Lesson 4.1: Prompts for writing and editing at work

Learn prompts for drafting, editing and reshaping work writing, from the four levels of edit to cutting a long text, while keeping your facts and voice.

By the end of this lesson you will be able to choose the right kind of help for a writing job, from a first draft to a light proofread, write prompts that change only what you want changed, shorten and reshape text for a new reader, keep your own voice and your own facts intact, and avoid the stock phrases that mark text as machine-written. You will use a four-level model of editing, work out how much a long text must be cut to reach a target, and estimate the time a drafting habit can save across a week. You should have read Module 3, especially Lessons 2.3 and 3.4, since good writing prompts combine format and tone control with a critique and revision loop. No technical background is needed.

Writing is the use of assistants that nearly everyone tries first, and it is where the gap between a thin prompt and a careful one shows most. A prompt like "write an email about the delay" returns something that could belong to anyone. A prompt that supplies the facts, the reader, the voice and the limits returns something you can send. This lesson shows how to get the second kind, and how to edit what you already have.

Three kinds of writing job

Most work writing falls into one of three jobs, and each needs a different kind of prompt. Job · You bring · The assistant does · The main riskDraft · Facts, purpose, reader · Produces a first version from your material · Invented details, a generic voice Edit · A draft of your own · Improves it while keeping your meaning · Changes to facts or voice you did not want Reshape · Finished text · Converts it: shorter, simpler, for a new reader, as bullets · Lost nuance, altered numbers Knowing which job you are doing decides what to say. For a draft, the most important thing is to supply the facts and say they are the only ones. For an edit, it is to say what to change and what to leave alone. For a reshape, it is to say who the new reader is and what must survive.

Drafting from your material

A draft is easier to improve than a blank page, and an assistant can produce one in seconds. The quality depends almost entirely on what you supply. A good drafting prompt has five parts: the purpose, the reader, the facts, the shape and the voice.

text Draft an email from me (Meena, project manager) to Mr Rao, finance head at a client bank.

Purpose: ask him to approve the revised integration plan by Friday 6 November.

Facts you may use (only these): - The go-live moves from 14 November to 28 November. - The reason is that the client's security review took longer than planned. - All other milestones are unchanged. - The revised plan is attached as "Plan v2".

Shape: subject line under 8 words; three short paragraphs; one clear request. Voice: polite, direct, no blame. No exclamation marks. Under 120 words. Do not add any fact that is not listed above.

The final line is the guard against invention. Without it, an assistant often adds a plausible reason or an apology for a problem you did not mention.

A useful variation is to ask for an outline first, especially for longer pieces. "Propose an outline with a one-line summary of each section. Do not write the text yet." You approve or change the outline, and then ask for the draft against it. Fixing structure at the outline stage is far cheaper than rewriting a finished document, which is the plan-then-execute pattern of Lesson 3.2.

Giving it your voice

An assistant's default voice is smooth and a little generic. To get yours, paste two or three short samples of your own writing and say: "Match the tone, sentence length and level of formality of these samples. Do not copy their wording." A few of your own lines teach more than a paragraph of adjectives. If you write for an organisation, add its style sheet from Lesson 3.3.

The stock phrases to ban

Machine-written text has recognisable habits: openings such as "I hope this email finds you well", pairs of adjectives, grand claims such as "in today's fast-paced world", and endings that summarise what the reader just read. Readers notice, and it weakens trust. Add a line to your standing instructions or prompt: "Avoid clichés and stock openings. Do not start with a greeting about how the reader is. Do not end by repeating the message." Then read the draft aloud and cut any sentence you would never say.

Editing your own writing

Editing is a spectrum, and asking for "edit this" without saying which level you want is the commonest cause of a disappointing result. Four levels cover the range. Level · What it changes · Typical share of words changed · Use it whenProofread · Spelling, punctuation, obvious typos · 1 to 3% · The text is ready and you want a final check Copyedit · Grammar, consistency, word choice, style-sheet rules · 3 to 8% · The content is settled and you want it clean Line edit · Sentence-level clarity, rhythm, tightening · 10 to 25% · The ideas are right and the prose is clumsy Developmental edit · Structure, argument, what is missing or excessive · 25% or more, and reordering · The draft does not yet work Predict first: you paste a finished report and type "Make this better." Which level of edit do you think you will get, and what might go wrong? Decide before reading on.

Often you will get something between a line edit and a developmental edit, with sentences reworded, sections reordered and favourite phrases swapped, when you wanted only a light clean-up. Facts and figures may shift in the process. Say the level, and the boundary.

Prompts for each level

text Proofread the text below. Fix only spelling, punctuation and obvious typos. Change nothing else: not wording, not order, not numbers. Return the corrected text, then a list of every change you made.

text Copyedit the text below to our style sheet [PASTE]. Fix grammar and consistency only. Keep every sentence's meaning and every figure exactly as written. Return the edited text, then a table of changes with columns Original, Edited and Reason.

text Line edit the text below for clarity and brevity, aiming for about 20 per cent shorter. Keep my meaning, my facts and my voice. Do not add new points. Flag, but do not fix, any sentence whose meaning is unclear to you.

text Give me a developmental review of the draft below. Do not rewrite it. Tell me: what the main point is, whether the order serves it, what is missing for a reader who is a branch manager, and what could be cut. Then list the three most important changes in priority order.

Two features recur. Each prompt says what to change and what to leave alone, and each asks for a list of changes. The list is a form of track changes: you can review what was altered, accept the good edits and reject the rest, and it makes silent changes to numbers much easier to spot.

Editing when facts matter

Whenever you edit text containing figures, names, dates or quotations, assume the assistant could alter one. After the edit, compare them against your original. A quick method is to ask: "List every number, date and name in the original, and confirm each appears unchanged in the edited version." Then check the list yourself. This is the verification habit of Lesson 2.4 applied to editing, and it takes a minute.

Reshaping: cutting, simplifying and changing the reader

Reshaping converts finished text for a new purpose. The most common reshaping task is cutting.

Cutting to a target

Telling an assistant to "make it shorter" gives an arbitrary result. A target gives a measurable one. Work out how much has to go. Suppose a report summary runs to 800 words and the slot allows 250. You must cut 550 words, which is 69 per cent of the text. At an average of about 18 words a sentence, that is roughly 30 sentences. A cut that deep cannot be done by trimming adjectives. It means choosing what matters, and a good prompt says what to keep.

A better cutting prompt names what is non-negotiable: "Cut this to 250 words. Keep the decision, the three figures and the deadline. Cut background, examples and repetition. Keep my original wording where you can." For the deepest cuts, do it in two steps: first ask for the key points in a list, then ask for the text built from those points.

Other reshaping jobs

For a new reader. "Rewrite this technical note for a branch manager with no data background. Explain any term that cannot be avoided in one clause, and keep the figures." Simplify. "Rewrite at a reading level suitable for a general reader, aiming for sentences under 15 words." Lesson 2.3's reading-ease measure can check the result. Convert format. "Turn these meeting notes into a decision log with the columns Decision, Owner and Date. Use 'not stated' for anything missing." Combine. "Merge these three updates into one summary of at most 150 words. Where they disagree, show the disagreement." Translate. "Translate the message below into Hindi in a polite, professional register, and keep the amounts and dates unchanged." Have a fluent reader review any translation that will be sent, since tone and politeness conventions differ between languages.

Matching the prompt to the document

Different workplace documents fail in different ways, and a prompt can guard against the typical failure of each. Document · Typical failure · What to add to the promptEmail · The request is buried, or the tone is off · "State the request in the first two sentences. One ask only." Status report · Too long, no clear message · "Start with one line: green, amber or red, and why." Proposal · Features listed, benefits missing · "For each feature, say what it means for the reader in one clause." Policy or procedure · Ambiguous, passive and hard to follow · "Use numbered steps. Name who does each step. Use 'must' for rules." Announcement · Vague, no date or action · "Include what is changing, from when, who is affected and what to do." Social or marketing text · Generic claims and exaggeration · "No superlatives. Every claim must come from the facts I gave." A habit that serves all of them is to ask, at the end of the prompt, for one sentence stating the main message. "After the draft, write the single sentence you think the reader should remember." If that sentence is not the one you intended, the draft has a problem, and you have found it before the reader does.

Originality, confidentiality and honesty

Three cautions apply to every writing task.

Originality. An assistant produces text from patterns in what it was trained on, and while it does not usually copy passages, it can reproduce familiar phrasing, and in rare cases close to existing text. For anything published under your name or your organisation's, run the checks you would run on any draft, and do not present generated text as a quotation or as someone else's work. If you ask for an example in the style of a named writer, treat the result as an exercise and not as something to publish.

Confidentiality. Drafts often contain details that should not leave your organisation: client names, unreleased figures, personal data. Before you paste a draft into a tool, ask whether it is an approved one and whether the content is allowed. Where it is not, replace the sensitive details with placeholders and restore them afterwards, a habit described in Lesson 2.2. Lesson 6.3 returns to this in full.

Honesty. Do not use an assistant to produce testimonials, reviews or statements of fact that you cannot support. A persuasive paragraph about a benefit that does not exist is a liability, however well written. Many organisations now have rules about when AI use must be disclosed in documents, particularly for regulators and clients. Find out the rule where you work and follow it.

A writing workflow that holds up

For anything important, a short sequence beats a single clever prompt.

1. Gather your facts in a list before you open the assistant. This is your source of truth. 2. Ask for an outline and adjust it. 3. Draft against the outline, with the facts fenced and the "only these facts" rule. 4. Critique against a rubric, as in Lesson 3.4, and revise only the flagged points. 5. Edit at the right level, with a list of changes. 6. Verify the facts against your list, and read it aloud for voice. 7. Own it. Whatever the tool did, you sign the text, and you are responsible for what it says.

The last step carries weight. Where your organisation has rules about disclosing the use of AI in documents, follow them, and never present generated text as someone else's work. Check the policy for client-facing or regulated documents.

What a writing habit is worth

The gain is easy to estimate. Suppose you write ten documents a week, each taking 25 minutes by hand. With a good drafting and editing routine, including the time to supply facts and verify, each takes 10 minutes. The saving is 15 minutes a document, or 150 minutes, two and a half hours, a week. Over 46 working weeks that is about 115 hours. The saving shrinks quickly if you skip the verification, because then you are not saving time, you are borrowing it from whoever finds the mistakes.

Worked examples

Example 1: a hard email. A team lead must tell a vendor that a contract will not be renewed. She supplies the facts (the end date, the reason in one neutral sentence, the handover steps), asks for a firm, courteous tone with no blame and no promise of future work, and asks for two versions of different lengths. She picks the shorter, changes one sentence to match how she speaks and sends it, after checking that the date matches the contract. Total time: eight minutes.

Example 2: a line edit with a safety list. An analyst's two-page memo is accurate but dense. She asks for a line edit "about 20 per cent shorter, same facts and voice" and a list of changes. The result is 18 per cent shorter. Scanning the list, she notices that "Q3" was changed to "the third quarter" in one place and "the quarter" in another, which would have confused the reader, and that a figure of 14.2 per cent had been written as 14 per cent. She restores both and keeps the rest.

Example 3: from notes to a decision log. After a long meeting, a project manager pastes her rough notes and asks for a table of decisions with owner and date, writing "not stated" for anything missing. The model produces six rows, two of them with "owner: not stated". Those two gaps are exactly the items she needs to chase, and she would not have noticed them in her notes. Reshaping into a table made the missing information visible.

Common mistakes

Asking to "make it better". Say which level of edit you want and what to leave alone. No limit on facts. Without "only these facts", drafts gain invented details. Editing text with numbers and not checking them. Compare every figure, date and name after the edit. Accepting generic voice. Paste samples and ban stock phrases. Cutting without saying what to keep. A deep cut needs priorities. Skipping the list of changes. Without it you cannot review what was altered. Translating without a fluent reviewer. Tone and politeness can shift between languages. Forgetting who is responsible. You are accountable for the final text, and for following any disclosure rules.

Key takeaways

Writing help falls into drafting, editing and reshaping. Each needs different instructions: facts for drafting, boundaries for editing and the new reader for reshaping. A draft prompt supplies purpose, reader, facts, shape and voice, and says to use only the listed facts. An outline first fixes structure cheaply. Editing has four levels, proofread, copyedit, line edit and developmental, changing roughly 2, 5, 17 and 35 per cent of the words. Name the level and ask for a list of changes. To cut text, work out the share to remove and say what must survive. A cut above about 40 per cent is a choice about priorities. Check facts after every edit, paste voice samples, ban stock phrases and keep human review for anything sent to others. A good routine can save hours a week, but only if the checking time is counted in.

Check yourself

1. What is the difference between a copyedit and a line edit? A copyedit fixes grammar, consistency and style-sheet points. A line edit rewrites sentences for clarity and rhythm, changing more of the text. 2. Why ask for a list of changes? It lets you review and reject edits, and it exposes silent changes to facts or numbers. 3. A 1,200-word text must become 300 words. What share must be cut? 900 ÷ 1,200 = 75 per cent. 4. What line prevents invented details in a draft? "Use only the facts listed above. Do not add any fact that is not listed." 5. You write 8 documents a week, saving 12 minutes each. How many hours a week is that? 8 × 12 ÷ 60 = 1.6 hours.

Try this

You need an assistant and about forty-five minutes.

1. Choose three real pieces of writing from your week: one to draft, one existing draft to edit, and one finished text to shorten. 2. For the draft, write the facts list first. Prompt with purpose, reader, facts, shape and voice, plus your voice samples. Ask for the outline first, then the draft. 3. For the edit, choose the level deliberately. Run the matching prompt and ask for a list of changes. Review the list and reject at least one change. 4. For the cut, compute the share to remove with the simulator, name what must survive and run it. Then check every figure against the original. 5. Run the facts check on each output: list every number, date and name and confirm it against your source. 6. Score each output against this rubric, one point per yes. Check · Draft · Edit · CutFacts all correct? · · · Sounds like you or your organisation? · · · Right length and shape? · · · Free of stock phrases? · · · Sendable after light changes? · · · 7. Time yourself, compare with the time you would normally take, and use the habit simulator to estimate the weekly saving, counting the checking.

A good result is three pieces of writing that you would be content to put your name to, a list of the changes you rejected and why, and a saved prompt for each of your three jobs. In the next lesson we move from writing to reading: prompts for research, summaries and extracting facts from documents.
