The specialist skill for judging quality, not just volume. Most "which channel is best" answers get the wrong channel because they look at sessions or even conversion rate in isolation. The right answer is a matrix.
Channel And Funnel Quality is a community-contributed Claude Code skill in the conversion sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/channel-and-funnel-quality/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when comparing marketing channels, reading a conversion funnel, or deciding where to invest. Covers volume × engagement × conversion as a matrix, vanity-traffic detection, expected step drop-off by funnel type, cohort decomposition, and mix-shift (Simpson's paradox) handling.
