# Airbnb — Airchat (airchat-cli)

Airchat is Airbnb's internal agentic-coding harness, built by its Dev AI team as a wrapper over vendor coding agents such as Claude Code. The team first built its own orchestrator from scratch, never shipped it, and delegated to Airchat with a thin shim instead.

## Overview

### Summary

Airchat is Airbnb's internal agentic-coding harness, built by its Dev AI team as a wrapper over vendor coding agents such as Claude Code. The team first built its own orchestrator from scratch, never shipped it, and delegated to Airchat with a thin shim instead.

Fact · Reported · Medium confidence · `airbnb-airchat--summary`

Confidence reason: The build is described by Airbnb engineers in talks and podcasts, not in a first-party engineering blog.

## Supervision evidence

### Operating model assessment

Level 3 for coding task → reviewed pull request; human attention boundary: work-product-review.

Inference · Catalog judgment · Medium confidence · `airbnb-airchat--operating-models-0`

Confidence reason: Airbnb engineers describe agents producing pull requests that engineers review, which locates human attention at work-product review.
