copywriting-prose-creator

Codifies how a person or brand writes by capturing prose mechanics — lexicon, syntax, rhythm, structure, and signature moves — independent of emotional tone. The single output is PROSE.md, a brand-specific guide treating prose as reproducible craft a forensic linguist could measure on a page: sentence length, clause depth, parallelism, and voice markers. The guiding slogan is "tone is the music, prose is the score," with tone handled by a separate sibling skill so that two brands with identical tones can still have non-interchangeable prose.

Three modes are offered. BUILD creates a fresh PROSE.md from optional SOUL.md and TONE.md inputs plus a discovery interview. ADAPT ports an existing PROSE.md to a new channel grouping. AUDIT analyzes a content corpus to surface current prose patterns before codification, using parallel sub-agents when the corpus exceeds 50 pieces. Channels are treated as four generic groupings — long-form articles, social posts, email and newsletter, and marketing copy — with platform-specific quirks deliberately left to downstream writer skills. The persona is a prose engineer, and ultrathink reasoning is mandated for every BUILD and ADAPT invocation to avoid flattening into a generic LLM-default register.

The BUILD workflow detects inputs in the working directory (including ./brand, ./content, ./docs), surfacing missing SOUL.md or TONE.md and offering to invoke the sibling tone skill or capture archetype and tone minimally inline. A discovery interview gathers fields such as brand mission, category posture, audience expertise, author archetype, per-channel objectives, distribution channels, constraints, and cultural context. Category detection matches the brand to one of 11 covered categories (B2B SaaS, B2C, consumer/DTC, NGO, consulting, product-led, industry, community, personal branding, politics, internal comms), loading category-specific defaults; brands outside those categories trigger delegated deep research. The doc is explicit about what the skill is not for — writing actual content, removing AI patterns, tone decisions, hooks, or CTAs all route to other named skills.
