About brainstorm-experiments-existing
brainstorm-experiments-existing
Design experiments to test assumptions for an existing product
brainstorm-experiments-existing is an agent skill for designing low-effort experiments that test the assumptions behind a feature idea for a product that already exists. Instead of building the full feature, the team validates the riskiest assumptions first using methods such as prototypes, A/B tests, technical spikes and other cheap validation approaches. You describe the idea and the assumptions, and the skill first clarifies what the team wants to build and what it needs to learn. If you provide PRDs, assumption lists or design files, the skill reads them before proposing anything. It then works through the experiment design step by step, so each proposed test names what it will show and what result would change the decision. It is used by product teams that want to avoid committing engineering time to a feature before they know it will work. The skill is part of the pm-skills collection by phuryn and is listed on skills.sh as free.
