## What it does

The skill looks at why a book's marketing copy is not working and rewrites it. It works through six states: no copy exists yet, the description summarizes instead of selling, it signals the wrong genre, it sounds generic, it ignores platform conventions, or the tagline does not stick. Each state comes with questions, a checklist and a set of fixes.

You get four deliverables: a back-of-book blurb, a store description, a tagline and a query pitch. Genre matters here. A wonder story should promise discovery, a thriller should promise stakes and tension, a romance should promise emotional connection. If the genre is unclear, the author suggests running the genre-conventions skill first.

The blurb structure is fixed: a hook of 25–50 words, a setup of 50–75 words, then a stakes question. The first sentence has to stop a browser, and the copy should end on tension rather than resolution. It runs in Claude, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode.

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/jwynia/agent-skills/tree/HEAD/skills/creative/fiction/application/book-marketing/SKILL.md

## When to use it
- figure out why a book description is not converting
- write a blurb from scratch when only the manuscript exists
- turn a plot summary into sales copy
- fit a description to a specific platform's conventions
- come up with a tagline readers remember after one pass

## Example prompts
- diagnose my book description and tell me what's wrong
- write a back-cover blurb from this manuscript
- draft a tagline for a thriller and a query pitch for an agent

# Book Marketing: Diagnostic and Generative Skill

You diagnose book marketing copy problems and generate effective marketing copy across platforms. Your role is to help authors translate their books into compelling marketing materials.

## Core Principle

**Marketing copy promises an experience. It doesn't summarize a story—it creates desire for one.**

Writers who excel at novels often struggle with descriptions because they're different skills. A 200-word blurb must make readers feel they'll miss out by not buying. It's sales copy, not synopsis.

## The Marketing States

### State M1: No Marketing Copy Exists

**Symptoms:** Book is complete but no blurb, description, or pitch exists. Author doesn't know where to start. Blank page paralysis.

**Key Questions:**
- What elemental genre(s) does this book deliver?
- What emotional experience should readers expect?
- What are 3-5 comparable titles?
- What makes this book different from those comparables?

**Diagnostic Checklist:**
- [ ] Elemental genre identified
- [ ] Emotional core articulated
- [ ] Stakes can be stated in one sentence
- [ ] At least one comparable title identified

**Interventions:**
- Start with genre identification
- Generate logline first (25-35 words)
- Expand logline to blurb
- Adapt to platforms

### State M2: Copy Summarizes Instead of Sells

**Symptoms:** Description reads like book report. "First X happens, then Y, then Z." No emotional hook. Tells what happens rather than what readers will experience.

**Key Questions:**
- Does the copy promise an experience?
- Is there a hook in the first sentence?
- Do stakes appear within first 50 words?
- Would a reader feel desire or just information?

**Diagnostic Checklist:**
- [ ] First sentence creates curiosity
- [ ] Protagonist introduced with emotional context
- [ ] Conflict is about stakes, not just events
- [ ] Copy ends with question or tension, not resolution

**Interventions:**
- Rewrite opening as hook, not backstory
- Replace plot events with emotional stakes
- Cut anything after the moment of choice
- Add "What will X do when..." structure

### State M3: Copy Signals Wrong Genre

**Symptoms:** Romance described like literary fiction. Thriller copy sounds cozy. Readers expecting one thing, getting another. "Didn't match description" feedback.

**Key Questions:**
