nixos

Quick Review

This skill orchestrates NixOS troubleshooting by combining multiple tools (nix-pro, nixos MCP, web search, sequential-thinking, context7). The description is somewhat vague ('resolve NixOS issues'), making it unclear when to invoke this versus using tools directly. Task knowledge is decent with specific guidance on SOPS secrets, research approach, and a file-based mutex pattern for build coordination. Structure is reasonable for a coordination skill. Novelty is moderate—it provides valuable orchestration (especially the build locking mechanism) but mainly composes existing tools. A CLI agent could attempt NixOS troubleshooting independently but would benefit from the build coordination logic and integrated workflow.
