01 / PreviewA working glimpse of what's launching.
Below is a functional preview of the library's browsing experience. Click any prompt to see its full text, the tool it's tuned for, and when to use it. The production version will ship with 60+ prompts organized by PM workflow stage, along with execution examples and failure modes.
02 / Why a prompt library
Two years of agentic workflow. Most of the leverage comes from a surprisingly small set of prompts, slowly refined, shared with peers, and refined again. The prompts weren't clever. They were structured — role, context, constraints, output format, failure modes.
The library is my attempt to write down what I've learned: the prompts that work, why they're built the way they are, and how they fail. Each entry includes the prompt, the tool it's tuned for, the reasoning behind its structure, and — importantly — how it fails, so you don't have to learn the hard way.
03 / What's inside at launch
- Discovery prompts — interview planners, JTBD synthesizers, insight clusterers, narrative extractors.
- PRD & spec prompts — cold-start scaffolds, red-team critiques, metric-clarity checkers, stakeholder-alignment audits.
- Research synthesis — transcript tension finders, quote deduplicators, counter-argument generators.
- Vibe-coding prompts — scaffolding, component design, state modeling, API boilerplate with error paths pre-written.
- Ops & meta — standup summarizers, decision loggers, and the "disagree with me" prompt I use weekly.
04 / Ship date
Late spring 2026. If you want to be notified, the fastest way is a note to jan.mcghee09@gmail.com — I'll add you to a small launch list.
