Define any metric completely with a standardized template: calculation, denominator, time window, filters, interpretation. Trigger on "define this metric", "how should we measure X?", "what's the right way to calculate Y?", "document our metrics", "create a metric definition", "different teams are measuring this differently", or when a metric is used in analysis without a clear specification.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Skill: Metric Spec ## Purpose Define any metric clearly and completely using a standardized template so there is no ambiguity about what is being measured, how it's calculated, or how to interpret it. ## When to Use Apply this skill when defining a new metric, when a metric is referenced without a clear definition, or when different people are using the same metric name to mean different things. Every metric used in an analysis should have a spec. ## Instructions ### Metric Spec Template ```markdown ## Metric: [Name] ### Definition **Plain English:** [One sentence a non-technical person can understand] **Formula:** [Exact calculation] **Owner:** [team or person accountable for this metric] **Granularity:** [the grain it is reported at: per user / per order / daily / weekly ...] ### Components | Component | Definition | Source | |-----------|-----------|--------| | **Numerator** | [What's being counted/summed in the top] | [Table.column] | | **Denominator** | [What's being counted in the bottom (if ratio)] | [Table.column] | | **Unit of analysis** | [What does one row represent?] | [e.g., per user, per session, per order] | ### Segmentation Dimensions …

How to install
mdr add ai-analyst-lab/ai-analyst/metric-spec@sha256:47ad17306d80ba09The line at the top of this page pins the label git:20260902.b370de6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
