## What it does

This is a diagnostic skill, not a prose generator. You describe what's wrong with your branches, and it sorts the situation into states: meaningless choices, unmanageable branching, a false choice the player has spotted, agency versus authored meaning, story that reads like a flowchart, multiple endings that land flat. Each state comes with questions to answer and interventions to try.

It also carries a table of interactive fiction types — parser-based, choice-based, hybrid forms like visual novels and RPGs, tabletop scenarios — with the strengths and weaknesses of each. The branching math gets its own section: three binary choices make eight paths, five make thirty-two, ten make one thousand twenty-four. That's where foldback, delayed consequences and bottleneck structures come in.

The stance is blunt: agency and authorship coexist, and a false choice breaks player trust. If your store page promises agency while every branch reconverges in the next scene, that's worth checking before release. The skill won't write your branches for you — it asks questions and suggests specific fixes.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill interactive-fiction -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/application/interactive-fiction/SKILL.md

## When to use it
- work out why choices in the game feel hollow
- cut the number of true branches without losing variation
- tell an acceptable false choice from one that breaks trust
- fit player freedom inside a climax you already wrote
- stop scenes from reading like a flowchart

## Example prompts
- Diagnose my branching visual novel: three choices in chapter one, all leading to the same scene. What's wrong?
- I have 10 binary forks and I'm drowning in text. How should I restructure?
- Players say the endings don't feel earned. Check my ending structure.

# Interactive Fiction: Diagnostic Skill

You diagnose problems in branching narratives and player-driven stories. Your role is to help writers balance meaningful player agency with coherent narrative.

## Core Principle

**Agency and authorship coexist.**

The tension between player freedom and narrative coherence is a false dilemma. The best interactive fiction provides meaningful choices, authored emotional payoff, and constrained agency within a designed possibility space.

## Interactive Fiction Types

| Type | Interaction | Strengths | Weaknesses |
|------|-------------|-----------|------------|
| **Parser-based** | Natural language commands | High freedom, puzzle-oriented | "Guess the verb" friction |
| **Choice-based** | Select from options | Constrained, easier to author | Risk of false choices |
| **Hybrid (VN, RPG)** | Multiple modes | Rich, persistent state | High authoring burden |
| **Tabletop scenario** | GM interprets | Dynamic, improvisational | Requires facilitator |

## The Interactive Fiction States

### State IF1: Meaningless Choices

**Symptoms:** Choices don't matter. All paths converge immediately. Players stop caring about decisions. "It doesn't matter what I pick" feeling.

**The Meaningful Choice Test:**
1. **Distinct options** — Each choice represents different approach/value
2. **Perceivable consequences** — Player sees results (even if delayed)
3. **Irreversibility** — Can't immediately undo and try another
4. **Character expression** — Choice reveals something about protagonist

**Key Questions:**
- Does each choice lead to different content?
- Can players perceive consequences within this session?
- Are choices about values/approaches or just navigation?
- Do choices express character or just optimize outcomes?

**Interventions:**
- Add delayed consequences (choice sets flag, affects later scene)
- Make choices about values, not right/wrong
- Show consequences visibly (even small ones)
- Use foldback structure that varies texture, not just destination
