Advanced: runs the same question under two configurations and diffs the results. Ask one analytics question with a piece of context and without it, and measure what changed. Trigger on "/context-compare", "run it with and without <the definition/context>", "does adding <X> change the answer", "is this context worth it".
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: Context compare (with and without) ## Purpose Measure what a piece of context is doing, instead of asserting it. Run the same question two ways, once without the context (for example, no metric definition) and once with it, and report the delta: did the spread collapse, did the runs start citing the definition, did the verdict go from drifts to stable. The setup whose presence collapses the drift is the context that moves the answer. Convergence is stability, not correctness. ## Invocation `/context-compare "<the question>" --with <the definition> [N]` Default N = 5. The context under test is a meaning-only definition, usually a metric definition: the user states it in conversation, points at a definition YAML file, or names an entry already in the metric dictionary. The baseline is the analyst with that definition absent from the dictionary. Example: `/context-compare "What's our retention rate?" --with "Retention Rate (30d): share of accounts at least 30 days old that were active in the trailing 30 days"` ## How to run it This skill is glue plus bookkeeping, and the whole procedure is manual: you stage the definition …

How to install
mdr add ai-analyst-lab/ai-analyst/context-compare@sha256:29e0009d58fc4b56The 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.
