Show HN: Id-agent – Token efficient UUID alternative for AI agents

What's wrong with UUIDs? Oh, they cost a lot to generate? Why are you trying to generate them with autocomplete? There's a spec, libraries for nearly any language...

Why.

@algernon wow, this is unusually stupid, esp. if we consider: https://www.schneier.com/blog/archives/2026/02/llms-generate-predictable-passwords.html

@algernon "Token efficient", another oxymoron like "military intelligence"

@algernon I'm pretty sure generating UUIDs with tokens is how you get a bunch of collisions.

Unless they're getting the LLM to tool call an actual UUID library, but I guess that means the LLM needs to figure out that it needs to tool call an actual UUID library... which come to think of it might be where the tokens are going..... ​

@brib if it called a lib functiin, it wouldn't cost so many tokens.

This is just simply a terrible idea.
