## What it does

The skill evaluates requirements and reuses Handoff Context. Before suggesting replacements, it checks the existing repository stack using codebase search tools. It prompts you only for unresolved decisions rather than repeating established choices.

The architectural scope covers the primary user journey: component boundaries, data ownership, integration contracts, deployment target, and failure handling. Paid services, storage, authentication, and external APIs are included only when justified. Credentials and secrets stay out of the generated files.

The output writes to `docs/TechDesign-[AppName]-MVP.md` or a manifest-defined path. It ends with a structured Handoff Context containing constraints, choices, budget, and open questions for the next workflow stage.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add KhazP/vibe-coding-prompt-template --skill vibe-techdesign -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add KhazP/vibe-coding-prompt-template --skill vibe-techdesign -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add KhazP/vibe-coding-prompt-template --skill vibe-techdesign -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install KhazP/vibe-coding-prompt-template vibe-techdesign
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add KhazP/vibe-coding-prompt-template --skill vibe-techdesign -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/KhazP/vibe-coding-prompt-template --path workflow/skills/vibe-techdesign
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add KhazP/vibe-coding-prompt-template --skill vibe-techdesign -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/KhazP/vibe-coding-prompt-template/tree/HEAD/workflow/skills/vibe-techdesign/SKILL.md

## When to use it
- write an MVP technical architecture document for core user journeys
- define service boundaries and integration contracts
- document meaningful technical tradeoffs and recovery constraints
- pass architectural decisions and open questions to the next agent

## Example prompts
- Write an MVP technical design from our agreed requirements
- Create docs/TechDesign-[AppName]-MVP.md in quick mode using the current stack
- Draft the architecture plan and document core integration contracts

# MVP technical design

Read the agreed requirements and reuse Handoff Context. Inspect an existing
project's stack and relevant implementation before proposing replacements.
Ask only for consequential choices that remain unresolved; a known answer
does not need another confirmation echo.

Describe the architecture needed for the core journey: component/service
boundaries, data ownership, integration contracts, deployment target, and
relevant failure behavior. Prefer the smallest design that meets requirements.
Add auth, storage, infrastructure, AI, or paid services only when justified.
Verify changing vendor details from the installed code or official sources.

Record meaningful tradeoffs, compatibility constraints, migration/recovery
requirements where applicable, and how the result will be checked. Distinguish
local test operations from external sends, production writes, and deployments.
Keep secrets out of generated documents. Do not assign broad tool permissions
or require a team of agents to execute an ordinary implementation.

Use the manifest's configured design path or `docs/TechDesign-[AppName]-MVP.md`.
Quick mode can be a short architecture and implementation plan; deeper modes
should expand only where uncertainty or risk warrants it. End with Handoff
Context carrying app, known user level, platform, budget, timeline, mode,
constraints, decisions, source files, and open questions. Continue to the next
authorized workflow stage rather than stopping solely because a document exists.

For a guided interview with unresolved requirements, consult the relevant
[optional question prompts](references/question-bank.md).

When producing a document for `vibeworkflow`, include the exact
[CLI output metadata](references/cli-output.md). This is a parser contract,
not an optional prose template.
