.

Code​

from sypho_sdk import entrypoint, tool, AgentContext

@tool
async def reverse_text(text: str):
    """Reverse the given text string"""
    return text[::-1]

@tool
async def count_words(text: str):
    """Count words in the given text"""
    return {"word_count": len(text.split())}

@entrypoint
async def main(input: dict, context: AgentContext):
    """
    You are a text processing assistant.

    You can:
    - Reverse text strings
    - Count words in text

    Always be helpful and respond concisely.
    """
    pass  # LLM handles execution in agent mode

Build and Deploy​

# Initialize project
sypho init greeting-agent
cd greeting-agent

# Add code to src/agent.py (above)

# Build
sypho build --version 0.1.0

# Deploy
sypho deploy --version 0.1.0

Run​

sypho run greeting-agent:0.1.0 \
  --input '{"message": "Reverse this: Hello World"}'

Execution Flow​

  1. User provides input: "Reverse this: Hello World"
  2. LLM analyzes request and available tools
  3. LLM calls reverse_text(text="Hello World")
  4. Tool returns: "dlroW olleH"
  5. LLM responds: "I reversed it: dlroW olleH"
