Write or rewrite technical text with the rules of ASD-STE100 Simplified
Technical English so it is clear, unambiguous, and free of AI slop. Use for
documentation, READMEs, runbooks, procedures, error messages, release notes,
incident reports, and API guides. Also use when the user says "STE",
"Simplified Technical English", "ASD-STE100", "de-slop", "make this
readable", "write for non-native readers", or asks for docs that translate
well. Enforces the standard's 53 rules: 20/25-word sentence…
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
# 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).

The line at the top of this page pins the label v1.0.0, 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.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
