good point.we’re using “framework” intentionally because it goes beyond argument parsing. crust handles parsing, but also:type inference across args + flags end to end
compile-time validation (so mistakes fail before runtime)
plugin system with lifecycle hooks (help, version, autocomplete, etc.)
composable modules (prompts, styling, validation, build tooling)
auto-generates agent skills and modules from the CLI definitionsso it sits a layer above a traditional arg parser like yargs or commander, closer to something like oclif, but much lighter and bun-native.

This looks useful. But, it&#x27;s interesting how the backend-world and front-end world keep diverging. I must admit, I had no idea what this was from the title. &quot;CLI framework&quot;? But in backend-land, these would typically be called &quot;argument parsers&quot; or &quot;command line argument parsers&quot;. But maybe I am missing some of the functionality.

this is cool! i&#x27;d recommend fleshing out the README. Clicked on the link before the discussion and was a tad confused.

I understand, but that&#x27;s already implied by a 0.y.z version number.

thanks for the catch, what we meant is that we’re not committing to strict stability guarantees yet, so APIs may still change as we iterate toward 1.0.

&gt; Versions before 1.0 do not strictly follow semantic versioning.Sorry for being nitpicky, but yes they do. Semantic versioning[0] allows arbitrary changes while the major version is 0:&gt; Major version zero (0.y.z) is for initial development. Anything MAY change at any time. The public API SHOULD NOT be considered stable.[0]: <a href="https:&#x2F;&#x2F;semver.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;semver.org&#x2F;</a>

Isn&#x27;t a standalone Bun binary like 50MB because it has to bundle the runtime? How could this get smaller?

nice, congrats on launch. To get an idea... what&#x27;s the size of a standalone hello world cli binary?

one of the examples would be trynia.ai (search and index api for ai agents)here is github: github.com&#x2F;nozomio-labs&#x2F;nia-cli

Is there an examples section? Would be helpful to see a demo

thanks for flagging! the post itself works, just the link at the bottom

Psst, the GitHub link in your post is broken (it should be <a href="https:&#x2F;&#x2F;github.com&#x2F;chenxin-yan&#x2F;crust" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;chenxin-yan&#x2F;crust</a>).
