## What it does

This diagnostic skill evaluates story conclusions against six structural failure states. It identifies arbitrary resolutions without prior setup, overly predictable plotlines, deus ex machina interventions, unresolved expanding mysteries, heavy-handed theme explanations, and pacing timing mismatches.

The framework divides the finish into climax, falling action, and denouement. Internal checklists determine whether the final choice answers the main dramatic question and requires the protagonist's actual growth rather than sheer luck.

The logic focuses entirely on fiction. Running this check on technical guides or non-fiction texts will not produce useful results because the criteria depend directly on character arcs.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill endings -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/endings/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/endings/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill endings -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/endings/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill endings -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/endings/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jwynia/agent-skills endings
```

2. **Manually: put the files in place**
- File: `.github/skills/endings/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill endings -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/jwynia/agent-skills --path skills/creative/fiction/structure/endings
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/endings/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill endings -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

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/structure/endings/SKILL.md

## When to use it
- diagnose deus ex machina solutions in a story climax
- fix rushed falling action after high-tension scenes
- spot preachy character dialogue in the resolution
- ensure the protagonist drives the final choice

## Example prompts
- Run the endings diagnostic on my final chapter to see why the climax feels unearned.
- Review the falling action in this draft: does the pacing drop off too quickly after the climax?
- Check my story resolution against state E4 to ensure I am not introducing late mysteries.

# Endings: Diagnostic Skill

You diagnose ending-level problems in fiction. Your role is to identify why resolutions fail and guide writers toward endings that feel both inevitable AND surprising.

## Core Principle

**The best endings feel both inevitable ("of course it had to end this way") AND surprising ("I didn't see that coming").**

This seeming contradiction is resolved by planting seeds throughout the story, having the ending emerge from character and theme, and subverting surface expectations while fulfilling deeper ones.

An ending that's only inevitable feels predictable. An ending that's only surprising feels arbitrary. Both together create satisfaction.

## The Anatomy of an Ending

### Climax
The point of highest tension where the dramatic question is answered.

**Climax must:**
- Answer the central dramatic question
- Force the protagonist's final choice
- Result from story logic, not external intervention
- Require the character to use what they've learned/become

### Falling Action
The decompression after climax. Events settle, consequences manifest, characters process.

**Falling action should:**
- Show immediate aftermath
- Begin revealing implications
- Let reader breathe
- Transition toward resolution

### Denouement/Resolution
The final state—where things end up.

**Resolution should:**
- Provide closure on main plot
- Address major subplots (not necessarily resolve all)
- Show the new normal
- End on a resonant image or moment

## The Ending States

### State E1: Arbitrary Ending

**Symptoms:** Resolution doesn't follow from what preceded it. Ending feels random or disconnected. "Where did that come from?" reaction. Seeds weren't planted.

**Key Questions:**
- Does resolution follow from established character and plot?
- Were the seeds for this ending planted earlier?
- Is this the ending *this specific story* needed?
- Could readers reread and see it coming?

**Diagnostic Checklist:**
- [ ] Ending uses only elements already established
- [ ] Character's choice at climax emerges from arc
- [ ] Resolution matches the story's internal logic
- [ ] On reread, foreshadowing would be visible

**Interventions:**
- Identify what ending the story actually built toward
- Plant seeds earlier for the intended ending
- Ensure climax emerges from character growth, not plot convenience
- Use setup-payoff tool to track what was promised

---

### State E2: Predictable Ending

**Symptoms:** Reader sees ending coming from far away. No surprise at all. Genre conventions followed too literally. Surface expectations met exactly.

**Key Questions:**
- Is there any element of surprise?
- Did you follow genre expectations too closely?
