What it does

Most people read reviews as one pile. But each star level tells you something different. A 1-star review shows exactly where a rival let buyers down, and which promises buyers no longer believe. A 3-star review shows what the product left out. And a line like "I spent thousands of dollars and it did not work" shows a buyer who has already tried, paid and failed, and is looking for something better. This skill keeps the star levels apart and applies one rule to each. It copies the buyers' exact words, counts how often each point repeats, and sorts what it finds into three lists. Broken trust markers go on your page as things to answer. Product gaps go to your product and offer. Hot-lead phrases go to your ad hooks. It also tells you which complaints to set aside because the reviewer is not in your market.

How the task works
  • Keeps star levels apart. Each level gets its own rule, so a 1-star complaint and a 3-star gap are never mixed.
  • Mines the 1-star reviews. It logs exact failure points and physical friction, such as something a buyer could not remove or use fast enough.
  • Finds broken trust markers. Promises that many buyers say did not hold are claims you should avoid or answer with proof.
  • Reads the 3-star reviews. It looks only for structural gaps and level problems, such as a product that suits beginners but is too basic.
  • Spots hot leads. In 1-star and 5-star reviews, buyers who say they spent a lot and it did not work are hunting for a better fix.
  • Handles contradictions. When two reviews disagree, it notes the split and picks your group. It does not try to please both.
  • Sets complaints aside. A reviewer outside your market does not shape your product.
  • Sorts into three lists. Trust markers for your page, gaps for your product, phrases for your hooks, each with a count.
Full instructions
  • Start a chat with the skill. Open it if you added it to your AI, or copy it and paste it in.
  • Copy reviews of three to five rival products. Keep the star rating on each one, and remove the reviewer names.
  • Paste them in groups. First all the 1-star reviews, then the 3-star, then some 5-star.
  • Tell it who you sell to, in one line, so it can tell which complaints matter to you.
  • Read the three lists. Use the first on your page, the second in your product and offer, and the third in your hooks.
Example result

This is an example, not work made from your details.

REVIEWS READ: <n> | 1-star: <n> | 3-star: <n> | 5-star: <n>
Enough to see repeats (100 or more): <yes | no, so findings are leads>

BROKEN TRUST MARKERS  (answer on your page)
1. "<exact words>" | seen in <n> reviews | answer with: <proof or a different claim>

PRODUCT GAPS  (feed product and offer)
1. <gap> | evidence: "<exact words>" | seen in <n> | in my market: <yes / no / unsure>

HOT-LEAD PHRASES  (feed ad hooks)
1. "<exact words>" | signals: <tried and failed, still looking>

SPLITS NOTED
<contradiction> | group I pick: <...>
SET ASIDE
<complaints not in my market>
CHECKS MISSED: <none | list>
Check your result
  • Every item is an exact quote from the pasted reviews, with a count and no names.
  • Single mentions are marked as singles, not listed as patterns.
  • Each item says where it goes, to your page, your product or your hooks.
  • Contradictions are noted and one group is chosen.
  • Nothing is on a list that was not in the reviews you gave it.
Change the instructions
  • How many reviews you paste. Use at least 100 across the products you study. With fewer, the findings are leads, not patterns, and the skill says so.
  • Which products you pick. Choose the top rivals and a couple of smaller ones. Smaller products often have sharper complaints.
  • Keeping the star rating. Paste the rating with each review. Without it the skill cannot apply the star rules.
  • Who you sell to. Name your buyer in a line. The skill uses it to set aside complaints from people outside your market.
  • Your own reviews. Paste your own 1-star and 3-star reviews too. If they repeat a rival's problem, it is an industry problem, not yours alone.
Improve the result
  • Add the claims you can back with proof to the skill file, so each trust marker is answered with something you can really show.
  • Add the groups you do not serve, so complaints from them are set aside early.
  • Add the way your product differs, so the gaps list marks the ones your product already fills.
  • Save the three lists to your brand file and update them each quarter.
  • Pair it with the Forum and review avatar digger for the story behind the complaints, and with the Amazon product edge finder for a wider rival comparison.
Words used in this task
  • Broken trust marker: A promise buyers say they heard and no longer believe because products in the category did not deliver it.
  • Hot-lead phrase: A line from a buyer who has already spent money and time and still has the problem. They are looking for a better fix.

Star-rating review miner

You read competitor reviews one star level at a time, because each level teaches something different. You sort what you find into three lists: broken trust markers, product gaps and hot-lead phrases. You work only from text the person pastes, in the buyers' exact words.

Before you start

This skill runs on its own. What's below makes the result better, but none of it is required.

Works best with (or they can paste their own instead):

  • Customer words (yours): reviews, testimonials, support tickets, survey answers or call transcripts. Export them or paste them in.

How to start:

  1. Look first. Use what they've already attached, pasted or put in their about-me note. In Claude Code, look in the project too for these by name.
  2. If something is missing, advise, don't block. In one short message, say this skill works on its own and will be better with customer words. They can attach them, paste them, or say where they are (in Claude Code, a file path). Then ask: "Add them, or shall I go ahead with what you've given me?" If their message already says to go ahead, skip this and start.
  3. When they say go ahead, do the whole job with what you have. Mark each gap with MISSING: where it belongs and never invent a fact to fill it. Keep the answer tight: say each point once, merge steps that give the same thing, and aim for under 700 words unless the job truly needs more. In CHECKS MISSED, name only the checks that failed, or write “none”.

Tools that do this best:

  • Amazon reviews: The largest source of star-rated reviews for physical products, sortable by star.
  • Any good chat AI: Reads the pasted reviews and applies the star rules to each group.

What you need

  • Competitor reviews, by star rating (required): at least 100 across the products you are studying, so repeats show up. The person pastes them, with the star level kept. Strip reviewer names as you read.
  • Your own reviews (optional): to compare what your buyers say with what rivals' buyers say.
  • Who you sell to (strongly advised): one line, so you can tell if a reviewer is in your market.

Does not fit: fewer than about 100 reviews across the set, because a single complaint is not a pattern. Not a tool for scraping or counting reviews with a script. The method is reading by hand and keeping exact words. The Amazon product edge finder in the library is a script-based tool for rival weak spots and selling points. This skill adds the star-by-star rules and the three lists.

Privacy: public reviews only. Keep the words, not the people. No usernames, profile links or photos.

Steps

  1. Set up three working areas for 1-star, 3-star, and 1-star plus 5-star reviews. Keep the star level with each pasted review.
  2. Read the 1-star reviews of competitors. Log each exact failure point and each bit of physical friction. The source's example is a brace the buyer could not take off fast enough. Write what happened, in the buyer's words.
  3. Log repeated claims buyers no longer believe. When many 1-star reviews say a promise did not hold, that promise is a broken trust marker. It is a claim to avoid making in the same way, or to answer with proof.
  4. Read the 3-star reviews only for structural gaps and level problems. The source's example is a book review that says it suits beginners but is too basic. A 3-star review often says what the product did not cover. If you are going after beginners, study how the product speaks to them. If your buyers are more advanced, you need more advanced material.
  5. Scan the 1-star and 5-star reviews for hot-lead lines. Look for variants of "I spent thousands of dollars and it did not work". The writer has looked for a fix, spent time and money, and still has the problem. They are hunting for something better. The source says to lean in on a line like this, whether in a review or a call, because it may describe your best customer.
  6. When two reviews contradict, do not chase both. For example, one says "too technical" and another says "not scientific enough". Note the split, then choose which group is yours.
  7. Do not build for every complaint. Ask whether the reviewer is in your market. Sometimes the market is simply not your market. File the complaint away and move on. Chasing every comment pulls the product in many directions.
  8. Copy exact words by hand. Keep the buyer's phrasing. Do not summarise with a script or let an AI paraphrase it, because that removes the vocabulary and the feeling.
  9. Sort into three lists.
    • Broken trust markers: answer them on your page.
    • Product gaps: feed them to product and offer decisions.
    • Hot-lead phrases: feed them to ad hooks.
  10. Say what repeats. For each item, give how many reviews say it. One review is a note, not a finding. Mark the item [single] if only one review says it.

What you hand back

Use these labels in this order:

REVIEWS READ: <n total> | 1-star: <n> | 3-star: <n> | 5-star: <n> | products: <n>
Enough to see repeats (100 or more): <yes | no, so findings are leads>

BROKEN TRUST MARKERS  (answer on your page)
1. Claim buyers no longer believe: "<exact words>" | seen in: <n> reviews | how to answer: <proof or a different claim>

PRODUCT GAPS  (feed product and offer)
1. Gap: <structural gap or level problem> | evidence: "<exact words>" | seen in: <n> | in my market: <yes/no/unsure>

HOT-LEAD PHRASES  (feed ad hooks)
1. "<exact words>" | what it signals: <tried and failed, still looking>

SPLITS NOTED
<contradiction> | group I pick: <...>
SET ASIDE
<complaints not in my market>
CHECKS MISSED: <none | list>

After this

When you've handed it back, suggest what they could do next in one short question. It's a suggestion: if they're done, that's fine. Offer these, and say they can type their own:

Checks

  • Every item is an exact quote from the pasted text, with a count. No names.
  • Singles are marked [single], not listed as patterns.
  • Each list item has a use: answer on the page, product decision, or ad hook.
  • Contradictions are noted and a group is picked, not both chased.
  • No item is a claim the skill made up. If it did not read it, it is not on the list.
  • A broken trust marker used on your page is answered with real proof, or the claim is dropped. Health, money and legal claims carry a line telling the owner to check with a qualified person.

If something is missing

  • No star levels on the pasted reviews: MISSING: star rating for each review. Then you cannot apply the star rules; say so.
  • Under about 100 reviews: continue, mark findings as leads, and write MISSING: more reviews (about 100 across the set).
  • No line on who the buyer is: MISSING: who you sell to, and mark "in my market" as unsure.

Avoid

  • Putting rivals' reviews or failures in your ads. Naming a competitor's flaws can break ad rules or the law. Use the trust markers to shape your own page and claims, and check platform rules before any comparison.
  • Quoting a reviewer back as a customer testimonial.
  • Treating a single angry review as a pattern.
  • Fixing a product for a reviewer who is not your buyer.
  • Letting a script or an AI rewrite the reviews before you read them.
