The investigation found strong documentary and code-structure evidence that the repo ships a real, non-trivial detector engine (detector/patterns.js, ~139KB, with its own CLI in bin/avoid-ai-writing.js and multiple test files) rather than just prose describing one. The detector's README describes it as a zero-dependency, deterministic engine that runs in Node >=18 or the browser, and the main README's demo material describes it flagging 13 AI-writing patterns in a sample paragraph and scoring a clean rewrite 0/100. CATEGORIES.md shows the engine internally exposes 54 issue types, and categories.test.js appears to enforce that documented counts match the code's TYPE_LABELS. However, no command was actually run against the detector to verify it executes and flags patterns on a sample text — the one bash_code_execution call made was a no-op ('echo skip') and did not attempt to invoke node or the CLI, so no runtime attempt was made and no blocker (such as missing Node.js) was actually demonstrated. The claim therefore remains untested rather than refuted or confirmed; the investigation stopped short of executing the detector without evidence establishing why, which is a gap in the investigation itself rather than a demonstrated environment limitation.
