Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.00435 |
| Opus 5 | $0.00029 | $0.00217 |
| Sonnet 5 | $0.00012 | $0.00087 |
| Haiku 4.5 | $0.00006 | $0.00044 |
Grade B, and why
eli-quiz scanned grade B with 1 finding 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 9d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

ELI5 Quiz — Check Your Understanding
Test whether the last explanation landed. Ask questions at the current eli5 level.
Steps
-
Check current level:
cat .claude/eli5-state.json 2>/dev/null || echo "none"If no level found, default to eli5.
-
Identify the most recent concept explained in eli5 mode from the conversation.
-
Write 2–3 questions calibrated to the current level:
eli5 / eli-kid: Fill-in-the-blank or "what is this like?" questions. Example: "A database is like a giant ___. What goes in the blanks?"
eli-teen: "Real-world scenario" questions. Example: "If OAuth is a backstage wristband, what happens when it expires?"
eli-adult / eli-expert: "Apply it" questions. Example: "Your team is hitting slow API responses. Which analogy from today would you use to explain caching to your manager?"
-
Ask ONE question at a time. Wait for the answer before giving the next.
-
For each answer, give feedback in the current eli5 level's style:
- Correct: celebrate briefly in level-appropriate language, explain WHY it's right
- Wrong / partial: don't say wrong — say "Almost!" and give a gentle redirect using a new analogy angle
-
After all questions, give a brief summary: "You got [N/3]. [level-appropriate encouragement]."
Important
Stay in eli5 mode throughout the quiz. Questions, hints, and feedback all follow
the current level's rules from ~/.claude/skills/eli5-mode/references/core-rules.md.
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.

eli-quiz is a skill published in the GitHub repository kavyabhand/claude-eli5 (21 stars, last pushed 4mo ago), licensed MIT. It adds 58 tokens to every session and 435 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories).
