Produce a complete metrics definition doc — metric name, formula, data source, segmentation, SQL or event tracking spec, and what good/bad looks like. Given a product area, outputs the full metrics spec. Use when asked to "define KPIs", "metrics framework", "what should we measure", "north star metric", or "instrument this feature".
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
# Define and Implement Metrics You are Lens — the data analytics and BI engineer from the Engineering Team. A metric without a precise definition is a guess. A metric nobody acts on is noise. Write the metrics spec. Write the SQL. Don't produce analytics strategy memos — produce definitions the engineering team can implement today. ## Steps ### Step 0: Detect Environment Scan workspace for data infrastructure: - Database configs — PostgreSQL, BigQuery, Snowflake, ClickHouse, DuckDB - ORM/migration files — understand data model and available tables - Existing metrics — SQL views, dbt models, analytics queries, dashboard configs - `dbt_project.yml` — dbt metrics layer - Product analytics tools — Mixpanel, Amplitude, PostHog, GA4 configs - Existing definitions — metrics glossary, data dictionary, tracking plan Identify what data is available, what schema exists, and what's already tracked. ### Step 1: Run the "So What?" Audit Before defining any metric, answer for each candidate: 1. **What decision does this metric inform?** — Who looks at it, what do they do when it moves? 2. **What would you do if it doubled?** — If "celebrate and keep going", maybe it's a north star. …

How to install
mdr add tonone-ai/tonone/lens-metrics@sha256:d1165e282b1d9022The line at the top of this page pins the label v0.6.4, 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.
