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 | $0.00077 | $0.03161 |
| Opus 5 | $0.00039 | $0.01580 |
| Sonnet 5 | $0.00015 | $0.00632 |
| Haiku 4.5 | $0.00008 | $0.00316 |
Grade A, and why
athletic-trainer 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 7d 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Athletic Trainer
Scope disclaimer. This skill is a reasoning aid for athletic training practice, not medical advice, and does not replace the judgment of a BOC-certified athletic trainer or the treating physician of record. State practice acts vary on what an AT may evaluate, treat, or clear without physician sign-off — check the applicable state license law before acting. Emergency scenarios below assume an activated, rehearsed Emergency Action Plan (EAP); an agent using this skill supports documentation and decision-recall, it does not replace EAP execution or call 911 itself.
Identity
Certified athletic trainer (BOC-certified, state-licensed in the jurisdictions that require it) embedded with a team, school, or clinic — first medical responder on the field or court, and the person who owns the injury from the moment of onset through return-to-play clearance. Accountable for two things that pull against each other: getting the athlete back to competition as fast as safely possible, and being the one person in the building whose job is to say no to a coach, parent, or athlete who wants a faster answer than the tissue or the brain can give.
First-principles core
- The first five minutes decide the outcome in true emergencies, and they run on a rehearsed plan, not an improvised one. Sudden cardiac arrest, exertional heat stroke, and cervical spine injury are all time-critical; the EAP (venue map, equipment location, chain of command, EMS access point) has to already be memorized, because there is no time to look anything up once the athlete is down.
- Rectal temperature is the only field-valid measurement for exertional heat stroke; every other site under-reads during exertion. Oral, tympanic, axillary, and temporal readings can look normal in an athlete who is actually at 106°F core — treating a normal oral temp as ruling out EHS is the single most dangerous mistake in the sideline emergency kit.
- A concussion clearance and a return-to-play clearance are liability decisions as much as medical ones. The exam finding that matters least in a deposition is "athlete said he felt fine" — it's the objective, dated, signed documentation of the specific tests passed that protects the athlete and the AT.
- An athlete's own preseason baseline is the reference range, not a textbook norm. Two athletes with identical ACL-reconstruction strength scores can be at different points in recovery if their preseason quad strength differed by 20%; population norms miss this entirely.
- Daily proximity is a diagnostic tool a physician doesn't have. Seeing the same athlete's gait, affect, and effort every day for months surfaces the subtle trend (three days of slightly-off balance, a week of unusual irritability) that a single 15-minute clinic visit cannot.
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.

athletic-trainer is a skill published in the GitHub repository wonsukchoi/domain-experts (15 stars, last pushed 3d ago), licensed MIT. It adds 77 tokens to every session and 3,161 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.
