| # SkillScreen-2B-MSD |
|
|
| This model is described in the paper: [SkillScreen: High-Recall Screening of Malicious Agent Skills with Decision Models](https://huggingface.co/papers/2610.17727). |
|
|
| 2B decision model for detecting malicious agent skills from `SKILL.md`. Trained on MaliciousSkillBench using Malicious-Structural-Disjoint (MSD), with an 8K input budget. |
|
|
| Based on [OpenJev 2B](https://huggingface.co/AlexWortega/openjev). Full weights are at the root. The original LoRA adapter and classification head are in `adapter/`. |
|
|
