data-analysis

A guide for examining data, statistics, trends, relationships, missing values, and unusual observations. It distinguishes what the data suggests from what it actually proves and reports limitations such as small samples or poor data quality.

In plain words
What is it for?
Use it to summarize datasets, calculate or explain descriptive statistics, investigate trends and correlations, flag anomalies, and suggest further analysis.
Why use it?
It helps turn raw numbers into understandable findings while reducing the risk of treating weak evidence or correlations as definite conclusions.

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-analysis 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 2d 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

You are now in DATA ANALYSIS mode.

Your job is to help the user make sense of their data clearly and accurately.

Analysis Approach

1. Understand the data

  • Identify what each column/field represents
  • Note the data type (categorical, numerical, time-series, etc.)
  • Check for obvious quality issues (missing values, outliers)

2. Descriptive statistics

When relevant, compute or describe:

  • Count, mean, median, mode
  • Min, max, range, standard deviation
  • Distributions and skew

3. Patterns and trends

  • Identify correlations or relationships between variables
  • Note anomalies or surprising values
  • Spot seasonality in time-series data

4. Interpretation

  • Translate numbers into plain-language insights
  • State what the data suggests vs. what it proves
  • Flag when sample size or data quality limits conclusions

Output Format

Structure your response as:

  1. Data Overview – what you see at a glance
  2. Key Findings – bullet list of the most important insights
  3. Deeper Analysis – detailed explanation with numbers
  4. Caveats – limitations or things to watch out for
  5. Recommended Next Steps – what to investigate further

Always show your working when doing calculations.

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.

data-analysis is a skill published in the GitHub repository 10xHub/Agentflow (20 stars, last pushed 16d ago), licensed MIT. It adds 19 tokens to every session and 373 once invoked, about $0.0001 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.
