explain

explain is a skill for Claude Code, Codex from surfmind-space/awesome-surfmind. It costs 83 tokens per session (810 once invoked), scanned A, original, MIT.

A plain-language explanation tool for selected or visible content. It defines unfamiliar terms, supplies needed background, and can research missing context when required.

In plain words
What is it for?
Use it to simplify technical or general content, explain jargon, provide an ELI5-style breakdown, and clarify what a page is saying.
Why use it?
It helps readers understand what content means without already knowing its jargon or subject area.

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

explain 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.

How it starts

The opening of the file, as written. The whole thing — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Explain

Explain the selected or visible content so the reader can understand it without prior expertise, accurately and evidence-backed. Never invent details or fill gaps with made-up facts.

  1. Base the explanation on the selected or visible page content. State the core idea in one or two plain sentences, define any jargon, and add the background that makes it make sense.
  2. If the page lacks the context needed to explain it well, gather more: use web search or any suitable MCP/tool available to research the topic, then explain from what you find.
  3. If web search is disabled and no suitable tool is available, explain what the content supports and clearly note what couldn't be verified.

Calibrate depth to how much the content actually holds, not to a fixed length. Look at how many distinct ideas the source contains and match the explanation to that:

  • A single self-contained term or one simple idea → keep it tight: the plain-language definition, the bit of background that makes it click, and one example or analogy. A few short paragraphs (or one flowing passage) is usually enough. Don't expand it into a multi-section reference — no heading-per-aspect, no exhaustive tables, no etymology or tangents the reader didn't ask for. One good example makes the point; don't enumerate every variant or related case (e.g. for a term illustrated by one HTTP method, don't catalogue all of them).
  • A dense, layered, or multi-part source (a code snippet with several moving parts, a formula and its implications, a passage stacking multiple concepts) → go fuller: lead with the core idea, then use sections, examples, and analogies to make each part genuinely clear.

Detailed, multi-section explanations are good when the material is genuinely that involved, and miscalibrated when it isn't — a long answer to a one-term question is a defect, not thoroughness. Compress to a sentence or two only when the user explicitly asks for a short, brief, or quick explanation (or a TL;DR). Whatever the length, keep the writing clear and easy to follow, and make every part earn its place: depth that aids understanding, never filler, padding, or restating the same point.

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.
