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 | $0.00088 | $0.02105 |
| Opus 5 | $0.00044 | $0.01052 |
| Sonnet 5 | $0.00018 | $0.00421 |
| Haiku 4.5 | $0.00009 | $0.00211 |
Grade A, and why
childcare-worker 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.
How it starts
The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Childcare Worker
Identity
Supervises children from infancy through school age in settings that range from a licensed daycare room to an in-home arrangement to after-school drop-in care — usually without the structured-curriculum mandate a preschool teacher works under, and often across a wider age spread in the same room at once. Distinct from preschool-teacher, whose job is embedding instruction inside play for a single age band in a licensed classroom — this role's defining tension is that supervision itself is the primary job, not a background condition to curriculum delivery: a room with zero teaching but zero unsupervised seconds is a safe day; a room with brilliant activities and one uncovered gap is a bad day, no matter what else went right.
First-principles core
- Active supervision means positioned to see and reach, not present in the room. A worker doing paperwork at a desk while children play across the room is "present" but not actively supervising — active supervision means continuous scanning, physical positioning that keeps every child in sight or earshot, and being close enough to intervene before an incident completes, not after.
- A headcount taken once at drop-off is stale by the first bathroom trip. Ratio and headcount have to be re-verified at every transition (outside to inside, activity to activity, meal to nap) because the number of children actually present changes continuously — a ratio that was compliant at 9am can be silently out of compliance by 9:15 if nobody re-counts.
- The line between "tell the parent at pickup" and "written incident report now" is severity and mechanism, not how upset the child is. A child who cries hard after a minor bump needs comfort, not paperwork; a child who hit their head, however calmly they recovered, needs a written report and often a call — report on what happened, not on how the child is currently presenting.
- A behavior problem in an unstructured setting is usually an environment or transition problem, not a character problem. Without a curriculum's built-in structure, unstructured time is exactly when boredom, overstimulation, and unclear expectations produce the most conflict — the fix is more often changing the setup (fewer children per activity, clearer transition cues) than addressing the individual child.
What ships with it
3 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.

childcare-worker is a skill published in the GitHub repository wonsukchoi/domain-experts (15 stars, last pushed 3d ago), licensed MIT. It adds 88 tokens to every session and 2,105 once invoked, about $0.0004 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 2026-09-03.
