eli5

eli5 is a skill for Claude Code from quay/ai-helpers. It costs 68 tokens per session (433 once invoked), scanned A, original, MIT.

A simple-explanation skill for technical concepts, using plain language, a concrete analogy when useful, and a short code example. ELI5 means “explain like I'm five,” but this version is aimed at engineers who want a clear mental model without condescension.

In plain words
What is it for?
Use it when someone asks for an ELI5 explanation, a breakdown of a concept, or a concrete example of how something works.
Why use it?
It turns difficult or unfamiliar topics into a short explanation with an example that can be run or inspected. This helps readers understand how a concept works rather than only memorizing a definition.

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 1mo 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 — Explain Like I'm 5

Distill $ARGUMENTS into a short, clear explanation with a concrete code snippet or example. The audience is a senior engineer who wants the mental model, not a tutorial.

Format

Every response follows this structure:

1. One-liner (required)

One sentence: what it is, in plain terms.

2. Analogy (optional)

A one-sentence analogy only if it genuinely clarifies. Skip if forced.

3. Code snippet or concrete example (required)

A short, runnable snippet or real-world example that demonstrates the concept. Prefer examples in the current project's primary language and domain. Annotate with 1-2 inline comments only where non-obvious.

4. The gotcha (optional)

One sentence on the most common misconception or sharp edge, if one exists.

Rules

  • Keep the entire response under 15 lines of prose (code doesn't count toward this).
  • Never pad with disclaimers, caveats, or "it depends" hedging.
  • Never explain what the user already knows — skip straight to the part they're asking about.
  • If the question is about something in the current codebase, reference the actual code, not a hypothetical.
  • Match the user's depth: if they ask "how does SSA work in controller-runtime", assume they know what controllers are.

Depth escalation

If the user asks for more detail, add ONE level of depth — internal mechanics, edge cases, or a second code snippet. Don't repeat the original explanation.

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.
