Geoffrey Litt: The Document Editor Is the Next IDE as Prompts Become Executable Software
ivanhzhao · x · 2026-09-18
Geoffrey Litt argues that a document with a prompt is now a unit of executable software: sharing the document is sharing the program, no app store required.
Talking to non-engineers who use AI skills, he found classic software engineering problems re-emerging in a new medium:
- How do you know a skill still works after edits?
- How do you collaborate and suggest changes without breaking the running version?
- How do you discover useful modules, and who controls what ships?
Litt sees this as a chance to reinvent tooling for these problems. Quoting narphorium raises the evals angle: if anyone can edit skills, everyone must ensure changes don't fix one thing and break another — essentially a regression-testing problem.
