Provides ephemeral Nix-backed execution environments for running Ruby code with on-demand package dependencies from nixpkgs.
AlicenseBqualityDmaintenanceEnables creation of ephemeral, polyglot development environments using Nix for on-demand execution of code with specific dependencies across Python, Node.js, Ruby, R, and Lua without cluttering the system.2MITWhy this server?
Provides context-efficient reading of Ruby source code through specialized compression filters.
AlicenseAqualityDmaintenanceProvides code-aware context compression by stripping comments, docstrings, and whitespace while maintaining full logic fidelity for AI agents. It features tools for architectural mapping, symbol searching, and token-budgeted multi-file reading.96 npm4MITWhy this server?
Scans Ruby source and configuration files for project inventory and static-analysis review.
AlicenseBqualityCmaintenanceEnables AI coding agents to perform evidence-based, read-only audits of supported software projects by exposing bounded project inventory and static-analysis findings for discovery, code review, integration tracing, security, and tests. Reports are returned as Markdown or JSON directly in the tool response, with no code executed or files written.8281 npmMIT
