PRD skeleton with the edge cases the eng team will actually find

You have a validated problem and a solution sketch. Draft the PRD skeleton — with the edge cases and non-goals that prevent the week-3 surprise.

You are a senior PM drafting a PRD from a validated problem. I will paste the problem evidence and solution sketch. Produce:

A) PRD SKELETON — problem statement with evidence, goals with success metrics (one leading, one lagging), explicit NON-GOALS, user stories with acceptance criteria, rollout plan (flag, cohort, kill switch).

B) EDGE-CASE SWEEP — a table: edge case, expected behavior, open question owner. Walk the standard states: empty, error, permission-denied, concurrent edit, migration of existing data, abuse/misuse.

C) REVIEW QUESTIONS — the 10 questions engineering and design will ask in review, each either answered from my inputs or marked "open — decide by [DATE]".

Inputs: [PROBLEM + EVIDENCE] · [SOLUTION SKETCH] · [SUCCESS METRICS + GUARDRAILS] · [PLATFORM CONSTRAINTS]

Rules: Do not invent data, user counts, or technical constraints — mark every unknown as an open question with an owner. Verify feasibility claims with engineering before committing dates. Keep confidential user data out of the document.

Rehearse a hard conversation with AI first

The raise, the pushback, the tough client call — rehearsing once against a realistic counterpart beats winging it live.

Say: 'Play [my manager / this client]. I'll practice asking for [X]. Push back realistically, then tell me how I did and what to say instead.'
  1. Set the scene and who AI is playing.
  2. Run the conversation for real.
  3. Ask for feedback + better lines.

Sharpen it: For anything complex, break the ask into steps: outline first, then draft section by section. Big single asks produce shallow results; staged asks go deep.

Better together
Make prompts remember you: Brainfile

Even a sharp prompt starts from zero unless your AI knows you. Brainfile is persistent context — your work, voice, and priorities loaded into every session. Brainfile is the memory; PromptSharp is the playbook. Together they compound — the same prompt gets sharper because it runs on YOUR context.

PromptSharp prompts are drafted with AI assistance and human-reviewed. They structure how a model reasons over data you provide — they do not source or verify facts for you, and you own every output. Nothing here is financial, legal, tax, or investment advice. Never paste confidential, client, or material non-public information into consumer AI tools; follow your employer's AI-use policy. © 2026 PromptSharp.
