From the source SKILL.md

Prototyping has costs (time, opportunity, sometimes confusion). Picking the right thing to prototype, at the right fidelity, at the right moment, is how teams get the benefits without the costs.

What this skill does

Prototyping When And What is a community-contributed Claude Code skill in the science-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/prototyping-when-and-what/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Prototyping When And What Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 178,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
