Set up the Adspirer "The Channel Mix Advisor" skill for me. If you can run commands: npx adspirer-skills add the-channel-mix-advisor If not: fetch https://www.adspirer.com/skills/the-channel-mix-advisor.md and follow it. Then read the skill and ask me what you need to get started.
Paste it into Claude, ChatGPT, Cursor, Codex, Gemini, or any agent — it works out how to install itself.
Or install it yourself
npx adspirer-skills add the-channel-mix-advisor Writes SKILL.md to .claude/skills/ in the current project. The bundled references, scripts, and assets ship with the ZIP. Download ZIP →
Upload the ZIP in Claude → Settings → Skills. The bundle preserves every reference, script, and asset.
Install the Adspirer plugin first: Cowork tab → Customize (left sidebar) → Plugins → Browse Plugins → search "Adspirer" → Install. Requires Claude Max, Team, or Enterprise. Then upload this ZIP as a skill.
In ChatGPT, open Plugins → Skills → Create → Upload from your computer. ChatGPT scans the skill before making it available. Availability and upload permissions depend on your workspace plan and admin settings.
npx adspirer-skills add the-channel-mix-advisor --agent cursor Writes the skill to .cursor/rules/ in the current workspace, so Cursor loads it on every session.
npx adspirer-skills add the-channel-mix-advisor --agent codex Appends the skill to AGENTS.md, which Codex reads on every session — so it persists instead of living in one conversation. The append is idempotent; re-running it will not duplicate the block.
npx adspirer-skills add the-channel-mix-advisor --agent gemini Appends the skill to .gemini/GEMINI.md, which the Gemini CLI reads on every session. Connect Adspirer as an MCP server first so the live ad-account steps can run.
npx adspirer-skills add the-channel-mix-advisor --agent windsurf Writes the skill to .windsurf/rules/ in the current workspace, so Windsurf loads it on every session.
npx adspirer-skills add the-channel-mix-advisor --agent other Writes SKILL.md to adspirer-skills/ in the current folder — point any agent at that file. No shell? Fetch the raw file with curl -fsSL https://www.adspirer.com/skills/the-channel-mix-advisor.md, which prints the skill instead of installing it.
Starter prompt
Client setup guide →Use The Channel Mix Advisor skill. I’m working on [campaign or account] and want to understand [goal or problem] for [date range]. Check that Adspirer is connected, start by looking without changing anything, and explain the story in plain language. Show me the evidence and ask before making any live change.Where it helps
When to use the media mix skill
A split you can defend line by line, with platforms ruled out for stated reasons and cold channels carrying an explicit learning allowance.
Use case 1
A budget needs splitting for the first time
A launch or new quarter needs an allocation someone can justify in a review.
Use case 2
A platform is being added on instinct
The team needs to know whether the audience and geography actually support it.
Use case 3
The budget may be spread too thin
Splitting across too many channels can guarantee that none of them produces a usable read.

Media mix examples
The numbers, account, and recommendation will be yours. These show the kind of story the skill helps you work through.
Ruling a channel out
A B2B client wants to add a platform where its buying audience is barely reachable.
The skill excludes it with the reason stated, which settles the argument better than opinion.
Cold channel allowance
One recommended platform has no conversion history in the account.
The skill allocates a test budget and labels it a hypothesis rather than presenting a forecast.

Agent skills related to media mix
The Media Plan Builder
From a brief (product, audience, budget, goal, market), produce a defensible media plan: audience definitions, budget split across channels, flighting calendar, and a channel-mix rationale. Cross-platform. Uses Similarweb/Semrush for competitive context if connected. Plan doc, not a live launch.
Audience Architect
Build a cold-to-hot audience structure sized to the account's real event volume, with overlap and exclusions handled deliberately.
The Budget Reallocator
Find capped winners and weak spenders across a campaign set, and propose moves sized to avoid resetting learning.
Before you install
Frequently asked questions
What is the media mix skill?
It is an Agent Skill — a folder of instructions your AI assistant loads when you ask it to do this job. It follows the open Agent Skills specification, so the same package works across different assistants. Recommend a channel split justified by each platform's mechanics for the stated objective, with honest reasoning and named uncertainty. Unlike a prompt you paste in, the skill carries its own procedure, checks, and stop conditions, so the assistant works the same way every time you run it.
Which AI assistants can run it?
Claude, Claude Code, Claude Cowork, ChatGPT, Codex, Cursor, Gemini and Windsurf. Download the ZIP and upload it in assistants that accept skill folders, or point the assistant at the raw SKILL.md file. The install card above has the exact step for each one.
What do I need to connect before I run it?
Adspirer is required, because the skill reads live account data rather than guessing. The skill confirms the connection before it touches a real account, and tells you plainly if something is missing.
Do I need an Adspirer account, and is there a free tier?
The skill itself is free to download and MIT-licensed. To let it read or change real ad accounts you need Adspirer connected: the free tier includes 15 tool calls a month, Plus is $49/mo for 150, Pro is $99/mo for 600, and Max is $199/mo for 3,000. You can install the skill and read what it does before signing up for anything.
Can it change my campaigns without asking?
No. Any new campaign Adspirer creates is created paused, enabling a paused or live campaign needs your confirmation, and destructive actions are gated behind an explicit confirmation flag. Spend, publishing, and live changes wait for your approval every time — installing a skill or a connector is not itself approval to act.
How do I get the best results from it?
Give it the specifics it asks for up front — the account or campaign, the date range, the goal, and what "good" looks like for this business. Let the first pass run read-only so you can check the evidence before anything changes. The starter prompt above is a working template; edit the bracketed parts and paste it in.
How is this different from just asking the assistant directly?
A plain prompt gets you a plausible answer from whatever the model already knows. This skill makes the assistant pull real numbers from your ad accounts, follow a fixed procedure, show its evidence, and stop at the points where a person should decide. That is the difference between a confident guess and a media mix you can act on.
