An agent skill that forces ASD-STE100 Simplified Technical English

“Your AI writes like a LinkedIn post. Make it write like a Boeing manual.” SimpleEnglish is a skill that forces LLM documentation into ASD-STE100, the controlled language aerospace has used since 1983 so a tired mechanic cannot misread an instruction: measured 72.9 per cent fewer violations across six Claude models, with AI slop dying as a side effect. The underlying observation (via @geogristle) is that controlled languages built for human safety turn out to be exactly the constraint that stops models writing filler.

In the HN discussion, several people want it for their own emails and Slack messages, one shows an output that is still wordier than real STE, and another notes drily that this is the third ASD-STE100 submission in a fortnight: this week’s trend, though maybe a good one.
