Every's team reproduced @hammermt's "Write Like Mike" experiment: building four kinds of Claude skills that imitate his writing style, judged blind against his real posts.
- Key finding: tuning beats writing — tuned skills won up to 95% of held-out posts, while a skill Claude wrote in one shot actually lost to having no skill at all.
- Practical takeaway for anyone building Claude skills or agent personas: style skills reward iterative tuning, not one-shot generation.
