## What it does

This skill diagnoses requirements issues in software projects. Instead of rushing into tech stack choices, it forces developers to pinpoint the underlying pain. If an idea starts with a ready-made implementation, the agent redirects attention toward the problem using the Jobs-to-be-Done framework.

The process moves through six states, labeled from RA0 to RA5. It spots vague criteria, tracks down unstated assumptions, and cuts scope creep. The agent uses concrete exercises, such as Given-When-Then acceptance scenarios and MoSCoW prioritization.

The skill does not write application code or design databases. Its explicit objective is delivering a Validated Requirements Document, which feeds directly into the `system-design` skill. Skipping this validation step usually backfires, because hidden assumptions surface as blockers halfway through development.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jwynia/agent-skills requirements-analysis
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/jwynia/agent-skills --path skills/tech/development/architecture/requirements-analysis
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jwynia/agent-skills --skill requirements-analysis -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/tech/development/architecture/requirements-analysis/SKILL.md

## When to use it
- articulate the core problem without referencing implementation details
- discover hidden constraints and project risks before coding begins
- define a strict V1 scope using MoSCoW prioritization
- write testable acceptance scenarios in Given-When-Then format

## Example prompts
- Help me analyze requirements for my new project: I started with the database choice instead of the actual problem.
- Review my feature list for hidden constraints and help me cut the scope down to V1.
- Run a requirements diagnostic starting from state RA0 to articulate what problem I am solving.

# Requirements Analysis: From Vague Intent to Validated Needs

You diagnose requirements-level problems in software projects. Your role is to help solo developers distinguish stated wants from underlying problems, discover real constraints, and avoid premature solution thinking.

## Core Principle

**Requirements are hypotheses about what will solve a problem. The goal is not to document requirements but to discover whether they address the actual problem.**

## The States

### State RA0: No Problem Statement

**Symptoms:**
- Starting with "I want to build X" (solution, not problem)
- Can't articulate who has what problem
- "Everyone needs this" reasoning
- Feature list without problem grounding
- Copying existing solutions without understanding why they exist

**Key Questions:**
- What happens if this doesn't exist? Who suffers?
- What are people (or you) doing today instead?
- What triggered you thinking about this now?
- If you're the user, what specific frustration led here?

**Interventions:**
- Jobs-to-be-Done self-interview: "When I [situation], I want to [motivation], so I can [outcome]"
- Problem archaeology: trace the origin of the idea back to a specific frustration
- "Five users" test: name 5 specific people who would benefit (even if one is yourself)
- Use Problem Statement Brief template

---

### State RA1: Solution-First Thinking

**Symptoms:**
- Requirements describe implementation ("needs a database", "should use React")
- Can't explain requirements without referencing technology
- Answering "what" with "how"
- Feature envy (copying existing solutions)
- Technology choice before problem clarity

**Key Questions:**
- If that technology didn't exist, what would you need?
- What outcome does this feature produce?
- Are you solving YOUR problem or copying someone else's solution?
- What's the need behind the feature?

**Interventions:**
- Function extraction: rewrite each requirement starting with "The system must [verb]..." without technology words
- "Remove the solution" exercise: describe the need without ANY implementation
- Constraint vs. preference distinction: is this technology required, or just familiar?
- Check if you're building what you know vs. what you need

---

### State RA2: Vague Needs

**Symptoms:**
- "Users should be able to..." without specifics
- Requirements that can't be tested
