Provide your text and ask for STE rewriting. The skill classifies each passage as procedural or descriptive, applies the 53 ASD-STE100 rules, enforces sentence limits of 20 words for instructions and 25 for descriptions, and runs a self-check before delivering.

ASD-STE100 is a controlled language standard from aerospace maintenance documentation with 53 writing rules and an approved-word dictionary. It removes ambiguity so non-native English readers cannot misread instructions. The official standard is a free download at asd-ste100.org.

Yes, check mode audits your draft and reports each violation with its rule number, the offending text, and a compliant rewrite. A references checklist provides searchable patterns for contractions, banned modals, semicolons, and trailing conditions.

Yes, error messages and runbooks are primary targets. Error messages state what happened, the cause, and the fix as an imperative. Runbooks use one instruction per step with conditions first and warnings before dangerous steps.

Do not apply STE to marketing copy, blog posts, or brand writing because it removes persuasion by design. Use it only for technical facts and instructions where misreading has a cost, such as docs, procedures, and incident reports.

No tool can guarantee full ASD-STE100 compliance because the official approved-word dictionary is copyrighted and not reproduced here. Strict mode applies full vocabulary discipline, but final approval rests with the writer using the official standard.
