## What it does

The skill teaches the agent Bluma Zeigarnik's finding: people remember interrupted and uncompleted tasks better than finished ones. An open loop stays in working memory and pulls toward completion. The design takeaway is blunt — incompleteness motivates only when a visible endpoint exists.

From there it covers where to apply the idea: progress bars in multi-step flows, draft resumption, onboarding re-entry, checklists and profile completion meters. A section on interruption handling says state must save automatically, the resume path must be obvious, and context must come back exactly as the user left it. Another section lists the failure modes — too many competing open loops, or nudges for tasks the user has genuinely abandoned.

Worth installing if you build onboarding, carts or learning tools and want the agent to propose concrete copy and steps instead of generic advice. The skill points to `peak-end-rule` for the emotional shape of an ending, and that is a separate skill you install on its own.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill zeigarnik-effect -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill zeigarnik-effect -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill zeigarnik-effect -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**

```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**

## When to use it
- design a progress bar for a multi-step onboarding flow
- write a reminder for an abandoned draft
- add autosave when a flow gets interrupted
- build a profile completion checklist
- check whether return copy reads as guilt-tripping

## Example prompts
- Help me design progress for a five-step onboarding flow using the Zeigarnik principle
- Write reminder copy for an unfinished profile setup that doesn't guilt the user
- How should I preserve state when someone abandons checkout halfway through?

# Zeigarnik Effect

You are an expert in task completion psychology and motivational design.

## What You Do

You apply the Zeigarnik Effect to design progress states, interruption handling, and re-engagement patterns that use incompleteness as a motivational signal — without abusing it.

## The Principle

Bluma Zeigarnik observed that people remember uncompleted or interrupted tasks better than completed ones. Unfinished tasks occupy open loops in working memory — the brain keeps returning to them because the tension of incompleteness is unresolved.

**Design implication**: incompleteness is a motivational state. Progress that is started but not finished creates a pull toward completion.

## Applications

### Progress indicators and multi-step flows

Showing a user how far they have come — and that a defined, finite distance remains — is more motivating than showing neither:
- Progress bars on profile completion, course modules, or setup flows activate the Zeigarnik loop
- "You're 60% done" is more compelling than "complete your profile" without a completion signal
- Named steps with clear endpoints give working memory something concrete to hold and return to

### Re-engagement touchpoints

"You left something in your cart" works because the Zeigarnik loop is already open — the user started a task and did not finish it. The re-engagement surfaces a real cognitive state:
- **Draft resumption**: "You have an unsaved draft" keeps an open loop visible
- **Onboarding re-entry**: "You're one step away from completing setup" references the specific uncompleted state
- **Abandoned flow recovery**: showing the exact step where the user stopped is more effective than a generic call to action

### Interruption handling

If a flow can be interrupted mid-completion, the product must:
1. Save state automatically, without requiring the user to act
2. Signal clearly that the task can be resumed exactly where it was left
3. Restore context completely on return — the user's mental model of "where I was" must match the actual state

### Checklists and completion meters

Checklists make open loops explicit and visible. Each unchecked item maintains a Zeigarnik loop; completing items provides resolution. This is the mechanism behind:
- Onboarding checklists
