Now I have all the information needed to provide a comprehensive evaluation. Let me write the PR evaluation report:

PR Evaluation Report

Summary

This PR integrates PostHog analytics into a TanStack Router file-based SaaS application. It adds posthog-js dependency, wraps the app with PostHogProvider, implements user identification on login/logout, and tracks 11 custom events across invoice management, user authentication, and CTA interactions.

Files changed	Lines added	Lines removed
12	+601	-17

Confidence score: 3/5 🤔

• Missing page view tracking: No automatic pageview capture configured - TanStack Router route changes won't be tracked. Need to add capture_pageview: true or implement manual tracking using router hooks. [MEDIUM]
• Missing reverse proxy: No proxy configuration to circumvent ad blockers - events may be blocked for significant portion of users. [MEDIUM]
• useEffect dependency arrays incomplete: Several tracking effects have incomplete dependency arrays (e.g., posthog missing from deps in _auth.profile.tsx, dashboard.invoices..tsx). This is a React best-practices issue. [LOW]

File changes

Filename	Score	Description
package.json	5/5	Correctly adds posthog-js ^1.345.5 as dependency
pnpm-lock.yaml	5/5	Lock file properly updated with PostHog and OpenTelemetry dependencies
.gitignore	5/5	Correctly adds .env to prevent secrets from being committed
src/vite-env.d.ts	5/5	Proper TypeScript type definitions for Vite environment variables
src/routes/__root.tsx	4/5	PostHogProvider correctly wraps app, but missing capture_pageview config
src/routes/login.tsx	5/5	Proper identify() on login and reset() on logout with event captures
src/routes/index.tsx	5/5	CTA click tracking with location properties
src/routes/_auth.profile.tsx	4/5	Profile view and upgrade tracking; incomplete useEffect deps
src/routes/dashboard.invoices.index.tsx	5/5	Invoice creation tracking with proper context data
src/routes/dashboard.invoices..tsx	4/5	Comprehensive invoice tracking; incomplete useEffect deps
src/routes/dashboard.users.user.tsx	4/5	Team member view tracking; incomplete useEffect deps
posthog-setup-report.md	4/5	Helpful documentation but contains truncated API key in example

App sanity check: 4/5 ✅

Criteria	Result	Description
App builds and runs	Yes	No syntax errors, proper imports, TypeScript definitions added
Preserves existing env vars & configs	Yes	Only adds new PostHog env vars, existing configs unchanged
No syntax or type errors	Yes	All TypeScript types properly defined in vite-env.d.ts
Correct imports/exports	Yes	PostHogProvider and usePostHog correctly imported from posthog-js/react
Minimal, focused changes	Yes	Changes limited to PostHog integration, no unrelated modifications

Issues

• Incomplete useEffect dependency arrays: Multiple files have useEffect hooks with incomplete dependency arrays (missing posthog in deps). While this works due to PostHog hook stability, it violates React exhaustive-deps best practices. [LOW]

Other completed criteria

• Environment variables documented in posthog-setup-report.md
• .env added to .gitignore for security
• No hardcoded API keys in source files
• Existing app code and business logic preserved
• Import statements are correct and functional

PostHog implementation: 3/5 ⚠️

Criteria	Result	Description
PostHog SDKs installed	Yes	posthog-js ^1.345.5 added to dependencies
PostHog client initialized	Yes	PostHogProvider in __root.tsx with env vars for apiKey and api_host
capture()	Yes	11 custom events captured across multiple components
identify()	Yes	User identified on login with username, reset() called on logout
Error tracking	Yes	capture_exceptions: true enabled in PostHogProvider options
Reverse proxy	No	No proxy configured - events sent directly to PostHog will be blocked by ad blockers

Issues

• No reverse proxy configured: The vite.config.js doesn't include a proxy configuration to route PostHog requests through the app's domain. A significant percentage of users with ad blockers will have their analytics blocked. Should add Vite server proxy config or configure at deployment level. [MEDIUM]
• No automatic page view tracking: The PostHogProvider doesn't enable capture_pageview: true, and there's no manual pageview tracking using TanStack Router's navigation hooks. Route transitions won't be tracked. [MEDIUM]

Other completed criteria

• API key properly loaded from environment variable (VITE_PUBLIC_POSTHOG_KEY)
• API host properly configured (VITE_PUBLIC_POSTHOG_HOST)
• Debug mode enabled only in development (import.meta.env.DEV)
• No PII sent in event properties (only username which is user-provided)
• Proper session reset on logout with posthog.reset()

PostHog insights and events: 4/5 ✅

Filename	PostHog events	Description
login.tsx	user_logged_in, user_logged_out	Core authentication funnel events with username property
index.tsx	cta_dashboard_clicked, cta_signin_clicked, pending_invoice_clicked	Homepage CTA effectiveness tracking with location context
dashboard.invoices.index.tsx	invoice_created	Conversion event with invoice_id and invoice_title
dashboard.invoices..tsx	invoice_viewed, invoice_updated, invoice_notes_toggled	Invoice funnel tracking with amount, status, and visibility
dashboard.users.user.tsx	team_member_viewed	Team collaboration tracking with member details and role
_auth.profile.tsx	profile_settings_viewed, upgrade_clicked	Upgrade intent and settings engagement tracking

Issues

• No pageview events: Without page view tracking, user navigation patterns and session context are missing - limits funnel analysis accuracy. [MEDIUM]

Other completed criteria

• Events represent meaningful user actions (logins, invoice CRUD, CTA clicks)
• Events are enriched with contextual properties (invoice_id, invoice_status, location)
• Event naming follows consistent snake_case convention
• Events support building funnels (login → view → create)
• Upgrade intent tracking enables conversion analysis
• Duplicate tracking prevented with useRef pattern
