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 | $0.00107 | $0.02922 |
| Opus 5 | $0.00053 | $0.01461 |
| Sonnet 5 | $0.00021 | $0.00584 |
| Haiku 4.5 | $0.00011 | $0.00292 |
Grade A, and why
event-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 today.
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.

Event Analytics
Overview
Events are the atomic unit of customer understanding. Every signup, click, feature use, upgrade, and cancellation is an event. The mistake: tracking events haphazardly ("track everything!") with no taxonomy, creating a data swamp instead of a data pipeline. This skill covers event analytics across every GTM system — how to design an event taxonomy, implement tracking, and unify event data across your stack to build a complete customer picture.
Authoritative Foundations
- Segment — Customer Data Platform (CDP) and event taxonomy — Customer Data Platform (CDP) and event taxonomy
- Amplitude — Behavioral analytics and event design — Behavioral analytics and event design
- Mixpanel — Product analytics and event-based reporting — Product analytics and event-based reporting
- Intercom — Event-driven messaging and automation — Event-driven messaging and automation
- Avo — Event taxonomy and governance — Event taxonomy and governance
- Snowplow — Open-source event pipeline — Open-source event pipeline
When to Use
Trigger phrases: "event analytics setup", "customer event tracking", "implement Segment", "Amplitude setup for SaaS", "event taxonomy design", "customer data pipeline", "product analytics events", "Intercom events", "event-driven workflows"
Step-by-Step Process
Phase 1: Event Taxonomy Design
The 4 event types (Segment spec):
- Identify: Who is the user?
identify(userId, traits) - Track: What did they do?
track(eventName, properties) - Page: What page did they view?
page(name, properties) - Group: What account/workspace are they in?
group(groupId, traits)
Event naming convention (object-action framework):
Format: [Object] [Action] (Past tense. Write events as things that HAPPENED.)
Good: "Project Created" "Invoice Paid" "Campaign Sent"
Bad: "createProject" "user_clicked_button" "page3-conversion-v2"
Rules:
- Title case: "Signed Up" not "signed_up"
- Past tense: "Viewed" not "View"
- Object first: "Report Exported" not "Exported Report"
- No technical jargon: "Payment Completed" not "stripe_webhook_200"
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

event-analytics is a skill published in the GitHub repository LeadMagic/gtm-skills (46 stars, last pushed 2d ago), licensed MIT. It adds 107 tokens to every session and 2,922 once invoked, about $0.0005 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 2026-08-30.
