A One-Line Memory Instruction Telling Claude to Use ASD-STE100 Simplified Technical English Hits 656K Views as a Fix for Model Verbosity Drift
A post instructing users to save 'always use ASD-STE100 Simplified Technical English when you talk to me' into Claude's memory went viral with 5,871 likes and 656,448 views, framed as the thing that finally stopped Claude's escalating unintelligibility. ASD-STE100 is a controlled natural language developed by the European aerospace industry for maintenance documentation — the January 2025 edition specifies 53 writing rules and roughly 900 approved words — and there is now a packaged Claude Code skill (danyuchn/asd-ste100-skill) applying the same rules to agent-facing English like tool descriptions and inter-agent instructions. The interesting inversion is that a standard built so non-native human readers couldn't misparse a manual is being repurposed so agents can't misparse each other.
