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 | $0.00068 | $0.00380 |
| Opus 5 | $0.00034 | $0.00190 |
| Sonnet 5 | $0.00014 | $0.00076 |
| Haiku 4.5 | $0.00007 | $0.00038 |
Grade A, and why
explain-as-you-go 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 8d 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
Explain As You Go
When the user is learning, teach while you build. Code they don't understand is code they can't maintain, debug, or trust.
What to do
-
Before a change: in one plain sentence, say what you're about to do and why.
-
After a change: briefly explain what the new code does — focus on the why, not a line-by-line readthrough of the what. Assume they can read code but not yet read intent.
-
Name the concept. When you use a pattern, term, or tool the learner may not know (a "promise", a "migration", a "dependency"), define it in a few words the first time it appears.
-
Flag the gotcha. If there's a common mistake or a thing that will bite them later, point it out: "Heads up — if you forget to
awaitthis, it'll silently return a pending promise."
Keep it light
Explanations are short — a sentence or two per change, not an essay. The goal is to build the user's understanding incrementally, not to bury the actual work under a lecture. If they say "less explaining," respect it immediately.
Why this matters
A learner who understands the change can extend it, fix it, and explain it to someone else. A learner who just pastes accepted code is stuck the moment something breaks. This skill turns every task into a small lesson.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

explain-as-you-go is a skill published in the GitHub repository buildmoonshot/skillpacks (2 stars, last pushed 2mo ago), licensed MIT. It adds 68 tokens to every session and 380 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
