## What it does

The skill walks through four moves: map the agency-control balance, design for non-deterministic model output, define the conversational grammar, and set up short feedback loops. The material comes from Lenny's Podcast and Newsletter, drawn from 14 guests and posts.

Inside you get frameworks rather than code: NLX design elements from Aparna Chennapragada, fault-tolerant interfaces from Gustav Söderström, low-downside patterns for agents, and a note on 200 milliseconds as the latency that keeps a developer in flow. The full list sits in `references/artifacts.md`.

It works by asking questions, so bring a product description and an honest picture of how much control users currently have. Install it once you have an LLM prototype running and need to decide which steps to automate and which to leave manual.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill ai-native-ux -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill ai-native-ux -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill ai-native-ux -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install RefoundAI/lenny-skills ai-native-ux
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill ai-native-ux -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/RefoundAI/lenny-skills --path skills/ai-native-ux
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill ai-native-ux -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/RefoundAI/lenny-skills/tree/HEAD/skills/ai-native-ux/SKILL.md

## When to use it
- decide which steps the model should own and which stay manual
- design a UI that survives a wrong model response
- define the invisible grammar that keeps a chat interface predictable
- add an easy way to correct the AI without breaking the flow
- break a big agent goal into small, testable behaviours

## Example prompts
- help me map the agency-control balance in our onboarding flow
- what NLX elements do we need to make the assistant conversation feel structured
- suggest low-downside patterns for an agent that edits files on its own

# Designing AI-Native User Experiences

Transition from static interfaces to fluid, intent-driven interactions that leverage model intelligence.

Help the user with designing ai-native user experiences using insights from 14 guests and posts across Lenny's Podcast and Newsletter.

## How to Help

1. **Map the Agency-Control Balance** - Assist the user in deciding which tasks the AI should automate versus which requires manual human oversight.
2. **Design for Non-Determinism** - Help create UI patterns that account for varying model outputs and provide easy correction mechanisms.
3. **Structure Conversational Grammars** - Guide the user in defining the invisible rules and structured elements that make natural language interfaces predictable.
4. **Iterate on Feedback Loops** - Help implement simple, high-frequency feedback mechanisms to refine model performance based on user interaction.

## Core Principles

### Design for fluid intent
Aishwarya Naresh Reganti + Kiriti Badam: "Most people tend to ignore the non-determinism. You don't know how the user might behave with your product, and you also don't know how the LLM might respond to that. The second difference is the agency control trade-off."

Move away from fixed buttons and forms toward interfaces where user intentions are expressed through natural language. This requires managing the trade-off between the flexibility of language and the precision of traditional UI.

### Define clear decision boundaries
Adriel Frederick: "And I was like yeah, the reason that falls down is the algorithms don't understand long term effects often, nor do they understand how people might respond to it, nor do they understand your intent for the product, and I think it's really important for product managers to play that role. That is our job. When you are working on algorithmic heavy products, your job is figuring out what the algorithm should be responsible for, what people are responsible for, and the framework for making decisions."

Explicitly establish which decisions belong to the algorithm and which require human intervention. This framework bridges the gap between machine optimization and human intent.

### Build structured grammars for language
Aparna Chennapragada: "Natural language interface. NLX is the new UX. Often I hear a product builders say, 'Oh, yeah. With AI, the model eats the products.' That doesn't mean it's not designed."

Natural language experiences shouldn't be left entirely to the model. Designers must define the invisible UI constructs and grammars inherent in specific contexts like meetings or podcasts.

### Implement effortless correction
