SkillAlchemy
Turn people, methods, and experience into installable, reusable agent skills.
SkillAlchemy is an open-world agent skill creation system. It discovers omitted requirements, extracts executable procedures from public sources, and produces skills that agents can install and use directly.
Results
We evaluate SkillAlchemy on 87 tasks from SkillsBench v1.1 across four agent–model configurations. SkillAlchemy achieves the highest overall task pass rate in 3 of 4 configurations.
Averaged across all configurations, SkillAlchemy reaches a 55.8% task pass rate, improving over no-skill execution by 19.9 percentage points. It also slightly surpasses human-curated skills on average.
Features
-
Distill people — Build Persona Skills from public evidence about decisions, failures, values, and communication patterns.
-
Distill methods — Turn books, methodologies, repositories, or interviews into executable Skills with conditions, steps, branches, and failure handling.
-
Fuse Skills — Combine existing workflows, domain knowledge, or working styles into a new capability.
-
Stay evidence-grounded — Separate reusable procedures, scoped cases, and unsupported content to reduce unjustified generalization.
