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 | $0.00038 | $0.00134 |
| Opus 5 | $0.00019 | $0.00067 |
| Sonnet 5 | $0.00008 | $0.00027 |
| Haiku 4.5 | $0.00004 | $0.00013 |
Grade A, and why
explaining-code 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 2d 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.
This is a copy
95% identical to explain-code — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
When explaining code, always include:
- Start with an analogy: Compare the code to something from everyday life
- Draw a diagram: Use ASCII art to show the flow, structure, or relationships
- Walk through the code: Explain step-by-step what happens
- Highlight a gotcha: What's a common mistake or misconception?
Keep explanations conversational. For complex concepts, use multiple analogies.
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.

explaining-code is a skill published in the GitHub repository vigo/claude-skills (4 stars, last pushed 3mo ago), licensed MIT. It adds 38 tokens to every session and 134 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to explain-code, differing in 2 lines, and is treated as a copy.
