paper-reproduction

paper-reproduction is a skill for Claude Code, Codex from spedas/spedas_agent_kit. It costs 42 tokens per session (1,507 once invoked), scanned A, original, MIT.

A guided attempt to reproduce a published heliophysics research paper, figure, or event list using SPEDAS Agent Kit, a toolkit for analyzing space-physics data.

In plain words
What is it for?
Use it to collect the paper's inputs, create plots or derived tables, save provenance and reproducible scripts, and document caveats and feedback.
Why use it?
It turns a paper's evidence and assumptions into a narrow, traceable analysis while recording missing data or tool capabilities instead of overstating the result.

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

paper-reproduction 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.

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 — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Paper reproduction workflow

Use this skill when a researcher asks to reproduce, sanity-check, or extend a published paper, figure, event list, or DOI using SPEDAS / PySPEDAS / Agent Kit. The goal is not to claim a paper-quality reproduction on the first pass. The goal is to make a narrow, auditable researcher attempt that produces artifacts, records provenance, and turns every missing capability into concrete Agent Kit feedback.

Deliverables

Write an artifact bundle under an explicit output_dir containing at least:

  • REPORT.md — citation, science question, interval/product assumptions, reproduction status, caveats, and Agent Kit feedback.
  • artifacts/provenance.json — machine-readable run record using the schema below.
  • One or more plots or small derived tables. Prefer PNG/HTML/JSON artifacts over pasted arrays or CDF contents.
  • The script, notebook, or recipe that regenerated the artifacts.

Workflow

  1. Intake the paper evidence. Capture title, DOI, figure/table target, science question, mission(s), instrument(s), cadence, coordinate basis, and any exact interval from the paper or supplement. If the interval is inferred, label it as candidate_interval.
  2. Plan the data route before fetching. Choose source_type, dataset/product, parameters/variables, time range, cache/output directory, and expected artifact shape. Start with spedas_overview, search_spedas_data_sources, plan_spedas_observation, or create_spedas_analysis_bundle when the route is unclear. If you bypass Agent Kit and use PySPEDAS directly, state why.
  3. Fetch narrowly. Use the smallest interval and product set that can test the paper claim. Keep cache and output paths isolated per paper/iteration.
  4. Reproduce one minimum diagnostic. Make a researcher-useful first plot or derived quantity before attempting the full paper. Examples: overview time series, E + Ve×B / J·E' proxy, E_parallel proxy, PSD, pitch-angle distribution, or particle distribution slice. Label proxy diagnostics as proxy, not paper-quality.
  5. Validate visually and numerically. Check the artifact is non-empty, axes and units are labeled, spikes/features align with the target interval, and the provenance contains enough fields to rerun the attempt.
  6. Record Agent Kit feedback. For every paper, write one concrete gap or improvement. Batch repeated gaps across several papers before opening PRs; avoid one issue per paper unless the bug blocks progress.

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.

paper-reproduction is a skill published in the GitHub repository spedas/spedas_agent_kit (3 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 1,507 once invoked, about $0.0002 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.
