Corey Haines: product-marketing

A source-inspected Agent Skills file for a reusable product-marketing context document.

Reviewed 2026-10-08

When this is useful

Repeated AI tasks keep starting from inconsistent product assumptions

Prepare the inputs

Product capability, intended buyer, alternatives and evidence

This is an instruction file rather than a standalone application. The host needs to support the file format and any tools the task requires.

Expected artifact

A reusable product-marketing context document

Our original evaluation criterion: Unknowns must stay unknown; the context needs an owner and dates on important evidence.

Install and evaluate

The source file is `skills/product-marketing/SKILL.md` in `coreyhaines31/marketingskills`. Follow that repository's current installation instructions. The README documents installing a selected skill with `npx skills add coreyhaines31/marketingskills --skill product-marketing`. Product-marketing context is shared across several skills.

Put it to work

  1. Read the linked skill source and its referenced files.
  2. Prepare the stated inputs and use a fictional or sanitized case first.
  3. Unknowns must stay unknown; the context needs an owner and dates on important evidence; record what needs verification before using the output.

Limits and tradeoffs

The source was read but this skill was not installed or run. Model quality, tool access and permissions vary by host. Review third-party instructions and provide real product evidence before execution.
