calculator-design

Designing interactive calculators (ROI calculators, pricing estimators, savings projections, mortgage calculators, custom assessments) that deliver real decision-support value while serving as lead magnets and qualified-traffic generators. Honest about vanity-calculator (no real value), lead-trap (hides the answer behind email), and transparent-decision-tool (gives the result and earns the email through tiered value) patterns. Triggers on calculator, ROI calculator, pricing estimator, savings calculator, custom calculator, interactive tool, decision tool, financial calculator. Also triggers when an audience needs a calculation-driven lead magnet, when a vanity calculator is producing leads but no qualified ones, or when a calculator is being scoped for the first time.

Quality

Content

35%

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

This skill provides a strong conceptual framework for calculator design with clear opinions and useful distinctions (vanity vs lead-trap vs transparent-decision-tool). However, it is significantly over-verbose, repeating core concepts across multiple sections and explaining things Claude already knows. It lacks concrete, executable artifacts (templates, copy examples, implementation checklists) that would make it truly actionable, and the referenced bundle files don't exist.

Suggestions

Cut content by 40-50%: eliminate the repeated explanations of vanity/lead-trap/transparent-tool across sections, remove the closing section that restates everything, and trim explanations of basic concepts (input types, what ROI means).

Add concrete artifacts: include a calculator design brief template, a sample methodology disclosure page, and a specific tiered-value mapping worksheet that Claude can adapt and fill in.

Add validation checkpoints to the 12-consideration framework: after which steps should the designer validate with stakeholders, test with users, or check methodology defensibility?

Either provide the referenced bundle files or consolidate the most critical reference content (e.g., the decision tree and methodology templates) inline in a compact format.

Conciseness

Extremely verbose at ~300+ lines. Extensively explains concepts Claude already understands (what a vanity calculator is, what PDFs are, what ROI means, what input types exist). The same points about transparency, lead-traps, and vanity calculators are repeated across multiple sections (keystone framing, anti-patterns, closing, framework). The closing section restates nearly everything already covered. Significant token waste through redundancy and over-explanation.

1 / 3

Actionability

Provides a clear conceptual framework (the 3 calculator types, the 12-consideration checklist, tiered value structure) and a worked B2B SaaS example. However, there are no executable code snippets, no concrete templates, no specific copy examples, and no step-by-step implementation instructions. The guidance is principled and opinionated but remains at the strategic/conceptual level rather than providing copy-paste-ready artifacts.

2 / 3

Workflow Clarity

The 12-consideration framework provides a clear checklist for design/audit, and the tiered-value structure gives a sequenced approach. However, there are no explicit validation checkpoints, no feedback loops for iterating on calculator quality, and no step-by-step process for going from 'decide to build' to 'ship and measure.' The failure-mode section lists symptoms but doesn't provide a structured diagnostic workflow.

2 / 3

Progressive Disclosure

References 9 detailed reference files with clear descriptions and relative paths, which is good structure. However, no bundle files are provided, so the references are unresolvable. The main SKILL.md itself contains substantial inline content that could have been pushed to references (anti-patterns, failure modes, input design details), making the top-level document much longer than necessary. The overview-to-detail split is present but the overview is too heavy.

Description

100%

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

This is a strong, well-crafted description that clearly defines a specific niche (interactive calculator design for lead generation), lists concrete actions and deliverables, and provides comprehensive trigger terms covering both keyword matches and scenario-based triggers. The description is detailed without being padded, uses third person voice appropriately, and would be easily distinguishable from other skills in a large skill library.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions and outputs: ROI calculators, pricing estimators, savings projections, mortgage calculators, custom assessments. Also names specific patterns (vanity-calculator, lead-trap, transparent-decision-tool) which add concrete detail.

3 / 3

Completeness

Clearly answers both 'what' (designing interactive calculators with specific patterns and value frameworks) and 'when' (explicit 'Triggers on...' clause plus additional scenario-based triggers like 'when a calculator is being scoped for the first time').

3 / 3

Trigger Term Quality

Excellent coverage of natural trigger terms users would say: 'calculator', 'ROI calculator', 'pricing estimator', 'savings calculator', 'interactive tool', 'decision tool', 'financial calculator', 'lead magnet'. Also includes scenario-based triggers like 'vanity calculator is producing leads but no qualified ones'.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive niche combining interactive calculator design with lead generation strategy. The specific calculator types, the named patterns (vanity-calculator, lead-trap, transparent-decision-tool), and the marketing/lead-gen framing make it very unlikely to conflict with generic coding or marketing skills.
