Never present a metric or number in isolation; anchor every number to a comparison (prior period, benchmark, or another segment) or state that none is available. Use every time you show a number: rates, counts, revenue, averages, query results, chart labels, summary stats. Trigger on output containing "the rate is", "we saw", "total", "average", "conversion", "revenue", "users", "sessions", "churn", "AOV", "NPS", or any figure pulled from data.
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: Always Compare ## Purpose A number alone is not an insight. "Conversion rate is 3.2%" tells the reader nothing actionable — they cannot tell if that is a crisis or a record high. This skill enforces one rule: **every metric ships with a comparison.** ## When to Use Before presenting ANY number to the user — in chat, in a report, in a chart caption, in a Slack message, or on a slide. This runs on every analysis output, alongside `question-framing` (which runs at the start; this one runs at the end). ## The Rule > **Never show a number alone. Anchor it to at least one comparison.** Pick the comparison that best serves the decision. In priority order: | # | Comparison Type | Use When | Example | |---|---|---|---| | 1 | **vs. prior period** | The question is "is this changing?" | "down from 4.1% last month" | | 2 | **vs. benchmark / average** | The question is "is this normal?" | "below the 3.8% site-wide average" | | 3 | **vs. another segment** | The question is "who is affected?" | "vs. 5.4% on desktop" | **Two comparisons beat one.** A prior-period delta plus a benchmark tells the reader both the direction and the altitude. Use both when you have both. …

How to install
mdr add ai-analyst-lab/ai-analyst/always-compare@sha256:e6073d07e1a8639eThe line at the top of this page pins the label git:20260827.7ff2e25, 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.
