Plain Language Rewrite Skill

Plain language has a bad reputation because it's done badly — "simplifying" that quietly drops the qualifiers, rounds the numbers, and turns precise claims into vibes. Done right, it's a translation with a fidelity guarantee: every fact, number, condition, and hedge in the original survives; what changes is the packaging — sentence length, word choice, structure, and the jargon triage (most terms translate; some are load-bearing and get kept-and-defined instead, because renaming a term of art creates confusion downstream). The test is a reader who knows nothing and a checker who knows everything, both satisfied.

What This Skill Produces

• The rewrite — the same content at the target reading level, structured for the new reader
• The fidelity check — facts/numbers/qualifiers in original vs. rewrite, diffed to zero loss
• The jargon ledger — each term: translated (to what) / kept-and-defined (why it's load-bearing)
• The audience calibration — what the target reader knows, and the one-notch rule applied

Required Inputs

Ask for these if not provided:

• The text — verbatim; translation works on actual sentences
• The audience, concretely — "customers who don't know insurance" beats "general public"; the rewrite calibrates to what they already know, and one text can't serve experts and novices simultaneously (say so when asked to)
• The load-bearing terms — which jargon is contractual, regulatory, or searchable-by-the-reader (those get kept-and-defined; renaming "deductible" to "your share" helps nobody who then reads their policy)
• The stakes — legal/medical/financial texts keep their hedges verbatim-in-meaning; marketing texts have more freedom — the fidelity bar scales up with stakes

Framework: The Translation Rules

1. Fidelity is the contract: before rewriting, extract the original's claims list (facts, numbers, conditions, hedges); after, diff the rewrite against it. "Usually," "up to," and "unless" are content, not decoration — a plain rewrite that drops them is a different document with better fonts.
2. The jargon triage, not the jargon purge: each term gets a verdict — translate (internal shorthand, latinate padding: "utilize"→"use", "prior to"→"before") or keep-and-define (terms of art the reader will meet again: "your deductible — the amount you pay before insurance starts paying"). The ledger records both, because reviewers will ask.
3. Sentence surgery before word surgery: the biggest readability gains are structural — one idea per sentence, front-loaded subjects, lists for parallel items, 20-ish words average. Swapping words inside 60-word sentences polishes the unreadable.
4. Calibrate one notch below the audience's floor: write to slightly simpler than the audience needs — comprehension costs nothing extra for strong readers, and the weakest reader in the audience is the one the text exists to reach. But never condescend in tone: plain is respectful; simplified-with-a-pat-on-the-head is not.
5. The two-reader test: a target-audience reader retells the content correctly (comprehension) AND a subject-matter expert confirms nothing became false (fidelity). Passing one test is easy; the skill is passing both, and the output states both results.

The Two-Reader Result

[Comprehension: retellable? · Fidelity: expert-clean? · the stakes note for legal/medical texts: hedges preserved verbatim-in-meaning]

Quality Checks

• [ ] The claims list was extracted before rewriting and diffed after
• [ ] Every qualifier survives — no "usually" became "always"
• [ ] Load-bearing terms were kept-and-defined, not renamed
• [ ] Sentence structure did the heavy lifting before word swaps
• [ ] Both readers pass: the novice retells it; the expert signs it

Anti-Patterns

• [ ] Do not simplify by deletion — dropped hedges are the classic plain-language malpractice
• [ ] Do not rename terms of art — the reader meets "deductible" again five minutes later
• [ ] Do not write down at the audience — plain and respectful are the same register
• [ ] Do not serve two audiences with one text — name the split when asked to
• [ ] Do not skip the expert pass on high-stakes text — readable-but-wrong is the worst outcome on the board
