jupyter-live-kernel

jupyter-live-kernel is a skill for Claude Code, Codex from NeoLabs-Systems/NeoAgent. It costs 76 tokens per session (1,430 once invoked), scanned A, original, AGPL-3.0.

A live Jupyter notebook kernel for running Python code while keeping variables and results in memory between commands.

In plain words
What is it for?
Use it for interactive data analysis, machine-learning experiments, API exploration, and checking intermediate results as you build code.
Why use it?
It avoids restarting Python or rebuilding setup after every small change, which helps when exploring data, testing APIs, or developing code step by step.

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

jupyter-live-kernel scanned grade A with 1 finding 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 10d 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.

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.
