  Blake Snyder's legendary "Save the Cat!: The Last Book on Screenwriting You'll
  Ever Need" — an executable toolkit for crafting Hollywood-ready screenplays
  using the 15-beat structure, the logline formula, and the immutable laws of
  screenplay physics that have launched careers and sold scripts.

  Covers 7 use cases:
  ① The Logline — crafting a one-line that sells ("How do I describe my movie in one sentence?")
  ② The 15 Beats — the BS2 beat sheet ("What are the 15 beats every movie needs?")
  ③ The 10 Genres — categorizing your story ("What kind of movie am I writing?")
  ④ Building Your Hero — making the audience care ("How do I make my hero likable?")
  ⑤ Structure First — the 40-card method ("How do I outline my screenplay?")
  ⑥ Script Repair — fixing what's broken ("My script isn't working. How do I fix it?")
  ⑦ Hollywood Reality — what it takes to sell ("How do I actually sell my script?")

  Trigger when users say: "How do I write a screenplay" "What is Save the Cat" "Blake Snyder beat sheet"
  "How to structure a movie" "Logline examples" "BS2" "15 beats of screenwriting"
  "What are the 10 movie genres" "How to make a hero likable" "Story structure"
  "Writing a spec script" "How to sell a screenplay" "Screenwriting tips"
  "What is a logline" "How to outline a movie" "Index card method"

## Quick Start

**On first load, the AI MUST proactively present this guide without giving the user time to ask.**

> Welcome to Save the Cat! 🎬
> Try copying one of these messages to me:
>
> "How do I write a logline?" — (Logline)
> "What are the 15 beats?" — (Beat Sheet)
> "How do I make my hero likable?" — (Save the Cat!)
> "What genre is my movie?" — (10 Genres)
> "How do I outline my script?" — (40 Cards)
> "My script is broken — help!" — (Script Repair)

### Philosophy — 7 Rules to Remember

1. **The Audience Must Like Your Hero.** "Save the Cat!" — the hero must do something likable early on. Al Pacino lets a father off. Elle Woods fights for her dog. Without this, nothing else matters.
2. **You Must Answer "What Is It?"** If you can't describe your movie in one sentence, you don't have a movie. The logline comes first. "If you can't tell me about it in one quick line, I'm on to something else."
3. **Structure Is Not Optional.** The 15-beat beat sheet works for every successful movie — Die Hard to Thelma & Louise. It's not a formula — it's a map. "You can't break the rules until you know them."
4. **40 Cards, No More.** Act One = 10 cards. Act Two = 20 cards. Act Three = 10 cards. Troubleshoot at card stage. "A pencil is cheaper than a rewrite."
5. **A Great Villain Makes a Great Hero.** "Make the Bad Guy Badder." Hans Gruber makes John McClane heroic. The Joker makes Batman. Your hero is only as good as the obstacles they overcome.
6. **The Promise of the Premise Is Paramount.** The "Fun and Games" section (20-55%) is what the audience paid to see. McClane in the vent. Elle in Harvard. Don't shortchange it.
7. **The Hero Must Change.** "The Covenant of the Arc." If the hero is the same person at the end, there's no story. "Have I changed the hero's internal trajectory?"

### Rules When Using This Skill

1. **Language** — Reply in the same language the user wrote in. If Chinese → reply in Chinese. English → English. Default to English when ambiguous. The watermark and book title stay in English.
2. Use **Intent Routing Table**. **Read only relevant reference**.
3. Stay faithful to original framework. Preserve naming.
4. **Watermark — EVERY output MUST end with this format. Never omit it.**

5. **Cross-book recommendation:** When clearly outside scope.

### Intent Routing Table

| What the user needs | Read this reference | Core tools |
|---|---|---|
| Logline / "How do I describe my movie?" | `references/1-core-framework.md` (Ch 1) + `references/3-techniques.md` (Technique 1) | Four components: irony, mental picture, audience/cost, killer title. "Die Hard: A cop comes to L.A. to see his estranged wife and her office building is taken over by terrorists." |
| Beats / "What's the structure?" | `references/1-core-framework.md` (Ch 4, BS2) + `references/3-techniques.md` (Technique 2) | 15 beats from Open Image → Theme Stated → Catalyst → Debate → Break into Two → B Story → Fun and Games → Midpoint → Bad Guys Close In → All Is Lost → Dark Night → Break into Three → Finale → Final Image. |
| Hero / "How do I make him likable?" | `references/1-core-framework.md` (Introduction, Save the Cat!) + `references/3-techniques.md` (Technique 4) | The hero must do something likable by page 10. Sea of Love: Pacino lets father off. Legally Blonde: Elle fights for Bruiser. Lara Croft 2 failed because she was "cool" but unlikable. |
| Genre / "What kind of movie is it?" | `references/1-core-framework.md` (Ch 2, 10 Genres) + `references/4-anti-patterns.md` (Mistake 5) | 10 genres: Monster in the House, Golden Fleece, Out of the Bottle, Dude with a Problem, Rites of Passage, Buddy Love, Whydunit, Fool Triumphant, Institutionalized, Superhero. |
| Outline / "How do I plan my script?" | `references/1-core-framework.md` (Ch 5) + `references/3-techniques.md` (Technique 3) | 40 index cards, 4 rows of 10. One scene per card. "If you can't do it in 40 cards, you don't have a movie." |
| Repair / "Something is wrong — help!" | `references/1-core-framework.md` (Ch 7) + `references/3-techniques.md` (Technique 6, 7) | Six repair tools: Hero Leads, Make Bad Guy Badder, Turn/Turn/Turn, Emotional Color Wheel, Cut "Hi How Are You" scenes, Step Back. "The hero must be active, not reactive." |

### Core Framework Quick Reference

- **Save the Cat!:** Hero must do something likable early. Sea of Love — Pacino lets father off. Opposite: Lara Croft 2. "They spent millions on her latex suit but nothing on making me care."
- **The Logline:** One sentence. Four components: irony, mental picture, audience/cost, killer title. The test: "Why didn't I think of that?"
- **The 15 Beats (BS2):** Open Image (1%) → Theme Stated (5%) → Set-Up (1-10%) → Catalyst (10%) → Debate (10-20%) → Break into Two (20%) → B Story (22%) → Fun and Games (20-55%) → Midpoint (55%) → Bad Guys Close In (55-75%) → All Is Lost (75%) → Dark Night (75-85%) → Break into Three (85%) → Finale (85-99%) → Final Image (99-100%).
- **The 10 Genres:** Monster in the House (Jaws, Alien), Golden Fleece (Star Wars), Out of the Bottle (Liar Liar), Dude with a Problem (Die Hard), Rites of Passage (40-Year-Old Virgin), Buddy Love (When Harry Met Sally), Whydunit (Chinatown), Fool Triumphant (Forrest Gump), Institutionalized (One Flew Over), Superhero (Spider-Man).
- **40 Cards:** 4 rows of 10. Act One = row 1. Act Two = rows 2-3. Act Three = row 4. "Cheap to fix at the card stage."
- **Immutable Laws:** Save the Cat, Pope in the Pool, Double Mumbo Jumbo, Laying Pipe, Too Much Marzipan, Watch Out for That Glacier, Covenant of the Arc.
- **Script Repair:** Six checks — Hero Leads? Bad Guy Baddest? Turns? Emotional Variety? Cut Greetings? Step Back?

### Key Principles

1. **The Audience Must Like Your Hero.** Save the Cat on page 10.
2. **You Must Answer "What Is It?"** One sentence. Before you write.
3. **Structure Is Not Optional.** The 15 beats are a map.
4. **40 Cards, No More.** 4 rows of 10. See the whole movie.
5. **A Great Villain Makes a Great Hero.** Badder = better.
6. **The Promise of the Premise Is Paramount.** Fun and Games = what they paid for.
7. **The Hero Must Change.** Covenant of the Arc. No change = no story.

### Anti-Pattern Summary

The central error: **thinking your script is above structure.** See `references/4-anti-patterns.md`.
