SkillNet Validity Report
Key Takeaways
- SkillNet validity: do peer-reviewed skills actually perform better than unreviewed ones?
- Controlled study: 87% of SkillNet-validated skills passed production acceptance tests vs 61% baseline
- Validity certificate decays: skills need re-validation after model updates or dependency changes
- Human expert review still outperforms automated validation for edge-case correctness
- SkillNet’s automated test suite catches tool misuse but misses prompt injection vulnerabilities
Summary
This validity report assesses whether SkillNet’s peer-review and automated testing pipeline produces meaningfully better skills. The central finding: validated skills show a 26-percentage-point improvement in production acceptance rates, confirming the value of structured review. However, the improvement concentrates in well-defined task categories (data transformation, API calls) and nearly disappears for open-ended reasoning tasks.
The temporal validity problem is newly identified: a skill validated against GPT-4 Turbo may behave differently after a model update, because skills encode assumptions about model behavior that can silently break. SkillNet’s current approach treats skill validity as a static certificate rather than a living assessment.
Recommendation: implement continuous monitoring via a shadow-mode execution harness that flags behavioral drift post-validation. Human expert review should remain mandatory for skills touching financial, medical, or legal domains.
