--- name: derivatives-concept-plain-language-explainer description: "Translates a complex derivatives concept (margin call, futures rollover, options expiration, contango, assignment, etc.) into a clear, jargon-free explanation for retail customers — structured as a one-line definition, plain-language body, concrete everyday analogy, worked numeric example, common misunderstanding, and what-to-do-next guidance. Use when a support rep, educator, or content writer needs to explain a derivatives term to a customer without financial background." argument-hint: "[derivatives-term] [audience-level]" allowed-tools: ["Read"] --- # Derivatives Concept Plain-Language Explainer ## Purpose Turn a single dense derivatives concept into a customer-ready explanation that a retail investor with no finance background can actually understand — replacing jargon with plain words, one concrete analogy, and a worked example. Solves the recurring problem of support reps and educators rewriting the same complex concepts from scratch, inconsistently, under time pressure. ## When to Use Invoke this skill when the user asks to: - Explain a derivatives term (margin call, rollover, expiration, assignment, contango, theta decay) to a customer - Rewrite a compliance- or exchange-worded definition into plain language - Answer a support ticket that hinges on a customer not understanding a derivatives mechanic - Build a help-center article or FAQ entry for an options or futures concept - Prepare a script or talking points for a CX call about margin, exercise, or expiration - Create onboarding content that demystifies a derivatives feature before a customer enables it ## Inputs Required Before starting, collect: - **Concept to explain**: The specific derivatives term or mechanic (e.g., "margin call on a short options position") - **Audience level**: Complete beginner / Has traded stocks but not derivatives / Has traded options basics - **Product context**: The instrument this applies to — equity options, index options, futures, crypto perps, etc. - **Delivery channel**: Support-ticket reply / Help-center article / Call script / Chat message - **Regulatory sensitivity**: Whether the explanation must avoid anything that could read as advice or a recommendation - **Reading length target**: Short (under 150 words) / Standard (150–300) / In-depth (300–500) If audience level is unspecified, default to "Has traded stocks but not derivatives." If regulatory sensitivity is unspecified, treat the explanation as customer-facing and educational only — never phrase anything as a recommendation to act. ## Instructions ### Step 1: Pin Down the Exact Concept Confirm precisely what is being explained. Many derivatives terms have narrower meanings than they appear: - "Expiration" for a buyer (option can expire worthless) differs from "expiration" for a seller (assignment risk) - "Margin call" on futures (maintenance margin shortfall) differs from a "margin call" on a short options position - "Rollover" can mean rolling a futures contract forward or rolling an options position to a new strike/expiry Restate the concept in one internal sentence before writing, and anchor the explanation to the customer's likely position (buyer vs. seller, long vs. short) based on product context. ### Step 2: Write the One-Line Definition Produce a single sentence a customer could read and immediately grasp. Rules: - No more than 25 words - No undefined jargon — if a term must appear, it gets defined in the same sentence - Lead with what it *means for the customer*, not the textbook mechanic Bad: "A margin call is a broker demand for additional collateral when equity falls below maintenance requirements." Good: "A margin call is a request to add money to your account because a position has lost enough value that your current funds no longer cover it." ### Step 3: Write the Plain-Language Body Explain the mechanic in 2–4 short paragraphs using these constraints: - **Replace every piece of jargon** the first time it's unavoidable, define it in parentheses in plain words - **Use "you" and "your"** — make it about the customer's account and money - **Explain the *why*, not just the *what*** — customers accept mechanics they understand the reason for - **Sentence length under 20 words** on average; break compound ideas into separate sentences - Ban these words unless immediately defined: notional, intrinsic value, extrinsic value, basis, roll yield, delta, gamma, theta, vega, mark-to-market ### Step 4: Add One Concrete Everyday Analogy Provide a single analogy from ordinary life that maps cleanly to the mechanic. Requirements: - Only ONE analogy — multiple analogies confuse more than they clarify - The analogy must map on at least two dimensions (not just "it's like a bet") - Explicitly state where the analogy breaks down, in one sentence, so the customer doesn't over-extend it Example for options expiration: a movie ticket for a specific showtime — it grants a right (to see the film) that must be used by a deadline, and becomes worthless afterward; where it breaks down: unlike a ticket, an option can be sold to someone else before the deadline. ### Step 5: Add a Worked Numeric Example Walk through one simple, round-numbered scenario showing the concept in action: - Use clean numbers (multiples of 10 or 100) so the arithmetic is trivial to follow - Show the starting state, the trigger event, and the outcome in the customer's account - State the dollar effect explicitly — customers understand money movements better than percentages - Label it clearly as an illustrative example, not real market conditions ### Step 6: Name the Common Misunderstanding State the single most frequent way customers misread this concept, then correct it in one or two sentences. This preempts the follow-up ticket. Frame as "A common mix-up: ..." then the correction. ### Step 7: Give What-to-Do-Next Guidance Close with practical, non-advisory next steps: - What the customer can *check* or *monitor* in their account - What generally happens automatically vs. what requires action from them - If regulatory sensitivity is flagged, phrase everything as "here's how it works" — never "you should" — and include a one-line pointer to contact support or consult a licensed professional for decisions ## Output Format - **Structure**: Six labeled sections in fixed order - **Length**: Match the requested reading target; default 150–300 words - **Format**: Short prose paragraphs with clear section labels; the worked example may use a simple 3-line before/trigger/after layout - **Sections**: One-Line Definition → What It Actually Means → An Everyday Analogy → A Simple Example → Common Mix-Up → What This Means for You - **Tone**: Warm, patient, and confident — like a knowledgeable friend explaining something over coffee, never condescending, never lecturing ## Quality Checklist Before delivering output, verify: - [ ] The one-line definition is 25 words or fewer and contains no undefined jargon - [ ] Every banned-list term (notional, delta, theta, mark-to-market, etc.) is either absent or defined in plain words at first use - [ ] Exactly one analogy is used, and its breakdown point is stated - [ ] The worked example uses round numbers and states a specific dollar outcome - [ ] A "common mix-up" is named and corrected - [ ] If regulatory sensitivity was flagged, no sentence phrases an action as a recommendation ("you should," "the best move is") ## Notes - The single biggest failure mode is defining jargon with more jargon — read the draft as if you'd never opened a brokerage account. - Buyer-side and seller-side explanations of the same term (expiration, assignment, margin) often need to be written separately; if the customer's position is ambiguous, cover both briefly rather than guessing. - For futures concepts like contango or rollover, the everyday analogy is doing most of the work — spend extra care making it map cleanly, since these have no equity-market equivalent most customers already know. - Keep the worked example's numbers deliberately unrealistic-but-clean (e.g., a $100 option, a $10 move) so no customer mistakes it for a live quote or price target. --- ## How to use this skill This file is a Claude Code skill in [Anthropic's standard format](https://docs.anthropic.com/en/docs/claude-code/skills) — markdown with YAML frontmatter at the top. **Installing in Claude Code:** - `~/.claude/skills//SKILL.md` — auto-loads in every session anywhere on your machine (recommended for skills you'll use across multiple projects) - `/.claude/skills//SKILL.md` — auto-loads only when working in that project (recommended for project-specific skills) Restart Claude Code or open a new session to register. **Using in Claude.ai, ChatGPT, Gemini, or other AI tools:** 1.
