Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00035 | $0.01478 |
| Opus 5 | $0.00017 | $0.00739 |
| Sonnet 5 | $0.00007 | $0.00296 |
| Haiku 4.5 | $0.00003 | $0.00148 |
Grade A, and why
posthog-analytics scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 210 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PostHog Analytics & Session Replay
What's Already Configured
The bootstrap includes a complete PostHog setup with:
- Session Replay - Records user sessions with privacy protections
- Automatic Screen Tracking - Tracks navigation automatically via
ScreenTrackercomponent - Event Tracking - Ready to use via
usePostHog()hook - Privacy Controls - Text inputs and images are masked by default
Files Involved
| File | Purpose |
|---|---|
lib/posthog.ts |
Configuration with session replay plugin |
app/_layout.tsx |
PostHogProvider wrapper and ScreenTracker component |
app.json |
PostHog plugin registration |
.env.example |
Environment variable template |
How Session Replay Works
What Gets Recorded
- ✅ Screen views and navigation
- ✅ Touch interactions (taps, swipes)
- ✅ UI changes and animations
- ✅ Network requests (with
captureNetworkTelemetry: true) - ✅ Console logs (with
captureLog: true)
Privacy Protections
- 🔒 Text inputs masked - All form inputs show as
**** - 🔒 Images masked - Photos and avatars are blurred/hidden
- 🔒 Sensitive data protected - No actual typed content recorded
Recording Behavior
- Starts automatically when app launches
- Continues throughout the session
- Stops when app is closed/backgrounded
- Each session is a separate replay in PostHog dashboard
- Data is compressed and sent in batches (not real-time)
Data Usage
- ~100-500KB per minute of usage
- Throttled to 1 second intervals (
throttleDelayMs: 1000) - Only captures visual changes, not full video
Configuration Options
All settings are in lib/posthog.ts:
| Setting | Default | Purpose |
|---|---|---|
maskAllTextInputs |
true |
Hide all text input content |
maskAllImages |
true |
Blur/hide all images |
captureLog |
true |
Include console logs in replay |
captureNetworkTelemetry |
true |
Track API calls |
throttleDelayMs |
1000 |
Snapshot interval (milliseconds) |
captureNativeAppLifecycleEvents |
true |
Track app open/close/background |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

posthog-analytics is a skill published in the GitHub repository Ampli-Group/agentic-mobile-blueprint (4 stars, last pushed 1mo ago), licensed MIT. It adds 35 tokens to every session and 1,478 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
