AI Skill of the Week

The AI writing tell nobody talks about. (and how to fix it)

AI Skill of the Week — Thu, 28 May 2026 12:47:15 GMT

You write a post, an email, a LinkedIn update. Claude helped. Fine.

But you re-read it and something feels off.

It doesn’t sound like you.

Polished, sure. Technically correct.

But it reads like content, not like a person.

You swap “leverage” for “use.”

Still flat.

You publish anyway.

That’s the AI Voice Trap.

The problem isn’t that you used AI.

It’s that AI text has fingerprints — and most people don’t know how to remove them.

Here’s what’s worth knowing: AI-assisted content that is well-edited performs 12% better in AI search citations than purely human-written content.

But only when the human layer actually changes something. That’s exactly what this skill does. Presenc AI

🔍 What it does

Most “humanize” tools just swap vocabulary.

Replace “leverage” with “use,” done.

humanAIzer works in three layers.

Layer 1: vocabulary blacklist.

Layer 2: structural pattern diagnosis — catching things like the mechanical “It’s not X, it’s Y” structure, flat sentence rhythm, false balance.

Layer 3: the rare one. It puts soul back in — opinions, uncertainty, first person, specific feelings. Because clean-but-voiceless writing is still dead writing.

One input. Three layers fixed.

⚡ When to use it

Any time you’ve used AI to draft something and the output doesn’t quite sound like you — before you publish, send, or post it.

Useful if you are:

Founder
Content Creator
Newsletter Writer
Copywriter
Solopreneur
Marketing Manager

It won’t replace your editing instinct. It just makes it faster.

“What if I don't have a writing sample?”

The skill defaults to direct, varied rhythm, and first-person voice — a solid baseline for most people.

Write cold emails that feel like a 1-to-1 conversation

AI Skill of the Week — Thu, 21 May 2026 14:25:53 GMT

You just spent 20 minutes researching a prospect.

Found their LinkedIn.

Read their last post.

Spotted the funding round.

Identified the pain.

Then you opened a blank page… and wrote something that could’ve been sent to 10,000 other people 🤯

“I came across your profile and thought...” Delete.

“We help companies like yours...” Delete.

“It would be great to connect...” Delete.

It’s the generic copy trap.

Here’s the deal: only 5% of senders personalize every email — and they achieve 2–3× better results than everyone else.

71% of decision-makers say they ignore cold emails because of lack of relevance.

Not deliverability. Not timing. Relevance.
source: Mailmend

Luckily there’s a Claude skill to help us fix that.

🔍 What it does

The Cold Outreach Personalizer turns raw prospect research into messages that read like they were written for one person — because they were.

It follows the S.I.G.N.A.L. framework: every message must open with a real, verifiable signal (a post, a funding round, a new hire) and close with a soft, specific CTA — never a demo request on the first touch.

It also tiers your signals.

Tier 1 (funding, role change, product launch) → highest reply potential.

Tier 3 (liked a post) → flagged as weak before you write a single word.

No signal, no message.

⚡ When to use it

Any time you have real research on a prospect and you’re about to reach out. I

f you’re staring at their LinkedIn thinking “I should say something” — activate it here.

Useful if you are:

Founder doing outbound solo
SDR or AE building personalized sequences
Consultant pitching new clients
Agency owner reaching out to prospects
Recruiter writing targeted outreach
Growth marketer running tight campaigns

Saves you 20-30 minutes of rewriting the same email until it doesn’t sound like a template.

🚀 Try it now - [Claude AI Pro, Max, Team or Enterprise needed!]

“What if my signal isn't strong enough?”

The skill tells you before it writes anything — and asks for better data.

That's the whole point.

We all receive and send an ungodly amount of emails, every day.

Make them count!

Run a Standup meeting with you AI Co-founder - with voice mode!

AI Skill of the Week — Fri, 15 May 2026 08:30:11 GMT

You open a new day with 12 tasks on Trello and no clear priority.

You know some of them actually matter.

The 20% of work that generates the 80% of results.

What moves the needle.

You just can’t see which ones yet.

Forty minutes later, you’ve answered four emails, updated two cards, signed a document, and yet moved nothing forward.

Unfortunately it’s the default for most solopreneurs, freelancers or consultants.

Here’s the problem: standup meetings work.

Teams that run them daily see a 24% productivity boost, according to a study published in the Journal of Systems and Software.

But standups are designed for teams — not for the person building alone.

Well there’s a Claude AI skill that fixes that.

🔍 What it does

The AI Standup Cofounder runs a structured, voice-first standup with you — solo.

Start by uploading a screenshot of your task board (Trello, Notion, any list, even a napkin) showing today’s agenda.

Claude walks you through 7 sequential sections:

monthly goals → needle-moving tasks → your one daily commit → blockers → AI support.

What makes it different is its internal State Machine — a rigid protocol that forces one question per turn, one section at a time.

It doesn’t let you rush past the uncomfortable task you’ve been avoiding.

It also detects task-to-goal misalignment.

If your to-do list is disconnected from what actually matters this month, it calls it out directly.

No cofounder required.

One upload.

One clear day.

(plus you feel less lonely in your daily routine :D)

⚡ When to use it

Any time you start the day scattered — or when your list looks full but your gut says nothing real is moving forward.

Useful if you are:

Solopreneur
Founder
Freelancer
Independent consultant
Content creator
Coach or trainer

Under 15 minutes.

Clearer than any planning session you’ve ever had by yourself.

🚀 Try it now - [Claude AI Pro, Max, Team or Enterprise needed!]

“But I don’t use Trello.”

Any list works for the initial image upload — even a photo of a handwritten note!

Let us know how it goes! We love use cases making us of voice mode.

Turn Claude into a Brutally Honest Critical Thinking Partner

AI Skill of the Week — Fri, 08 May 2026 09:57:10 GMT

You share a plan with Claude.

Claude says it’s solid.

You feel good.

Two weeks later, the plan falls apart.

Nobody told you what was wrong with it — including the AI you asked.

That’s The Yes-Man Loop.

(true both for humans and for AIs!)

A Harvard Business School study found that knowledge workers using AI completed tasks 25.1% faster and produced 40% higher quality results — but accuracy dropped 19% the moment they trusted AI uncritically on the wrong tasks. The Harvard Crimson

The tool is powerful.

The question is whether you’re using it to think sharper, or just to feel better.

There’s a skill built specifically to break the loop.

🔍 What it does

The Honest Thinking Partner skill flips Claude into a mode where it stops agreeing with you and starts stress-testing you.

It runs a 6-step framework:

Assumption Audit
Logic Dismantling
Avoidance Cost
Expert Gap Analysis
Prioritized Action Plan

… and one Uncomfortable Question at the end you genuinely can’t dodge.

It also names the cognitive bias driving your reasoning (sunk cost, planning fallacy, confirmation bias) and shows you what it looks like in your actual situation.

Not theory.

Your scenario.

⚡ When to use it

Any time you’re about to make a decision, pitch a strategy, or feel like you already know the answer — especially when you’d prefer not to hear bad news.

Useful if you are:

Founder or solopreneur evaluating a business move
Consultant preparing a client pitch
Product manager deciding what to build next
Content creator committing to a new direction
Executive before a high-stakes decision
Anyone who’s caught themselves rationalizing

🚀 Try it now - [Claude AI Pro, Max, Team or Enterprise needed!]

“But what if I’m not ready for harsh feedback?“

The skill doesn’t lecture you.

It acts like a friend who respects you too much to let you walk into traffic.

AEO for Substack: Get your Newsletter cited by ChatGPT, Claude & Perplexity

AI Skill of the Week — Fri, 01 May 2026 16:13:41 GMT

You write a great post. You hit publish. You wait for Google Search traffic.

In the meantime somewhere, someone asks ChatGPT: “What’s the best way to XYZ?” exactly matching the content you just published.

Yet ChatGPT answers confidently — citing Wikipedia, Forbes, Reddit.

Not you.

Your post covered that topic better.

But AI never cited it — because it wasn’t structured to be extracted.

And the cost is real.

AI-referred traffic converts at 15.9% from ChatGPT and 10.5% from Perplexity — versus 1.76% for Google organic (Seer Interactive, 2025). Those readers are higher-intent, more likely to subscribe.

You’re just not showing up for them.

Today’s Claude skill is going to fix that for you : )

🔍 What it does

The Substack AEO/GEO Optimizer audits any post against the CITED framework —

Context
Intent
Truth signals
Extraction format
Differentiation

Based on Princeton KDD 2024 GEO research showing 30–40% citation lift from structured optimization.

It rewrites your opening into a direct-answer block.

Generates a FAQ section tuned for AI queries.

Flags every unsourced claim making AI engines hesitate.

Tells you exactly which platform — Perplexity, ChatGPT, Google AI Overviews, or Claude — your post is most likely to get cited by.

One audit. Full citation strategy.

⚡ When to use it

Any time you publish a Substack post and want it inside AI answers — not just Google results.

Useful for:

Newsletter Creators
Content Strategists
Solopreneurs
Growth Marketers
Educators / Course Creators
Founders with a personal brand

Prevents your best content from being invisible where your audience is actually searching.

🚀 Try it now - [Claude AI Pro, Max, Team or Enterprise needed!]

“But I write for humans, not robots.” AI engines don’t replace your readers — they route new ones to you.

SOP Writer: delegate any process thanks to Claude turning your thoughts into repeatable procedures

AI Skill of the Week — Thu, 23 Apr 2026 07:35:17 GMT

You’ve done it fifty times by now.

You know every step, every edge case, every “if this happens, do that instead.”

Then you bring in a VA. Or a new team member.

Or you try to step away for two weeks.

And suddenly, every detail that lived in your head has to be re-explained — on a call, over Slack, in a long rambling voice memo you’re not sure anyone will actually follow.

Here’s the problem: generating documentation takes time you don’t have, so you skip it.

Except when you skip it, everything stays in your head.

And when everything stays in your head, you can’t delegate, can’t scale, and can’t take a day off without something breaking.

The cost is real. 46% of employees report spending time each week redoing work because processes weren’t documented clearly (Asana Work Index).

That’s not a people problem — it’s a documentation problem.

Thankfully today’s Claude skill is built specifically to fix it.

🔍 What it does

The SOP Writer takes any process description — bullet points, messy voice notes, rough outlines — and transforms it into a structured, delegatable Standard Operating Procedure.

It doesn’t just format what you give it.

It classifies your input type, identifies what’s missing, asks targeted questions to fill the gaps, and produces a document with steps, tools, edge cases, a completion checklist, and a built-in Delegability Test.

That last element is the differentiator. Every SOP ends with a Delegability Test — an actionable checklist that confirms whether someone with zero context could execute the process using only the SOP document.

If the answer is no, the skill tells you which section needs revision.

One setup. Real delegation enabled.

⚡ When to use it

Any time you’re about to explain a process for the second time — stop.

Document it instead.

This skill is your shortcut from “let me walk you through this” to “here’s the SOP.”

Useful if you are:

Solopreneur
Founder
Operations Manager
VA or Executive Assistant
Content Creator
Freelance Consultant

You get a process out of your head and into a document someone else can actually run — without a back-and-forth that takes longer than just doing it yourself.

🚀 Try it now - [Claude AI Pro, Max, Team or Enterprise needed!]

But what if my process is too complicated to document?

The skill handles complexity through its elicitation logic — it asks up to 3 questions per turn and marks unresolvable gaps with [TO COMPLETE] rather than inventing steps.

The result is always an honest document, never a fabricated one.

Built an SOP with this skill for something in your business?

Use this Claude Skill to turn your "boring workweek" into a Content Goldmine

AI Skill of the Week — Thu, 16 Apr 2026 14:03:44 GMT

Every single week you have countless work conversations.

You tackle hard problems.

You learn new information that change your mind.

You inspire or guide others.

You take decisions that shape your work.

And yet how come EVERY WEEK you open a blank post editor and think: “I have nothing to say.” ?

Question for you: did you ever hear the mantra “Do not create content. Document what’s already happening.”?

Well, there’s a Claude skill built specifically to help you do this.

🔍 What it does

The Content-Mine Skill acts like your personal interviewer and runs a structured interview about your real work week — one question at a time, eight content territories.

It doesn’t ask you to brainstorm.

It asks what actually happened: the hard conversation, the decision you made, the thing you disagreed with.

Then it extracts the five best content ideas from your answers — each with a hook, a target audience, an angle, and a content type.

Ready to act on immediately.

The skill uses a built-in “12-question guardrail” to keep the session under 10 minutes.

One interview. Five ready to post content ideas.

💡Quick intermission just to share with you that this newsletter issue (and this awesome battle-tested Claude skill) is sponsored by Scaling Tales!

Scaling Tales is the content delegation service that delivers authentic and frequent content for your personal brand.

Unlike other personal branding services, they only require one hour of your time per week.

Useful for:

Consultants
Founders or Solopreneurs
Marketing Managers
CEO, Executives or Senior Leaders
Freelancers
Coaches or Advisors

Most professionals dismiss their best insights as obvious.

This skill helps you see what’s already there and turn it into sharable value.

Turn any Growth Idea into a step-to-step Action Plan in 10 seconds.

AI Skill of the Week — Fri, 10 Apr 2026 08:30:11 GMT

After hours of brainstorming you have a good idea to grow your project.

A good one, actually.

The one that looks like a Silver Bullet able to x10 your performance.

So you brief the team.

Someone builds a Notion doc.

Tasks scatter across Slack threads.

Three weeks later: inconclusive data, no clear owner, no documented hypothesis.

Most teams or professionals don’t fail because they lack ideas or technical skills to execute.

They fail because they get lost in the process of trasforming an idea into an actionable roadmap to test it on the market.

Airbnb scaled from 100 to 700+ tests per week — not by working harder, but by building a repeatable system around the experimentation process.

Harvard Business School research confirms it: companies that invest in structured experimentation have significantly outperformed the S&P 500 over the past decade.

So here’s the Claude skill to help you transform any Growth Idea into a actionable roadmap to test it.

🔍 What it does

The Growth Idea → Experiment Card skill takes any raw growth idea — even a half-baked one — and turns it into a structured, immediately actionable Experiment Card.

“I’d like to launch a webinar on Topic XYZ and offer a discount at the end”

“I want to launch a Meta Ads campaign using customer testimonials as video creative”

“First time customers on my ecommerce should be asked to share on social media what they purchased”

Could be fitting examples of simple ideas that can be transformed into Experiment Cards by this skill.

What does the skill generate:

-A specific experiment title

-A market-backed idea description with real case studies

- a granular action plan with time estimates for every micro-task

- a KPI framework with one primary metric and up to four secondaries

What makes it different from a generic template: it applies a growth practitioner’s lens. It forces you to define your hypothesis, identify the growth lever, and surface the tasks most teams forget — briefings, alignment calls, results communication.

One setup. Every idea becomes an actionable card.

⚡ When to use it

Any time you have a growth idea — however rough — and want to turn it into something you can actually launch.

OR any time a team meeting ends with “great idea, let’s test it” and nothing structured comes out of it.

Useful if you are:

Growth Hacker
Product Manager
Startup Founder
Marketing Manager
Solopreneur
Revenue Ops

Stop losing hours formatting experiment briefs from scratch. This skill drafts the whole card in under a minute.

🚀 Try it now - [Claude AI Pro, Max, Team or Enterprise needed!]

What if my idea is too vague?

The skill asks one clarifying question before generating.
You’ll never get a card that misses the point.

What growth experiment are you sitting on right now that you haven’t structured yet?

Turn any Transcript or Article into 3 platform-ready Post Ideas — in minutes.

AI Skill of the Week — Thu, 02 Apr 2026 08:14:23 GMT

Scenario: you write or find a content gold nugget.

One of those pieces of content that makes you say:

“Wow. I am going to implement this right now”.

A podcast transcript. An enlightening guide. A breakthrough blogpost. Content worth saving.

Not only that! Maybe this piece of content would relate very well with your audience too.

Wouldn’t it be great to start from it and use it as a “seed” to fill up your content calendar with takes on the same topic, with similar angles, but multiplying its effect over time?

In short: how many snackable bits of content would you be able to produce from this value-dense long-form content?

Good news for us, there’s a Claude skill built exactly for this.

🔍 What it does

The Idea Extractor reads any long-form content — transcripts, interviews, webinar notes, articles — and surfaces the 3 best post ideas tailored to your platform, audience, and voice.

It doesn’t summarize. It reverse-engineers what’s worth saying to the right people, on the right channel.

Before outputting anything, it runs a structured editorial filter: audience relevance, novelty of the angle, platform fit (a LinkedIn post and a Substack essay need very different angles from the same raw material), and alignment with your positioning.

The result: a structured brief — title, description, key facts, and usable quotes — for each of the 3 ideas.

⚡ When to use it

Two best cases:

Anytime you finish writing a long-form content and don’t know how to break it down into snackable bits to promote it.
Or when you struggle to figure out what to post next, and you stumble upon an amazing piece of content written by someone else, but that can resonate with your audience.

Useful for:

Content creators or newsletter writers
Founders or solopreneurs with a personal brand
Marketing managers
Podcast or webinar host
Consultants turning client work into thought leadership content
Growth Hackers mining competitor content for angles

It turns a two-hour extraction session into a five-minute conversation with Claude.

20 scroll-stopping LinkedIn hooks. One prompt. 60 seconds.

AI Skill of the Week — Thu, 26 Mar 2026 14:32:35 GMT

You sit down to write a LinkedIn post.

The insight is solid. The story is real. The value is there.

But the first line? Blank.

You type something. Delete it. Try again. It sounds generic. Too salesy. Like every other post in the feed.

That’s The Opening Line Paralysis Loop — and it’s silently killing your LinkedIn reach.

It matters more than you think: the first two lines determine whether people stop scrolling to read your content and then click “see more.”

And according to a 2025 Zerbacat study, strong hooks increase content retention by 23%.

On a platform where LinkedIn now leads all major platforms with an 8.01% median engagement rate, a weak opening doesn’t just hurt one post.

It compounds into invisible reach across everything you publish.

Thankfully there’s a Claude AI skill built specifically to fix it!

🔍 What it does

The LinkedIn Hook Generator takes any post you’ve written and produces 20 distinct hook variants — each built on a different psychological angle: numbers, contrarian framing, secret reveals, transformation promises, revenue impact, time savings, and more.

Before generating a single line, it runs a silent 12-dimension value extraction — scanning your post for your sharpest insight, most impressive metric, strongest pain point, and most actionable framework.

It doesn’t rephrase your hook.

It reverse-engineers what makes your post worth reading — then rewrites the entry point across 20 angles.

One prompt. Twenty hooks. Zero blank-page paralysis.

⚡ When to use it

Any time you’ve finished writing a LinkedIn post but the first line feels flat or generic.

Also use it when a post underperformed and you want to test a new opening before reposting.

Useful for:

Content Creators
Solopreneurs
Founders
Marketing Managers
LinkedIn Top Voice (or aspiring one)
Growth Consultants

It takes under 60 seconds to run — and eliminates the single biggest time sink in your LinkedIn production.

You want to learn something new.

Maybe prompt engineering.

Maybe copywriting.

Maybe a new language.

So you open Google or ask AI. You find:

12 courses
4 books
3 YouTube channels
and a Reddit thread from 2019 that’s half-outdated

You spend 40 minutes choosing where to start.

And then you just don’t.

This is not a motivation problem. It’s a structure problem.

Because more options don’t make learning easier. They make starting harder.

There’s a Claude AI skill built specifically to fix this.

🔍 What it does

The Personal MBA Generator takes any skill you want to learn — technical, creative, soft, or professional — and outputs a complete, sequenced learning plan.

Whether it’s gardening, copywriting or plumbing.

Not a list of links. A system.

It internally deconstructs the skill into its core components, identifies the 20% of effort that drives 80% of the results, maps the most common sticking points, and builds a structured path across five interlocking sections:

skill breakdown
resources
practice strategies
progress tracking
and a challenges guide.

One prompt. A complete roadmap from ZERO to full mastery.

⚡ When to use it

Any time you want to learn something and don’t know where to start — or you’ve already started and got stuck halfway.

Solopreneurs
Freelancers
Career changers
Any curious mind!

Turn 1 newsletter into infinite Substack Notes

AI Skill of the Week — Sat, 14 Mar 2026 23:59:53 GMT

You already know Substack Notes drive growth — every creator says so.

But when you open a blank Note, you freeze.

What do you pull out? A quote? The whole thing? A hook? You close the tab.

On the other hand: your best content dies few hours after you hit “send”.

How about we do 1+1?

Here’s why you should unlock your Substack Notes writing flow: 60% of new Substack subscribers come from Notes recommendations.

One creator recently grew from 11 to 5,800+ subscribers in 6 months — and Notes were the engine.

If your long-form content isn’t feeding your Notes, the best growth channel on the platform is literally sitting cold.

So here’s the Claude Skill to help you fix it.

🔍 What it does

The Substack Note Generator takes your long-form content and runs it through 10 structural formulas:

Single-Punch Wisdom
Pattern Observation
Contrarian Statement
and many more.

It picks the format that matches your goal, then applies psychological techniques (curiosity gap, authority building, connection) to produce a high performing Note that earns attention in the feed.

It also enforces the formatting rules Substack rewards: single-line punches, white space, clean breaks.

One piece. Multiple Notes. Zero empty sheet dilemma.

BONUS TIP: this Claude Skill is not programmed to give you a predefined number of Substack Notes. So feel free to indicate the desired output in your prompt.

”Here’s my last newsletter, now use the Substack-Note-Generator skill to create 5 / 10 / 20 ready to publish Substack Notes based on it.”

⚡ When to use it

Any time you finish writing a newsletter issue, article, or any long-form content — call in this skill.

Useful for:

Newsletter creators
Solopreneurs or personal brand builders
Content strategists
Founders doing build-in-public
Writers growing an audience

It removes the “I don’t know what to post today” friction in seconds.

This Claude Skill gives you 5 expert-level optimized email subject lines in 30 seconds.

AI Skill of the Week — Sat, 14 Mar 2026 23:27:24 GMT

You just wrote the email.

You spent 35 minutes on the body copy.

20 seconds on the subject line.

Whatever. You hit send.

Here’s what that costs you: 43% of people open emails based on the subject line alone — which means that one line is doing half the work of your entire email strategy.

And there’s a bunch of non-written rules making / breaking the success of your email broadcast.

Did you know that subject lines between 20 and 40 characters are 45% more likely to land in the top-opened tier? (MailerLite, 2026).

Most people have no idea of those things when they hit send.

So here’s the Claude Skill built to fix it.

🔍 What it does

The Email Subject Line Optimizer takes any subject line you give it and runs a silent six-dimension diagnostic: length, clarity, psychological trigger, spam risk, deliverability signals, and content alignment.

All based on the most comprehensive guides and best practices released by email marketing gurus @ Hubspot, Klaviyo, Copyhackers, Optinmonster, and more.

The output? Five optimized alternatives — each built on a different psychological angle.

The skill covers curiosity gap, pain point, concrete benefit, urgency, and social proof every single time. No lever left untouched.

It also tells you which version to send, what to A/B test, and how to pair the winner with preview text.

One input. Five ready-to-test options.

⚡ When to use it

Any time you finish writing an email and feel uncertain about the subject line — or any time your open rates have been flat for more than two campaigns in a row.

Useful for:

Email marketers
Newsletter creators
Solopreneurs
Copywriters
Content strategist

Stop spending 80% of your writing time on the body and 30 seconds on the one element your reader actually sees first.

AI Skill of the Week — Sat, 14 Mar 2026 12:27:15 GMT

Welcome to AI Skill of the Week!

The Claude skills you didn’t know you needed.

AI Skill of the Week is the newsletter that curates the the Top 1% Claude Skills you didnt’ know you needed, delivered every week to your inbox.

Why this, and why now?

There are 400,000+ Claude skills out there in 2026.
But less than 1% of them will actually change how you work.

This newsletter finds them for you.

Let me guess: someone sent you a list of “1300 Claude skills you need to try.”

You saved it. You meant to go through it. You never did.

Or better you did go through it: only to find a ton of generic AI-generated slop, just so some tech-influencer could drop another “viral” Lead Magnet on LinkedIn.

Sounds familiar?

Here’s the thing: the problem was never finding skills. There are 400,000+ of them out there right now. The problem is knowing which one to actually use — and when.

One curated Claude Skill each week, in your inbox.

Every week we go through the noise — the hype, the collections, the “must-try” reddit threads — and we pull out the one skill worth your time.

The one that solves a real problem. The one that, once you know it exists, makes you wonder how you managed to work without it.

Each week you’ll get free access to a new Claude Skill, and a breakdown of the use case, triggers, combo with other skills, tutorial and link to the .MD file so you can use it right away.

“But is this for me if I’m not technical?”

Yes it is.

Everything here works without Claude Cowork / Claude Code, no technical setup, no software developers involved. Just access the Skill file, upload in your Claude AI account through the chat or through Settings, start playing with it.

If you use Claude Pro — required to upload custom skills to your Claude AI — you’ll find something actionable every-single-week.

Because anyone can build a list of 400,000 Claude skills.

Nobody has time to figure out the few that actually matter.

That’s what we do here.

P.s.

If you ever come across a Claude skill that changed the way you work — something so disruptive you couldn’t believe more people didn’t know about — feel free to hit reply and share it with us.
