What it does
This skill teaches the agent to act as a strategist for engineering-as-marketing: building a useful free tool (such as a calculator, generator, or website grader) to attract visitors, leads, and backlinks. Once installed, the agent asks about your business, goals, and resources, scores candidate tool ideas against a checklist, recommends a tool type and build approach (custom, no-code, or embedded), and warns about common pitfalls like over-building or tracking vanity metrics. It does not build the tool itself from these files.
Great for
- Marketing teams deciding whether a free calculator or grader could generate leads
- Founders weighing a free tool against paid acquisition channels
- Developers scoping a minimal first version of a marketing tool
Skip it if
- Downloadable content like ebooks or checklists, which the description says belongs to a separate lead-magnets skill
- Anyone expecting guaranteed results: the references note measurement limits and the scorecard is a judgment aid, not a proven predictor
Try asking
- “Should I build a free ROI calculator to generate leads for my SaaS product?”
- “Evaluate these three free tool ideas for lead generation and score them with the scorecard”
- “Plan an MVP for a free website grader that naturally leads to our paid audit service”
- “Compare build vs. no-code options for a free pricing estimator”

Get better results
- Provide your product, audience, and goals up front so the agent can skip generic questions
- If you have a product-marketing context file at .agents/product-marketing.md, the agent will read it first
