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 | $0.00226 | $0.02927 |
| Opus 5 | $0.00113 | $0.01463 |
| Sonnet 5 | $0.00045 | $0.00585 |
| Haiku 4.5 | $0.00023 | $0.00293 |
Grade A, and why
arts-crafts 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 — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.
arts-crafts
Turn "what can we make today?" into a ready-to-run craft plan. Given a theme or occasion, produce a complete project plan — supplies, steps, safety, mess, prep, cleanup — calibrated to the age of the child or class. Default audience K-5 (ages 5-10); PreK (2-4) supported explicitly. A non-crafty adult can run it without further prep.
When to trigger
Use this skill whenever a user asks for a craft, project, or "make something" idea for a child or classroom. Teachers and parents phrase it many ways — trust the description keywords rather than a strict format. If the only thing missing is the age band, ask one clarifying question. Otherwise proceed with defaults.
Inputs
Parse these from the user's request:
- Theme / occasion — holiday, season, book, unit topic, animal, concept. Required (if missing, suggest two and pick one).
- Age band —
2-4(PreK / toddler),5-7(K-2),8-10(3-5). Default5-7if unspecified. - Group size — single child, small group (2-6), classroom (15-30). Default single/small.
- Time budget — total minutes (prep + activity). Default 30 min activity.
- Available supplies — optional constraint ("only construction paper and glue", "no scissors", "recycled only").
- Mess tolerance —
low/medium/high. Defaultmedium. - Setting — home vs. classroom. Default home unless phrasing implies classroom.
Inferring age from phrasing (check before asking)
| Phrase in the request | Age band |
|---|---|
| "pre-k", "preschool", "toddler", "2-year-old", "3-year-old", "4-year-old", "daycare" | 2-4 |
| "kindergarten", "kinder", "TK", "5-year-old", "1st grade", "2nd grade", "6-year-old", "7-year-old" | 5-7 |
| "3rd grade", "4th grade", "5th grade", "8-year-old", "9-year-old", "10-year-old", "elementary" | 8-10 |
| "my kid", "my class", "elementary classroom", no age cue | default 5-7 |
| Spans ages (e.g. "my kids ages 3 and 7") | anchor on younger; add older-sibling variation |
If age is truly unclear and you can't infer, ask ONE question:
What ships with it
5 files 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.
