Prompt Gallery¶
Learn how to write effective prompts by studying real examples from the sample library. Three fictional companies demonstrate three different prompting styles — all produce equally thorough outputs.
The Three Styles¶
| Style | Company | Who it's for |
|---|---|---|
| Organized | Storevine (B2B) | PMs who prepare structured notes and reference prior artifacts |
| Casual | Brainshelf (Consumer) | Lean teams moving fast — bullet points, shorthand, enough context to work |
| Enterprise | Workbench (Enterprise) | High-documentation environments with stakeholder scrutiny |
PRD Prompts¶
Organized (Storevine)¶
/prd
Feature: Campaigns — native email marketing for Storevine merchants
Context: Storevine all-in-one ecommerce + web builder, ~18k active merchants
[fictional]. See: competitive-analysis (filed last week), problem-statement
(approved), solution brief (approved), spike summary (SendGrid selected),
ADR (SendGrid for dedicated IP warm-up).
Scope for v1:
- Template-based email campaigns (no drag-and-drop builder)
- Audience segmentation by purchase history and tags
- CAN-SPAM and GDPR compliance built in
- Scheduled sends with merchant timezone support
Casual (Brainshelf)¶
/prd
resurface prd for sprint 8. pulling everything together: solution brief,
adr (resend), design rationale (text layout), spike (tfidf).
building the daily email digest that surfaces 3-5 saved items matched
to reading patterns. 85k registered, 22k MAU [fictional].
Enterprise (Workbench)¶
/prd
Here is the structured brief for the Blueprints v1 PRD.
**Product context:**
- Workbench collaboration platform, ~500 enterprise customers [fictional], Series B
- Competitors: Confluence (Atlassian), Notion, Coda, Monday.com
- Key stakeholders: VP Engineering, Head of Legal, IT Security Lead,
3 department heads (Engineering, Ops, Marketing)
**Problem:** 60% of enterprise projects lack an approved kickoff doc at
handoff [fictional]. Teams use ad-hoc templates that miss required sections.
**Solution:** Blueprints — reusable document templates with required sections
and role-based approval gates.
Hypothesis Prompts¶
Organized (Storevine)¶
/hypothesis
Project: Campaigns — native email marketing for Storevine merchants
Stage: Post-discovery, pre-PRD finalization
Hypothesis I want to define:
- Non-adopter merchants (no active external email tool, <250 customers)
are ~38% of our active base [fictional]
- If we offer pre-populated templates and a 3-step "send your first campaign"
wizard, we can increase first-send rate from 12% to 30% [fictional]
Casual (Brainshelf)¶
/hypothesis
trying to figure out if a morning digest email will actually get people to
re-read their saved stuff. context: brainshelf pkm app, 22k MAU [fictional].
users save ~47 items/month but revisit fewer than 9% within 30 days.
Enterprise (Workbench)¶
/hypothesis
Blueprints required-section feature. We believe that enforcing required
sections in document templates will reduce time-to-approved-doc from
4 days average to 1 day [fictional] for enterprise teams.
Validation approach: A/B test, required vs. optional sections, 50/50
split across new Blueprint creations for 4 weeks.
Competitive Analysis Prompts¶
Organized (Storevine)¶
/competitive-analysis
Scope: Email marketing tools available to ecommerce merchants — built-in
vs. third-party positioning. Informing Campaigns v1 scope and feature
prioritization.
Our product: Storevine — B2B all-in-one ecommerce + web platform, Series A,
~18k active merchants [fictional].
Competitors to evaluate: Shopify Email, Squarespace Email Campaigns,
Wix Ascend, Klaviyo, Mailchimp, Drip
Casual (Brainshelf)¶
/competitive-analysis
read-later / pkm space, focusing on who does resurfacing or spaced
repetition. readwise is the main one. also raindrop, omnivore,
instapaper, pocket. we're brainshelf, 22k MAU consumer pkm app.
Experiment Design Prompts¶
Organized (Storevine)¶
/experiment-design
Project: Campaigns guided first-campaign flow
Experiment: Does the guided flow increase first-send rate for non-adopter
merchants?
Hypothesis: Pre-populated templates for non-adopter merchants (<250
customers, no external email tool) will drive first-send rate from
12% to 30% within 14 days of account creation [fictional].
Key Takeaway¶
All three prompt styles produce equally thorough, complete artifacts. The difference is in how much context you provide up front:
- Organized: References prior work, provides structured context, names specific numbers. Less back-and-forth with the skill.
- Casual: Gives enough context to produce a good artifact but skips polish. The skill fills in structure and completeness.
- Enterprise: Full stakeholder lists, quantified baselines, explicit metric definitions. Every artifact can withstand scrutiny.
The best prompt is the one you'll actually write. If you're moving fast, a Brainshelf-style prompt works. If you're presenting to the board, a Workbench-style prompt gives you more control over the output.
