Don't use a five-dollar word when a fifty-centify one will do. An editing pass for technical prose: keep the precise terms that carry information; swap the abstract nouns, math notation, and internal jargon that don't.
Fifty Centify is a community-contributed Claude Code skill in the research-methods sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/fifty-centify/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when editing technical prose for readability: when sentences read like database schemas, when set notation has crept into paragraphs, when phrasing is borrowed from log fields or query plans, when em-dashes or fancy unicode survived avoid-ai-writing, or when the author asked to make a doc "simpler," "less academic," or "easier to read without context.
The Fifty Centify 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 188,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
