Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Verify that a watermark-removal or "humanizer" step actually removed a statistical text watermark, by measuring a sample whose key the user holds. Use after any tool, script or service claims to have cleaned a text, or when the user asks whether such a tool works, which one to trust, or how to test one. Reports a detector score against fixed thresholds plus what the run cost in meaning, facts, verbatim overlap and length. This skill only measures and never removes a mark.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'verify-watermark-removal' ] || [ -L ~/.agents/skills/'verify-watermark-removal' ]; then echo 'A skill folder named verify-watermark-removal already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/davepoon/buildwithclaude' "$d" && git -C "$d" checkout --quiet '941b335e8e2d748d9855f77c0fc0aaec924b75b9' -- 'plugins/all-skills/skills/verify-watermark-removal' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/all-skills/skills/verify-watermark-removal' ~/.agents/skills/'verify-watermark-removal' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'verify-watermark-removal' ~/.claude/skills/'verify-watermark-removal' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
