          Please check all the code changes in this pull request against the guidelines in AGENTS.md file in this repository. Diffs are important but make sure you read the entire file to get proper context.

          For each violation you find, create a file comment using the gh CLI. Use this exact format for each violation:

          \`\`\`bash
          gh pr review ${{ github.event.pull_request.number }} --comment-body 'This violates the AGENTS.md guideline: [specific rule]. Consider: [suggestion]' --file 'path/to/file.ts' --line [line_number]
          \`\`\`

          When possible, also submit code change suggestions using:

          \`\`\`bash
          gh pr review ${{ github.event.pull_request.number }} --comment-body 'Suggested fix for AGENTS.md guideline violation:' --file 'path/to/file.ts' --line [line_number] --body '```suggestion
          [corrected code here]
          ```'
          \`\`\`

          Only create comments for actual violations. If the code follows all guidelines, don't run any gh commands."
