Product work is mostly judgment under uncertainty, and chat models are best used as sparring partners: they widen options, find gaps in your thinking and do the formatting grind. These prompts are written that way - each one forces the model to state assumptions, separate evidence from guesses and say what would change the answer.

You get 31 prompts in five groups: discovery and research, strategy and roadmap, specs and delivery, growth and metrics, and fundraising and operations. Interview guides, opportunity scoring, PRDs, experiment design, pricing tests, investor updates and more. Every prompt ships with variables, usage notes and an example of the output shape.

All content is CC0 plain markdown plus an offline browser to search, fill variables once and copy. Use it with any assistant, in a Claude Project, or in your team wiki.
