The strings.Title function has been deprecated since Go 1.18 and should not be used. According to the Go documentation, strings.Title uses simple case-folding which doesn't handle Unicode correctly.

For title-casing a single word like "good", "excellent", etc., use cases.Title(language.Und).String(qualityResult.Assessment) from the golang.org/x/text/cases package, or for simple English strings, implement a custom function like:

func capitalizeFirst(s string) string {
    if s == "" {
        return s
    }
    return strings.ToUpper(s[:1]) + s[1:]
}

Note that the AssessQuality method in internal/integrations/gemini/llm.go already normalizes the assessment to lowercase (line 279), so this formatting should be consistently applied.

The response builder always creates a comment with at least the header and footer, even when all content sections are empty. This could result in posting comments with minimal value (just "## 🤖 Simili Triage Report" and the footer) when no quality assessment, labels, transfers, similar issues, or duplicates are found.

Consider adding a check to only build and store the comment if at least one content section is non-empty. For example:

func (s *ResponseBuilder) Run(ctx *pipeline.Context) error {
    // Check if there's any content to report
    hasContent := s.hasAnyContent(ctx)
    if !hasContent {
        log.Printf("[response_builder] No triage content to report, skipping comment")
        return nil
    }
    
    comment := s.buildTriageSummary(ctx)
    ctx.Metadata["comment"] = comment
    return nil
}

func (s *ResponseBuilder) hasAnyContent(ctx *pipeline.Context) bool {
    return s.buildQualitySection(ctx) != "" ||
           s.buildLabelsSection(ctx) != "" ||
           s.buildTransferSection(ctx) != "" ||
           s.buildSimilarSection(ctx) != "" ||
           s.buildDuplicateSection(ctx) != ""
}

This ensures the bot only comments when it has actionable information to provide.

The duplicate confidence threshold (0.8) is hardcoded in the duplicate detector step. This threshold determines when an issue is marked as a duplicate and should ideally be configurable to allow administrators to tune the sensitivity based on their needs.

Consider adding a DuplicateConfidenceThreshold field to the config (similar to HighConfidence and MediumConfidence in TransferConfig) to make this value configurable. A reasonable default would be 0.8, but teams may want to adjust it based on their tolerance for false positives/negatives.

The GitHub username has been changed from "Kavirubc" to "kavirubc" (lowercase) in the modified files. This creates an inconsistency with the rest of the codebase, where 30+ files still use "Kavirubc" with uppercase K.

For consistency, either:

1. Update all files to use the lowercase version if that's the correct username, or
2. Keep the existing uppercase version

GitHub usernames are case-insensitive for URL purposes, but it's better to be consistent across the codebase.

The section title is "Labels Applied" but at the time the response builder runs, the labels haven't actually been applied yet - they're just suggested. The actual application happens later in the action_executor step.

Consider changing the title to "Suggested Labels" or "Labels To Apply" to accurately reflect that these are suggestions that will be applied, not labels that have already been applied. This would be more accurate and prevent user confusion.
