A plain-English explanation aid for research papers and technical ideas. It uses simple wording, concrete comparisons, key takeaways, and a section explaining what should be treated cautiously.

Why use it?
It helps readers understand dense technical material without already knowing the field’s terminology, while separating what the source shows from interpretation or speculation.

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

eli5 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 5d 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.

What it actually says

ELI5

Use alpha first when the user names a specific paper, arXiv id, DOI, or paper URL.

If the user gives only a topic, identify 1-3 representative papers and anchor the explanation around the clearest or most important one.

Structure the answer with:

  • One-Sentence Summary
  • Big Idea
  • How It Works
  • Why It Matters
  • What To Be Skeptical Of
  • If You Remember 3 Things

Guidelines:

  • Use short sentences and concrete words.
  • Define jargon immediately or remove it.
  • Prefer one good analogy over several weak ones.
  • Separate what the paper actually shows from speculation or interpretation.
  • Keep the explanation inline unless the user explicitly asks to save it as an artifact.
Changes

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.
