Agent Skills: Azure Pipelines Tasks Source Code

Azure Pipelines Tasks Source Code

The source code for Azure DevOps built-in pipeline tasks lives in microsoft/azure-pipelines-tasks.

Finding Task Source Code

Tasks are in Tasks/<TaskName>V<Version>/ directories. The naming convention is:

• Tasks/AzureCLIV2/ → AzureCLI@2
• Tasks/DotNetCoreCLIV2/ → DotNetCoreCLI@2
• Tasks/PublishBuildArtifactsV1/ → PublishBuildArtifacts@1

Key Files in Each Task

| File | Purpose | |------|---------| | task.json | Task definition: inputs, outputs, execution entry point | | *.ts or *.ps1 | Main implementation (check task.json for entry point) | | Strings/resources.resjson/en-US/resources.resjson | User-facing strings and error messages | | Tests/ | Unit tests showing expected behavior |

Workflow

1. Identify the task name and version from the pipeline YAML (e.g., AzureCLI@2)
2. Search the repo for the task directory:

   gh api repos/microsoft/azure-pipelines-tasks/contents/Tasks/<TaskName>V<Version>
   

3. Read task.json to find the execution entry point
4. Read the implementation file to understand behavior

Example: Finding AzureCLI@2 Implementation

# Get task definition
gh api repos/microsoft/azure-pipelines-tasks/contents/Tasks/AzureCLIV2/task.json

# Get main implementation
gh api repos/microsoft/azure-pipelines-tasks/contents/Tasks/AzureCLIV2/azureclitask.ts

Searching for Specific Behavior

Use GitHub code search to find where specific logic is implemented:

repo:microsoft/azure-pipelines-tasks path:Tasks/<TaskName> <search_term>
