Show HN: Muscle-Mem, a behavior cache for AI agents

Hi HN! Erik here from Pig.dev, and today I'd like to share a new project we've just open sourced:

Muscle Mem is an SDK that records your agent's tool-calling patterns as it solves tasks, and will deterministically replay those learned trajectories whenever the task is encountered again, falling back to agent mode if edge cases are detected. Like a JIT compiler, for behaviors.

At Pig, we built computer-use agents for automating legacy Windows applications (healthcare, lending, manufacturi

Show HN: Semantic Calculator (king-man+woman=?)

I've been playing with embeddings and wanted to try out what results the embedding layer will produce based on just word-by-word input and addition / subtraction, beyond what many videos / papers mention (like the obvious king-man+woman=queen). So I built something that doesn't just give the first answer, but ranks the matches based on distance / cosine symmetry. I polished it a bit so that others can try it out, too.

For now, I only have nouns (and some proper nouns) in the dataset, and p
