Guide users through spec-driven development — from goal clarification through requirements, design, task planning, and incremental execution. Use this skill whenever a user wants to build a new feature with upfront planning, asks for a structured development workflow, mentions "spec-driven", wants to create requirements or a design doc before coding, or invokes /spec-coding. Also trigger when a user has existing spec files (requirements.md, design.md, tasks.md) and wants to continue or execute…

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

A workflow for building features specification-first. Instead of jumping straight
into code, you walk through five stages — each producing a concrete artifact that
the next stage builds on. This front-loaded planning catches design issues early
and produces better implementations.

## Stages

| Stage | Output | Purpose |
|-------|--------|---------|
| 1. Goal Confirmation | Shared understanding | Align on what we're building and why |
| 2. Requirements | `requirements.md` | Define *what* the system does (EARS format) |
| 3. Design | `design.md` | Define *how* it works technically |
| 4. Task Planning | `tasks.md` | Break the design into executable coding steps |
| 5. Execution | Working code | Implement tasks incrementally |

All spec artifacts live in `docs/specs/{feature-name}/` (kebab-case).

## Resuming a Workflow

Users often return to a workflow across multiple sessions. Before starting fresh,
check whether spec files already exist for the feature:

- If `tasks.md` exists with unchecked items → offer to resume at Stage 5 (Execution)
- If `design.md` exists but no `tasks.md` → offer to resume at Stage 4 (Task Planning)

How to install

The exact contents, by fingerprint
mdr add kevinlin/skills/spec-coding@sha256:80880f4bbf599961

The line at the top of this page pins the label v1.0.1, 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.
