spec-driven-development SKILL.md skillA

spec-driven-development from shashankswe2020-ux/whoop-mcp is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add shashankswe2020-ux/whoop-mcp/spec-driven-development@git:20260410.1a22ea0

Pins git:20260410.1a22ea0 in mdr.lock. Pin the fingerprint instead.

Creates specs before coding. Use when starting a new project, feature, or significant change and no specification exists yet. Use when requirements are unclear, ambiguous, or only exist as a vague idea.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Spec-Driven Development

## Overview

Write a structured specification before writing any code. The spec is the shared source of truth between you and the human engineer — it defines what we're building, why, and how we'll know it's done. Code without a spec is guessing.

## When to Use

- Starting a new project or feature
- Requirements are ambiguous or incomplete
- The change touches multiple files or modules
- You're about to make an architectural decision
- The task would take more than 30 minutes to implement

**When NOT to use:** Single-line fixes, typo corrections, or changes where requirements are unambiguous and self-contained.

## The Gated Workflow

Spec-driven development has four phases. Do not advance to the next phase until the current one is validated.

```
SPECIFY ──→ PLAN ──→ TASKS ──→ IMPLEMENT
   │          │        │          │
   ▼          ▼        ▼          ▼
 Human      Human    Human      Human
 reviews    reviews  reviews    reviews
```

### Phase 1: Specify

Start with a high-level vision. Ask the human clarifying questions until requirements are concrete.

How to install

The exact contents, by fingerprint

mdr add shashankswe2020-ux/whoop-mcp/spec-driven-development@sha256:6d098845420d0f7b

The line at the top of this page pins the label git:20260410.1a22ea0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
