context-compare skillA

context-compare is agent-read markdown (skill) from ai-analyst-lab/ai-analyst: 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"..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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
