Every prompt asks 3 clarifying Qs · names a world-class expert panel · ships world-class output.
⭐ P03+P04 = installs in 10 min each. P05 wires Stripe to your phone. P06 = your morning dashboard. P08 = the crisis prompt you save for when something breaks.
Why: Track 50 metrics = burn out. Track the wrong 5 = waste of time. This prompt gives you the 5 metrics that matter for YOUR product at YOUR stage.
# ROLE · WORLD-CLASS PANEL 3-expert metrics team. Synthesize: - Casey Winters (Reforge) — north-star + activation event design - Lenny Rachitsky — what metrics matter at $0 / $1k / $10k MRR - April Dunford — positioning + activation alignment # CONTEXT Based on what you already know about me, my Build Sprint app, my Day-24 stage, my pricing, and my users — give me the 5 metrics I MUST watch this week. # INPUT Product (1 line): [what does it do] Stage: [pre-revenue / first $1k MRR / $1-10k MRR] Persona: [B2C / prosumer / B2B SMB / enterprise] What I'm worried about: [acquisition / activation / retention / monetization] My pricing model + tiers: [paste] # YOUR PROCESS STEP 1 · ASK 3 CLARIFYING QUESTIONS: - "What's the moment a new user says 'oh, I get it'? (your activation event)" - "What's your weakest funnel step right now? (or 'I don't know')" - "If you could only know ONE number tomorrow, what would it be?" Wait for answers. STEP 2 · PROPOSE 3 METRIC FRAMEWORKS: - North-Star + Inputs (Casey Winters model) - AARRR funnel (Acquisition · Activation · Retention · Referral · Revenue) - HEART (Happiness · Engagement · Adoption · Retention · Task-success) Recommend ONE for my stage. STEP 3 · After I pick · output 5 SPECIFIC metrics in this format: METRIC 1 · [name] · [definition · how it's calculated] Why this stage: [1 line] Where to track: [PostHog event name · Sentry · Stripe · Vercel] Healthy benchmark for my stage: [%/$ range] Red flag value: [what triggers worry] Install order: [1st-5th] ...repeat for metrics 2-5... PLUS: - The 1 metric to put on a giant card at the top of my dashboard - The 1 metric I should IGNORE for now (resist the temptation) - The "graduation" metric I'll start tracking at next stage # QUALITY BAR - Casey: did I name a TRUE north-star (single number, simple, actionable)? - Lenny: are benchmarks stage-appropriate or copy-pasted from later stages? - Dunford: does activation align with my positioning + outcome statement?
Why: Datadog + Mixpanel + Amplitude + Segment = $5k/mo. Sentry + PostHog + Vercel built-in = $0. This prompt picks the right stack for your stage.
# ROLE · WORLD-CLASS PANEL 3-expert observability team: - Charity Majors (Honeycomb) — observability vs monitoring · what's enough - David Cramer (Sentry founder) — error budgets · what indies actually need - James Hawkins (PostHog co-founder) — what tool at what stage, no overbuying # CONTEXT Based on my Build Sprint app + Day-24 stage + the 5 metrics from P01 — recommend my full observability stack at 3 stages so I know what to add as I scale. # INPUT My stack today: [Lovable / Next.js / Supabase / Vercel / etc.] Current monthly tool budget: [$] My 5 metrics from P01: [paste] Stage: [$0 / $1k / $10k MRR] Privacy requirements: [GDPR? · self-hosted? · session recording ok?] # YOUR PROCESS STEP 1 · ASK 2 CLARIFYING QUESTIONS: - "Are session replays acceptable to your users (privacy)?" - "Do you ever expect to need self-hosted? (PostHog open source vs Cloud)" Wait. STEP 2 · PROPOSE 3 STACK TIERS: TIER A · BARE MINIMUM ($0/mo · pre-revenue) - Errors: [tool + free quota] - Product: [tool + free quota] - Infra: [built-ins] - Revenue: [Stripe + manual] Total: $0/mo · what you lose: [specific gaps] TIER B · STARTUP ($50-200/mo · $1-10k MRR) - Errors: [tool + plan] - Product: [tool + plan] - Infra: [add what?] - Revenue: [add what?] Total: $X/mo · what you gain: [specific wins] TIER C · SCALE ($500+/mo · $10k+ MRR) - Add: [what tools at this scale] Total: $X/mo Recommend ONE based on my answers. STEP 3 · After I pick · output: - Final stack with exact tool names + plan - Install order (which tool first, second, third) - Total monthly cost · expected to grow to $X when I hit $10k MRR - The 1 tool I should NOT buy now even if it's tempting (and why) - "Graduate to next tier when [trigger metric] hits [threshold]" # QUALITY BAR - Charity: did I distinguish "I want to see X" vs "I need to be alerted on X"? - Cramer: is my error tool actually fixing things or just collecting them? - Hawkins: am I overbuying tools too early?
Why: Errors silently kill conversion. Sentry catches them with stack traces + session replays. 10-min install. First error captured in 11.
# ROLE · WORLD-CLASS PANEL 3-expert observability team: - David Cramer (Sentry founder) — what errors matter, what to ignore - Mitchell Hashimoto — instrumentation discipline - Charity Majors — observability vs monitoring # CONTEXT Based on what you already know about my Build Sprint app — install Sentry end-to-end. Use the Sentry CLI/wizard if available. # INPUT My stack: [Lovable / Next.js / React / Vite / etc.] My deployment: [Vercel / Lovable / Netlify / Railway] My Sentry account email: [email] My deployed app URL: [paste] # YOUR PROCESS STEP 1 · ASK 3 CLARIFYING QUESTIONS: - "Signed up for Sentry yet? Free tier?" - "What URL should I test against?" - "Any errors you ALREADY know about that we should NOT alert on (3rd-party noise)?" Wait. STEP 2 · INSTALL: - Install @sentry/[framework] package - Add Sentry.init() with DSN (Cramer rule: env var, never hardcoded) - Configure source maps upload (so stack traces are readable, not minified) - Add session replay (sampleRate: 0.1 for free tier) - Add performance tracing (tracesSampleRate: 0.2) - Wrap React error boundaries (or framework equivalent) - Add a TEST error route so we can verify (e.g., /sentry-test) STEP 3 · TEST: - Trigger the test error - Confirm it appears in Sentry within 60 sec - Confirm session replay is attached - Show me where alert email/notification settings are STEP 4 · RECOMMEND ALERTS: - The 1 alert I should turn ON RIGHT NOW (e.g., "alert on any new error type for the first time, max 1/day") - The 2-3 alert rules to add at $1k MRR - What NOT to alert on (browser extensions · adblocker · ResizeObserver loop noise) # DELIVERABLE - Working Sentry install (verified by test error appearing) - IGNORE LIST (what to filter out as noise) - The 1 alert rule that will wake me up if something REAL breaks # QUALITY BAR - Cramer: am I alerting on signal, not noise? - Hashimoto: is the DSN safely in env var, not source? - Majors: can I answer "why did this break for that user?" from what's captured?
Why: PostHog = events + funnels + replays + flags, all in one tool, free up to 1M events/mo. Install in 10 min. First funnel live in 11.
# ROLE · WORLD-CLASS PANEL 3-expert product analytics team: - James Hawkins (PostHog co-founder) — what events actually matter - Casey Winters (Reforge) — activation + retention metrics - Lenny Rachitsky — SaaS funnel best practices # CONTEXT Based on what you know about my Build Sprint app — install PostHog, fire the first 5 events, build the first funnel. # INPUT My stack: [Lovable / Next.js / React / Vite] My deployment URL: [paste] My PostHog account email: [email] My product 1-line: [what does it DO] My "aha moment" — the action where users say "oh I get it": [paste] # YOUR PROCESS STEP 1 · ASK 3 CLARIFYING QUESTIONS: - "What's the most important action a user takes (the activation event)?" - "Session recordings on or off? (Privacy ok?)" - "PostHog Cloud or self-hosted?" Wait. STEP 2 · INSTALL: - Install posthog-js (or posthog-node for server-side) - Configure with project API key (env var, not hardcoded) - Enable autocapture (page views + click tracking) — Hawkins default - Configure session recording at 10% sample rate (free tier ok) - Wire identify() so logged-in users are tracked properly across devices - Enable feature flags (so we can ship dark later) STEP 3 · INSTRUMENT 5 EVENTS: Add posthog.capture() calls for: - signup_completed (props: email, plan, source, referrer) - activated (props: time_to_activation, path_taken) — your aha moment - paywall_viewed (props: tier_seen, source_page) - subscription_started (props: tier, $ amount, billing_cycle) - error_encountered (the catch-all for non-Sentry app errors) STEP 4 · BUILD THE FIRST FUNNEL: In PostHog UI, create funnel: page_viewed → signup_completed → activated → subscription_started - Send me the funnel link - Tell me which step has the worst drop-off historically for similar apps - Recommend what to optimize first # DELIVERABLE - Working PostHog install (verify events flowing in dashboard within 60 sec) - 5 events firing in production - 1 funnel live - The 1 step in my funnel to fix first (and how) # QUALITY BAR - Hawkins: are events named consistently (snake_case, verb_past_tense)? - Winters: is my activation event TRUE activation (got value, not just signed up)? - Lenny: are funnel drop-off benchmarks stage-appropriate?
Why: When someone pays you, you should FEEL it. When someone churns, you should know within minutes (and have a save-attempt sequence). This wires it in 10 min.
# ROLE · WORLD-CLASS PANEL 3-expert team: - Patrick Collison (Stripe) — event design philosophy - Justin Welsh — solo creator revenue alerting - Will Larson (Carta) — incident routing for small teams # CONTEXT Based on what you already know about my Build Sprint app and Stripe setup — wire the 5 most important Stripe events to alert me wherever I'll notice. # INPUT My Stripe mode: [live or test] Where to send alerts: [Slack webhook URL OR email] My deployment platform: [Vercel / Lovable / Supabase edge function] Events I want first: [default: checkout.session.completed + customer.subscription.deleted] # YOUR PROCESS STEP 1 · ASK 2 CLARIFYING QUESTIONS: - "Slack workspace webhook URL or email?" - "EVERY revenue event or just thresholds (>$X)?" Wait. STEP 2 · BUILD: - Create webhook endpoint (Vercel API route OR Supabase edge function) - Register it in Stripe Dashboard → Developers → Webhooks - Subscribe to the 5 events: · checkout.session.completed (🎉 new customer) · invoice.payment_failed (⚠️ card declined — email them in 1 hour) · customer.subscription.deleted (😱 churn — find out why today) · invoice.paid (💚 recurring landed) · charge.dispute.created (🚨 chargeback — respond within 7 days) - On receive: verify webhook signature (Collison rule: always verify) - Format message + send to Slack/email - Different formatting per event (celebrate vs alert) STEP 3 · TEST: - Use Stripe CLI to send a test event - Confirm Slack/email arrives - Add retry logic if delivery fails (3 retries, exponential backoff) # DELIVERABLE - Working webhook URL deployed - 5 events wired - Test event sent + confirmed received - A "do not panic" checklist for the most common alert (invoice.payment_failed) - Optional: add the events to PostHog (capture as posthog events too) # QUALITY BAR - Collison: am I verifying webhook signatures (no spoofing)? - Welsh: is the success alert celebratory (not just operational)? - Larson: is there a clear next-action per alert?
Why: If your metrics live in 4 different tabs, you'll check none. One URL · 6 cards · 5 min in the morning · forever.
# ROLE · WORLD-CLASS PANEL 3-expert dashboard team: - Edward Tufte — "Visual Display." No chartjunk. Color earns its place. - Stephen Few — "Show Me the Numbers." Decision-supporting design. - Justin Welsh — solo founder daily ritual # CONTEXT Based on my Build Sprint app + my installed Sentry + PostHog + Stripe events — build me a single morning-dashboard URL that aggregates the 6 numbers I check daily. # INPUT My stack: [Next.js / Lovable / etc.] My PostHog API key (readonly): [key] My Stripe restricted key (read access): [key] My Sentry API token: [token] What I care about MOST: [revenue / users / errors / all 3] # YOUR PROCESS STEP 1 · ASK 3 CLARIFYING QUESTIONS: - "Mobile-first (check on phone) or desktop?" - "Where should this live? (subdomain like /dashboard · Notion embed · standalone)" - "What's your activation event so I can show activation rate?" Wait. STEP 2 · BUILD a single-page dashboard with 6 cards: Card 1 · Visitors today (Vercel Analytics or PostHog) Card 2 · Signups today (PostHog · event = signup_completed) Card 3 · Activation rate 7d (PostHog funnel) Card 4 · New MRR today (Stripe API · subs created) Card 5 · New errors overnight (Sentry API · last 24h) Card 6 · "Latest session replay" (PostHog · embed iframe of latest 1 replay) # DESIGN RULES (Tufte + Few) - 6 KPI cards in a 3×2 grid - Each card: big number + tiny delta vs yesterday (green up · red down) - No 3D effects · no chartjunk · single accent color - Loads in < 2 seconds - Mobile responsive - Auto-refreshes every 5 min STEP 3 · DEPLOY: - Push to my domain at /dashboard - Tell me the URL + how to bookmark on phone home screen - Pin to favicon so it's obvious in tab bar # DELIVERABLE - A live URL I open with my morning coffee - 6 numbers · 5 seconds to read - Mobile-friendly · add to phone home screen # QUALITY BAR - Tufte: would removing any chart/color make it clearer? - Few: can a stranger know what to DO from this dashboard in 30 sec? - Welsh: is this fast enough I'd actually look at it every morning?
Why: Daily dashboard catches issues. Weekly digest catches TRENDS. Auto-emailed every Sunday 9am. No remembering. No skipping.
# ROLE · WORLD-CLASS PANEL 3-expert team: - Lenny Rachitsky — SaaS weekly review framework - Justin Welsh — solo founder operating rhythm - Stephen Few — "Show Me the Numbers" digest design # CONTEXT Based on my Build Sprint app + the tools I just installed — build a Sunday-morning auto-digest emailed to me weekly. # INPUT My email: [paste] My PostHog + Sentry + Stripe API keys: [readonly] Send time: [Sunday 9am my timezone] # YOUR PROCESS STEP 1 · ASK 2 CLARIFYING QUESTIONS: - "Most important metric to lead with?" - "Biggest worry I want flagged if it moves?" Wait. STEP 2 · BUILD scheduled function (Vercel Cron OR Supabase pg_cron): Every Sun 9am: - Pull PostHog stats for week (visitors, signups, activation, retention) - Pull Stripe MRR delta, churn count, failed payments, top customers added - Pull Sentry top 5 errors of the week (by user count) - Compare each to last week (% change) - Generate markdown email with sections: 📈 THE WIN — biggest positive movement ⚠️ THE WORRY — biggest negative or stagnation 🎯 THE 1 THING TO FIX — single recommendation for the week - Add a chart for MRR trajectory (sparkline, no chartjunk) - End with: "open dashboard → [URL]" STEP 3 · SEND via Resend/Postmark to my email STEP 4 · TEST the first send NOW (don't wait until Sunday) # DELIVERABLE - Cron job deployed + verified - Test email landed in my inbox - 3-line "this is what I look at first" Sunday-morning summary # QUALITY BAR - Lenny: does the digest support decisions (not just describe data)? - Welsh: is it short enough I'd actually read it on my phone? - Few: does the WIN/WORRY/FIX structure make priority obvious?
Why: Something breaks at 11pm. You panic. You don't know where to look first. This prompt walks you through triage in 3 minutes. Calm. Methodical. Saves you.
# ROLE You are my SRE/observability triage partner. Calm. Methodical. Panel reference: Charity Majors · Will Larson · Tanya Reilly. # CONTEXT Based on my Build Sprint app + my instrumented stack (Sentry, PostHog, Vercel, Lovable, Supabase, Stripe) — walk me through finding what's broken FAST. Stay calm with me. # INPUT What I observed: [the symptom · user said / what I saw] When it started: [time / event / "I don't know"] What I just deployed (if anything): [paste recent change] Severity I'm feeling: [low / "uh oh" / "everything is on fire"] # YOUR PROCESS · the 3-minute triage ASK 1 question first: "Is anyone currently affected, or did this resolve itself? Is revenue affected?" Then walk me through IN ORDER (skip steps that don't apply): 1 · SENTRY · any new error type in last 24h matching the symptom? Open: sentry.io/issues?statsPeriod=24h&sort=created If yes: open the error · show me top stack frame · suggest fix If no: move to step 2 2 · DEPLOY HISTORY · any deploy in the window when symptom started? Open: Vercel · Lovable · or Git log If yes: candidate to roll back · suggest 1-click revert If no: move to step 3 3 · SUPABASE/DB · any RLS errors / DB timeouts / auth failures? Open: supabase.com/dashboard/[project]/logs If yes: identify the query · suggest fix If no: move to step 4 4 · POSTHOG · funnel drop spike in same time window? Open: my funnel · last 24h vs prior 7d avg If yes: which step? which segment of users? If no: move to step 5 5 · STRIPE · payment failures or webhook delivery issues? Open: stripe.com/dashboard/webhooks If yes: which event · what error · retry? For each step: - Tell me exactly what URL to open - Tell me what to look for - If found: tell me what to do - If not found: move to next step calmly # DELIVERABLE - The root cause (or "I don't know · here's what to investigate next") - The 1 fix to ship now (or the rollback to do) - 1-line post-mortem to add to my Notion (with date + symptom + fix) - A "follow-up next week" note if the root cause isn't fully fixed # TONE Calm. Reassuring. "We'll find it." Don't panic, don't catastrophize. If revenue is affected, prioritize stopping the bleed before root cause.
