Plugin Eval for Codex

Start from chat, then evaluate or benchmark locally.

Docs reviewedChecked 2026-09-20Runtime not tested

What it adds

Ask Codex to evaluate a plugin or skill, give you a full analysis of a named plugin such as game-studio, explain why it scored that way, show what to fix first, explain its token budget, measure real token usage, benchmark a plugin, or tell you what to run next. Plugin Eval keeps the path engineer-friendly: start with a natural chat request, then use the local plugin-eval start entrypoint or the routed workflow command it recommends.
