Show HN: Id-agent – Token efficient UUID alternative for AI agents from github.com/vostride
7 by pranshuchittora 40m ago | |

Article: 16 min

id-agent is an ID library designed for AI agents that generates human-readable, token-efficient IDs at a lower cost than UUIDs while maintaining equivalent collision resistance.

id-agent could significantly reduce the token cost for AI agents, potentially enabling more efficient communication and data processing in AI systems.

id-agent produces word-based IDs that are more token-efficient than UUIDs, with a lower cost and better collision resistance.
The library supports various options like prefix, number of words, namespace for generating deterministic IDs.
It includes an API reference detailing functions such as ID generation, parsing, validation, alias creation, duplicate detection, and access to the wordlist.

Discussion (8):

The comment thread discusses a package that aims to improve efficiency and reduce errors in weaker models, with concerns about future changes in tokenization techniques and libraries. Suggestions for deterministic mapping are made, and questions about Python port and comparison with UUID are raised.

Smart idea but the concern can be that in the future, tokenization techniques and libraries may change

Counterarguments:

Great point. Also, wouldn't this taint the context with semantic meaning that affects response?
