Use when: "mock service," "stub API," "fake service," "WireMock," "MSW," "Toxiproxy," "test isolation," "dependency management," "stub an external API in CI." Not for: consumer-driven contract verification (Pact, broker) — u…

if [ -e ~/.agents/skills/'service-virtualization' ] || [ -L ~/.agents/skills/'service-virtualization' ]; then echo 'A skill folder named service-virtualization already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/petrkindlmann/qa-skills' "$d" && git -C "$d" checkout --quiet '62434253c2592f27b494609c27f224939c86346d' -- 'skills/service-virtualization' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/service-virtualization' ~/.agents/skills/'service-virtualization' && 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/'service-virtualization' ~/.claude/skills/'service-virtualization' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
