Hey maintainers! 👋

I noticed that the Presubmit.ai workflow is failing on pull requests. I took a look at the workflow file and found a couple of issues that are causing the failures.

The Problem

The workflow in .github/workflows/presubmit.yml is failing with two errors:

1. Missing API Key: The workflow checks for LLM_API_KEY but it's not configured in the repo secrets
2. Invalid Model: The model gemini-1.5-flash isn't supported for the API version being used

This is blocking the AI reviewer from running on PRs, though it doesn't prevent merging since it's a separate check.

Current Workflow Code

- name: Check required secrets
  run: |
    if [ -z "${{ secrets.LLM_API_KEY }}" ]; then
      echo "Error: LLM_API_KEY secret is not configured"
      exit 1
    fi

- name: Run AI Reviewer
  uses: presubmit/ai-reviewer@latest
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
    LLM_API_KEY: ${{ secrets.LLM_API_KEY }}
    LLM_MODEL: "gemini-1.5-flash"

Possible Solutions

Option 1: Fix the workflow (if you want to keep the AI reviewer)

1. Add the LLM_API_KEY secret:

   • Go to Settings → Secrets and variables → Actions
   • Add a new secret named LLM_API_KEY with your Google AI API key

2. Update the model to a supported version:

   LLM_MODEL: "gemini-1.5-flash-002"
   # or another model from the supported list

Option 2: Make it optional (recommended for now)

If you're not ready to configure the API key, you could make the workflow optional so it doesn't block contributors:

- name: Check required secrets
  id: check-secrets
  run: |
    if [ -z "${{ secrets.LLM_API_KEY }}" ]; then
      echo "LLM_API_KEY not configured, skipping AI review"
      echo "skip=true" >> $GITHUB_OUTPUT
    fi

- name: Run AI Reviewer
  if: steps.check-secrets.outputs.skip != 'true'
  uses: presubmit/ai-reviewer@latest
  # ... rest of the config

Option 3: Disable the workflow temporarily

If the AI reviewer isn't critical right now, you could disable it:

• Go to Actions tab
• Select "Presubmit.ai" workflow
• Click the "..." menu
• Select "Disable workflow"

Impact

Right now this doesn't block PRs from being merged, but contributors might see a red X on their PRs which can be confusing. Making it optional or fixing it would improve the contributor experience.

Let me know if you'd like me to submit a PR for any of these solutions!

Thanks for maintaining this awesome repo! ��
