23.4What Actually Happened to Its Thesis

This is the interesting part. Vibium's January 2026 pitch — CLI skills beat MCP on token economics — won the argument while the tool itself stayed niche. Microsoft shipped @playwright/cli with a --skills flag and now recommends CLI over its own MCP server for coding agents (~4x token savings). The idea propagated faster than the implementation. That happens constantly in this industry, and being able to narrate a live example of it is worth more in an architect interview than fluency in any single tool.
