Knowledge-Gap Map

Q: How do I know the Knowledge-Gap Map output is good?

The skill verifies itself against its own quality checks: Lays out the full territory so gaps are visible; Splits known/shaky/missing honestly; Surfaces unknown-unknowns (the invisible, important gaps); Prioritizes gaps by the person's actual goal.

Map what you don't know about a subject — including the gaps you can't see — so your learning targets the holes instead of re-covering what you already know. 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.

🗣 Say this to your agent

“What don't I know about personal finance that I should?”“Map my knowledge gaps in machine learning.”“What should I learn next in cooking — where are my holes?”“I know some marketing but not sure what I'm missing.”“Find the gaps in my understanding of this subject.”

What to give it

▸The subject — what you're mapping your knowledge of

▸Your goal — what you need the knowledge for (determines which gaps matter)

▸What you know — your current understanding (to compare against the territory)

▸Where you feel shaky — the gaps you already sense

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓Lays out the full territory so gaps are visible

✓Splits known/shaky/missing honestly

✓Surfaces unknown-unknowns (the invisible, important gaps)

✓Prioritizes gaps by the person's actual goal

✓Produces an ordered learn-next list respecting dependencies

⚠️ What it refuses to do

**Only listing gaps the person already knows** about.

**No map of the territory** to see gaps against.

**Treating all gaps as equally important.**

**Missing the unknown-unknowns** — the whole point.

**A flat list** with no priority or order.
