Analyzes test suites to identify redundant and duplicate test cases using coverage analysis, semantic similarity, and execution results. Use this skill when you need to reduce test suite size, identify redundant tests, optimize test execution time, analyze test coverage overlap, find tests with identical behavior, or improve test suite maintainability. Triggers when users ask to deduplicate tests, find redundant test cases, reduce test suite size, identify duplicate tests, or optimize test cove…

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/'test-deduplicator' ] || [ -L ~/.agents/skills/'test-deduplicator' ]; then echo 'A skill folder named test-deduplicator already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/ArabelaTso/Skills-4-SE' "$d" && git -C "$d" checkout --quiet '4f38503747e0617504bce5329283ef837d375c09' -- 'skills/test-deduplicator' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/test-deduplicator' ~/.agents/skills/'test-deduplicator' && 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/'test-deduplicator' ~/.claude/skills/'test-deduplicator' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
