options-payoff

Generate an interactive options payoff curve chart with dynamic parameter controls. Use this skill whenever the user shares an options position screenshot, describes an options strategy, or asks to visualize how an options trade makes or loses money. Triggers include: any mention of butterfly, spread (vertical/calendar/diagonal/ratio), straddle, strangle, condor, covered call, protective put, iron condor, or any multi-leg options structure. Also triggers when a user pastes strike prices, premiums, expiry dates, or says things like "show me the payoff", "draw the P&L curve", "what does this trade look like", or uploads a screenshot from a broker (IBKR, TastyTrade, Robinhood, etc). Always use this skill even if the user only provides partial info — extract what you can and use defaults for the rest.

Quality

Content

78%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is well-structured with a clear five-step workflow, concrete formulas and specs, and excellent progressive disclosure via two real reference files. Its main weaknesses are minor redundancy between inline formulas and the strategies reference, stub placeholders in the code template, and the absence of explicit validation checkpoints.

Suggestions

Remove the payoff formulas duplicated in Step 3 that already appear in references/strategies.md, replacing them with a pointer to keep SKILL.md lean.

Replace the placeholder stubs in the JS code template (e.g., /* standard BS call */) with a direct instruction to copy the implementations from references/bs_code.md, or inline the full functions.

Add a lightweight verification checkpoint after Step 3 or Step 4, e.g. sanity-check that breakevens lie within the strike range and that max loss/profit are finite before rendering.

Dimension	Reasoning	Score
Conciseness	The body is largely lean and assumes Claude's competence (no preamble explaining what options or Black-Scholes are), but payoff formulas are restated inline in Step 3 while also appearing in references/strategies.md, creating minor redundancy.	4 / 5
Actionability	Provides concrete Black-Scholes formulas, a JS code template, specific slider ranges ("IV % (5–80%, step 0.5)"), and detailed chart specs, but the inline JS template uses placeholder stubs (/* Horner approximation /, / standard BS call */) that require the reference file to be fully executable.	4 / 5
Workflow Clarity	Five clearly sequenced steps (extract, identify, compute, render, respond) with specific sub-instructions, but there are no explicit validation or verification checkpoints for the computed payoffs or rendered widget despite a multi-step compute-and-render flow.	4 / 5
Progressive Disclosure	SKILL.md is a clear overview that delegates detail to two real, one-level-deep reference files (references/strategies.md, references/bs_code.md), both explicitly signaled in a dedicated "Reference Files" section with clear navigation.	5 / 5

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is exemplary: it states concrete capabilities, provides comprehensive natural trigger terms covering strategy names, user phrases, and brokers, and explicitly answers both what the skill does and when to use it. It is highly distinctive within a clear niche.

Dimension	Reasoning	Score
Specificity	"Generate an interactive options payoff curve chart with dynamic parameter controls" and "visualize how an options trade makes or loses money" list multiple concrete actions (chart generation, dynamic controls, payoff visualization) with comprehensive coverage.	5 / 5
Completeness	Explicitly answers "what" (generate an interactive options payoff curve chart with dynamic parameter controls) and "when" ("Use this skill whenever the user shares an options position screenshot, describes an options strategy... Triggers include...") with concrete trigger phrases.	5 / 5
Trigger Term Quality	Comprehensive natural terms including strategy names (butterfly, spread, straddle, strangle, condor), user phrases ("show me the payoff", "draw the P&L curve", "what does this trade look like"), and broker names (IBKR, TastyTrade, Robinhood) covering synonyms and variations.	5 / 5
Distinctiveness Conflict Risk	Occupies a clear niche (options payoff visualization) with distinct, specialized trigger terms that are unlikely to fire for unrelated skills; minimal conflict risk.	5 / 5
	Total	20 / 20 Passed
