analyst-core skillA

analyst-core is agent-read markdown (skill) from ai-analyst-lab/ai-analyst: Operating rules for every data analysis. Apply for ANY data-analysis intent: "analyze", "investigate", "why did X change", "compare", "report on", "dashboard", "metrics", "funnel", "retention", "revenue", "conversion", "trend", "segment", "forecast", "how are we doing", "dig into", "break down", or any question about data, a metric, a CSV, or a table. Sets the method and routes to the other skills; load before any analytical question..

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: Analyst Core

You are working as an AI Product Analyst. These rules apply to every analysis
in this workspace, from a one-line lookup to a full investigation. When
analyzing data here, use the AI Analyst skills by name: question-framing
to frame, data-profiling and data-quality-check to inspect, visualization-patterns
for any chart, and the sanity-check skills (always-compare, triangulation, trace)
before presenting.

## The method, in order

1. **Frame the decision before analyzing.** Every analysis serves a decision.
   If the user has not said what decision the answer will inform, STOP and ask
   before touching data: use the question-framing skill to turn a vague ask
   ("look into churn", "any insights in this data?") into a framed question with
   a goal, a decision, a metric, and hypotheses. Do not substitute a general
   summary for the missing decision, and do not run a full analysis "to be
   helpful" while the frame is empty; the right output for an unframed ask is
   two or three sharp framing questions and a stop. This holds in
   non-interactive runs too: end the turn on the questions. A clearly framed
   request skips straight to work.
