What problem does it solve?
This Skill prevents user-facing features from shipping without reliable, privacy-preserving measurement, ensuring product health, creator conversion, game engagement, acquisition, retention, and build economics remain answerable from telemetry.
Core Features & Use Cases
- Telemetry Architecture: Coordinate browser, API, storage, iframe, visit, and creator telemetry changes across their required contracts.
- Privacy and Safety Invariants: Preserve anonymous play and visit streams, ephemeral correlation, coarse acquisition data, hostile-input validation, rate limits, caps, and aggregate-only reporting.
- Event Vocabulary and Metrics: Extend stable event names, funnel stages, game health signals, shared-zone outcomes, scorecards, and creator metrics without breaking existing analyses.
- Use Case: Use this Skill when adding or changing play, creation, sign-in, sharing, party mode, dashboards, or any metric so the implementation includes the required events, validation, aggregation, retention updates, and tests.
Quick Start
Use the product-instrumentation skill to review this feature change, identify the affected measurement questions, update every required telemetry contract, and list the tests and aggregates needed before release.
