Format Agnostic Skill Resource Bundling With Optional Scripts And References

via “extensible skills system with .skill archive loading and composition”

An open-source long-horizon SuperAgent harness that researches, codes, and creates. With the help of sandboxes, memories, tools, skill, subagents and message gateway, it handles different levels of tasks that could take minutes to hours.

Unique: Uses .skill archives as self-contained bundles combining prompts, tools, and configuration, enabling true plugin-like extensibility. Skills are composed at runtime into a unified agent rather than running as separate processes, allowing seamless tool sharing and prompt composition.
