Because I didn't have enough agent-related surface area to explore, I'm now speccing out a possible Go query engine inspired by Rust's trustfall.
It's because of agents, sorta - I've been planning a v2 rewrite of skill-validator with a pluggable content policy (and many other things). But the Go ecosystem options for this are - not quite what I'm looking for.
My good pal Claude says I should just ship v2 with one of the suboptimal but extant options. No need to write a whole separate library - just make the shape fit what's available.
Maybe my brain just needs something that isn't agent-shaped to work on. Or maybe it's because people keep coming to me with graph-related stuff, and building a graph-based query engine in Go lets me explore that domain so I can make better assessments of the agent-related graph things that keep dropping in my lap.
Who knows if I will actually ship anything, but it's a fun exercise so far.
