One Skill to Rule Them All

One Skill to Rule Them All is a meta-skill that watches work sessions to improve existing skills and propose new ones.

Task Observer is a meta-skill designed to improve all your skills and propose new skill candidates based on your work sessions. It operates during both human-led AI sessions and autonomous agent tasks, logging thousands of observations to refine skill implementations. Users point their preferred AI companion at the repository to set it up for their specific environment. The tool integrates into environments such as Claude Cowork, Hermes, Openclaw, Obsidian, and Codex. It is intended for knowledge workers seeking to automate their skill creation and make their skills self-improving.
