SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill guides users through installing and connecting the A0 CLI on the host machine so a Dockerized Agent Zero can access and operate on real local files, resolving confusion between container and host environments.

Core Features & Use Cases

  • Installer-first guidance for macOS, Linux, and Windows PowerShell with a manual uv tool install fallback when raw installer URLs are unreachable.
  • Host-vs-container checks and explicit instructions to exit container shells, run the connector on the host, and validate connection using the host picker or a custom Agent Zero URL or tunnel.
  • Clear success criteria and troubleshooting steps for connector discovery failures, 404 connector errors, and mismatched Agent Zero builds or missing connector support.

Quick Start

Install the A0 CLI on your host, run a0, and follow the host picker or set AGENT_ZERO_HOST to connect to your Agent Zero instance.

Frequently Asked Questions about a0-setup-cli

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I connect a Dockerized Agent Zero to my local files on the host machine?▼

To connect Agent Zero to local files, install the A0 CLI directly on your host machine, run the a0 command, and use the host picker or set the AGENT_ZERO_HOST environment variable to link your Docker container to local directories.

Can I install the A0 connector on macOS, Linux, and Windows?▼

Yes, the A0 connector supports installation on macOS, Linux, and Windows host environments. It provides installer-first guidance for PowerShell on Windows and manual uv tool install fallbacks if raw installer URLs are unreachable.

Why does my Agent Zero connector discovery fail inside the Docker container?▼

Connector discovery fails when the A0 CLI is mistakenly installed inside the Docker container instead of the host. You must exit the container shell, install and run the connector on the host machine, then validate the connection via the host picker or tunnel URL.

What is the AGENT_ZERO_HOST prefill and how do I use it for local file access?▼

AGENT_ZERO_HOST is an environment variable used to prefill and establish the connection between your host-run A0 connector and the Dockerized Agent Zero instance, ensuring the agent can access and operate on your real local files.

How do I manually install the A0 CLI if the installer URL is unreachable?▼

If the raw installer URL is unreachable, you can manually install the A0 CLI using the uv tool install fallback method on your host machine to ensure the connector is available for Agent Zero.

How do I fix a 404 connector error when linking Agent Zero to local files?▼

A 404 connector error indicates a mismatched Agent Zero build or missing connector support. Verify you are running the a0 command on the host rather than inside the container, and confirm your Agent Zero build supports the host connector feature.
