Excel VBA Composite Key Duplicate Prevention

100 / 100 · Low risk

Fine to try.

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

Generates a VBA Worksheet_Change macro to prevent duplicate entries based on two columns (e.g., Company Name and Invoice Value). It triggers on entry in the second column, checks for existing matching pairs, alerts the user with the row number of the duplicate, and clears the new entry.

Works with any agent that supports SKILL.md skills.

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/'excel-vba-composite-key-duplicate-prevention' ] || [ -L ~/.agents/skills/'excel-vba-composite-key-duplicate-prevention' ]; then echo 'A skill folder named excel-vba-composite-key-duplicate-prevention 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 "$d" checkout --quiet '94c47ca488d4ba4117d20272e66d49b9877e68cf' -- 'SkillBank/ConvSkill/english_gpt3.5_8/excel-vba-composite-key-duplicate-prevention' && mkdir -p ~/.agents/skills && cp -R "$d"/'SkillBank/ConvSkill/english_gpt3.5_8/excel-vba-composite-key-duplicate-prevention' ~/.agents/skills/'excel-vba-composite-key-duplicate-prevention' && 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/'excel-vba-composite-key-duplicate-prevention' ~/.claude/skills/'excel-vba-composite-key-duplicate-prevention' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
