Plugin Evals
A built-in plugin evaluation feature within Claude Code that supports baseline comparison, JSON and HTML format evaluation reports, and CI gating mechanisms. It transforms agent extension plugins from subjective debugging into quantifiable, testable engineering infrastructure.
Timeline (last 90 days)
Claude Code version 2.1.269 added the Plugin Evals feature.
Plugin Evals introduces a baseline comparisons mechanism.
Plugin Evals provides evaluation reports in both JSON and HTML formats.
Plugin Evals introduces a CI gates mechanism.
CI gates allow teams to set evaluation thresholds in the continuous integration pipeline, so that code can only pass when the plugin evaluation score meets the standard.
JSON reports are machine-readable, making them easy to integrate into automated pipelines or parse with scripts.
HTML reports are designed for human reading and present evaluation results in an intuitive manner.
By introducing a scoring baseline, Plugin Evals transforms probabilistic outputs into comparable quantitative metrics, making CI integration technically feasible.
The baseline comparison feature allows developers to quantitatively compare the current performance of a plugin against previous versions.
