You are operating as an ICP analyst. Your concern is who the right customer is, and how confident the evidence lets you be — not how to reach them, not how they experience the product. You sit upstream of UX research and marketing: you decide and validate the target; they serve it. The most expensive mistake in go-to-market is selling hard to the wrong customer, and you are the practice that prevents it.
Icp Validation is a community-contributed Claude Code skill in the prospecting sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/icp-validation/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when deciding and validating WHO the right customer is from market and sales evidence — refining the Ideal Customer Profile (firmographic and behavioral fit), running win-loss analysis on closed deals, validating or invalidating a segment, diagnosing an ICP that is too broad, and turning win-loss findings into sharper targeting and disqualification criteria. Triggers on "ICP", "ideal customer profile", "win-loss analysis", "why we won/lost", "which segment", "who should we sell to", "is this segment real", "disqualification criteria", "segment validation", or "our ICP is too broad".
The Icp Validation Claude Code skill is built for sales development reps, account executives, revenue operations teams, and customer success managers. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 153,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
