Historical expert output can be converted directly into agent capability: Every turned 30,000 historical editorial edits into a 'skill' inside their agent so it can make Google Docs suggestions matching editorial taste. The mechanism is treating an archive of prior human work as both the training signal and the acceptance criterion for a skill, rather than writing prompts from scratch.
This is a concrete recipe for automating qualitative knowledge work: mine a person's or team's past work samples, encode them as skills plus evaluation rubrics, and measure model output against the historical pattern. It shifts skill authoring from prompt engineering to corpus-derived behavior.
Any domain with a large archive of reviewed professional output (legal redlines, code review comments, design critiques) can be compressed into a domain skill whose quality is judged against the archive itself.
