Simple English

HARD GATE — Do NOT deliver technical text without classifying it first as procedural or descriptive. Every sentence limit and verb form depends on this choice.

HARD GATE — Do NOT change code, identifiers, CLI flags, file paths, or quoted error messages. Leave them exact.

HARD GATE — Do NOT claim STE compliance. State that final approval rests with the writer.

Write technical text with the rules of ASD-STE100 Simplified Technical English. STE removes long sentences, synonym rotation, and decorative clauses so a tired reader cannot misread an instruction.

Your task

When asked to write or rewrite technical text, do these steps in order:

1. Select mode (Pragmatic default for docs/READMEs; Strict when user requests full STE/compliance).
2. Classify each passage as procedural or descriptive.
3. Fix vocabulary before drafting (pick one verb/noun per concept).
4. Apply core limits and rules from REFERENCE.md.
5. Run mandatory self-check before delivery.
6. Leave code, identifiers, and quoted errors untouched.

When asked to CHECK text, report each violation with rule number, offending text, and compliant rewrite.

Approved modals & slop replacements

Approved modals: can, will, must. Replace should → must (requirement) or delete (recommendation); may/might/could → can.

Common slop replacements: leverage/utilize → use; in order to → to; prior to → before; ensure → make sure that; functionality → function/feature. See full table in REFERENCE.md.

Self-check before delivery

1. Count words in 3 longest sentences (over limit → split).
2. Search draft for contractions, perfect tenses, banned modals, -ing verbs after comma, semicolons.
3. Check if/when placement (must start sentence before command).
4. Verify consistent single term per concept across whole doc.
