Self-evolving tool synthesis for Strands Agents — agents that create their own tools

strands-arise

Self-evolving tool synthesis for Strands Agents. Agents that create their own tools.

pip install strands-arise

from strands import Agent
from strands_arise import ARISEPlugin

agent = Agent(
    model=my_model,
    plugins=[ARISEPlugin(
        failure_threshold=3,
        allowed_imports=["json", "re", "hashlib", "csv", "math"],
    )],
)

# Agent evolves tools automatically from failures
result = agent("Parse the CSV with custom delimiters")

How It Works

1. Agent attempts a task and fails
2. ARISE detects the capability gap from failure trajectories
3. An LLM synthesizes a Python tool + test suite
4. Tool is validated in a sandbox with adversarial testing
5. Passing tools are promoted to the agent's tool registry
6. Next invocation, the agent has the new tool available
