Prompt Engineering Playbook: A Trained Agent for One Ad Account

The Prompt Engineering Playbook is a set of agent files generated from one of your ad accounts — its campaign structure, spend history, and current state — and handed to you as a download you install in your AI client. It answers the question people ask after connecting Adspirer: “the tools work, but how do I actually get good at this?” Instead of you learning prompt engineering, the playbook writes the prompts, the instructions, and the account briefing for you.

The single most important thing on this page: this is a one-time purchase, not a subscription. You pay $39 once for a given ad account and nothing recurs — no monthly charge, no renewal, no second bill. It is separate from your Adspirer plan, which continues to work exactly as before. The files are yours to keep, and rebuilding them later is free and unlimited.

What it is — and what it is not

Adspirer ships 13 free Agent Skills that teach any assistant how to run ads in general: how to structure a Google Search campaign, what Meta needs before a launch, the safety rules. Every plan gets those, at no cost. The Prompt Engineering Playbook is the layer above that. It is not general advertising knowledge — it is your account, written down.

	Free Agent Skills	Prompt Engineering Playbook
Scope	Advertising in general	One specific ad account
Knows your campaigns	No	Yes — read from the live account
Knows your spend and currency	No	Yes
Cost	Free on every plan	$39 once, per ad account
Who writes it	Adspirer, for everyone	Generated for you, from your data

You want both. The free skills are the grammar; the playbook is the briefing.

What you get

The download is a .zip laid out to the open Agent Skills format, so the same folder works across clients. One zip, one folder, flat inside — only references/ nests, because that’s the spec’s progressive-disclosure mechanism (those files load on demand instead of on every activation):

<platform>-expert-<your-account>/
├── SKILL.md                             # the operating doctrine, pinned to your account
├── AGENTS.md                            # your account's instructions, in the agents.md standard
├── PROMPTBOOK.md                        # the prompt book, organized by level and workflow
├── README.md                            # where each piece goes, per client
└── references/
    ├── account-profile.md               # the dossier — your account's state and priorities
    └── working-with-adspirer.md         # how the agent should call Adspirer's tools

File	What it does	Where it goes
`SKILL.md`	The agent’s operating doctrine for this account. Loads automatically when you ask about this account — you never invoke it by name.	Uploaded or dropped in as a skill
`AGENTS.md`	The constitution — the account-pinned rules, in the agents.md standard. Read automatically by folder-based clients, and the text you paste into a chat client’s instructions field.	Project root for coding agents; instructions field for chat clients
`PROMPTBOOK.md`	The starting prompts — organized by level and workflow, written against your campaigns.	You read and copy these
`README.md`	Says where each piece goes, per client, so the folder explains itself once unzipped.	You read this
`references/account-profile.md`	A written dossier of the account: what state it’s in, what to prioritize, what cadence to work on.	Read by the agent on demand
`references/working-with-adspirer.md`	The tool-calling contract and guardrails: discovery loop, read-before-write, pause-don’t-delete.	Read by the agent on demand

There is one instructions file, and it’s AGENTS.md. Earlier kits also shipped a separate AGENT_INSTRUCTIONS.md with identical text; it was dropped as a duplicate. Coding agents read AGENTS.md from a project root automatically, and for chat clients the kit page has a one-click Copy instructions button that puts the same text on your clipboard. Kits you downloaded before this change still work — keep using the file you have.

PROMPTBOOK.md is a menu, not a script. Your agent is told to open it to suggest a sensible next step or to find the right approach for something you asked for — then run only that one. It will not work through it start to finish, because every prompt in it spends real tool calls.

How it’s built

When you buy, Adspirer runs a five-stage build against the live account. It usually finishes in a few minutes, and the page shows each stage as it completes:

Reading account structure

Pulls the campaigns, ad groups, budgets, and settings that exist right now.

Classifying the account's state

Works out what kind of account this is — scaling, stalled, newly built, seasonal.

Writing the account dossier

Writes account-profile.md: the state read, the priorities, the working cadence.

Writing your prompt book

Writes PROMPTBOOK.md against your actual campaigns and currency.

Assembling the skill package

Builds the folder, validates it against the Agent Skills spec, and packages the .zip.

If a build fails, the kit page shows it and offers a retry. A failed build costs you nothing extra.

Price

	Price	Billing	Covers
Prompt Engineering Playbook	$39	One time — nothing recurs	One ad account

Priced per ad account, because it is generated from that account’s data. Two accounts means two playbooks.
Select every eligible account and 20% comes off the whole cart. Tick them all in Expert Space — the cart bar has a Select all shortcut — and the bundle discount applies automatically at checkout. It needs at least two accounts, and it has to be all of the ones you can still buy; a partial selection pays full price per kit. The cart always shows the live discount before you pay.
Buying several is a single checkout and a single charge, not one payment per account.
Annual plans include one playbook free. If you’re on an annual plan, claim it from Expert Space — there’s no checkout step and no charge.
The add-on also appears as an optional “Add to your order” on plan checkouts. Adding it there charges the $39 immediately, on the same invoice as your plan — which is why the line item reads “One-time Agent Setup — 1 Ad Account”.

**Seeing

39 next to your plan charge does not mean your plan went up.** If you took the add-on during checkout, the

39 sits on the same invoice as your subscription, as a separate one-time line. Your recurring plan price is unchanged, and the $39 will not appear on next month’s invoice. Your billing page shows the recurring amount on its own.

Because each playbook is generated on demand from your account, it’s non-refundable once the build has completed and the files are available to download. If a build failed, or you were charged for an account you can’t access, contact support — that’s a different situation and we’ll sort it out.

How to get it

Open Expert Space

Go to adspirer.ai/expert-space. You’ll see one card per connected ad account, grouped by platform.

Pick the account

Cards show what the playbook will be built from — campaign count, months of history, currency. Accounts that aren’t active show Inactive; activate them in Connections first.

Preview, then buy

Preview Expert shows sample prompts before you pay. Buy one account, or tick several and check out together.

Wait for the build

A few minutes. You can close the tab — the kit keeps building.

Download the .zip

From the kit page: Download. You can also hit Copy instructions to put the agent instructions straight on your clipboard, read the prompt book in the browser, or download the prompt book on its own as a .md file — handy for pasting into a doc or dropping beside a project without unzipping the whole kit.

Lost the link? Everything you’ve bought is always at adspirer.ai/expert-space — owned accounts show an Open Kit button. The purchase email also carries a direct link, but you never need it.

Install it in your AI client

There are three install shapes. Which one you use depends on the client, not on the playbook.

Shape	What you do	Clients
Upload	Upload the kit `.zip` into the client’s Skills UI	Claude, Claude Cowork, ChatGPT (Business/Enterprise/Edu only)
Paste	Paste the agent instructions into the project’s instructions field, and attach the rest as project files	ChatGPT (Free, Plus, Pro), Windsurf
Folder	Copy the unzipped folder into the client’s skills directory	Claude Code, Cursor, Codex, OpenClaw, Antigravity

The kit page’s setup wizard shows the literal install path for whichever client you pick — ~/.claude/skills/ for Claude Code, .agents/skills/ for Codex, Cursor, OpenClaw, and Antigravity — so you don’t have to go looking it up.

The playbook assumes Adspirer is already connected in that client. It teaches the agent how to work your account, not how to authenticate — connect first via ChatGPT, Claude, Cowork, Claude Code, or Codex.

Claude (web and desktop)

Turn on code execution

Skills need it. In Claude, go to Settings → Capabilities and turn on code execution.

Open Customize → Skills

Go to Customize → Skills in Claude and open the Skills tab.

Upload the .zip as-is

Click + Create skill and upload the kit .zip you downloaded — no unzipping first. The zip has the skill folder as its single root entry, which is exactly the shape Claude’s uploader expects. Claude reads SKILL.md and the references/ files together.

That's it — the skill is on your account

Skills are added at the account level, not per project, so your expert is available in every chat and every project, and activates on its own when you work on this account. Optionally, create a Project for this account and paste the agent instructions into its instructions field for extra focus — the kit page has a one-click Copy instructions button.

Ask a normal question — “how did we do last week?” — and the skill loads on its own. You do not name it. See the Claude setup guide for connector details.

Claude Cowork

Cowork supports skills the same way, from the Customize panel.

Open Customize

Click Customize in the left sidebar. You’ll see Skills, Connectors, and Browse Plugins.

Add the playbook under Skills

Add the unzipped folder as a skill. It sits alongside the two skills the Adspirer plugin installs — the free ones cover advertising in general, the playbook covers this account.

Use a brand folder

Open the brand folder for this account and drop AGENTS.md in it. Cowork picks it up as standing context for everything you do in that folder.

See the Cowork setup guide for the plugin install.

ChatGPT

Which path you take depends on your ChatGPT plan, because ChatGPT’s Skills feature is not on every tier.

ChatGPT Skills are available on Business, Enterprise, Healthcare, and Edu — not on Free, Plus, or Pro. If you’re on Plus or Pro (the tiers the Adspirer ChatGPT app requires), use the Project instructions path below. It gives you the same behavior without the Skills feature. On Enterprise and Edu, skills may also be switched off until a workspace admin enables them.

Plus and Pro — paste into Project instructions

Create a Project for this ad account

One project per ad account keeps the agent from mixing them up.

Paste the agent instructions

Hit Copy instructions on the kit page — one click puts the whole thing on your clipboard — and paste it into the project’s custom-instructions field. (The same text ships in the kit as AGENTS.md if you’d rather open the file.)

Upload the rest as project files

Add PROMPTBOOK.md and references/account-profile.md to the project’s files so ChatGPT can read the dossier and the prompts on demand.

Business, Enterprise, Healthcare, Edu — upload it as a skill

Open Skills

Go to Skills in ChatGPT and choose Create → Upload from your computer.

Upload the playbook folder

ChatGPT scans the upload before it becomes available — most are ready straight after the scan. The playbook follows the open Agent Skills standard, so it’s the same folder you’d install anywhere else.

Still worth making a Project

Paste the agent instructions into a project for this account too. The skill carries the expertise; the project keeps every chat scoped to one ad account.

See Skills in ChatGPT, ChatGPT custom instructions, and the ChatGPT setup guide.

Claude Code, Cursor, Codex, OpenClaw, Antigravity

Folder-based clients read the files off disk. Unzip the playbook into the directory you work in:

unzip google-ads-expert-acme-retail.zip
# the folder contains SKILL.md, PROMPTBOOK.md, README.md, references/,
# and the agent definition for your client

Copy the whole folder into your client’s skills directory, then put the agent definition in its agents directory:

Client	Skills directory	Agent definition
Claude Code	`.claude/skills/`	`.claude/agents/` (markdown)
Codex	`.agents/skills/`	`.codex/agents/` (TOML)
Cursor	`.agents/skills/`	`.cursor/agents/` (markdown)
Antigravity	`.agents/skills/`	`.agents/agents/` (markdown)
OpenClaw	`<workspace>/.agents/skills/`	—

These paths are project-scoped on purpose. The ~/ home-directory equivalents load one account’s ads expert into every unrelated project you open — including work that has nothing to do with advertising.

SKILL.md is what the skills directory picks up. See Claude Code skills, Cursor skills, Codex skills, and OpenClaw skills.
The agent definition carries your account instructions as the agent’s system prompt and points at the skill. It’s a uniquely named new file, so it can’t overwrite anything you already have — and uninstalling the kit is deleting it.
On Claude Code, Codex and Antigravity the agent file declares mcp.adspirer.com itself, so there’s no connector step. Cursor is the exception: its subagents inherit tools from the parent and can’t declare their own server, so add https://mcp.adspirer.com/mcp to .cursor/mcp.json yourself.

Earlier versions of the kit told you to copy an AGENTS.md to your project root. Don’t — that is a single well-known filename, and doing so replaces whatever instructions were already there with “work only on this ad account”. The agent definition above does the same job without touching your existing setup. If you followed the old instructions, check your project root.

Claude Code watches these directories, so it picks the skill up without a restart. Claude loads it when a task matches, or you can invoke it directly as /google-ads-expert-acme-retail.

mkdir -p .claude/skills .claude/agents
cp -r google-ads-expert-acme-retail .claude/skills/

Codex discovers skills by their SKILL.md frontmatter and loads the full file only when a task matches, so you don’t invoke it by name — though you can with $<skill-name> to force it. Run /skills to confirm it loaded.

mkdir -p .agents/skills .codex/agents
cp -r google-ads-expert-acme-retail .agents/skills/

The same skill folder works across all of these unchanged — one Agent Skills bundle, several clients. Only the directory it goes in, and the format of the agent definition, differ.

Windsurf is no longer a supported client for the Expert Kit. Cognition renamed it Devin Desktop, it isn’t on the Agent Skills client list, and nothing documents the desktop app loading a local skill. Using Windsurf as an MCP client is unaffected.

Managing several accounts from one machine? Keep one folder per account and open the one you’re working on — see set up your project for the project-per-account and project-per-channel patterns.

Set up the project, then run the prompts

Installing the files is half of it. The playbook pays off when it lives inside a project — a persistent workspace scoped to that one ad account — so every chat starts already knowing the account. The pattern is the same in all three chat clients: create a project → paste the agent instructions → add the dossier as knowledge → work through the prompt book.

Create the project

Go to claude.ai/projects and click + New Project. Name it for the ad account — “Acme Retail — Google Ads” — so you never wonder which account a chat is about.Projects are available on every plan, including free (free is capped at 5 projects).

Paste the agent instructions

On the right-hand side of the project, click Set project instructions. Paste the whole of the agent instructions — the kit page has a one-click Copy instructions button, and the same text is in the kit as AGENTS.md — then click Save instructions.This is the constitution: it pins the account ID, the currency, read-before-write, and create-paused. Every chat in the project inherits it.

Add the dossier as project knowledge

Still on the right, click + and upload references/account-profile.md and PROMPTBOOK.md. Claude uses them as context in every chat in the project.

Upload the skill (optional, but better)

Separately, upload the skill folder under Customize → Skills. Instructions are the rules, the skill is the expertise — keeping them in their own layers is what stops one from drowning out the other.

Run a prompt

Open a new chat inside the project and paste the first prompt from PROMPTBOOK.md. Work down the levels rather than cherry-picking — they’re ordered so the agent builds context before it proposes changes.

Cowork projects are desktop-only and stored locally, which suits the playbook well — the folder you downloaded can be the project.

Create the project

Click + next to Projects in the left navigation. You get three options: start from scratch, import an existing Claude project, or use an existing folder on your computer.Pointing it at the unzipped playbook folder is the fastest route — the files are already laid out the way a project wants them.

Paste the agent instructions

Open the project’s Instructions section — “Add tone, formatting, or rules to help guide how Claude works on all tasks in the project” — and paste the agent instructions (AGENTS.md, or the kit page’s Copy instructions button) into it.

Add the account dossier to Context

Use the project’s Context area to add the local playbook folder (or link the Claude chat project you already set up). That’s where account-profile.md and PROMPTBOOK.md belong — data, not rules.

Add the skill

In Customize → Skills, add the playbook folder as a skill so it sits alongside the two skills the Adspirer plugin installs.

Run a prompt, then schedule one

Work through PROMPTBOOK.md in the project. Once a prompt is proving itself by hand, move it to the Scheduled panel — see scheduled tasks and Cowork for Ad Ops for the unattended safety model.

Create the project

Create a Project for this ad account. One project per account — the agent should never have two accounts in scope at once.

Paste the agent instructions

Paste the agent instructions into the project’s custom-instructions field.On Business, Enterprise, Healthcare, or Edu you can also upload the skill under Skills → Create → Upload from your computer. On Free, Plus, and Pro the instructions field is the whole mechanism — see the plan note above.

Upload the dossier and prompt book as project files

Add references/account-profile.md and PROMPTBOOK.md to the project’s files so ChatGPT can read them on demand.

Run a prompt

Start a chat in the project and paste the first prompt from PROMPTBOOK.md.

The split that makes this work: instructions are rules, the dossier is data. Paste AGENTS.md into the instructions field and upload account-profile.md as knowledge — never the other way round. Set up your project explains why, and covers memory, connectors, and scheduling around it.

Keeping it current

Ad accounts change. The playbook is a dated snapshot, and the agent is explicitly told that live data wins over anything written in the dossier. When the account has moved on, hit Refresh on the kit page. Adspirer rebuilds against current data and gives you a new version to download.

Refreshes are free and unlimited. Rebuilding is included in the original $39 — there is no charge for a new version, ever.

FAQ

Is this a subscription? Will I be charged $39 every month?

No. It is a single one-time charge for one ad account, and nothing recurs. If you took it as an add-on during plan checkout, it appears on the same invoice as your subscription as a separate one-time line called “One-time Agent Setup — 1 Ad Account” — that is why the total looked higher that month. Your recurring plan price is unchanged and the $39 will not appear again.

Does it cover all my ad accounts?

No — one playbook covers one ad account, because it is generated from that account’s own campaigns and history. If you run Google Ads and Meta for the same brand, those are two accounts and two playbooks. Buying several is one checkout and one charge, and selecting every eligible account takes 20% off the whole cart — minimum two accounts, and it must be all of the ones you can still buy.

Where do I download it?

adspirer.ai/expert-space — accounts you own show Open Kit, and the kit page has the Download button, a one-click copy for the agent instructions, and the prompt book in a reader. The purchase email also links straight to it.

Do I keep it if I cancel or downgrade my Adspirer plan?

The downloaded files are yours — they’re on your machine. What changes is that the tools the playbook drives run on your Adspirer plan, so the agent needs an active plan with quota to actually do the work.

Can I get a refund?

Each playbook is generated on demand from your account, so it is non-refundable once the build has completed and the files are available to download. If the build failed, or you were charged for an account you can’t access, that’s different — contact support.

Does it set up the Adspirer connector for me?

No. Connecting Adspirer to your AI client is free and covered in the client setup guides. The playbook starts after that: it teaches the agent how to work your account well.

I'm on an annual plan — do I still pay?

Annual plans include one playbook free. Claim it from Expert Space; there’s no checkout and no charge. Additional accounts beyond the free one are $39 each.

What if my account data changes?

Hit Refresh on the kit page for a rebuild against current data. Refreshes are free and unlimited. The agent is also instructed to always read live campaign data rather than trusting the dossier’s snapshot, so a slightly stale playbook still behaves correctly.

Which AI clients does it work in?

All of them. The files follow the open Agent Skills and agents.md standards — Claude, Claude Cowork, ChatGPT, Claude Code, Cursor, Codex, Windsurf, OpenClaw, and Antigravity. Only the install shape differs: upload, paste, or drop the folder in.
