I built two CLI tools that save me time on every project

Every project I start hits the same two friction points:

I stage my changes and stare at the terminal thinking "how do I word this commit?"
I clone a repo, copy .env.example to .env, run the app, and get a cryptic error because three keys are missing from .env.example.

So I spent a weekend building two small tools to fix them permanently.

gitmage — Stop writing commit messages

npm install -g gitmage
git add .
gitmage

It reads your staged diff, sends it to AI (Groq for free, Claude Haiku for ~$0.0001),
and presents 3 commit options you navigate with arrow keys.

Hit enter to commit. Hit R to regenerate. That's it.

Flags worth knowing:

The workflow I used to do:

cp .env.example .env

The workflow now:

envpatch init # creates .env from .env.example

envpatch check # confirms nothing is missing

And when a teammate adds a new key to .env.example:

envpatch sync # adds the missing keys to your .env automatically

Also works great in CI:

Both tools are TypeScript, published on npm, MIT licensed.
Would love feedback if you try them.
