Pack Agent: Pack skills, rules, and MCP into .pack.zip and install to harness

pack-agent is an npm package designed to simplify DeepSeek Harness (DSH) and agent configuration management, adhering to the philosophy that "everything is a plugin." It addresses the issues of error-prone and difficult-to-uninstall manual copying of skills, rules, and MCP configurations across different harnesses such as Claude Code and Codex. The plugin packages these configurations into .pack.zip files via commands and installs them into the target harness, utilizing an installation ledger to achieve clean uninstallation. It supports multiple harnesses including claude-code and codex, requires Bun >= 1.1, and is licensed under the MIT License. Core functions include initialization, export, installation, and configuration ejection (uninstall), and it supports Model Context Protocol (MCP).
