psp-solar-wind-switchbacks

psp-solar-wind-switchbacks is a skill for Claude Code, Codex from spedas/spedas_agent_kit. It costs 57 tokens per session (2,630 once invoked), scanned A, original, MIT.

A research workflow for analysing solar wind and magnetic-field changes measured by NASA’s Parker Solar Probe near the Sun. It focuses on switchbacks, which are sudden changes in the direction of the solar wind’s magnetic field.

In plain words
What is it for?
Use it to select FIELDS and SWEAP data, align measurement timing, inspect magnetic-field and velocity changes, and produce traceable analysis files.
Why use it?
It turns a paper or event question into a defined data plan and labels measurements that may only be indirect evidence.

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

psp-solar-wind-switchbacks 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 8d 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.

PSP solar wind and switchback workflow

Use this skill for Parker Solar Probe (PSP) near-Sun solar-wind papers or event requests involving Encounter 1, switchbacks, structured slow wind, Alfvénic velocity spikes, or magnetic-field rotations. It turns a paper/event prompt into a narrow FIELDS + SWEAP data plan, an artifact bundle, and explicit proxy labels.

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.

psp-solar-wind-switchbacks is a skill published in the GitHub repository spedas/spedas_agent_kit (3 stars, last pushed 1mo ago), licensed MIT. It adds 57 tokens to every session and 2,630 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 2026-08-31.
