Autofix CI failures

Use Trunk and AI agents to automatically fix CI failures

Trunk can return targeted information about CI failures, enabling AI agents and automation tools to analyze and fix issues automatically.

Prerequisites

To use the Autofix CI Failures feature, you’ll need to have:

• Your repository set up to upload test results to Trunk

Cursor CI Autofix

You can set up a Cursor Automation to automatically fix CI failures by connecting to Trunk’s CI failure investigation data via MCP. This is an extension of the Cursor CI Autofix template.

Set up the Trunk MCP using Bearer Authentication.

Recommended Cursor Automation Prompt

{
  "name": "CI Autofix v1",
  "description": "Detect CI failures on main and automatically open PRs",
  "triggers": [
    {
      "git": {
        "ciCompleted": {
          "repos": [
            "https://github.com/<repo>"
          ],
          "condition": 1,
          "ignoreBaseFailures": true
        }
      }
    }
  ],
  "actions": [
    {
      "gitPr": {}
    },
    {
      "mcp": {
        "server": {
          "name": "trunk"
        }
      }
    }
  ],
  "prompts": [
    {
      "prompt": "Your task is to fix CI failures on PRs..."
    }
  ],
  "memoryEnabled": true,
  "scope": "team_editable_user",
  "templateId": "ci-autofix"
}

We recommend the following conventions:

• Version your Automation names for more clarity (e.g., “CI Autofix v1”)
• Refine the prompt to avoid scanning GitHub logs in order to save time and tokens
• Be specific about your repository’s conventions and common failure patterns

Currently Cursor will create a pull request with a base of main. You will need to adjust the pull request base if you want to merge the fix into your PR.
