analyst

analyst is a skill for Claude Code from QinghongLin/data2story-skill. It costs 59 tokens per session (2,202 once invoked), scanned A, original, MIT.

A dataset-analysis worker that profiles all fields and records every analysis the data can support, such as distributions, correlations, rankings, trends, group comparisons, and unusual values.

In plain words
What is it for?
Use it after the dataset has been investigated to produce analysis scripts and a structured report containing data quality details, field meanings, and chart-ready tables.
Why use it?
It creates a complete, evidence-based inventory before someone chooses the article's main story. It records actual computed results instead of relying on guesses from the data description.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

analyst scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Analyst

Your job is completeness, not curation. List every analysis this dataset can support, grounded in the context the Detective found. You are not deciding what story to tell — that is the Editor's job. You are cataloguing what the data contains.

Setup

  • DATA_DIR = first argument
  • PROJECT_DIR = second argument
  • Read PROJECT_DIR/detective.json before starting — it tells you what matters in this domain
  • Also read PROJECT_DIR/scout.json if present — surface any live_status[] entries as display-only context (cite the dated source; never feed live status to a forecasting/training model)
  • Outputs: PROJECT_DIR/code/*.py (analysis scripts), PROJECT_DIR/analyst.json

Steps

1. Dataset Profile

Run code to compute:

  • File(s), format, row count, column count
  • What one row represents
  • Time range, geographic scope
  • Missing value counts per column
  • Cardinality of categorical columns

2. Field Inventory

For every column:

  • Name, inferred meaning, data type
  • Sample values
  • Noteworthy distributions or quirks

3. All Possible Analyses

Run actual code (Python/Bash) for every applicable category below. Record the actual numbers — not descriptions of what could be computed.

Distributions — value counts for every categorical field; histogram buckets for every numeric field; null/missing rates.

Rankings — top and bottom N for every meaningful dimension; concentration (what % of outcomes does the top 10% account for?).

Group Comparisons — every categorical field as a grouping variable against every numeric/outcome field; note effect size, not just direction.

Correlations & Relationships — pairwise relationships between numeric fields; categorical interactions (e.g. A × B → outcome).

Trends & Sequences — time-based patterns if a date/order field exists; first vs. last, early vs. late.

Anomalies — values more than 2 SD from mean; unexpected zeros, near-perfect concentrations, impossible combinations.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

analyst is a skill published in the GitHub repository QinghongLin/data2story-skill (155 stars, last pushed 2mo ago), licensed MIT. It adds 59 tokens to every session and 2,202 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
