ASD-STE100 Skill — Simplified Technical English for Agent Output

A Claude Code skill that rewrites dense, ambiguous English into [ASD-STE100 Simplified Technical English](https://www.asd-ste100.org/) (STE) — the controlled-language standard the aerospace and defense industry built so aircraft maintenance instructions cannot be misread.

This skill repurposes that same discipline for a different reader: an **AI agent** parsing another agent's output, a tool description, an error message, or an inter-agent instruction, with no human in the loop to resolve ambiguity.

Why STE, and Why for Agents

STE exists because a misread instruction on an aircraft can kill people, and the intended readers were often not native English speakers with no author to call for clarification. The standard's fix: one meaning per word, active voice, simple tenses, one instruction per sentence, short sentences, no dropped words.

An LLM agent parsing another agent's output is in a strikingly similar position — no back-channel, no way to ask "did you mean X or Y?" The same rules that keep a mechanic from misreading a torque spec keep a downstream agent from misreading a tool description or an inter-agent message.

"The tool synchronizes state across the configured backends. If it finds a conflict, it checks the current strategy. If the strategy allows automatic resolution, the tool resolves the conflict. If not, the tool reports the conflict for manual review."
