Get a Loom agent running in under 5 minutes.

import asyncio

from loom import Agent, Model, Runtime


async def main():
    agent = Agent(
        model=Model.anthropic("claude-sonnet-4"),
        instructions="You are a concise assistant.",
        runtime=Runtime.sdk(),
    )

    result = await agent.run("List the main capabilities of Loom")
    print(result.output)


asyncio.run(main())

1. Agent is the only top-level execution object.
2. Model selects the provider-backed model.
3. Runtime selects the execution profile and policy composition.
4. Capability declares files, web, shell, MCP, and skill access.
5. Use agent.run() for one-off executions.
6. Use agent.session(SessionConfig(...)) when the application needs continuity.
7. Use RuntimeSignal and SignalAdapter for gateway, cron, heartbeat, webhook, and application events.

• Start from from loom import ... for the main application path.
• Use from loom.config import ... for advanced configuration internals.
• Use from loom.runtime import ... only when you need runtime states or mechanism contracts directly.

Use Model to select a provider-backed model:

• Model.anthropic(...)
• Model.openai(...)
• Model.gemini(...)
• Model.qwen(...)
• Model.ollama(...)

Provider implementations live under loom/providers/, but application code should normally configure providers through Model.
