GitHub just released Spec Kit for spec driven development.

Has anyone tried installing and using it with Gemini CLI? Curious about workflow fit and your experience

I've been using it pretty flawlessly, there's a few hiccups here or there, for example it really doesn't like having the gemini cli run from outside of the actual project dir.

Outside of that it's pretty great. I am using it with a Gemini Code Assist subscription (monthly, about 23 bucks CAD). Add to your bashrc (or whichever shell you use) export GEMINI_API_KEY=<api key here> then exec $SHELL

I'm using the npx execution of the CLI tied to an alias (gemini) with a copy of the cloned spec-kit repo in my home directory. Just use /directory add </path/to/spec-kit-dir> to add it to the context.

It should pick up the API key and log you in automatically. From there just ask it to use spec-kit to develop the specs, then execute the action items with Gemini.

For example I generated a series of markdown docs with Claude Sonnet 4 to describe the lifecycle of a CLI tool I want to develop for some homelab management. It ingested all of those docs, then used that info to develop the spec-kit framework for the project. From here on out I'll default to using spec kit directly.
