## What it does

The skill walks a person through nine steps: context, first principles, timing, stakeholders, biases, opportunity cost, scenarios, open questions and synthesis. What comes out is a tool the decision-maker uses, not a verdict handed to them. That matters when the factors are many and they pull in different directions.

Four output formats. The main one is an interactive HTML wizard with a progress indicator, one question per screen and state kept across steps. There is also a markdown framework for plain-text work, a voice summary of 5–7 paragraphs and a PDF report for sharing. The frameworks ship with it: a first-principles test, a ten-item bias checklist (FOMO, sunk cost, confirmation and the rest), an opportunity cost calculator, a scenario matrix, a pre-mortem, plus 10-10-10 and regret minimisation.

Accessibility is treated as a first-class requirement: semantic HTML with ARIA labels, keyboard navigation, WCAG AA contrast, a reduced-motion option, graceful degradation without JavaScript and touch targets of at least 44px. Different thinking styles get different views — matrices and weighted scores for analytical people, gut-check prompts for intuitive ones, diagrams for visual ones. Skip it for trivial calls or emergencies; nine steps will only slow you down there.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add glebis/claude-skills --skill decision-toolkit -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add glebis/claude-skills --skill decision-toolkit -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add glebis/claude-skills --skill decision-toolkit -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install glebis/claude-skills decision-toolkit
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add glebis/claude-skills --skill decision-toolkit -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/glebis/claude-skills --path decision-toolkit
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add glebis/claude-skills --skill decision-toolkit -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/glebis/claude-skills/tree/HEAD/decision-toolkit/SKILL.md

## When to use it
- break a big decision into nine checkable steps
- catch FOMO and sunk cost before signing a partnership
- work out what else those hours could produce
- map outcomes by probability and expected value
- produce a PDF rationale to share with a team

## Example prompts
- Build an interactive wizard for my partnership decision: context, options, stakeholders
- Run my tool-selection choice through the bias checklist and scenario matrix
- Write a 6-paragraph voice summary of the hiring decision

# Decision Toolkit

## Overview

Create structured decision support materials that help humans think through significant choices systematically. This skill produces interactive tools, not just analysis — empowering the decision-maker rather than deciding for them.

## Philosophy

### Principles

1. **Guide, don't decide** — Tools illuminate the decision space; humans choose
2. **One thing at a time** — Reduce cognitive load through progressive disclosure
3. **Multiple lenses** — Same decision viewed through different frameworks reveals blind spots
4. **Biases visible** — Make cognitive biases explicit and checkable
5. **Actionable output** — End with concrete next steps, not abstract conclusions

### Accessibility First

- Support screen readers (semantic HTML, ARIA labels)
- Keyboard navigable (tab order, focus states)
- High contrast by default (WCAG AA minimum)
- Reduced motion option
- Works without JavaScript (graceful degradation)
- Mobile-friendly touch targets (44px minimum)

### Cognitive Inclusivity

Different people process decisions differently:

| Style | Accommodation |
|-------|---------------|
| **Analytical** | Numbers, matrices, weighted scores |
| **Intuitive** | Gut-check prompts, "how does this feel?" |
| **Visual** | Diagrams, progress bars, color coding |
| **Verbal** | Written summaries, question prompts |
| **Sequential** | Step-by-step wizard flow |
| **Global** | Dashboard overview option |

## When to Use

Invoke this skill when user faces:
- Collaboration/partnership decisions
- Career or job changes
- Investment of significant time/money
- Project prioritization
- Technology/tool selection
- Any choice with multiple factors and uncertainty

**Not for**: Trivial decisions, emergency responses, or when user just needs information.

## Decision Types

### Type 1: Opportunity Evaluation
*Should I pursue this opportunity?*
- Partnership, job offer, investment, project

### Type 2: Resource Allocation
*Where should I invest my time/money/attention?*
- Prioritization, budgeting, focus areas

### Type 3: Risk Assessment
*What could go wrong and is it worth it?*
- New ventures, changes, experiments
