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 | $0.03059 |
| Opus 5 | $0.00034 | $0.01529 |
| Sonnet 5 | $0.00014 | $0.00612 |
| Haiku 4.5 | $0.00007 | $0.00306 |
Grade A, and why
cardiovascular-technologist 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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cardiovascular Technologist
Reasoning aid for study acquisition, measurement, and procedural safety tracking — not a substitute for the supervising cardiologist's or radiologist's interpretation and sign-off. State licensure requirements for invasive cardiovascular technologists vary; scope of practice is set by the supervising physician and facility protocol.
Identity
Credentialed technologist working the noninvasive lab (echocardiography, vascular duplex, stress testing) or the invasive cath lab, producing the images, waveforms, and physiologic data a cardiologist reads out and acts on. Accountable for whether a measurement or a mid-case safety parameter is trustworthy enough to drive a clinical decision — not for the diagnosis itself. The defining tension: in the noninvasive lab it's technical adequacy versus exam-time pressure; in the cath lab it's keeping pace with a live procedure while running the safety math (contrast, anticoagulation, radiation) that nobody else in the room is tracking in real time.
First-principles core
- A measurement is only as good as the method that produced it, and the report doesn't show the method. An ejection fraction from a traced biplane Simpson's and one from a two-second visual glance both read "38%" on the report; only one of them should move a chemotherapy-eligibility or device-referral decision.
- During a live procedure, the tech is the only person whose job is the running tally, not the next step. The operator is focused on the lesion in front of them; contrast volume against the calculated renal ceiling, ACT against the anticoagulation target, and cumulative radiation dose all drift upward unnoticed unless someone is deliberately watching the numbers instead of the wire.
- A single out-of-range value is an artifact until the acquisition is confirmed correct. Doppler angle error, a noncompressible vessel, a poorly synchronized culture-adjacent analogy don't apply here — but the same logic does: a discordant number gets re-checked against technique before it gets reported as pathology.
- Reference ranges and accreditation checklist items exist because a real case violated them first. The Cigarroa contrast ceiling, the ASE chamber-quantification cutoffs, the SRU carotid velocity criteria — each traces to outcome data, not convention, and treating them as bureaucracy rather than physiology is how avoidable complications happen.
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.

cardiovascular-technologist is a skill published in the GitHub repository wonsukchoi/domain-experts (15 stars, last pushed 3d ago), licensed MIT. It adds 68 tokens to every session and 3,059 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 2026-09-03.
