Greptile Summary

This PR expands the OpenAI Agents SDK documentation page with a comprehensive Quick Start guide, tabbed proxy vs. direct usage examples, usage tracking instructions, and environment variable references. It also adds the page to the "Agent SDKs" sidebar category.

• Build-breaking bug in sidebars.js: The new sidebar entry uses a raw filesystem path (litellm/docs/my-website/docs/projects/openai-agents.md) instead of the Docusaurus doc ID (projects/openai-agents). This will cause the documentation site build to fail.
• The markdown content itself is well-structured and follows existing documentation conventions.

Confidence Score: 2/5

• The sidebar change will break the documentation build and must be fixed before merging.
• The documentation content is good, but the sidebar entry uses an incorrect path format that will prevent the Docusaurus site from building. This is a simple fix (change to "projects/openai-agents") but blocks the PR as-is.
• Pay close attention to docs/my-website/sidebars.js — the new entry on line 179 uses an invalid doc ID format.

Important Files Changed

Filename	Overview
docs/my-website/sidebars.js	Sidebar entry uses full filesystem path instead of Docusaurus doc ID — will break the documentation build.
docs/my-website/docs/projects/openai-agents.md	Documentation content is well-structured with clear Quick Start guide, tabbed examples for proxy vs. direct usage, usage tracking, and environment variable reference. No issues found.
