QQRD Watermark Embedding MATLAB Implementation
100 / 100 · Low risk
Fine to try.
Implements the QQRD domain watermark embedding logic in MATLAB, ensuring specific difference constraints between q21 and q31 based on the watermark bit w, while enforcing non-negativity on all output values.

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.
Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'qqrd-watermark-embedding-matlab-implementation' ] || [ -L ~/.agents/skills/'qqrd-watermark-embedding-matlab-implementation' ]; then echo 'A skill folder named qqrd-watermark-embedding-matlab-implementation already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/ECNU-ICALK/AutoSkill' "$d" && git -C "$d" checkout --quiet '94c47ca488d4ba4117d20272e66d49b9877e68cf' -- 'SkillBank/ConvSkill/english_gpt3.5_8/qqrd-watermark-embedding-matlab-implementation' && mkdir -p ~/.agents/skills && cp -R "$d"/'SkillBank/ConvSkill/english_gpt3.5_8/qqrd-watermark-embedding-matlab-implementation' ~/.agents/skills/'qqrd-watermark-embedding-matlab-implementation' && 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/'qqrd-watermark-embedding-matlab-implementation' ~/.claude/skills/'qqrd-watermark-embedding-matlab-implementation' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
