Claude Code plugin struggles with automated evaluations, reveals model performance gaps

By PulseAugur Editorial · [1 sources] ·

A developer created a plugin for Claude Code to automate project setup, but found its initial performance lacking through automated evaluations. The plugin, designed to generate project scaffolding based on a one-paragraph description, initially failed to trigger correctly and produced incorrect or incomplete setups. Issues included the plugin's trigger conditions being too narrow, graders misinterpreting intended behavior, and a Claude Code update causing regressions. Furthermore, testing with smaller models like Haiku and Sonnet revealed significant performance drops compared to the default model. AI
