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 | $0.00036 | $0.00828 |
| Opus 5.5 | $0.00014 | $0.00331 |
| Sonnet 5.5 | $0.00007 | $0.00166 |
| Haiku 4.5 | $0.00004 | $0.00083 |
Grade A, and why
analytics-tracking 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 1mo 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.

Analytics Tracking
You can't improve what you don't measure — but measure what matters, not everything.
1. Analytics Strategy
What to Track
| Level | Metrics |
|---|---|
| Business | Revenue, MRR, churn rate |
| Product | DAU/WAU/MAU, activation rate |
| Feature | Adoption, usage frequency |
| Technical | Page load, errors, Core Web Vitals |
Framework: AARRR
| Stage | Key Events |
|---|---|
| Acquisition | page_view, utm_source, referral |
| Activation | sign_up, onboarding_complete, first_value |
| Retention | login, feature_used, session_count |
| Revenue | plan_upgraded, payment_complete |
| Referral | invite_sent, share_clicked |
2. Event Design
Naming Convention
| Convention | Example |
|---|---|
| Object + Action | button_clicked, form_submitted |
| Consistent case | snake_case for events |
| Descriptive | checkout_started not click1 |
| Grouped | Prefix by feature: auth_login, auth_signup |
Event Properties
| Property | Always Include |
|---|---|
| userId | If authenticated |
| timestamp | When it happened |
| context | Page, source, device |
| value | Revenue, quantity if applicable |
3. Tool Selection
| Tool | Best For | Price |
|---|---|---|
| GA4 | Web traffic, SEO | Free |
| PostHog | Product analytics, self-host | Free tier |
| Mixpanel | Event-based analysis | Free tier |
| Amplitude | Product intelligence | Free tier |
| Plausible | Privacy-focused, simple | Paid |
4. GA4 Setup
Key Configurations
| Setting | What |
|---|---|
| Enhanced measurement | Auto-track scrolls, outbound clicks |
| Custom events | Business-specific actions |
| Conversions | Mark key events as conversions |
| Audiences | Segment users for analysis |
| Data retention | Set to 14 months (max free) |
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.
- 1mo ago First seen · 127 lines · 36 tokens per session scan A a0b91c0e3258
analytics-tracking is a skill published in the GitHub repository hoangatg/ai-agent-toolkit (1 stars, last pushed 7mo ago), licensed MIT. It adds 36 tokens to every session and 828 once invoked, about $0.0001 per session on Opus 5.5. 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.
