task-observer - One Skill to Rule Them All The meta-skill that builds and improves all your skills, including itself. In the first six months of using this meta-skill, it logged and applied over 900 improvements across my 50 skills, most of which were themselves created based on observations by the meta-skill. This meta-skill, called "task-observer", is a practical application of the Augmented Expertise methodology, an AI framework for knowledge workers. However, users have reported successful integrations into their Hermes and Openclaw setups, so it works equally well with autonomous agents. Why you should use this meta-skill Creating skills is powerful but time-consuming. The skills that do get built stay frozen: they never learn from how you actually use them. Task Observer fixes those problems.

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
