The hardest part of learning is that you can't see your own gaps — especially the unknown-unknowns, the things you don't even know you're missing. So people re-study what they already know (comfortable) and skip the holes (invisible). This maps the territory of a subject against what you know, surfaces the gaps you can't see, and tells you which ones actually matter for your goal — so your learning aims at the holes.
Knowledge Gap Map is a community-contributed Claude Code skill in the knowledge-mgmt sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/knowledge-gap-map/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when asked what don't I know about X, find my knowledge gaps, what should I learn next in, or map my understanding of. Produces a picture of the subject's territory, what you already know vs the gaps, the dangerous unknown-unknowns (things you don't know you're missing), which gaps matter most for your goal, and a prioritized learn-next list — so effort goes where it counts.
The Knowledge Gap Map Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 178,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

SKILL.md from the source repository to ~/.claude/skills/knowledge-gap-map/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Knowledge Gap Map is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.
