The PO Prompt Vault
A prompt library and spec-template system for product work. Every prompt is documented like an engineering artifact: when to use it, what to paste in, a worked example, and where it fails. Drawn from a production AI-assisted pipeline, not a "500 magic prompts" pack.
- 60+ documented prompts across 7 categories, from PRDs to API contracts.
- One required paste per prompt — everything else is optional, with explicit fallbacks.
- Worked examples and documented failure modes on every single prompt.
What's inside
Seven categories. One standard.
Prompt packs give you prompts. The Vault gives you a system that knows your platform: a paste-once Context Card, prompts that infer what you didn't provide and tag it [INFERRED — confirm] instead of inventing silently, and outputs formatted to chain into the next prompt.
Two honesty notes, because the Vault's premise is that nothing is invented invisibly: the API & contracts category carries full worked examples — the other six carry compact input→output excerpts. And every example is an authored target showing what good output looks like, not a captured chat transcript.
Don't take the standard on faith — read one complete prompt, ungated : when to use, what to paste, the worked example, and where it fails.
01. PRD & framing
From discovery mess to a document that survives review — framing, evidence audits, scope cuts, the hostile-review pass.
02. User stories & AC
Vertical slices, testable Thens, the negative scenarios everyone forgets, and the pre-refinement rituals that save the meeting.
03. API & contract design
The deep category — breaking-change analysis, error envelopes, idempotency, authorization matrices. Full worked examples on every prompt.
04. Backlog hygiene & refinement
The Thursday toolkit: batch readiness sweeps, risk-first agendas, sprint goals you can actually fail, spillover post-mortems.
05. Stakeholder comms & decisions
Decision memos with deadlines, bad news with the lede unburied, escalations that survive being forwarded, status that replaces the meeting.
06. Discovery & inputs
Interview guides built to kill assumptions, synthesis with receipts, support-ticket mining, precise data-pull requests.
07. Spec→dev pipeline
Working with AI inside delivery: context packs, implementation briefs, spec linting, acceptance review of generated code, guardrail checklists.
