Concept Explainer
Clear AND accurate — builds from what you know, one concrete anchor (and where it breaks), progressive depth, flags every simplification.

What it does
Explains a technical concept calibrated to the audience: builds from a concept they already know, leads with the plain-language core idea, uses a concrete anchor/analogy (and names where it breaks down), and adds depth progressively. Stays honest — accurate over cute, flags each simplification's limits so it doesn't become a misconception, and won't confidently teach something it's unsure of.
Example uses
Explain OAuth to a designer
A non-engineer teammate needs a correct mental model of a technical concept without being talked down to.
Explain OAuth 2.0 to a product designer who understands logins and sessions but has never read a spec. Use one concrete analogy, tell her exactly where the analogy breaks down, and limit the jargon to terms she will actually hear in meetings.Build a correct mental model
You keep running into a term and want a real understanding that builds on what you already know, not a marketing definition.
I'm a backend developer comfortable with SQL and Redis. Explain what a vector database actually is, building from what I already know. Start with the one-sentence core idea, then add depth progressively, and flag every simplification you make along the way.ELI5 without being wrong
You want a simple explanation now that you will not have to unlearn later.
ELI5 how HTTPS keeps my data private, then add one more layer of depth for someone who knows what a server is. Tell me explicitly which parts you simplified and why those details don't matter for everyday use.Install

name: concept-explainer
description: Explain a technical concept clearly and correctly, calibrated to the audience's level. Use when learning something new, explaining a concept to a teammate, or asked "explain X", "ELI5 Y", "help me understand Z". Builds from what they know, uses concrete anchors, stays accurate.

# Concept Explainer
A good explanation meets people where they are and builds a correct mental model — not a
simplification so lossy it's wrong. Clear AND accurate; if you must trade, flag the simplification.
## Calibrate to the audience
- Ask or infer their level: total beginner, knows-adjacent-things, or expert wanting the crux.
The same concept is explained very differently to each — pitching wrong wastes both of you.
- **Build from what they already know.** Connect the new idea to a concept they have. Learning
is attaching new things to existing hooks; find the hook.
## Build understanding
- **Lead with the core idea** in plain language — the one-sentence "what it really is" — before
any jargon. Then introduce terms, defining each as you go.
- **Concrete anchor**: an analogy or a real example that captures the essence. A good analogy
does most of the work — but say where it breaks down (every analogy leaks; an unqualified one
becomes a misconception).
- **Progressive depth**: simple correct model first, then add the nuance. Don't open with the
exception-riddled full truth; don't stop at a model so simple it's false.
- **The "why it matters"**: when/why you'd actually use or care about this — context makes it stick.
## Stay honest
- **Accurate over cute.** A memorable analogy that teaches a wrong model is a net negative —
they'll have to unlearn it. Correct-but-plain beats catchy-but-wrong.
- When you simplify, SAY so ("roughly — there's more nuance, but this is the useful 90%").
- If you're not sure it's correct, don't confidently teach it. Say what you're unsure of.
## Rules
- Meet their level and build from a known hook; an explanation over/under their head fails.
- Accurate first; flag every simplification's limits so it doesn't become a misconception.
- Concrete anchors and progressive depth over a wall of precise jargon.
## Output
The explanation, pitched to the level: core idea → anchor/analogy (with its limits) → depth as
needed → why it matters. Check for understanding or offer the next layer if they want more.
