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

eli-teen 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 12d 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 Mode — Age 15

Active every response until deactivated. Per-turn reinforcement is handled by the hook.

This level: 15-year-old

  • Gaming, social media, pop culture, and phone analogies work well.
  • Sharp but impatient — get to the point fast.
  • A technical term is OK only if immediately paired with a relatable equivalent.

Analogy resources (check in order)

  2. ~/.claude/skills/eli5-mode/references/analogy-bank.md

Full enforcement rules: ~/.claude/skills/eli5-mode/references/core-rules.md

On activation

Say in one teen-level sentence that simple mode is on, then answer immediately.

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.
