what is essence fr?

Essence is a tool that trims the writing an AI coding assistant produces down to only what a reader actually needs. It targets things like chat replies, code comments, commit messages, pull request descriptions, and documentation, but leaves private scratch notes and internal reasoning untouched since those were never meant for a reader anyway. The problem it addresses is that AI generated writing often carries leftover baggage from the conversation that produced it, things like hedging phrases, comments about what was asked, and references to earlier drafts the reader never saw. Essence removes that baggage while keeping full sentences and normal grammar, so a reader with no memory of the conversation can understand the result completely on its own. The README points out this is different from a related project called caveman, which shortens writing using telegraphic grammar and dropped words. Essence instead keeps full grammar but removes sentences that do not carry real meaning, so the two tools solve different problems and can be used together. The README shows several before and after examples, like a chat reply that gets trimmed from a rambling explanation full of hedges down to two direct sentences, or a code comment that becomes a single short line stating only the fact a future reader would need. The tool comes with a small set of commands. One toggles the filter on or off, since it runs by default every session. Others are specialized for writing pull request descriptions, rewriting an existing document or comment file in place while keeping code and links untouched, and writing commit messages in a standard format without any AI attribution note. Installing it in Claude Code takes one command since the plugin lives directly in the repository. For other AI coding tools such as Codex, Gemini, Cursor, Windsurf, or Cline, you clone the repository and run an installer script that detects which tools you have and sets up the rules file each one uses. The README does not state a license for the project.
