AI changed who gets to build things. The hard part isn’t code now — it’s knowing what to do next. These are sixteen ready-made skills that tell your AI exactly that, drawn from real products and real mistakes.

Who this is for
For twenty years, having an idea wasn’t enough — you needed someone who could build it. That stopped being true. People are shipping real products now having never written a line of code.
But building was only ever half of it. The half nobody hands you is knowing what to do next: whether the idea is worth it at all, what an advert is really costing you, why people leave on day three, whether the thing you just changed actually worked.
That’s what these are. A skill is a recipe your AI follows — you write it down once and Claude works out when to use it. Eight of these sixteen need no technical knowledge at all. The other eight are for when you’re building. Both are marked below, so there are no surprises.
The sixteen
Three searches and four checks that catch what competitor research misses. Free below.
Work out what you really pay per result, and tell a dead channel from bad creative.
Tag before you post. What a big "direct traffic" number is actually hiding.
What a community is really worth, and how to buy a post without overpaying.
The two screenshots and the one line that do nearly all the work.
Averages will lie to you. This splits people by when they arrived.
Find the buttons, targets and states people genuinely miss on screen.
Design a single check that tests every layer, for problems on devices you don't own.
Simulate what the screen tells people to do, and check it actually wins.
Verify on the real site, not in your editor.
Shuffles and odds that aren't what they look like. Free below.
The technical foundation: canonical host, sitemap, social cards, structured data.
The part everyone gets wrong. Includes the certificate trick.
Why a fresh page loads old files, and how to make it impossible.
Let people use your app without an account, safely.
Exact-size banners and social cards from code. No design tools.
Why these are different
Three examples, all in the pack, all measured:
The instruction said "tap the side you're falling towards". The code pushed you in the direction you tapped — so it was telling players to speed up their own fall. Over 300 simulated runs:
| What you do | Times you fall |
|---|---|
| Tap the opposite side | 0 |
| Tap towards it — what the screen said | 1,108 |
| Don't touch anything at all | 1,108 |
Following the instructions was worth exactly as much as not playing. No difficulty tweak would ever have fixed it.
One line of code sits in a lot of projects: sort(() => Math.random() - 0.5). It looks like a shuffle. It isn't. Where the right answer actually landed, over 200,000 runs:
| Position | Should be 25% |
|---|---|
| First option | 28.3% |
| Second | 28.2% |
| Third | 24.7% |
| Fourth | 18.8% |
Always guessing the first option beat guessing at random. The same bug was in eleven places in one project.
Six communities, same market, all quoting for a post:
| Members | Posts a day | Your post is buried after |
|---|---|---|
| 801,000 | 54 | ~18 min |
| 130,000 | 12 | ~80 min |
| 50,000 | 7 | ~2.3 hrs |
| 21,000 (asking the most) | 117 | ~8 min |
Member count is the number sellers quote and the one that means least.
Not teasers — the complete files, same as the fourteen you'd pay for. If they're not useful, don't buy the pack.
Three searches and four checks, before you build anything.
The shuffle bug above, how to spot it, and how to test it properly.
