## What it does

The skill brings Cialdini's persuasion framework directly into your agent workflows. It covers 7 core principles: reciprocity, commitment and consistency, social proof, authority, liking, scarcity, and unity. The agent reviews landing pages, pricing models, and sign-up funnels to highlight persuasive leverage without deceptive practices.

Assessments run against a target score of 10/10. Top scores of 9-10 require truthful claims, full reversibility, and deliberate layering. Introducing dark patterns, fake scarcity, or hidden costs immediately caps the score at <=3 regardless of how well other elements perform.

The framework references internal guides such as `references/reciprocity.md` and `references/social-proof.md`. For price bargaining or viral growth loops, this skill directs users to companion tools `negotiation` and `contagious`.

## Requirements
- Works with: Unity

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill influence-psychology -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill influence-psychology -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill influence-psychology -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install wondelai/skills influence-psychology
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill influence-psychology -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/wondelai/skills --path influence-psychology
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill influence-psychology -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/wondelai/skills/tree/HEAD/influence-psychology/SKILL.md

## When to use it
- audit copy and landing pages for dark patterns
- restructure onboarding with foot-in-the-door commitment steps
- integrate honest social proof markers into sign-up flows
- increase conversion rates by applying ethical reciprocity triggers

## Example prompts
- Review this checkout page copy and tell me how to reach a 10/10 persuasion score
- Help me structure our free trial sequence using ethical reciprocity
- Rewrite this feature onboarding step using commitment and consistency

# Influence Psychology Framework

Apply six decades of persuasion science — Cialdini's research into why people say "yes" — to product, copy, and sales, ethically.

## Core Principle

**People don't make decisions rationally — they use mental shortcuts (heuristics) that can be triggered to influence behavior.** These shortcuts evolved because they're usually reliable, but they can also be exploited. Understanding them lets you design products, messaging, and experiences that align with how people actually decide.

## Scoring

**Goal: 10/10.** When reviewing or creating persuasive elements (features, copy, flows, campaigns), run the Quick Diagnostic, then score against the bands below and apply the ethics gate. Always report the current score and the specific change needed to reach 10/10.

- **9-10** — Multiple principles deliberately layered; every claim truthful; users can reverse the decision; passes the transparency test (still works if the user knows the strategy); safe for vulnerable users.
- **7-8** — Principles deliberately layered and honest, but one gap (e.g. weak reversibility, or a single principle where layering was possible).
- **5-6** — One principle present but generic, or leverage left on the table.
- **<=3** — No principle deliberately designed (relying on luck), OR any tactic is deceptive/coercive. Any fabricated proof, fake scarcity, or hidden-cost dark pattern caps the score at 3 regardless of other strengths.

## The Seven Principles of Influence

### 1. Reciprocity

**Core concept:** People feel obligated to give back to those who have given to them first.

**Why it works:** Humans are wired to avoid being indebted — the obligation to repay can overpower personal preference, and the return favor often exceeds the original gift.

**Key insights:**
- The gift must come first (before the request)
- Unexpected, personalized gifts beat expected, generic ones
- Even small gifts create obligation

**Product applications:**
