Anthropic has introduced a new evaluation workflow for its Claude Code tool, designed to help developers test and measure the effectiveness of plugins. This system, called `claude plugin eval`, runs a plugin against realistic prompts and grades the output, comparing it to a baseline where the plugin is not used. It specifically addresses whether a plugin skill is triggered, if it remains functional after edits or model updates, and if it outperforms a bare model. The workflow includes six types of graders, with four being free and two requiring calls to a judge model, and provides a clear metric (Δ) to quantify the plugin's contribution. AI
IMPACT Enhances developer tooling for LLM plugin integration, potentially speeding up development cycles.
