What it does

Knowledge Gap Map is an agent skill from mohitagw15856/pm-claude-skills. 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…

Its SKILL.md is about 980 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

When your agent uses it

  • Asked what dont I know about X
  • Find my knowledge gaps
  • What should I learn next in
  • Map my understanding of

Example prompts

  • “t know about a subject — including the gaps you can”
  • “t know you”
  • “/knowledge-gap-map”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Lay out the whole territory. Sketch what the subject actually spans — you can only see gaps against a map of the whole.
  2. Compare to what you know. Split the territory into solid vs. shaky vs. missing, using the person's self-assessment plus a few probing…
  3. Surface unknown-unknowns. The high-value move: name important areas the person didn't mention because they didn't know to — the invisible…
  4. Prioritize by goal. Not every gap is worth filling — flag the ones that actually matter for their purpose, and the ones they can safely…
  5. Order the learn-next list. Sequence the priority gaps (respecting dependencies) so learning targets the holes efficiently.

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Knowledge Gap Map loads about 981 tokens when it runs. Until then it costs about 139 tokens; SKILL.md has 493 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~139
When it runs · the whole SKILL.md, loaded when a task matches
~981

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
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.

Knowledge-Gap Map

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.

What This Skill Produces

  • The territory — the map of what the subject actually covers (the whole landscape, so gaps become visible)
  • Know vs. don't-know — a split of what you've got vs. where the holes are, based on your self-assessment and probing
  • The unknown-unknowns — the important things you didn't know you were missing (the dangerous, invisible gaps)
  • Gap priority — which gaps matter most for your goal (not all gaps are worth filling)
  • A learn-next list — the prioritized holes to target, in order

Required Inputs

Ask for these if not provided:

  • 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

Framework: Map The Territory, Find The Holes

  1. Lay out the whole territory. Sketch what the subject actually spans — you can only see gaps against a map of the whole.
  2. Compare to what you know. Split the territory into solid vs. shaky vs. missing, using the person's self-assessment plus a few probing questions.
  3. Surface unknown-unknowns. The high-value move: name important areas the person didn't mention because they didn't know to — the invisible gaps.
  4. Prioritize by goal. Not every gap is worth filling — flag the ones that actually matter for their purpose, and the ones they can safely skip.
  5. Order the learn-next list. Sequence the priority gaps (respecting dependencies) so learning targets the holes efficiently.

Output Format

Mapping your knowledge of: [subject] · for [goal]

The territory: [the areas the subject covers]. You've got: [solid areas]. Shaky: [wobbly areas]. ⚠️ Gaps you didn't know you had: [important unknown-unknowns]. Matters for your goal: [the gaps worth filling] · Can skip: [not needed for you]. Learn next (in order): [prioritized holes].

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
  • Produces an ordered learn-next list respecting dependencies

Anti-Patterns

  • 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.

Example Trigger Phrases

  • "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."
