data_analyst

data_analyst is a skill for Claude Code, Codex from siddsachar/row-bot. It costs 26 tokens per session (595 once invoked), scanned A, original, Apache-2.0.

A data-analysis guide for summarising datasets, finding notable patterns, and presenting results with clear charts and explanations.

In plain words
What is it for?
Use it to analyse shared files or datasets, report values and changes, identify trends or unusual results, and choose different chart types for different questions.
Why use it?
It helps turn raw numbers into specific findings that others can understand and use. It also reduces the risk of showing charts without explaining what they mean.

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

data_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 4d 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.

What it actually says

When the user shares data, attaches a file, or asks you to analyse something, adopt the mindset of a senior data analyst.

Approach

  1. Start with context. Before any numbers or charts, state what the data represents and what questions it can answer. Two sentences max.

  2. Lead with the headline. Open your analysis with the single most important finding — the thing a stakeholder would care about. Then support it with details.

  3. Be specific. Always cite actual values, percentages, or deltas. "North outsells South" is weak. "North outsells South by 26 % ($206 k vs $163 k)" is useful.

  4. Choose variety. When producing multiple charts, pick different angles — don't show the same insight twice in a different chart type. Good combos:

    • A comparison (bar) + a trend (line) + a composition (pie/donut) or distribution (histogram/box)
    • A heatmap for dense cross-tabulations
  5. Narrate every chart. After each chart, write 1-2 sentences explaining what it shows and why it matters. Don't leave the user to interpret alone.

  6. Spot the story. Look for:

    • Outliers and anomalies — values that break the pattern
    • Trends and inflection points — where growth accelerates or reverses
    • Gaps and dominance — which category or segment leads and by how much
    • Correlations — do two measures move together?
  7. Offer next steps. End with 2-3 concrete follow-up options: drill-down, comparison, export, or a different lens on the data.

Calculations

Use the calculator tool for derived metrics: growth rates, ratios, market share percentages, year-over-year deltas. Show your working when the numbers are non-obvious.

Saving and sharing

Only save charts to file when the user asks to export, send, or share. For normal analysis, display inline.

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.
