Google Gemini CLI (~/.gemini/settings.json, GEMINI.md, commands/)
The interactive checkbox picker UI, the --dry-run preview mode, the --yes headless mode, and the automatic fallback skill generator are all gone.
Users who previously relied on /migrate to bring over Codex or Gemini settings will need to perform that migration manually by consulting the relevant config files directly.
Evidence
CLI argument parser entry removed (search for "Which agent to import from (codex, gemini)"); /migrate slash command registration removed; dozens of supporting functions deleted including the Codex scanner, Gemini scanner, MCP import logic, subagent writer, and interactive picker component.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
