# Analytics Event Taxonomy

Use this skill to make product analytics answer decisions instead of generating noisy events.

## Workflow

1. Identify product decisions, lifecycle funnel, entities, identity model, and instrumentation surfaces.
2. Read `references/analytics-event-taxonomy-patterns.md`.
3. Define event names, properties, identity, lifecycle stages, guardrail metrics, and QA checks.
4. Remove vanity or duplicate events.
5. Produce event taxonomy and validation plan.

## When not to use

- Do not use for generic advice the base model already handles without this skill's specific artifact contract.

## Guardrails

- Do not track sensitive data without purpose and privacy review.
- Do not create events without a decision they support.
- Keep names stable, semantic, and versioned when necessary.

## Output format

```text
Decision questions:
Identity model:

Event taxonomy:
- <event_name>: trigger, properties, owner, decision supported

Funnels/cohorts:
- <funnel or cohort>

Quality checks:
- <check>
```
