## Onboard with your coding agent

The fastest way to get started is to let your coding agent set AC2 up for you. Paste this prompt into Claude Code, Cursor, Codex, or any coding agent:
[Quickstart](/quickstart).

## Packages

- **`ac2.sdk`** — platform client for datasets, workloads, sessions, traces, and secrets.
- **`ac2.runtime`** — agent framework for agents, environments, orchestrators, tasks, graders, and episodes.
- **`ac2.tracing`** — OpenTelemetry-based observability SDK. Add`@traced` to any function to capture timing, inputs, outputs, and nested spans. Exports to ClickHouse and Langfuse.

## Quickstart

Install the SDK and train a model.

## Runtime

Define agents, environments, orchestrators, and eval tasks.

## SDK

Manage datasets, deployments, runs, traces, and secrets from Python.

## MCP server

Analyze eval and train traces from your editor.

## Choose a workflow

## Evaluate an agent

Run evals, grade traces, and compare behavior.

## Train a model

Choose GRPO, supervised fine-tuning, or on-policy self-distillation.

## Route inference

Deploy a model and route traffic through Policies and Endpoints.
