Clear, Natural English Editing

Improve the reader's understanding, not a detector score. A good reference can have repeated terminology, regular tables, definitions and no anecdote. Keep the user's intended voice and the destination's format.

Facts Are Not Style Material

• Preserve supplied numbers, units, dates, versions, names, citations, negation, uncertainty and claim scope. Do not silently update a historical date.
• Never invent a count, quote, interview, personal experience, experiment, failure, comparison or source to make prose more vivid.
• Add specificity only when the supporting evidence supplies it. If no measurement exists, retain uncertainty or remove an unsupported claim. An unsupplied number is not an improvement over a vague quantity.
• Label illustrative scenarios as hypothetical. Do not present them as a real case study or treat their invented values as proof of a product claim.
• Preserve identifiers, executable code and technical obligations. Words such as may, must, can and will are not interchangeable style alternatives.
• Reuse provided facts without asking the user to repeat them. Research a material factual gap when research is in scope; otherwise identify the gap without manufacturing an answer or blocking supported edits.

Match the Genre

Contractions, fragments, humour, analogies and direct address are options, not quotas. Use them when they fit the audience and improve comprehension. Parallel lists and consistent terminology can be desirable in documentation.

Editing Procedure

1. Identify the reader's task, genre, source material and protected facts from the existing request and draft. Do not add an unnecessary intake questionnaire.
2. Remove empty intensifiers and duplicated ideas. Use direct verbs when meaning is preserved; keep connectors that express real causality or contrast.
3. Clarify who acts, on what, under which conditions and with what result. Do not supply a result that the source does not establish.
4. Fix awkward rhythm where it hinders reading. Do not maximize variation, enforce a paragraph pattern or replace terms to appear less predictable.
5. Compare input and output for semantic changes. Check quantities with their units, denominator, time frame and uncertainty, not just the numeral.
6. Return the edited text and any necessary factual caveat. Once the edit is sufficient, continue the remaining requested publication workflow rather than starting another stylistic pass automatically.

Examples: Same Facts, Clearer Prose

These are editing fixtures, not results from a deployed product. Unknown sample size stays unknown; a date, denominator and version do not disappear for fluency.

Verification

• Every changed factual assertion still maps to the supplied material or a source actually checked for this task.
• Conditions, uncertainty, negatives, numbers, units, dates, versions and code are preserved unless an evidence-backed factual correction was requested.
• The result helps its intended reader without an unrequested genre change.
• No invented testimony or detector-evasion claim was added.

A no-change verdict is valid for an already clear passage. Do not add numbers, questions, opinions, deliberate errors or fake admissions to satisfy a score.

Gotchas

• Detector score as evidence: it establishes neither authorship nor factual accuracy. Do not promise an undetectable edit.
• Replacing every vague quantity: guessing a plausible percentage fabricates evidence when the sample size is unknown.
• Forced informality: slang can make a reference harder to understand, particularly for readers using English as an additional language.
• Synonym churn: repeating a technical term is safer than creating a false distinction through alternate names.
• Example contamination: a skill example is not an event that happened to the user or author.

Troubleshooting

Sources and Maintenance

Reviewed 2026-09-06. Owner: the existing writing-skill maintainers. Change through canonical Git, focused before/after fixtures, independent review and the supported installer; retain the prior revision and installation backup for rollback. Refresh sources when guidance changes or a factual/genre regression is observed, not by automatically rewriting working prose on a schedule.

• Developer documentation voice and tone, updated 2026-05-27: clarity and audience matter more than forced informality.
• GPT detectors are biased against non-native English writers, revised 2023-07-10: limitations of the evaluated detectors, not a test of every current detector or a guarantee about any individual passage.
• Excess vocabulary in biomedical publications, revised 2025-07-03: corpus-level biomedical analysis, not an individual-author test or a prescriptive word blacklist.
