SimpleEnglish

SimpleEnglish is an agent skill that makes LLMs write plain English following ASD-STE100 Simplified Technical English, the controlled language aerospace has used since 1983. Plain mode (default) is layman-readable: answer first, no em-dashes or bold, terms defined inline. Strict mode adds STE dictionary discipline when STE or ASD-STE100 is named. Measured: about 95% fewer visible reply defects and 78% fewer linter violations in documents. One dependency-free folder under MIT, works in Claude Code, Cursor, Codex, Gemini CLI and roughly 30 agents supporting the Agent Skills standard.
