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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 54 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00196 | $0.02361 |
| Opus 5 | $0.00098 | $0.01180 |
| Sonnet 5 | $0.00039 | $0.00472 |
| Haiku 4.5 | $0.00020 | $0.00236 |
Grade A, and why
magazine-explainer 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.
How it starts
The opening of the file, as written. The whole thing — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Magazine-style explainer builder
Turn a topic (or an existing chat / article) into a print-ready PDF explainer that looks like a real kids' magazine feature and reads like a sharp human wrote it for one specific kid. The visual system is proven and bundled; your job is good research, a strong narrative, real photos, and clean prose.
What makes these good
- One kid, one obsession. Written for a named child at their level, around a single subject. Voice is warm and direct, never dumbed-down.
- Magazine layout, not a worksheet. A dramatic cover, numbered sections with verb-led titles, cards, comparison tables, "how it works" diagrams, real photographs.
- Teaches real ideas. Introduce true terminology and define it once (the way a good guide teaches "brushless motor" instead of hiding it). Kids rise to it.
- Audited prose. No AI slop. Every draft passes the PROSE.md + stop-slop check before render.
Workflow
1. Scope it (ask only what you can't infer)
Settle: the subject, the kid's name and age (drives reading level), the angle (what about the subject — "how X works", "how to get into X", "the wildest X"), and the accent color theme. If a source already exists in the conversation (a chat, an article, notes), build from it. Pick sensible defaults and state them rather than stalling — Tim prefers action over questions.
2. Research
Gather real, correct material — don't wing facts for a kid.
- Use WebSearch / WebFetch for facts, and the browser (Chrome MCP) when a page is JS-gated.
- Find real photos: image-search for clean, white-background subject shots, then download
them with
scripts/fetch_image.sh <url> img/<name>.jpg. Read each downloaded image to confirm it's the right subject and not a logo, 404, or watermark. Save 2–4 good ones into animg/folder next to where the HTML will live. - Plan a mix of photos and diagrams. Photos show what things look like; a custom diagram shows
what a photo can't — a labeled cutaway, a to-scale comparison, a process or anatomy. The best
issues alternate them. Note which sections want a photo and which want a hand-built SVG diagram
(see
references/design-system.md→ "Photos vs. diagrams" and "Diagrams"). - Note source quality; flag anything you're unsure of so it can be checked, and keep a light honest disclaimer in the footnote if facts/prices may drift.

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.

magazine-explainer is a skill published in the GitHub repository hugobowne/show-us-your-agent-skills (67 stars, last pushed 1mo ago), licensed MIT. It adds 196 tokens to every session and 2,361 once invoked, about $0.0010 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 2026-08-30.
