Proof of Usefulness Score
You're In Business

The project addresses a very real and specific issue in AI agent development (tool argument validation) and exhibits excellent market timing. However, as a newly published library (v0.1.0) with minimal verifiable traction, no current user metrics, and early-stage audience reach, it firmly falls into the calibration bracket for small-scale/early projects.

Project Details

Project URL
github.com/MukundaKatta/agentvet
Description
A tiny zero-dep JavaScript library that wraps each AI agent tool function with arg validation. If the model passes invalid arguments, agentvet throws a ToolArgError with an LLM-friendly retry hint so the model can self-correct. Five lines to wire into existing tool definitions; works with any agent framework.
Audience Reach
Early stage. agentvet v0.1.0 published on npm on 2026-04-25. Author has shipped 30+ open-source libraries (npm/PyPI/crates.io) under @mukundakatta; distribution flywheel established.
Target Users
Teams running AI agents whose tool functions still crash when the model passes bad arguments. Wrap once, the tool validates, the agent gets a typed retry hint and self-corrects. Zero new framework to learn.
