scikit-survival

scikit-survival is a skill for Claude Code, Codex from Lord1Egypt/scientific-agent-toolkit. It costs 91 tokens per session (3,605 once invoked), scanned A, a copy of scikit-survival, MIT.

A Python toolkit for survival analysis, which studies how long it takes for an event to occur when some observations have not experienced the event yet. It includes statistical and machine-learning models for this time-to-event data.

In plain words
What is it for?
Use it to estimate survival curves, fit Cox models, train survival forests or support-vector machines, analyse competing risks, and evaluate predictions.
Why use it?
It handles censored records, such as patients whose follow-up ended before an outcome occurred, which ordinary prediction methods do not handle well.

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

scikit-survival 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 9d 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.

scikit-survival: Survival Analysis in Python

Overview

scikit-survival is a Python library for survival analysis built on top of scikit-learn. It provides specialized tools for time-to-event analysis, handling the unique challenge of censored data where some observations are only partially known.

Survival analysis aims to establish connections between covariates and the time of an event, accounting for censored records (particularly right-censored data from studies where participants don't experience events during observation periods).

When to Use This Skill

Use this skill when:

  • Performing survival analysis or time-to-event modeling
  • Working with censored data (right-censored, left-censored, or interval-censored)
  • Fitting Cox proportional hazards models (standard or penalized)
  • Building ensemble survival models (Random Survival Forests, Gradient Boosting)
  • Training Survival Support Vector Machines
  • Evaluating survival model performance (concordance index, Brier score, time-dependent AUC)
  • Estimating Kaplan-Meier or Nelson-Aalen curves
  • Analyzing competing risks
  • Preprocessing survival data or handling missing values in survival datasets
  • Conducting any analysis using the scikit-survival library

Core Capabilities

1. Model Types and Selection

scikit-survival provides multiple model families, each suited for different scenarios:

Cox Proportional Hazards Models

Use for: Standard survival analysis with interpretable coefficients

  • CoxPHSurvivalAnalysis: Basic Cox model
  • CoxnetSurvivalAnalysis: Penalized Cox with elastic net for high-dimensional data
  • IPCRidge: Ridge regression for accelerated failure time models

See: references/cox-models.md for detailed guidance on Cox models, regularization, and interpretation

Ensemble Methods

Use for: High predictive performance with complex non-linear relationships

  • RandomSurvivalForest: Robust, non-parametric ensemble method
  • GradientBoostingSurvivalAnalysis: Tree-based boosting for maximum performance
  • ComponentwiseGradientBoostingSurvivalAnalysis: Linear boosting with feature selection
  • ExtraSurvivalTrees: Extremely randomized trees for additional regularization

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.
