Bash (even if you find a way to compile it to wasm) will need POSIX to operate and also file system.
Bashkit reimplements portion of POSIX and have own FS, so there is no need a dependency on any resources outside of process (except CPU and Mem) if you do not need them. You effectively can run tons of isolated instances in parallel.
Yeh, bashkit was in general developed mostly for agentic runtimes. So it might be a good fit, especially if there is a need to run agent in some isolation.
Regarding incorporating in Go, it is actually long due to make sure that bashkit have stable ABI, I think I need to look at it next week, that would allow having support for Go, C++ and Zig.
I however would rather recomend starting from https://github.com/ewhauser/gbash , this library is philosophically very similar, and it is native Go.
Basically a backbone of your own agent in rust. All common agentic features and optimizations: streaming, multi-provider, multi-model, multi-modal, MCP, AGENTS.md, context management, tool_search, different sandboxes, conectors, bacground angets, monitors, etc and etc.
Agents talk to agents: they negotiate, buy, align, and communicate. FCP is the simplest shared channel for that.
The idea is to provide the simplest possible HTTP-based way for actors to communicate, where everything — authentication, protocols, tools, and capabilities — is negotiated through plain-text conversation.
It assumes that, at some point, all actors (agents) will be able to make HTTP calls, and that this capability alone is the bare minimum required for communication.
I needed something in-process that would allow AI agents to perform complex orchestration-something that could run in multitenant environments.
I started with a custom language, but that didn’t work well, the more features I added, the more custom instructions I had to include in the system prompt. I then experimented with hosting Lua, which was quite fun. After that, I considered Python, but it felt too heavy (though I might be wrong—especially considering Monty). Then Vercel Labs released just-bash, which led me to build a virtual Bash environment called Bashkit.
My current goal is to provide an in-memory, in-process Bash that can handle common agentic scenarios without requiring a full, flagged sandbox.
It is implemented in Rust and currently available for Rust and Python.
