Skills
No skill passed the confidence bar. Weak matches go to review instead of this page: an AI pass that has to quote the description, then a person.
AI-resilient: 2 of 5
- No: Physical, lab or field work
- Yes: Live work with people · "intermediate"
- Yes: Judgment someone is accountable for · "policy"
- No: A craft you practice with your hands or body
- No: Small, in-person format
The checks lean on Microsoft Research, Working with AI (2025), which found generative AI applies least to physical work and hands-on work with people. A signal, not a promise. How the score works
