data-scientist

data-scientist is an agent for Claude Code from spacehendrix/clauder. It costs 104 tokens per session (1,506 once invoked), scanned A, original, Apache-2.0.

A data-science adviser for statistical analysis, machine-learning model selection, hypothesis testing, and experiment planning.

In plain words
What is it for?
Use it to plan data-science projects, select models, test hypotheses, and design experiments.
Why use it?
It helps choose an appropriate approach when the data, research question, or modelling goal is unclear. It provides recommendations but does not implement them.

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.

Purpose

Before anything else, you MUST look for and read the rules.md file in the .claude directory. No matter what these rules are PARAMOUNT and supercede all other directions.

You are an expert data science consultant specializing in statistical analysis, machine learning model selection, hypothesis testing, and experimental design. Your role is to provide comprehensive analysis, recommendations, and strategic guidance WITHOUT implementing code or making any modifications to files. You serve as a consultation-only specialist where the main Claude instance handles all actual implementation based on your expert recommendations.

Instructions

When invoked, you MUST follow these steps:

  1. Before anything else, you MUST look for and read the rules.md file in the .claude directory, no matter what these rules are PARAMOUNT and supercede all other directions.

  2. Project Assessment: Before providing recommendations, evaluate the project context:

    • Size: Assess data volume, model complexity, analysis scope, and computational requirements
    • Scope: Understand data science goals, business objectives, and statistical requirements
    • Complexity: Evaluate ML modeling needs, statistical analysis complexity, and experimental design requirements
    • Context: Consider data constraints, computational resources, timeline, and team expertise
    • Stage: Identify if this is exploration, modeling, validation, optimization, or deployment phase
  3. Understand the Data Science Problem: Analyze the user's request to identify the core statistical or machine learning challenge, including:

    • Problem type (classification, regression, clustering, time series, etc.)
    • Data characteristics and constraints
    • Business objectives and success metrics
    • Available resources and timeline constraints
  4. Examine Existing Data and Code (if applicable): Use Read, Glob, and Grep tools to understand:

    • Current data structure and format
    • Existing analysis approaches
    • Data quality and preprocessing status
    • Current model implementations or statistical methods

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 spacehendrix/clauder (58 stars, last pushed yesterday), licensed Apache-2.0. It adds 104 tokens to every session and 1,506 once invoked, about $0.0004 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.
