Prototype — Development skill for Claude Code
Validate technical feasibility with minimum code before full implementation.
How to install Prototype
Installs to ~/.claude/skills/ryanthedev-code-foundations-prototype/SKILL.md
mkdir -p ~/.claude/skills/ryanthedev-code-foundations-prototype && curl -fsSL https://raw.githubusercontent.com/ryanthedev/code-foundations/HEAD/commands/prototype.md -o ~/.claude/skills/ryanthedev-code-foundations-prototype/SKILL.md Restart Claude Code, or start a new session, for it to be picked up.
What Prototype does
description: "Validate technical feasibility with minimum code before full implementation"
Skill: prototype
**Prove it works. Minimum code. Maximum learning.**
Master Checklist - Execute In Order
**YOU MUST complete each checkbox before proceeding to the next phase.**
Phase 1: SCOPE
- 1.1 Ask user: "What ONE thing are you trying to prove?"
- 1.2 Narrow until atomic (starts with "Can I...")
- 1.3 State the scope: "SCOPE: [single question]"
P
Alternatives in Development
- Validate Plan — You are tasked with validating that an implementation plan was correctly executed, verifying all success crite 10k ★
- Identify Assumptions Existing — Identify risky assumptions across Value, Usability, Viability, Feasibility 7.8k ★
- /validate — Run full validation on the current finding before writing a report 927 ★
