  Hi HN,

    I built RLM Analyzer, an open-source tool for analyzing codebases using       
    Recursive Language Models.                                                    
                                                                                  
    Problem: LLMs have context limits. Large codebases don't fit.                 
                                                                                  
    Solution: Based on MIT CSAIL's RLM paper (arXiv:2512.24601), the AI writes    
    code to explore files and delegates analysis to sub-LLMs. Key innovations:    
                                                                                  
    - Context compression (50-70% token savings)                                  
    - Sliding window history                                                      
    - Memory bank for key findings                                                
    - Adaptive compression based on usage                                         
                                                                                  
    Example commands:                                                             
      rlm summary          # Codebase overview                                    
      rlm security         # Vulnerability scan                                   
      rlm arch             # Architecture analysis                                
      rlm ask "How does auth work?"                                               
                                                                                  
    Also works as an MCP server with Claude Code/Cursor, saving 60-73% on API     
    costs by offloading to Gemini.

    NPM: https://www.npmjs.com/package/rlm-analyzer                               
                                                                                  
    Built with TypeScript, uses Gemini API. Feedback welcome!
