100 / 100 · Low risk

Fine to try.

By ECNU-ICALK/AutoSkill (GitHub) · other · 613 stars · scanned at commit 94c47ca

Implements signed 64-bit division functions (e.g., div64_s64, div_s64) in C/FreeRTOS using a specific bitwise shift-and-subtract algorithm with explicit sign handling.

Works with any agent that supports SKILL.md skills.

Install

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

if [ -e ~/.agents/skills/'implement-64-bit-signed-division-using-bitwise-operations' ] || [ -L ~/.agents/skills/'implement-64-bit-signed-division-using-bitwise-operations' ]; then echo 'A skill folder named implement-64-bit-signed-division-using-bitwise-operations 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 "$d" checkout --quiet '94c47ca488d4ba4117d20272e66d49b9877e68cf' -- 'SkillBank/ConvSkill/english_gpt3.5_8/implement-64-bit-signed-division-using-bitwise-operations' && mkdir -p ~/.agents/skills && cp -R "$d"/'SkillBank/ConvSkill/english_gpt3.5_8/implement-64-bit-signed-division-using-bitwise-operations' ~/.agents/skills/'implement-64-bit-signed-division-using-bitwise-operations' && 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/'implement-64-bit-signed-division-using-bitwise-operations' ~/.claude/skills/'implement-64-bit-signed-division-using-bitwise-operations' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
