Analyze assertion quality, depth, variety, and false confidence in existing tests. ALWAYS USE when asked about weak, shallow, trivial, always-true, self-referential, assertion-free, presence/truthiness-only, or insufficiently diverse assertions, including MSTest, Jest, pytest, and Go. DO NOT USE for direct fixes: writing-mstest-tests owns supplied MSTest assertions; code-testing owns new cases.

if [ -e ~/.agents/skills/'assertion-quality' ] || [ -L ~/.agents/skills/'assertion-quality' ]; then echo 'A skill folder named assertion-quality already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/managedcode/dotnet-skills' "$d" && git -C "$d" checkout --quiet 'b461d186f21dcab31bc4b1cf48f7cced8ac61780' -- 'external-sources/upstreams/dotnet-skills/plugins/dotnet-test/skills/assertion-quality' && mkdir -p ~/.agents/skills && cp -R "$d"/'external-sources/upstreams/dotnet-skills/plugins/dotnet-test/skills/assertion-quality' ~/.agents/skills/'assertion-quality' && 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/'assertion-quality' ~/.claude/skills/'assertion-quality' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
