The workflow converts a repeatable task into a packaged set of expert instructions that Claude can consult when a relevant request arrives. Start with one narrow outcome, such as writing a high-FOMO hook or solving a small marketing problem, and articulate the methodology Claude should apply. Ask Claude to generate the skill file, ensure the file is named skill.md, place it in a ZIP archive, and upload it through the skills area under capabilities. Claude can then compare future requests against its available skills and select the relevant one without always being explicitly directed. Test the uploaded skill on realistic inputs, inspect whether Claude applied the intended method, and refine the skill's content or naming when activation is inconsistent.

Core principles
- 01Encode repeatable expertise instead of rewriting instructions for every task
- 02Define the task and desired method precisely
- 03Package each skill in Claude's required file structure
- 04Test skills on realistic work before relying on them
- 05Use distinctive names to improve automatic skill selection
How to run it
- 1
Select a Repeatable Task
Choose a narrow task that recurs often enough to justify reusable instructions. Define the desired output and the expertise that should govern it.
Pro tip Begin with an easy-to-evaluate task such as generating hooks, reviewing copy, or solving a familiar class of problems.
Watch out A generic task definition can make the resulting skill difficult for Claude to recognize and activate.
- 2
Teach the Method
Prompt Claude with the rules, frameworks, examples, and reasoning process that constitute strong performance. Ask it to turn those instructions into a new skill.
Pro tip Include proven frameworks and clear quality criteria rather than requesting an undefined expert persona.
Watch out Basic prompts may produce usable demonstrations but will need improvement for consistently expert output.
- 3
Generate the Skill File
Instruct Claude to create the skill in the required format, then download the generated file. Confirm that its final filename is skill.md.
Pro tip Review the generated methodology before packaging it to catch vague or contradictory instructions.
Watch out An incorrectly named or formatted file may not upload successfully.
- 4
Package and Upload
Place skill.md inside a ZIP archive and upload that archive through Claude's capabilities and skills interface.
Pro tip Give the skill and archive descriptive names that clearly communicate the task they handle.
Watch out Uploading the uncompressed file or using the wrong internal filename can prevent installation.
- 5
Run a Realistic Test
Give Claude a representative input and ask for the target outcome. Check that it consults the uploaded skill and follows its methodology.
Pro tip Use a task with an output you can assess against concrete quality criteria.
Watch out A successful upload does not guarantee that Claude will select the skill for every relevant request.
- 6
Refine Skill Activation
If Claude does not select the skill reliably, invoke it explicitly and improve its name or task description. Repeat testing until selection and output quality are dependable.
Pro tip Prefer distinctive task-oriented names over broad labels such as problem or helper.
Watch out Do not assume a skill is production-ready after a single successful example.
In the wild
The host asks Claude to create a skill for writing hooks that produce fear of missing out. After packaging and uploading it, he supplies a post about language models predicting purchase intent and asks for a hook. Claude consults the skill, produces multiple options, identifies the formulas used, and explains why each hook works.
→ A recurring copywriting task becomes a reusable capability that produces structured hook options on demand.
The host creates a skill for handling small daily problems, then tests it on the challenge of promoting a Substack tutorial on LinkedIn without losing engagement to an external link. The skill analyzes the root cause and priorities before proposing options such as a LinkedIn article, carousel, first-comment link, or teaser.
→ Claude applies a consistent problem-solving methodology instead of returning a single unstructured suggestion.
Common mistakes
Using an Overly Basic Prompt
A shallow prompt may produce a functional skill but not the depth needed for expert-level output. Supply an explicit methodology, constraints, and quality criteria.
Packaging the Skill Incorrectly
The upload can fail when the file is not named skill.md, is not in the required format, or is not placed inside a ZIP archive.
Giving the Skill a Generic Name
Broad names can make automatic selection unreliable because Claude has difficulty matching the request to the intended capability.
Is it for you?
Best for
It is best for recurring, well-defined knowledge tasks whose quality depends on a consistent method or standard.
Not ideal for
It is not ideal for one-off requests, vaguely defined work, or tasks that cannot be reduced to reusable instructions.
From the transcript
“You can just go and ask Claude now to create skills and it knows what you mean.”
“You ask it to make sure it's in this format. Then you download it and then you have to zip it up and call it…”
“You don't have to tell it which one to use. It can actually figure that out itself.”
