What is prenatal-visit-workflow?

A structured clinical workflow for reviewing pregnancy visits by trimester and weeks of pregnancy, using ACOG guidance. ACOG is the American College of Obstetricians and Gynecologists.

Use it to review prenatal visits, blood pressure, weight gain, fetal measurements, glucose testing, preeclampsia risks, preterm-labor risks, and pending milestones.

It organizes maternal measurements, fetal findings, tests, and screening results so missed risks or upcoming care are easier to spot.

Token cost

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	$0.00110	$0.03958
Opus 5.5	$0.00044	$0.01583

Security

Grade A, and why

prenatal-visit-workflow 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 2mo 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.

Prenatal Visit Workflow

Overview

Pull and organize prenatal clinical data by trimester and gestational age following ACOG prenatal visit schedule. Retrieve pregnancy-related Conditions, maternal vital signs, fetal Observations, laboratory results, and screening outcomes. Track weight gain trajectory, blood pressure trends, and glucose screening results. Flag preeclampsia risk factors, gestational diabetes indicators, preterm labor risk, and deviations from expected visit schedule. Present a structured visit summary with outstanding orders and upcoming milestones.

FHIR Resources Used

Resource	Purpose	Key Fields
Patient	Maternal demographics, age, gravidity	birthDate, gender, identifier
Condition	Pregnancy diagnosis, complications	code, clinicalStatus, onsetDateTime, category
Observation	Vitals, fundal height, FHR, weight, urine, labs	code, valueQuantity, effectiveDateTime, component, interpretation

Procedure	Ultrasounds, amniocentesis, cervical cerclage	code, performedDateTime, status
DiagnosticReport	Ultrasound reports, lab panels	code, result, effectiveDateTime

Instructions

Step 1: Retrieve Patient Demographics

Tool: fhir_read
resourceType: "Patient"
id: "[patient-id]"

Extract birthDate (calculate maternal age -- flag if >=35 for advanced maternal age), gender (confirm female).

Step 2: Pull Pregnancy Condition

Tool: fhir_search
resourceType: "Condition"
queryParams: "patient=[patient-id]&code=77386006&clinical-status=active"

SNOMED 77386006 = Pregnancy (finding). If not found, try:

SNOMED 72892002 = Normal pregnancy
ICD-10 Z34 (Encounter for supervision of normal pregnancy)
ICD-10 O09 (Supervision of high-risk pregnancy)

Extract onsetDateTime to determine estimated gestational age (EGA). If EGA is not derivable from onset, search for EDD Observation (LOINC 11778-8 = Delivery date estimated).

What ships with it

2 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.

Changes

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.
