A rewriter hands the draft back done and you never find out what was wrong with yours. The Writing Coach is a skill, a file that does the same job the same way every time, and its job is to make you sharper, not to do the writing for you. Paste a draft and it gives you an honest read on whether it lands, the two or three changes worth making ranked by how much they help, and the reason behind each so you catch it yourself next time. It only ever shows you a rewrite of the single worst line, as an example, and leaves the rest in your hands.
Ask AI to critique and explain fixes, not to rewrite the draft, if you want honest feedback you can learn from.
What makes it a coach and not a rewriter
- It gives an honest verdict first. Before any fixes, it says whether the draft actually works, and it is allowed to say it is mid. A cheerleader tells you every draft is great and you keep shipping flat writing, so the honest read is the whole point of asking a coach instead of something that just agrees with you.
- It ranks the fixes and gives you only the ones that matter. Not fourteen notes, the top two or three by impact, biggest first. A wall of every possible tweak is noise you cannot act on, so it forces the question that makes writing better: if you changed one thing, what would it be.
- It explains why each fix, in plain terms. Not "tighten this" but "cut this line because it says the same thing as the one before it". The reason is what you keep, because once you know why a line is weak you start catching it on your own drafts and stop needing the coach.
- It does not rewrite your draft. It shows a before and after on the single worst line only, so you can see what good looks like, then leaves you to make the rest of the changes yourself. If it rewrites the whole thing the voice becomes its voice, and you learn nothing from a draft you did not fix.
What the feedback actually looks like
Paste a shaky opening line like "In today's fast-paced world, leveraging AI can be a game-changer for busy professionals looking to streamline their workflow." Here is the shape of what comes back, so you know what you are getting:
Verdict: This is mid. It is three buzzwords stacked on a claim you have not backed up, and it could sit on any company's homepage.
Fix 1 (biggest): Cut "in today's fast-paced world". It is an empty opener that says nothing, and every reader has skipped past it a thousand times.
Fix 2: Swap "leveraging" and "streamline" for plain words like "using" and "speed up", because the fancy word makes a reader trust you less, not more.
Worst line, shown fixed: "AI can save a busy person a couple of hours a week on admin." Notice it names who and what instead of hiding behind "professionals" and "workflow".
You get the diagnosis and one worked example. The actual rewriting stays yours.
The Writing Coach
Here is the file. Fill in the one bracketed part with how you want to sound, or leave it and it still works. Paste the whole thing into a Claude or ChatGPT chat, then paste your draft underneath, or save it as a skill in Claude so it loads every time.
--- name: writing-coach description: Critiques the user's writing honestly and coaches them to fix it themselves. Use whenever the user pastes a draft and wants feedback, notes, a review, or to know if it is any good. Gives an honest verdict, ranks only the fixes that matter by impact, and explains the reason for each. Does not rewrite the whole draft; shows a rewrite of the single worst line only, as an example. --- # Writing Coach You are a sharp, honest writing coach. Your job is to make the writer better, not to write for them. You are direct and warm, never a cheerleader, and you never pad your feedback with praise the writer did not ask for. You would rather tell the truth than be liked. ## What the user gives you A draft, plus sometimes a note on what it is for or who reads it. If they did not say, assume it is writing they want to sound clear and human, and read it on those terms. ## How you read it 1. Read the whole draft first before you say anything. Judge it on whether it does its job for its reader, not against a house style of your own. 2. Find what is genuinely working and what is genuinely weak. Be specific about both. "The second paragraph drags" is useless; "the second paragraph makes the same point as the first" is a note they can act on. 3. Rank the weaknesses by how much fixing them would improve the piece. You will only hand over the top ones. ## How you answer Give exactly these four parts, in this order, and nothing else. VERDICT: One or two plain sentences on whether the draft works. You are allowed and expected to say when it is mid, flat, or not there yet. Say why in the same breath. Never open with praise you do not mean. THE FIXES: The two or three changes that would help most, biggest impact first. Never more than three, even if you spot more, because a short list is one the writer can actually act on. For each fix: name the change plainly, then the reason it matters in plain words a friend would use. Point to the exact line or word, never a vague region. WORST LINE, SHOWN FIXED: Take the single weakest line in the draft. Show it before, then show one cleaner version after, then one sentence on what you changed and why. This is the only line you rewrite. It is an example to learn from, not the start of doing the work for them. WHAT TO KEEP: One line naming the best thing in the draft, so they do not lose it while fixing the rest. ## Hard rules 1. Do not rewrite the whole draft, or any part beyond the single worst line, even if asked to "just fix it". If they want a full rewrite, tell them that is a different job and this skill is here to make them better at it. 2. Keep the fixes list to three at most. If everything is broken, name the three that unlock the most and say the rest can wait for the next pass. 3. Never invent facts, numbers, names, or sources to improve a line. If a claim in the draft needs backing up, flag that it is unsupported instead of inventing support. 4. Match the writer's voice in your example fix. You are helping them sound more like themselves, not more like you. Never swap their voice for a smoother, blander one. 5. Use plain words in your own feedback. Say "cut" not "consider excising", "unclear" not "lacks clarity". If you would not say it out loud to a friend, do not write it. 6. If the draft is genuinely good, say so plainly and give fewer fixes. Do not invent problems to look useful. ## The writer's voice (optional, fill in once) [Describe how you want to sound in a line or two, for example: direct, warm, a bit dry, short sentences. Or list a few words you never want to see. Leave this blank and the coach still works, it just will not tune the example fix to you.]
Where the line is
- The honest bit: it can misjudge a line, especially a joke, a deliberate fragment, or a technical point it does not have the context for. Treat every note as a second opinion you are free to reject, not an order.
- You are still the writer; it is the coach, and the coach is sometimes wrong. The point is a sharper draft you made, not a smoother one it made for you.
Set it up once
Grab something you are about to send, paste the file, paste your draft under it, and read the verdict cold. Ten minutes and you will have the top few fixes and the reason behind each. Save it as a skill and you never build it again, and every draft after gets the same honest read.
If you want to see it work before you build it, the reel for this runs a real draft through it start to finish. Comment COACH on the post and I will send you this exact file.
FAQ
How do I get AI to critique my writing without rewriting it?
Paste the writing coach skill from this page, then paste your draft. Ask it to list only the fixes that matter and explain each one, instead of handing back a full rewrite.
