Write or audit technical text against ASD-STE100 Simplified Technical English so a tired, non-native reader understands it on the first pass: 20-word procedural and 25-word descriptive sentence limits, imperative steps, condition before command, one word for one meaning, and only the approved modals can/will/must. Use for READMEs, runbooks, procedures, error messages, release notes, incident reports, API guides, UI copy, and agent instructions. Trigger on: "STE…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Simplified Technical English
ASD-STE100 is the controlled language that aerospace and defense manufacturers write maintenance manuals in. It assumes a reader who is tired, under time pressure, and reading English as a second or third language. Under that assumption a sentence that needs a second pass is a defect, so the standard removes every construction that causes one.
The same constructions are what makes generated prose read as generated: rotating synonyms, hedged claims, 40-word sentences carrying three facts, adjectives with no measurement behind them. Fix the text for the tired reader and the machine smell goes with it.
Write so each sentence survives one read.
## Pick the job
**Rewrite** — produce compliant text. Follow the passes below in order.
**Audit** — report violations without changing the text. Give the rule number, the offending span, and a compliant rewrite for each. Read `references/rules.md` before you cite anything: the numbering is not intuitive (Rule 3.1 is about verb forms, not sentence length) and citing from memory produces confident, wrong references.
## Pick the depth

The line at the top of this page pins the label git:20261013.ecfffa1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
