SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill streamlines the often error-prone process of updating package versions and their SHA256 checksums within Nix/pkgs directories. It ensures consistency, security, and reduces manual effort in maintaining Nix-based package repositories.

Core Features & Use Cases

Automated Version Updates: Fetches release manifests from URLs, parses them, and updates package versions in nix/pkgs/versions.json.
Checksum Management: Extracts and applies correct SHA256 checksums for various platforms (aarch64-darwin, x86_64-darwin, aarch64-linux, x86_64-linux) in corresponding package .nix files.
Nix/pkgs Integration: Designed for the specific directory structure and file formats of Nix package repositories, ensuring proper validation of updates.

Quick Start

Update the 'rust-mcp-filesystem' package to version '0.3.12' using the manifest from 'https://github.com/towry/rust-mcp-filesystem/releases/download/v0.3.12/dist-manifest.json'.
