Build reusable product positioning and messaging context

Product Marketing Context creates and maintains a single reusable document at .agents/product-marketing-context.md that captures a product's foundational positioning and messaging, so other marketing skills can reference it instead of the user re-explaining ICP, messaging, and product basics on every task. If the file already exists, it reads and summarizes what is captured and only asks about the sections the user wants updated. If it does not exist, it offers to auto-draft a V1 by studying the codebase - README, landing pages, marketing copy, package.json, existing docs - for the user to review and correct, or to walk through each section conversationally from scratch, one at a time, pushing for verbatim customer language over polished descriptions because exact phrases reflect how customers actually think and speak.

Use it at the start of a marketing project, before more specialized marketing skills, whenever the user wants a reusable positioning and audience context file instead of repeating the same product background across tasks.

Input is the codebase (for auto-drafting) or conversational answers across twelve sections: product overview, target audience, B2B personas (User, Champion, Decision Maker, Financial Buyer, Technical Influencer), problems and pain points, competitive landscape (direct, secondary, and indirect competitors), differentiation, objections and anti-personas, switching dynamics (the JTBD Four Forces: Push, Pull, Habit, Anxiety), customer language, brand voice, proof points, and goals. Output is a structured Markdown document with a fixed template - headings, tables for personas/objections/glossary/value themes, and verbatim-quote fields for how customers describe the problem and the product - saved to .agents/product-marketing-context.md after the user confirms it. Not every section applies to every product - personas, for instance, are typically skipped for B2C.

None beyond the local file system and whatever marketing skills later read .agents/product-marketing-context.md automatically; the document is meant to be re-run anytime via a /product-marketing-context command to keep it current, and the skill also checks the agent's local skill directory for an older copy of the file to offer moving into .agents/ if one is found there instead.

Marketers and founders who are about to run several marketing tasks - copy, campaigns, positioning work - on the same product and want the ICP, competitive landscape, and customer language captured once and correctly, in customers' own words where possible, rather than re-derived or re-explained for every individual request.
