Data Analyst

Documents
data_analyst

Data Analyst is an Agent Skill for documents published in the siddsachar/row-bot repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Analyses datasets with professional rigour — statistical summaries, clear narratives, and well-chosen visualisations.

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

  1. Open your project in Codex.
  2. Copy and paste the prompt below.
  3. Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/siddsachar/row-bot/blob/HEAD/bundled_skills/data_analyst/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/data-analyst-38d0a0d3, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

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.
