spedas-skills-index

spedas-skills-index is a skill for Claude Code, Codex from spedas/spedas_agent_kit. It costs 57 tokens per session (2,417 once invoked), scanned A, original, MIT.

A directory for choosing the right SPEDAS workflow for heliophysics tasks. SPEDAS is a toolkit for loading and analyzing space-science measurements.

In plain words
What is it for?
Use it to route requests involving spacecraft data, published-paper reproduction, geometry, spectra, field models, or particle measurements.
Why use it?
It replaces memorizing many low-level tools with a small set of task-based choices and a clear first 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

spedas-skills-index 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 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.

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.

The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SPEDAS skills index

The spedas MCP server advertises many tools, but you should not learn them all. The agent-facing surface is: a small unified vocabulary + these skills. Pick the skill matching the intent, load it, follow it. Call spedas_overview() if unsure what exists; treat the full tool list as discoverable on demand, not memorized.

The unified vocabulary (what skills compose)

  • Plan: search_spedas_data_sources, plan_spedas_observation, compare_cdaweb_pds_spice, create_spedas_analysis_bundle
  • Data (one set of verbs, switch by source_type=cdaweb|pds|spice): browse_data_sources, load_data_source, browse_data_parameters, fetch_data_product, manage_data_cache
  • Geometry: get_ephemeris, compute_distance, transform_coordinates
  • Analysis ([analysis] extra): coordinate transforms, spectra, field models, particle moments, render_tplot

Low-level / source-specific compat tools exist for maintenance only — skills do not use them.

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.

spedas-skills-index 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 2,417 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.
