I started adding cli's for a few things last week. Initially just for myself but it didn't take me long to figure out that codex / claude code / etc. are pretty good at figuring out cli's as well. And creating them. If you have APIs, generating a usable cli for them is pretty straightforward. With lots of nice features, documentation, bash/zsh autocomplete support and other bells and whistles. Doing that manually is a lot of repetitive work. Having that stuff generated on the other hand doesn't have to take a lot of time.

The combination with skills is where it really shines. And you can generate those as well for your shiny new cli. Once you have that in place, you can drive your API agentically to do non trivial things in it.

One of my OSS projects, jillesvangurp/ktsearch now has such a cli. Ktsearch is a kotlin multiplatform library for Elasticsearch and Opensearch. The new cli compiles to jvm and native linux/mac binaries. I've been playing with this for the last week and adding a few features. It's very nice to have around if you deal with opensearch/elasticsearch clusters. No more messy curl commands and json blobs.

And I've gotten codex to use it for me for a few things already.

Yeah that was my strategy yesterday and it worked. I ditched an MCP server and had Claude write its own CLI for the API
