# plan-interview

Turns a rough plan into an implementation-ready spec through an adaptive interview. Useful when the idea exists but the requirements don't.

## What it does

The skill runs a structured interview over your plan and writes a spec file next to it. Depth scales with complexity: 10-15 questions for a single clear feature, 18-23 when several components and integrations are involved, 22-28 for cross-system work with many stakeholders. Questions move through phases — scope and success criteria first, then architecture and data, then user flows, risks and operations.

You start it with the slash command `/plan-interview:interview [plan-file]`. It reads your plan file and produces something like `docs/feature-plan-spec.md`. A `spec-reviewer` subagent scores the finished spec across four dimensions — completeness, consistency, clarity and edge cases — 25 points each. Ask it to review your spec and it runs.

The interview skips whatever the plan already answers. Instead it probes edge cases, surfaces assumptions you never wrote down, and flags answers that contradict each other. If the plan is barely a paragraph, expect a long session — that's a sign to fill in scope and goals first, or half the questions will just restate the obvious.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill plan-interview -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill plan-interview -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill plan-interview -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install secondsky/claude-skills plan-interview
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill plan-interview -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/secondsky/claude-skills --path plugins/plan-interview/skills/plan-interview
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill plan-interview -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/secondsky/claude-skills/tree/HEAD/plugins/plan-interview/skills/plan-interview/SKILL.md

## When to use it
- turn a feature sketch into a spec you can code against
- gather requirements through ordered questions instead of a messy list
- surface hidden assumptions and contradictions before implementation starts
- score a finished spec for completeness and edge cases
- pin down risks and rollback plans before the first commit

## Example prompts
- /plan-interview:interview docs/feature-plan.md
- interview me about the plan in docs/payments-plan.md and save the spec next to it
- review my spec for contradictions and missing edge cases

# Plan Interview Skill

Transform rough plans into comprehensive, implementation-ready specifications through adaptive, structured interviews.

## When to Use

- Converting a plan or idea into a detailed specification
- Gathering requirements through structured questioning
- Transforming rough documentation into implementation-ready specs
- Ensuring all edge cases, risks, and stakeholders are considered before implementation

## Available Components

### Command: `/plan-interview:interview [plan-file]`

Adaptive interview that calibrates depth based on plan complexity:

| Complexity | Signals | Questions |
|------------|---------|-----------|
| **Simple** | Single feature, clear scope | 10-15 |
| **Moderate** | Multi-component, some integrations | 18-23 |
| **Complex** | Cross-system, many stakeholders | 22-28 |

**Usage:**
```bash
/plan-interview:interview docs/feature-plan.md
# Output: docs/feature-plan-spec.md
```

### Agent: `spec-reviewer`

Autonomous quality analysis of specifications across 4 dimensions:
- **Completeness** (25 pts) - All sections populated?
- **Consistency** (25 pts) - No contradictions?
- **Clarity** (25 pts) - No ambiguous language?
- **Edge Cases** (25 pts) - Error handling defined?

Triggers when you say "review my spec" or "check specification quality".

## Interview Phases

1. **Foundations & Scope** - Stakeholders, success criteria, constraints, MVP scope
2. **Technical Deep-Dive** - Architecture, data models, scalability, security
3. **User Experience** - Personas, flows, cognitive load, error recovery
4. **Risks & Tradeoffs** - Risk categorization, blast radius, contingency plans
5. **Operationalization** - Testing, deployment, monitoring
6. **Wrap-Up** (optional) - Only for complex plans with remaining gaps

## Interview Philosophy

**Core Principle**: Depth over breadth. Better to deeply understand critical aspects than superficially cover everything.

**Key Techniques**:
- Non-obvious questions - Skip what the plan already answers
- Edge probing - What happens in unusual cases?
- Assumption surfacing - Make implicit beliefs explicit
- Contradiction detection - Flag when answers don't align
- Adaptive depth - Probe deeper on complex areas, move faster on clear ones
