Design experiments to test assumptions for an existing product — prototypes, A/B tests, spikes, and other low-effort validation methods. Use when validating assumptions, testing feature ideas cheaply, or planning product experiments.

Install

With your agent

Install OMGSkills skill "phuryn/pm-skills:brainstorm-experiments-existing" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.

Manual command

git clone https://github.com/phuryn/pm-skills /tmp/pm-skills && ln -s /tmp/pm-skills/pm-product-discovery/skills/brainstorm-experiments-existing ~/.claude/skills/brainstorm-experiments-existing

From README

Design Experiments (Existing Product) Design low-effort experiments to test product assumptions before committing to full implementation. Context You are helping a product team design experiments for $ARGUMENTS. The team has a feature idea and assumptions that need validation. If the user provides files (PRDs, assumption lists, designs), read them first. Instructions The user will describe their idea and assumptions. Work through these steps: Clarify the idea and assumptions: Confirm what the team wants to build and what they need to validate. Suggest experiments for each assumption.
