Copilot CLI Users Hunt Lighter Local Shell

The gap is real: people want command translation, not a repo-wide autonomous agent. The winning tools will stay narrow, fast, and conservative about execution.

• –GitHub Copilot CLI now supports local providers like Ollama, vLLM, and Foundry Local, so the “old Copilot CLI” workflow is still viable if you bring your own model.
• –`npcsh` is the closest community answer here: terminal-native, local-friendly, and built around slash commands plus agent personas rather than a heavyweight editor replacement.
• –Tiny general-purpose models usually fail at shell work because command generation needs syntax precision, OS-specific nuance, and strong instruction following more than raw creativity.
• –The safest UX is command suggestion with explicit confirmation, not autonomous execution; that keeps the tool useful without turning every typo into a bad `rm -rf` day.
