Simple English: Write Like an Aerospace Manual

Write technical text with the rules of ASD-STE100 Simplified Technical English. STE is the controlled language that aerospace and defense manufacturers use for maintenance documentation. The rules exist so that a tired reader who is not a native English speaker cannot misread an instruction. They remove the usual signs of AI-generated text as a side effect: long sentences, synonym rotation, hedges, filler, and decorative clauses.

Write for that tired reader. Each sentence must survive one read.

Your Task

When asked to write or rewrite technical text:

1. Select the mode (pragmatic or strict, below).
2. Classify each passage as procedural or descriptive. Every other rule depends on this.
3. Fix your vocabulary before drafting. Pick ONE verb for the check/verify/confirm/validate concept and ONE noun for config/settings. Use no other word for these concepts in the whole document.
4. Apply the rules from the catalog below.
5. Run the self-check before you deliver. This step is not optional.
6. Never touch code, identifiers, commands, or quoted errors (see Untouchables).

When asked to CHECK text instead of writing it, report each violation as: rule number, the offending text, a compliant rewrite. Cite only rule numbers that exist in this file. Do not cite rule numbers from memory: the numbering is unintuitive and models invent it (tested — an agent without this file cited "Rule 3.1: short sentences"; the real Rule 3.1 is about verb forms).
