Reports

The solution, it seems, is to add uses:

trigger: none

resources:
  repositories:
    - repository: WikiGit
      type: git
      name: [Project name].wiki

jobs:
  - job:
    uses: # This will not checkout the repo to the agent, but will add the repo to the agent PAT
      repositories:
        - WikiGit
    steps:
      - script: |
          az devops wiki show --wiki "[Project name].wiki" --verbose
          az devops wiki page create --path NewPage --wiki "[Project name].wiki" --comment "added a new page" --content "# New Wiki Page Created!" --verbose
        env:
          AZURE_DEVOPS_EXT_PAT: $(System.AccessToken)
