Show HN: Sk` – manage AI agent skills across Claude, codex, opencode, et all (github.com)

A new tool called Sk` has been announced, designed to streamline the management of AI agent skills across various coding platforms like Claude Code, Codex, and OpenCode. Users can install it via Homebrew, npm, or Scoop, then initialize and add skills using simple commands. One of its standout features is the ability to define skills once in a shared manifest file (agents.toml) and synchronize them across all enabled agents. This significantly enhances team collaboration and efficiency, allowing multiple agents to leverage the same skills seamlessly. The significance of Sk` lies in its cross-agent compatibility, enabling skills developed for Claude Code to be utilized in Codex and OpenCode, thus standardizing the tools used by AI developers. Technical features such as smart reconciliation—only updating what has changed—and local package symlinking for real-time editing enhance the development experience. The tool allows skills to be sourced from GitHub or local paths, enabling a flexible and version-controlled environment for skill management. Sk` provides a structured and efficient framework that could accelerate AI development processes, making it a valuable addition to the AI/ML community.
