GitLab

Use ReignCode in GitLab issues and merge requests.

ReignCode integrates with your GitLab workflow through your GitLab CI/CD pipeline or with GitLab Duo.

In both cases, ReignCode will run on your GitLab runners.

GitLab CI

ReignCode works in a regular GitLab pipeline. You can build it into a pipeline as a CI component

Here we are using a community-created CI/CD component for ReignCode — nagyv/gitlab-reigncode.

Features

Use custom configuration per job: Configure ReignCode with a custom configuration directory, for example ./config/#custom-directory to enable or disable functionality per ReignCode invocation.
Minimal setup: The CI component sets up ReignCode in the background, you only need to create the ReignCode configuration and the initial prompt.
Flexible: The CI component supports several inputs for customizing its behavior

Setup

Store your ReignCode authentication JSON as a File type CI environment variables under Settings > CI/CD > Variables. Make sure to mark them as “Masked and hidden”.

Add the following to your .gitlab-ci.yml file.

include:
  - component: $CI_SERVER_FQDN/nagyv/gitlab-reigncode/reigncode@2
    inputs:
      config_dir: ${CI_PROJECT_DIR}/reigncode-config
      auth_json: $REIGNCODE_AUTH_JSON # The variable name for your ReignCode authentication JSON
      command: optional-custom-command
      message: "Your prompt here"

For more inputs and use cases check out the docs for this component.

GitLab Duo

ReignCode integrates with your GitLab workflow. Mention @reigncode in a comment, and ReignCode will execute tasks within your GitLab CI pipeline.

Features

Triage issues: Ask ReignCode to look into an issue and explain it to you.
Fix and implement: Ask ReignCode to fix an issue or implement a feature. It will create a new branch and raise a merge request with the changes.
Secure: ReignCode runs on your GitLab runners.

Setup

ReignCode runs in your GitLab CI/CD pipeline, here’s what you’ll need to set it up:

Configure your GitLab environment
Set up CI/CD
Get an AI model provider API key
Create a service account
Configure CI/CD variables

Create a flow config file, here’s an example:

Flow configuration

  - echo "Installing reigncode"
  - npm install --global reigncode-ai

    You are an AI assistant helping with GitLab operations.

    Context: $AI_FLOW_CONTEXT
    Task: $AI_FLOW_INPUT
    Event: $AI_FLOW_EVENT

    Please execute the requested task using the available GitLab tools.
    Be thorough in your analysis and provide clear explanations.

    <important>
    Please use the glab CLI to access data from GitLab. The glab CLI has already been authenticated. You can run the corresponding commands.

    If you are asked to summarize an MR or issue or asked to provide more information then please post back a note to the MR/Issue so that the user can see it.
    You don't need to commit or push up changes, those will be done automatically based on the file changes you make.
