Greptile Summary

This PR updates site metadata, removes unused static assets, and standardizes contact emails across the codebase.

Key Changes:

• Updated social media metadata to use new logo paths (/logo/426-240/primary/small.png) and changed Twitter handle from @simstudioai to @simdotai
• Migrated from static robots.txt to dynamic generation with comprehensive bot rules (including AI/LLM crawlers like GPTBot, ClaudeBot, PerplexityBot)
• Added RFC 9116-compliant security.txt at .well-known/security.txt with redirect from /security.txt
• Created new /llms-full.txt endpoint with detailed product documentation for LLM discovery
• Restructured /llms.txt with better formatting and markdown content-type
• Removed priority fields from sitemap (aligns with Next.js best practices)
• Updated developer count from 30,000+ to 60,000+ in manifest
• Updated pricing validity dates from 2025 to 2026 in structured data
• Standardized email contacts: support@sim.ai → help@sim.ai in Python SDK
• Cleaned up unused static assets: /social/*.png, /sim.svg, /sim.png, /icon.svg, /logo-sim.svg
• Fixed language alternate path from /en-US to / in metadata

Confidence Score: 5/5

• This PR is safe to merge with no identified risks
• All changes are metadata updates, asset cleanup, and documentation improvements. The new logo paths exist in the repository, no code logic is affected, and all changes follow Next.js best practices. The dynamic robots.txt and security.txt implementations are RFC-compliant and well-structured.
• No files require special attention
