SimpleEnglish adds stricter technical-English rules for coding agents
SimpleEnglish is an MIT-licensed Agent Skill that asks LLMs to write plain English by default and can apply stricter ASD-STE100 rules on request. Its documentation lists compatibility with Claude Code, Cursor, VS Code Copilot, OpenAI Codex, Gemini CLI, Goose, OpenCode, and other Agent Skills-compatible tools. The project reports that version 2.0.1 reduced visible formatting defects by 95% across 16 Claude replies and lowered STE linter violations by 81.3% across nine Claude models, but no evaluation run is available for version 2.1.0 or later.
The project offers a concrete, reproducible way to impose testable writing constraints on outputs from several widely used coding agents.
Agent skill: make LLMs write docs in ASD-STE100 Simplified Technical
✈️ your AI writes like a LinkedIn post. make it write like a Boeing manual.
An agent skill that makes LLMs write plain English with the discipline of ASD-STE100 Simplified Technical English, the controlled language aerospace has used since 1983 so that a tired mechanic cannot misread an instruction. Layman-readable by default, STE-strict on request.
Works in every agent that reads the Agent Skills standard: Claude Code, Cursor, VS Code Copilot, OpenAI Codex, Gemini CLI, Goose, OpenCode, and about 25 more. One folder, no dependencies, MIT.
