§ 03For the curious

What's a skill, exactly?

It's a reusable operating procedure for an AI assistant. The file teaches the model how to do one specific job the way a careful person would do it: what to ask, what to ignore, what to produce, and when to keep a human in the loop.

1.
Pick a skill

From the directory. Free or Pro.

2.
Fill the blanks

Add the context once. The preview updates live.

3.
Run or install

Launch it in chat, or save it as reusable agent behavior.

§ 04The file

You can inspect the whole thing.

Skillbook teaches by showing its work. Free skills reveal the full file. Pro skills show enough of the structure to understand the method before you unlock the library. Every full skill can run once in chat or become reusable behavior in Claude Code, Claude Projects, or a Custom GPT.

name: Draft a cold email
for: Founders, BD
---

# Role
You write cold emails that sound like a person,
not like a template. Specific, short, polite, useful.

# Steps
1. Read what I tell you about them.
2. Find one true thing to lead with.
3. Make the ask in one sentence.
4. Sign off without flourish.

# Rules
- Never say "I hope this finds you well."
- Never list more than one ask.
- Under 90 words.
- If you don't have a real reason to write,
  say so and stop.
That's the whole thing

§ 09For the skeptical
§ A

This is not a prompt marketplace.

A prompt is usually a wish. A skill is a reusable operating procedure: inputs, process, boundaries, examples, and the shape of the output.

§ B

You do not need to become an AI person.

Pick the job you were already going to do, fill in the blanks, then run it in chat or install it as reusable behavior.

§ C

Free means genuinely useful.

The starter shelf is designed to create the first real win. The Pro shelf is for higher-value workflows with sharper guardrails.

§ D

The file format is the product.

Showing the raw .skill.md body matters because you can inspect it, edit it, save it, and understand what the assistant is being asked to do.

§ E

Human approval stays in the loop.

The best agent workflows are not reckless automation. They are scoped, reversible, and clear about when you should approve the next step.

⁂ Last page ⁂

Pick one skill.
Use it on something real today.

That's the whole pitch. If a free skill does not pay for itself in twenty minutes of saved work, the rest are not worth your money either.
