app-marketplace-launch-marketing makes Claude act as a marketplace-marketing advisor for the operator side. It drafts a program document in six steps: gate the launch moment, size the founding cohort, plan the reveal, design the featuring and spotlight program, split the budget, and define measurement.

It loads when you mention launching an app marketplace, picking launch partners, featured apps, MDF or a joint announcement. It asks ten interview questions first and drafts section by section, checking each with you. It is operator side only and bundles three reference files and no scripts.

Good for

Platform teams launching a B2B SaaS app marketplace
Partner-marketing leads deciding who gets co-marketing budget
Teams running a featured-apps or app-of-the-month program

What's in the skill

When it loads

Design a B2B SaaS marketplace operator's launch and ongoing app co-marketing program - sizing and gating the founding launch cohort, the keynote-anchored reveal and partner embargoes, featured-placement and app-of-the-month spotlight governance, and the budget split between marketplace-wide demand generation and rationed per-partner co-marketing (MDF, paid catalogs, tier gates). Use whenever the user mentions launching an app marketplace, picking launch partners, featured apps, partner spotlights, MDF, or a joint launch announcement - even if they never say "marketplace launch". Operator side only. Do NOT use for a vendor optimizing its own listing elsewhere - use samber/developer-platform-skills@integration-listing-optimization instead.

What it includes

Asks ten questions, then drafts the program section by section.
If question 1 says the marketplace is already live, it skips step 2 and compresses step 3.
Try: “Partners keep asking for co-marketing and we're drowning - how do we decide who gets MDF without it looking like favoritism?”

Questions

How do I install app-marketplace-launch-marketing?

Use the install box at the top of this page. The README says to install every skill in samber/developer-platform-skills, not one, because the skills hand work to each other. Pick one route per agent.

Does app-marketplace-launch-marketing work in Claude, Codex and Cursor?

The README documents install routes for Claude.ai (plugin marketplace), Claude Code, Codex, Cursor, Gemini CLI and the skills.sh CLI. The install box lists each one.

What does it ask me before it designs anything?

SKILL.md lists ten questions to ask first, and the answers change the later steps. Have your current setup and constraints ready.

Does it run scripts or need an API key?

It bundles no scripts. The folder holds SKILL.md, reference Markdown files and an evals file, and the skill works by asking you questions and writing advice.

Is app-marketplace-launch-marketing safe to install?

It bundles no scripts, so installing it adds instructions and reference files rather than programs. SKILL.md also suggests that, if your agent keeps notes in a file, it uses developer-platform-context.md. Our advice: keep that file out of public commits if it holds company plans, and check any figures the skill cites against their sources before quoting them to customers.

Is this for vendors listing their own app?

No. SKILL.md says this skill is operator side only and points vendors optimizing their own listing to integration-listing-optimization.
