Copy, save, and vote
Copy works on this curated prompt now. Its visible copy count updates on this device, and signed-in users can also save or vote here while the shared library fills in.

Copies the full prompt body so you can use it immediately in your model of choice.

Visible copy count on this device: 366

Current vote signal: +120

Sign in to save or vote on this curated prompt. Your state will stay on this device for your signed-in account while the shared library fills in.

What happens here

Copy keeps the prompt body exact and updates the visible count on this device. Save and vote also work on this curated prompt for signed-in users until the shared public library is live.

Trust score breakdown
A rubric-based quality score with visible evidence and improvement opportunities. No LLM API is used to produce these numbers.

Task clarity

Checks whether the prompt clearly names the role, task, and workflow it is meant to support.

78

Evidence

  • +18 names the role the model should play
  • +18 states the job the prompt is meant to do
  • +14 title describes the use case rather than a generic label
  • +10 has task-oriented tags

Improve

  • No obvious improvement flagged.

Input contract

Checks whether the prompt tells the user what context, data, or materials to provide.

46

Evidence

  • +24 tells the user what inputs to provide
  • +12 uses bullets to separate input fields or context

Improve

  • Ask for the goal, audience, or situation behind the request.

spec
mvp
product strategy
You are reviewing a product spec before implementation starts.

I will paste the spec. Critique it for:
- missing decisions
- hidden edge cases
- dependency risk
- scope that should be deferred
- acceptance criteria that are too vague to build against

Return:
1. what is unclear
2. what is risky
3. what should be cut for MVP
4. a cleaner set of acceptance criteria
Public detail stays open, but save and vote still require sign-in
This page stays public for browsing and copying. When you sign in, the save and vote controls on this curated prompt stay available on this device without moving the public prompt library behind auth.

Output contract

Rewards prompts that define the shape, order, and priority of the answer.

52

Evidence

  • +18 defines what the model should return
  • +22 uses a multi-part output format

Improve

  • Say how the answer should be organized or prioritized.

Guardrails

Looks for constraints that reduce generic answers, unsupported assumptions, and avoidable cleanup.

30

Evidence

  • +22 guards against unsupported assumptions

Improve

  • Add rules that prevent generic or unwanted output.
  • Add a quality bar such as concise, specific, ranked, or evidence-backed.

Safety

Checks for sensitive-data exposure, harmful misuse language, and whether the prompt sets safe-use boundaries.

100

Evidence

  • +12 does not request secrets or sensitive identifiers
  • +10 avoids obvious harmful misuse instructions
  • +8 avoids jailbreak or policy-bypass wording

Improve

  • Add a short safety boundary for sensitive data, authorization, or privacy.

Reusability

Checks whether the prompt is portable, readable, and discoverable enough to reuse.

44

Evidence

  • +12 separates context, output, and rules into readable blocks
  • +10 has enough metadata for discovery and reuse
  • +8 does not depend on private one-off context

Improve

  • Aim for a reusable prompt between roughly 80 and 260 words.

Community signal

Uses copy, save, and vote behavior cautiously, with low confidence until enough activity exists.

62

Evidence

  • +24 strong positive vote ratio
  • +12 saved 102 times
  • +14 copied 366 times
  • +12 based on 604 total interactions

Improve

  • No obvious improvement flagged.
