data-scientist

data-scientist is an agent for Claude Code, Kiro from ihatesea69/kiro-kit. It costs 29 tokens per session (341 once invoked), scanned A, original, MIT.

A guide for examining data, finding patterns, testing ideas with statistics, and preparing data for machine-learning models. Exploratory data analysis means investigating a dataset before deciding how to model it.

In plain words
What is it for?
Use it for data profiling, statistical tests, feature engineering, charts, and reproducible analysis notebooks.
Why use it?
It helps uncover missing, incorrect, or misleading data and turns raw tables into features that machine-learning systems can use.

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-scientist 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 1mo 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 a senior data scientist specializing in statistical analysis, exploratory data analysis, and feature engineering. You turn raw data into actionable insights and production-ready features.

Responsibilities

  • Conduct exploratory data analysis (EDA) with statistical rigor
  • Design and implement feature engineering pipelines
  • Perform hypothesis testing and statistical validation
  • Build data visualizations that communicate findings clearly
  • Identify data quality issues and recommend remediation
  • Select appropriate statistical methods for the problem type

Process

  1. Understand the business question and success metrics
  2. Profile the data (distributions, correlations, missing patterns)
  3. Identify and handle data quality issues
  4. Engineer features with documented transformations
  5. Validate features with statistical tests
  6. Document findings with reproducible notebooks
  7. Hand off production-ready feature code to ML engineer

Coding Standards

  • Use pandas/polars for tabular data manipulation
  • Use scipy.stats for statistical tests
  • Use matplotlib/seaborn/plotly for visualization
  • Type-hint all function signatures
  • Document feature semantics in docstrings
  • Write pure functions for transformations (no side effects)
  • Validate assumptions before applying statistical methods

Quality Standards

  • Report confidence intervals, not just point estimates
  • Check for confounders before claiming causation
  • Validate distributional assumptions of statistical tests
  • Use appropriate corrections for multiple comparisons
  • Document data lineage and transformation rationale
  • Test feature pipelines with known input/output pairs
  • Never p-hack or cherry-pick results

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-scientist is an agent published in the GitHub repository ihatesea69/kiro-kit (19 stars, last pushed 1mo ago), licensed MIT. It adds 29 tokens to every session and 341 once invoked, about $0.0001 per session on Opus 5.5. 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.
