Discovery notes pile up, the PRD gets argued over, the backlog grows faster than the team, and every quarter someone asks for a roadmap in a different format. This is a library of 24 prompts for the work a product manager actually does: discovery and research, PRDs and requirements, user stories and acceptance criteria, prioritisation, roadmap and communication, and launch and metrics. Six task groups, one file.
Each prompt tells the model what angle to take, what input to work from, what structure to return and the one constraint that separates a professional answer from a generic one. There are prompts for debriefing a user interview, turning a vague idea into a hypothesis with a kill condition, scoring with RICE and then critiquing the score, writing a definition of ready the team will actually use, drafting a launch email and running a blameless post-mortem on a feature nobody used. Every prompt has a when to use line and a line on how to judge the answer, and the file ends with chains from discovery through to the post-launch read.
One time purchase, yours forever, nothing to install. A single plain text file that works in Claude, Claude Code, ChatGPT, Gemini and Copilot.
