erg-arase-radiation-belt-waves

erg-arase-radiation-belt-waves is a skill for Claude Code, Codex from spedas/spedas_agent_kit. It costs 146 tokens per session (2,747 once invoked), scanned A, original, MIT.

A route guide for researchers working with ERG/Arase satellite and ground-based space-weather data, including radiation-belt particles, plasma waves, magnetometers, and aurora images.

In plain words
What is it for?
Use it to find data for studies of chorus, EMIC, and other waves, radiation-belt particle flux, satellite orbits, pulsating aurora, and measurements from related ground stations.
Why use it?
It helps locate the right datasets and first analysis output without pretending to be a new scientific analysis method.

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

erg-arase-radiation-belt-waves 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ERG/Arase radiation-belt, wave-particle, and ground-conjugate workflows

Use this skill when the science request mentions ERG, Arase, PWE/OFA/HFA, MGF, MEP-e/HEP/XEP/LEP, chorus/EMIC/hiss/whistler waves, radiation-belt electron flux, pulsating aurora, ISEE/MAGDAS/STEL ground magnetometers, OMTI all-sky imagers, VLF, or ground-conjugate context.

This is a route-scout skill, not a new analysis implementation. It tells an agent where the data usually lives, what the first artifact should be, and where the paper-quality boundary is. Keep all outputs artifact-first: write run metadata, provenance, variable lists, plots, and any diagnostics to the output directory; return only compact paths and caveats.

Route map

MCP/default-surface boundary

Read the table MCP-first. When a row lists a CDAWeb dataset, use the Agent Kit MCP unified data tools (browse_data_sources, load_data_source, browse_data_parameters, fetch_data_product) against that dataset before falling back to local Python. The pyspedas.erg.* names are external runtime routes, not Agent Kit MCP tools (external_runtime_route.not_an_mcp_tool: true). Ground-conjugate rows without a packaged CDAWeb dataset are PySPEDAS-only: an MCP-only client should preserve them as caveats/next-step routes and should not invent dataset IDs or MCP tool names.

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.

erg-arase-radiation-belt-waves is a skill published in the GitHub repository spedas/spedas_agent_kit (3 stars, last pushed 1mo ago), licensed MIT. It adds 146 tokens to every session and 2,747 once invoked, about $0.0007 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 2026-08-31.
