neurokit2

neurokit2 is a skill for Claude Code from K-Dense-AI/scientific-agent-skills. It costs 63 tokens per session (3,503 once invoked), scanned A, original, MIT.

A Python toolkit for reproducible research with physiological time-series data, such as heart, breathing, or other body signals. It helps preprocess signals, detect events and intervals, align multiple signals, and measure variability or complexity.

In plain words
What is it for?
Use it to build or audit research workflows for biosignal cleaning, event detection, interval analysis, multimodal alignment, variability measures, and complexity analysis.
Why use it?
It provides structured analysis steps for noisy biosignal data, reducing ad hoc processing and making methods easier to inspect and repeat. Its results are not medical diagnoses or treatment advice.

About the project

Scientific Agent Skills is a collection of reusable procedures that give AI agents capabilities for scientific research across areas such as biology, chemistry, medicine, and drug discovery. It is used by researchers and by people building AI scientist workflows with compatible coding agents. The catalogue contains many of the project's skills and supporting instructions.

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

neurokit2 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.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/_common.py, scripts/ecg_hrv_pipeline.py, scripts/eda_pipeline.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

NeuroKit2

Scope and evidence cutoff

Use this skill for method-aware, reproducible biosignal research with NeuroKit2. The snapshot was checked on 2026-07-23 against:

  • stable PyPI 0.2.13, released 2026-03-02;
  • Python metadata (>=3.10; classifiers 3.10–3.14) and wheel dependencies;
  • GitHub release notes/tags, NEWS.rst, source at tag v0.2.13;
  • official API pages/examples (the live site identified itself as 0.2.13.dev214); and
  • pinned 0.2.13 runtime signatures and synthetic output schemas.

The live documentation can be ahead of the stable wheel. Prefer the pinned runtime for reproducible work and name both versions if consulting development docs.

Boundary

NeuroKit2 is a research and educational toolbox. Do not present its output as:

  • a diagnosis, treatment recommendation, patient-monitoring decision, or alarm;
  • validation, certification, or regulatory evidence for a medical device; or
  • proof that a physiological construct is measured validly in a new sensor, protocol, environment, population, or disease group.

Validate acquisition hardware, electrode/optode placement, units, sampling and clock accuracy, preprocessing, detector/decomposition method, population, task, and outcomes for the intended study. Preserve raw data and an auditable exclusion log. Use deidentified local files only; do not place PHI in prompts, logs, examples, or bundled fixtures.

Reproducible installation

uv pip install "neurokit2==0.2.13"

For optional features, create a uv project, add only the packages actually required at reviewed exact versions, and commit/review the resulting uv.lock before uv sync --locked. NeuroKit2 exposes an upstream full extra, but this skill intentionally does not install that floating transitive set in an automated workflow. Optional capabilities can require MNE, cvxopt, Plotly, PyEMD, pyRQA, Pillow, OpenCV, or file readers. Record the resolved environment with the analysis. Provision any MNE data/template download as an explicit, checksummed study input. Do not install a moving development branch for a reproducible study.

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.

neurokit2 is a skill published in the GitHub repository K-Dense-AI/scientific-agent-skills (44,469 stars, last pushed today), licensed MIT. It adds 63 tokens to every session and 3,503 once invoked, about $0.0003 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 2026-09-03.
