What problem does it solve? Solo developers often build good tools but struggle to position and explain them to the right audience. This Skill provides a lightweight marketing framework for planning launches, writing landing-page and email copy, defining a brand voice, and positioning a product against competitors — scoped to what one person can actually execute, without agency-scale overhead. ## Core Features & Use Cases - Positioning & Market Context: Lock a core benefit, positioning statement, campaign angle, and a lightweight competitive scan before writing any copy, with an escalation path to a full competitor-research method for bigger decisions. - Brand Voice Extraction: Derive a reusable VOICE PROFILE from 5-20 real writing samples (READMEs, posts, changelogs) with do/don't vocabulary lists and before/after rewrites, plus an interview-based fallback for brand-new projects. - Copy Production & Review Gate: Produce landing pages, email sequences, social posts, and ad variants from structured templates, then pass everything through a mandatory review checklist with hard bans on hype words and fabricated social proof. - Use Case: You are launching an open-source CLI tool and need a landing page, a launch email, and announcement posts. The Skill locks your positioning first, derives your voice from your README, then drafts each deliverable consistently. ## Quick Start Help me plan the launch of my open-source tool, including a positioning statement, landing page copy, and a launch email.
