Why exactly do we need a new language? The agents I write get access to a subset of the Python SDK (i.e. non-destructive), packages, and custom functions. All this ceremony around tools and pseudo-RPC seems pointless given LLMs are extremely capable of assembling code by themselves.

I'm imagining something more like Rexx with quite high level commands. But that certainly blurs the line between programming language and shell.

The reason for choosing higher level constructs is token use. We certainly reduce the number of tokens by using a shell like command language, But of course that also reduces expressiveness.

I've been meaning to get round to Plan 9 style where the LLM reads and writes from files rather than running commands. I'm not sure whether that's going to be more useful than just running commands. is for an end user because they only have to think about one paradigm - reading/writing files.

Does this "non destructive subset of python SDK" exist today, without needing to bring, say, a whole webassembly runtime?

I am hoping something like CEL (with verifiable runtime guarantees) but the syntax being a subset of Python.

Woah woah woah, you’re ignoring a whole revenue stream caused by deliberately complicating the ecosystem, and then selling tools and consulting to “make it simpler”!

Think of all the new yachts our mega-rich tech-bros could have by doing this!
