What it does

Survival Analysis Tools is an agent skill from DrugClaw/DrugClaw. Survival and time-to-event workflow guide for Kaplan-Meier summaries, log-rank tests, and Cox proportional hazards models with reproducible outputs. Use when the user asks for time-to-event analysis, censored data summaries, hazard ratios, or survival-group comparison for research datasets.

Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `templates/survival_analysis.py`).

It sits in Research & Science. The repository describes itself as: 💊 AI Research Assistant for Accelerated Drug Discovery. 🦞. The licence is Apache-2.0.

When your agent uses it

The user asks for time-to-event analysis
Censored data summaries
Survival-group comparison for research datasets

Example prompts

“/survival-analysis-tools”

Requirements

Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

Confirm the time and event coding first.
Generate group-level Kaplan-Meier summaries before fitting adjusted models.
Add Cox covariates only after checking the columns and coding logic.
Export both tables and a survival plot.
Treat hazard ratios as model-based associations, not automatic causal effects.

What it can do on your machine

Read from SKILL.md and the folder at commit 960a6e0. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (Python), which the agent can run.
Shell commands in SKILL.md call:
- python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Survival Analysis Tools loads about 743 tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 220 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~79
When it runs · the whole SKILL.md, loaded when a task matches: ~743

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Survival Analysis Tools

Use this skill when the user needs time-to-event analysis with censoring-aware summaries.

Typical triggers:

Kaplan-Meier curves or survival probability tables
log-rank comparison between treatment arms
Cox proportional hazards regression with hazard ratios
time-to-event or progression-free survival analysis
censored cohort summaries for translational or clinical research

Environment Check

bash

which python3 || true
python3 - <<'PY'
mods = ["numpy", "pandas", "statsmodels", "matplotlib"]
for name in mods:
    try:
        __import__(name)
        print(f"{name}: ok")
    except Exception as exc:
        print(f"{name}: missing ({exc})")
try:
    import sksurv
    print("sksurv: optional-ok")
except Exception as exc:
    print(f"sksurv: optional-missing ({exc})")
PY

The bundled template runs on the stable statsmodels baseline. Advanced machine-learning survival models from scikit-survival remain optional and should only be claimed when the environment actually has them.

Bundled Asset

templates/survival_analysis.py

Preferred Workflow

Confirm the time and event coding first.
Generate group-level Kaplan-Meier summaries before fitting adjusted models.
Add Cox covariates only after checking the columns and coding logic.
Export both tables and a survival plot.
Treat hazard ratios as model-based associations, not automatic causal effects.

Kaplan-Meier And Cox Baseline

bash

python3 templates/survival_analysis.py \
  --input survival/nsclc.csv \
  --time-column pfs_days \
  --event-column progressed \
  --group-column arm \
  --covariate age \
  --covariate stage_numeric \
  --covariate biomarker_score \
  --plot-output survival/nsclc_km.png \
  --km-output survival/nsclc_km.csv \
  --cox-output survival/nsclc_cox.csv \
  --summary survival/nsclc_summary.json

Use this for:

group-level median survival summaries
Kaplan-Meier plots
log-rank p-values when a group column is present
Cox proportional hazards coefficients and hazard ratios

Boundary

The bundled baseline does not provide random survival forests, gradient-boosted survival models, or integrated Brier score pipelines out of the box. If the user explicitly needs those, confirm that scikit-survival is available first.

For general hypothesis tests or non-survival regression, activate stat-modeling-tools. For figures beyond the bundled KM plot, activate scientific-visualization-tools. For study-design or endpoint-planning support, activate clinical-research-tools.
