Closes: N/A (SonarQube code quality improvements)

Summary

This PR addresses two HIGH severity SonarQube issues:

  1. go:S1192 - String literals should not be duplicated (discussions.go): Extracted discussionOwnerOption() and discussionRepoOption() helper functions to eliminate duplicated owner/repo parameter definitions across 4 functions.

  2. go:S3776 - Cognitive Complexity should not be too high (repository_resource.go): Refactored RepositoryResourceContentsHandler by extracting helper functions to reduce cognitive complexity.

Changes

discussions.go

  • Added discussionOwnerOption() and discussionRepoOption() helper functions returning mcp.ToolOption
  • Replaced inline owner/repo parameter definitions with helper function calls in ListDiscussions, GetDiscussion, GetDiscussionComments, ListDiscussionCategories
  • Uses existing DescriptionRepositoryOwner and DescriptionRepositoryName constants

repository_resource.go

  • Extracted extractStringArg() - extracts string arguments from request
  • Extracted extractPathArg() - extracts and joins path parts
  • Extracted resolveRefOptions() - resolves ref options (sha/branch/tag/prNumber)
  • Extracted determineMimeType() - determines MIME type for files
  • Extracted buildResourceContents() - builds appropriate resource contents based on MIME type
  • Simplified main handler with cleaner control flow

Human Review Checklist

  • Verify resolveRefOptions early-return pattern is correct (original code allowed later ref types to override earlier ones; new code returns on first match)
  • Confirm buildResourceContents correctly handles text vs blob content types
  • Verify discussions.go helper functions produce identical tool definitions
  • Check that path validation ("directories are not supported") still occurs at the right point

Testing

  • All existing tests pass
  • Lint checks pass
  • SonarCloud quality gate passed (0.0% duplication on new code)

- Replace duplicated string literals 'Repository owner' and 'Repository name'
  with existing constants DescriptionRepositoryOwner and DescriptionRepositoryName
  from actions.go (fixes go:S1192)

- Reduce cognitive complexity of ListDiscussions function by extracting:
  - discussionNode type for GraphQL response structure
  - discussionNodeToIssue helper function for mapping nodes to GitHub Issue objects
  - fetchDiscussionNodes helper function for GraphQL query execution
  (fixes go:S3776)

…educe duplication

- Add discussionOwnerOption() and discussionRepoOption() helper functions
- Replace inline mcp.WithString owner/repo blocks with helper function calls
- This breaks the clone regions with other files (code_scanning.go, repositories.go, etc.)
- Reduces SonarCloud duplication from 3.6% to below 3% threshold
