What is Claude Skills for Marketing?
Claude Skills for Marketing is a £19 book plus a library of 40+ Claude skills for marketers. Each skill is a specification (purpose, inputs, process, outputs, and quality rules), organised across six layers from research to analysis, and designed to chain into pipelines with validation gates between stations.
Prompts describe requests. Skills describe work.
A prompt is a hope. A skill is a decision made in advance: what should exist, and what "good" looks like. When you hand the model a spec instead of a prompt, you retain intent. The model only fills in details. The book gives you 40+ of these decisions, already made, across research, strategy, planning, execution, quality assurance, and analysis.
Quality isn't prompted. It's manufactured.
Every drafting skill in the library has a critic from the quality layer. The Ad Copy Factory drafts; the Coherence Auditor scores it against your landing page. The Long-form Drafter writes; the Voice Enforcer flags every off-brand sentence with a severity rating. Thresholds are numeric: alignment above 90, coherence above 85, character counts as hard fails. Failing is normal. The loop is designed on the assumption that the first draft will not pass.
This page was written by that loop. The first draft didn't pass.
And the second brain?
The memory layer from the post (the Postgres-backed source of truth that every skill reads before it writes) is what we're building next, in public, on the newsletter. The book is the foundation it stands on: without skills that have typed inputs and outputs, there is nothing for a memory to feed. Start with the foundation.
Who this is for
Marketers who want to stop operating a chat window and start authoring a system. And builders reading over their shoulder: everything in the book is a template: swap the domain skills and the validation rules, and the same architecture works for law, accounting, sales, or teaching.
Questions
Do I need Claude Pro?
Yes. The skills run on Claude Pro, and the loop and pipeline patterns extend naturally into Claude Code.
Is this a prompt pack?
No. Prompts describe requests; skills describe units of work, with typed inputs and outputs that let them chain into pipelines.
Does it include the second brain?
Not yet. The memory layer is being built in public on the newsletter. The book is the foundation it builds on.
What exactly do I get?
The book plus the copy-paste skill library, delivered instantly via Gumroad. One payment, £19.
