blader/humanizer: Agent skill for removing AI-generated text traces

Humanizer is an Agent skill built on Wikipedia's "AI writing characteristics" guide, with 26 built-in AI writing pattern detections including "not X but Y," "one-sentence closers," and "deliberate setup." It supports Claude Code, Codex, Gemini CLI, GitHub Copilot, Windsurf, and other Agent tools, invoked via the /humanizer command after installation. In blind tests, judges preferred Humanizer's rewritten versions over the original AI text in all 16 cases. The tool flags all detected AI traces sorted by intensity, then drafts a rewrite, checking against patterns and original claims before outputting the final version. Factual details like filenames, numbers, dates, and citations must come from the source; when missing, it asks rather than fabricates. When pointing to files, it only modifies prose, preserving code, data, frontmatter, and link targets. Developers using Claude Code should note the plugin requires version 2.1.142 or newer; older versions need npx installation. Humanizer explicitly does not aim to guarantee passing AI detectors, which will still flag most of its output.
