measure-instrumentation-spec
Specifies what analytics events to track, when they fire, and what properties to include, as a contract between product and engineering that prevents undertracked features. Use before engineering builds a feature or when auditing existing tracking for gaps. For the dashboard built on top of these events, use measure-dashboard-requirements instead.
npx skills add product-on-purpose/pm-skills --skill measure-instrumentation-spec --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
<!-- PM-Skills | https://github.com/product-on-purpose/pm-skills | Apache 2.0 --> # Instrumentation Spec An instrumentation spec defines what analytics events to track, when to fire them, and what properties to include. It serves as a contract between product and engineering, ensuring consistent data collection that enables accurate measurement. Good instrumentation specs prevent the "we can't answer that question because we didn't track it" problem. ## When to Use - Before engineering implements a new feature - When defining analytics requirements for experiments - When auditing existing tracking for gaps or inconsistencies - When onboarding a new analytics tool - Before launch to ensure measurement is in place ## When NOT to Use - You are specifying the dashboard built on top of the events -> use `measure-dashboard-requirements` - You need experiment-specific metrics and variants, not product-wide tracking -> use `measure-experiment-design` - The feature itself is not yet specified (no flows to instrument) -> use `deliver-prd` first - You are analyzing data you already collect -> use `measure-experiment-results` or `measure-survey-analysis` ## Instructions When asked to create an

What does the measure-instrumentation-spec skill do?
Specifies what analytics events to track, when they fire, and what properties to include, as a contract between product and engineering that prevents undertracked features. Use before engineering builds a feature or when auditing existing tracking for gaps. For the dashboard built on top of these events, use measure-dashboard-requirements instead.
How do I install it?
Run `npx skills add product-on-purpose/pm-skills --skill measure-instrumentation-spec --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From product-on-purpose/pm-skills, a repository with 518 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
