eli5

eli5 is a skill for Claude Code from ManceRayder42/jarvis-os. It costs 52 tokens per session (283 once invoked), scanned A, original, MIT.

A method for explaining a technical idea with a simple, self-contained HTML page using large visuals and very little text. It is aimed at readers who have no prior knowledge of the subject.

In plain words
What is it for?
Use it to explain codebases, software architecture, or other concepts as a visual web page, especially when a diagram or sequence is useful.
Why use it?
It removes the need for beginners to understand specialist terms before seeing the main idea. Diagrams can show relationships and steps more clearly than a long explanation.

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 visual explainer

Anthropic internal pattern (Thariq, product lead, via @trq212). Source write-up: https://leslieli.dev/notes/anthropic-eli5-skill-html-artifacts/

Original prompt: "Explain like I'm someone who knows nothing about this topic, using an HTML artifact with big pictures and few words."

Steps

  1. Assume reader new to topic — no jargon without one-line definition.
  2. Load artifact-design skill before writing (mandatory in this environment for any HTML artifact).
  3. Build ONE self-contained HTML page: diagram or visual sequence first, minimal text. Add interactive control only when it reveals a state change or relationship — never as decoration.
  4. Label assumptions plainly. A simplified diagram is illustration, not proof.
  5. Publish via Artifact tool — title = topic name, favicon required.

Keep adaptation short. Source contributes the format constraint (big pictures, few words), not a house style or claim interaction always helps.

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.
