Pretty boring tech (ts/rust/go), claude opus 4.7. The difference is probably context engineering. Your skill files in Ditto are very good. I thought spec driven development would do the same thing but it hasn't, and I haven't invested in writing skills for everything.

Skills on special unit of work that you do often are the unlock. Not generic skills but specific skills that accomplish something e.g get all components and their dependency related to a feature in the same file. Another skill could be move specific components from a file to another file along with its dependencies and create the equivalent UI stories. Another one could be resolved duplicate imports. It then becomes possible to build skills where each step is pointing to another skill so that at the very list the agent does things correctly. This has been the Middle ground imo
