obra/the-elements-of-style ? reverse-engineered prompt

Build me a Claude Code plugin that gives Claude access to William Strunk Jr.’s The Elements of Style as a writing reference.

I want it to help with clear, precise writing when I’m working on documentation, user facing text, or anything that needs tighter prose. The plugin should include a skill called writing clearly and concisely that tells Claude when to use the guide, shows the main rules at a glance, and reminds it that the full reference is large so it should only load it when it is actually editing or writing text. If the context is too small, it should suggest using a subagent for copyediting.

Also include the full 1918 public domain text in a clean markdown or HTML reference file, with the usage rules, composition rules, and the list of commonly misused words. Keep it organized so Claude can quickly search and apply the guidance. If you need to, look up current docs online to make sure the plugin format is correct.
