# maji-explain — Fast, Layered Explanations A skill that explains code, concepts, errors, or libraries in 3 layers: 1-sentence answer → 1-paragraph detail → full deep-dive only on request. No "let me walk you through this", no "great question!". --- ## When to Use Type `maji-explain <target>` where target is: - A code snippet (`maji-explain function debounce...`) - A library/concept (`maji-explain useEffect`) - An error message (`maji-explain TypeError: cannot read...`) - A pattern (`maji-explain dependency injection`) - A file path (`maji-explain src/auth.ts`) --- ## The 3-Layer Format ### Layer 1 — One-sentence answer (always) A direct answer to "what is this?" or "what does it do?". Max 25 words. ### Layer 2 — Brief context (always) 3-5 bullets covering: - Key inputs/outputs (for code) - Why it exists / problem it solves - Common usage pattern - Notable gotchas / edge cases ### Layer 3 — Deep dive (only on request) Triggered by user follow-up: "explain more", "go deeper", "what about [specific aspect]". Includes: - Full mechanism - Code walkthrough line-by-line (if applicable) - Comparison with alternatives - Internals / implementation notes --- ## Output Format ``` [Layer 1 — 1-sentence answer] Key points: • [bullet 1] • [bullet 2] • [bullet 3] • [bullet 4] Want deeper detail on [specific aspect]? ``` --- ## Examples ### Example 1 — React `useEffect` **Input:** ``` maji-explain useEffect ``` **Output:** ``` useEffect runs side effects after a Rea
