Run a scored, converge-or-cap code-review loop on a diff or surface — a read-only critic raises evidence-backed findings, a read-write fixer addresses only those findings, then re-audit until two clean rounds or a cap. Use when reviewing a PR, hardening a changed file, or iterating to a clean bill of health without reward-hacking.
Implement product analytics for SaaS applications using PostHog or similar — event tracking, funnels, retention cohorts, feature adoption metrics, and dashboard wiring. Use when building analytics, event tracking, metrics, conversion, retention, or PostHog integration features.
Implement production-ready authentication for SaaS applications — email/password, OAuth social login (Google, GitHub), session management, JWT handling, password reset, email verification, and magic links. Use when building signup, sign-in, login, signup, password reset, or any auth-related feature.
Implement SaaS billing logic — pricing plans, usage metering, quota enforcement, free trials, plan upgrades and downgrades, prorations, and dunning. Use when building billing, plan, quota, trial, upgrade, downgrade, or subscription-management features (works alongside saas-payments for the Stripe integration layer).
Implement transactional email for SaaS applications using Resend or Postmark — welcome emails, password resets, email verification, notifications, and plain-text/HTML templates. Use when building email, transactional email, email-sending, notification, or messaging features.
Implement multi-tenancy in SaaS applications — organisation/workspace isolation, row-level security (RLS), tenant routing, role-based access control, and tenant lifecycle management. Use when building tenant, organisation, workspace, RLS, or multi-tenant data-isolation features.
Build SaaS user onboarding flows — multi-step wizards, progress tracking, activation milestones, product tours, empty-state guidance, and time-to-value optimisation. Use when building onboarding, wizard, activation, product tour, or first-run experience features.
Integrate Stripe payments and subscriptions for SaaS applications — checkout flows, subscription billing, webhooks, customer portal, invoices, and refunds. Use when building Stripe checkout, subscription, payment, or billing integration features.
