glab duo

Overview

 
  Work with GitLab Duo, our AI-native assistant for the command line.
 
  The GitLab Duo CLI integrates AI capabilities directly into your terminal
  workflow. It helps you retrieve forgotten Git commands and offers guidance on
  Git operations. You can accomplish specific tasks without switching contexts.
 
  To interact with the GitLab Duo Agent Platform, use the
  [GitLab Duo CLI](https://docs.gitlab.com/user/gitlab_duo_cli/).
 
  A unified experience is proposed in
  [epic 20826](https://gitlab.com/groups/gitlab-org/-/work_items/20826).
 
  USAGE
 
    glab duo <command> prompt [command] [--flags]
 
  COMMANDS

    cli [command]           Run the GitLab Duo CLI (EXPERIMENTAL)
 
  FLAGS

Quick start

glab duo --help

Command surface guidance

Upstream glab now hides and deprecates glab duo ask.

Treat glab duo ask as legacy guidance only for older installed versions that still expose it in live help. For current forward-looking documentation, prefer:

glab duo cli

Use glab duo cli when you specifically want the experimental GitLab Duo CLI surface that glab now exposes.

Installing GitLab Duo CLI

glab duo cli supports --install and --yes flags:

# Install GitLab Duo CLI interactively
glab duo cli --install
 
# Install GitLab Duo CLI non-interactively (auto-confirm)
glab duo cli --install --yes

Use --install to download and install the GitLab Duo CLI binaries. Use --yes to skip confirmation prompts during installation, which is useful for automation and CI/CD pipelines.

Important documentation note

Guidance that recommends glab duo update is stale; rely on live help before using any Duo subcommand that is not documented here.

When local CLI help and external documentation diverge during a transition, document the current upstream direction clearly and note compatibility caveats only when they materially affect usage.

Subcommands
