Greptile Overview

Greptile Summary

This PR adds three database indexes to the LiteLLM_VerificationToken table to improve query performance for common access patterns:

• user_id, team_id composite index - optimizes queries filtering by user and team combinations
• team_id single-column index - optimizes queries filtering by team only
• budget_reset_at, expires composite index - optimizes queries filtering tokens by budget reset time and expiration

The indexes are consistently applied across all three Prisma schema files (schema.prisma, litellm/proxy/schema.prisma, litellm-proxy-extras/litellm_proxy_extras/schema.prisma) with helpful SQL query comments documenting the specific query patterns being optimized. The migration file correctly creates these indexes using standard PostgreSQL syntax.

Confidence Score: 5/5

• This PR is safe to merge - it only adds performance-improving indexes without modifying data or logic
• The changes are purely additive (adding database indexes) with no code logic modifications. The indexes are properly defined in both Prisma schemas and the migration SQL, follow PostgreSQL best practices, and address legitimate performance concerns for common query patterns on the VerificationToken table.
• No files require special attention
