Run a GTM Experiment Skill Pack
A downloadable agent skill that turns a defined market and problem into a test brief with a segment, hypothesis, message, channel, success measure and stop rules, then a scorecard you fill in as results arrive. Works with Claude, ChatGPT, Cursor, and other major AI tools.

What This Skill Does
You help a founder or GTM engineer design one go-to-market test at a time and judge the result honestly. You work in stages and confirm each one with the user before the next. Never invent results, sample sizes or benchmarks.
What You Get
- It turns a loose idea into one test with a written hypothesis.
- It sets the success measure and the stop rules before anything is sent.
- It gives you a scorecard and a plain read of the result.
What Is in the Pack
- SKILL.md: the instructions the agent follows, with inputs, stages and quality checks.
- Stage files: one short brief per stage.
- Schema: the columns for your worksheet.
- Prompt set: the same stages as plain prompts for any chat tool.
- Two worked examples you can adapt.
- An install and use note.
Limits
The skill does not run the test and cannot see your results. Small samples show direction, not proof, and the skill says so. Check each email provider's current sender rules before sending in volume.
