Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request updates the finalize-pr skill documentation to reflect a change in how code simplification is handled. It transitions from using an external code-simplifier tool to leveraging a newly integrated /simplify command within Claude Code, streamlining the workflow and removing an obsolete dependency.

Highlights

• Deprecation of code-simplifier: The external code-simplifier reference has been replaced with the built-in /simplify skill, as Claude Code now bundles this functionality natively.
• Documentation Update: All six occurrences of code-simplifier within the SKILL.md documentation for the finalize-pr workflow have been updated to /simplify.

Changelog

• github-workflows/skills/finalize-pr/SKILL.md
  • Replaced all instances of 'code-simplifier' with '/simplify' to reflect the new built-in functionality.
