  aiSlashCommands(
    url: "<ANY URL>",
  ) {
    name

    command  
  }
}

Special commands

The following are all special commands, which require Duo Enterprise enabled for the group of the URL that is passed in.

Vulnerabilities

Prerequisites:

• Vulnerability must be of sast type to receive the /vulnerability_explain command

Steps:

1. Create vulnerability via UI:

   • Navigate to Secure -> Vulnerability report -> Submit vulnerability
   • Required fields:
     • Identifier code: e.g. "1228"
     • URL: e.g. "https://cwe.mitre.org/data/definitions/1228.html"

2. Update type in rails console:

# Convert to sast type
Vulnerability.last.update!(report_type: :sast)

3. Test slash command availability:

query {
  aiSlashCommands(
    userId: "gid://gitlab/User/1"
  ) {
    name
    description
    command  
  }
}

Jobs

Prerequisites:

• Job must be in failed state to receive /troubleshoot command
• The easiest way to do this might be to go your Duo Enterprise group, click Builds -> Jobs on the sidebar, Create CI/CD configuration file, Commit changes, and then update the last job to be failed manually in the rails console.

 Ci::Build.last.update!(status: :failed)

query {
  aiSlashCommands(
    url: "<JOB URL>", 
  ) {
    name
    description
    command
  }
}

Issues

query {
  aiSlashCommands(
    url: "<ISSUE URL>",
  ) {
    name
    description
    command
  }
}
