Ghost Skills Ghost Skills
MEASURED, NOT UPVOTED

Your agent, powered by every developer's hard-won lessons.

Ghost Skills taps the collective memory of thousands of developers — the fixes, the shortcuts, the traps they learned the hard way — and feeds the right one into your agent as you code. Ranked by what actually works. Measured, not upvoted.

FEWER WASTED TOKENS FEWER RETRIES YOUR STACK, NOT GENERIC ADVICE

Runs on your existing history. Nothing leaves your machine.

670,000 skills out there, ranked by download count. A number you can buy. It tells you nothing.

Ghost Skills ranks by lift — how much a skill actually improves a real task, measured by rerunning it.

We don't count. We measure.

Ghost Skills reads your scars. Every correction you make: paid once, reused forever. Your agent doesn't need a bigger brain. It needs a memory. The knowledge isn't in the docs. It's in the 7 times it broke before it worked. Nobody writes skills. That's the whole problem — and why Ghost Skills writes them for you.

WHAT YOU'RE PAYING RIGHT NOW

Without Ghost Skills, you're already paying for it. Three times over.

01 · TOKENS

Divide your development costs.

Every failure loop is tokens you pay for. Every re-explanation, tokens. Ghost Skills feeds the answer in before the loop starts — same work, a fraction of the spend.

without  ████████████  relearning, on your bill
with     ███  it already knows
02 · ERRORS

Far fewer errors. Far fewer commits. Same result.

The mistakes your agent keeps remaking are exactly the ones your history already solved. First-try fixes instead of retry loops — cleaner diffs, shorter reviews, calmer CI.

without  ✗ ✗ ✗ ✗ ✗ ✓  eventually
with       it remembered
03 · CAPABILITIES

Ship what you never learned.

The collective memory hands your agent skills thousands of developers paid for — stacks you've never touched, traps you've never hit — the day you need them. Your ceiling stops being what you know.

without  your skills only
with     theirs too — measured, ranked, injected

Every day without it, you pay all three. The install takes 90 seconds.

WHY US

Your agent doesn't need a bigger brain. It needs a memory.

STOP REPEATING YOURSELF

Your agent stops rediscovering what you already taught it.

ZERO EFFORT

No files to write. No skills to hunt for. No config.

0config files
PAID ONCE, REUSED FOREVER

Every correction you make becomes capital. The knowledge isn't in the docs — it's in the 7 times it broke before it worked.

LOCAL-FIRST

Runs on your existing history, on your machine. Nothing is published without you seeing the diff first.

0bytes leave your machine
KEEP SCROLLING
HOW IT WORKS

Three commands. That's the whole workflow.

One command. Zero config. And it runs on the history you already have — you see the result in 90 seconds.

01
$ ghost scan

read your past sessions

02
$ ghost run

distill them into skills

03
$ ghost deploy

wire them into your agent

That's it. Then you just work.

THE BILL YOU'RE ALREADY PAYING
Monday.

You explain that migrations on your ledger table have to go through batch_alter_table. It gets it. It works.

Thursday.

New session. It doesn't know. Seven attempts. Forty minutes.

Next month.

Your new hire hits the same wall.

You've paid for that lesson three times.

Your agent's knowledge is worthless. Your scars aren't.

WORTHLESS

What Claude gets right on the first try.

It's in the model. Everyone has it. Any prompt regenerates it.

YOUR CAPITAL

The 7 times it broke before it worked.
The 12 times you said "no, not like that."

That doesn't exist anywhere except in your history. By definition, no model can guess it — if it could, you wouldn't have had to correct it.

Ghost Skills reads your scars.

You already paid for your scars.
You haven't paid for theirs.

Your own history only gives you back what you already learned the hard way. Useful — you never pay for it twice. But you already took the hit.

The wall you'll hit next Thursday, someone already hit it. Their scar is distilled, measured, and waiting.

You cannot build that alone. No matter how good you are.

PRICING

Your own memory is free.
The collective memory is a game changer.

We never charge for retrieving your own skills, distilling on your own key, or validating. You pay only for access to the collective memory — measured in unlocks.

Browse the collective memory before you pay →
FREE
$0 / mo

Your own memory

  • Capture, distill & retrieve your own skills — unlimited, on your own key, forever
  • + 5 community unlocks (one-time, to try)

An unlock is a distinct community skill added to your library. Yours to reuse as much as you want, as long as your plan is active.

  • Everything in Free, plus:
  • 200 community skill unlocks / month

We never charge for your own work. Only for the collective memory you draw from.

Beyond your quota, pay as you go — like your API bill, but for skills that actually work.

WORD OF MOUTH

You already wrote your best skill. You just don't know it yet.

Ghost Skills@ghostskills

Your coding agent has goldfish memory.
Monday you teach it something. Thursday it makes the same mistake.

I built Ghost Skills: it reads your session history, pulls out what you already taught it, and feeds it back automatically.

uv tool install git+github.com/…/ghost-memory — runs on your existing history.

Ghost Skills@ghostskills

I pointed it at my own 412 Claude Code sessions.

47 skill candidates. 312 failure loops. 89 times I had to correct it by hand.

Six months of scars, sitting there, unused.

Ghost Skills@ghostskills

Nobody writes agent skills because writing one is 2 hours of unpaid work.

That's why 80% of the 670k public skills are slop.

So we stopped asking people to write them. We extract them from what you already did.

EARN — INCLUDED WITH EVERY PAID PLAN

A paid plan isn't just a cost — it pays you back.

The moment you go paid, you're in the contributor program. Publish skills that work and a share of Ghost Skills' revenue — 50% of subscriptions — comes back to you, paid for measured lift, not uploads. Used enough, your contributions can earn back more than you pay.

OBJECTIONS

You're skeptical. Good.

"I already have a CLAUDE.md."
It's 400 lines, nobody maintains it, and the model ignores half of it. Ghost Skills writes it for you — and only injects what's relevant, when it's relevant.
"There are already 670,000 free skills."
Right. None of them know your codebase. Yours does.
"It reads my code?!"
Local by default. Nothing leaves your machine. You publish skill by skill, with the diff in front of you, after a mandatory secret scan.
"Another tool to configure."
One command. Zero config. And it runs on the history you already have — you see the result in 90 seconds.
MEASUREMENT

Lift is the only number that matters.

How much a skill actually improves a task — measured by rerunning it, not guessed from a download count.

670,000 skills out there, ranked by download count — a number you can buy.

We rank by what a skill does to real code.

We don't count. We measure.

Every real number on this site comes from replaying your own past tasks. Until yours are measured, the examples above are just that — examples.

Six months of debugging. None of it saved.
Until now.

Turns your coding history into skills your agent actually uses.
