The request names @holycodex/plugin, which does not appear among the candidate products, so no source describes it. The closest matches for building or scaffolding a plugin are the Codex plugin-creator action from OpenAI 11 and Claude Code plugin development tools from Anthropic 16; the answer cannot confirm what @holycodex/plugin itself does.
A question back: Is @holycodex/plugin a plugin for Codex, Claude Code, or another platform, and what should it do? Share its npm page or repository so I can match it to the right tooling.
