What is langcare-pediatric-growth?

A clinical assessment of a child's growth using weight, height or length, head circumference, and body-mass index against WHO and CDC growth charts. WHO covers children from birth to age two, while CDC charts cover ages two to twenty.

Use it to retrieve growth measurements and diagnoses, calculate percentiles and Z-scores, plot growth trajectories, and flag measurements that need attention.

It helps clinicians compare measurements over time and identify possible growth concerns such as poor growth or obesity.

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	$0.00081	$0.00798
Opus 5.5	$0.00032	$0.00319
Sonnet 5.5	$0.00016	$0.00160
Haiku 4.5	$0.00008	$0.00080

Security

Grade A, and why

langcare-pediatric-growth 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.

Pediatric Growth Assessment

When to Use This Skill

Use when a clinician needs to evaluate a pediatric patient's growth trajectory against age-appropriate percentile charts.

Clinical Workflow

Use fhir_read to retrieve Patient demographics (birthDate for age calculation, gender for sex-specific charts)
Use fhir_search to pull Observation resources for weight (LOINC 29463-7), length/height (LOINC 8302-2 height, 8306-3 body length), head circumference (LOINC 9843-4), and BMI (LOINC 39156-5) over time
Determine chart set: WHO (0-2 years), CDC (2-20 years) -- see references/who-cdc-percentiles.md
Plot current and historical measurements against sex-specific percentile curves
Calculate percentiles and Z-scores for current measurements
Identify growth concerns: weight-for-age <3rd percentile (failure to thrive), BMI >85th (overweight), BMI >95th (obese), crossing >2 major percentile lines (growth faltering or acceleration), head circumference <3rd or >97th
Use fhir_search to pull Condition resources for underlying diagnoses affecting growth
Present growth dashboard with current percentiles, trajectory, and flagged concerns

FHIR Resources

Patient -- Age and sex for chart selection
Observation -- Weight (29463-7), height (8302-2), length (8306-3), head circumference (9843-4), BMI (39156-5)
Condition -- Growth-related diagnoses (FTT, obesity, short stature, endocrine conditions)

FHIR Query Examples

Pull Growth Measurements

fhir_search(resourceType="Observation", queryParams="patient=[patient-id]&code=29463-7,8302-2,8306-3,9843-4,39156-5&_sort=date&_count=100")

Clinical Guidelines

WHO growth standards (0-2 years): international reference for breastfed infants
CDC growth charts (2-20 years): US reference population
AAP guidelines for failure to thrive evaluation
AAP Expert Committee recommendations for childhood obesity

Interpretation Guide

Use WHO charts for 0-2 years (based on breastfed infant norms), CDC charts for 2-20 years
Percentile thresholds: <3rd concerning for undernutrition, 3rd-85th normal, 85th-95th overweight, >95th obese
Track trajectory: crossing 2+ major percentile lines in either direction warrants evaluation
Head circumference: <3rd may indicate microcephaly, >97th may indicate macrocephaly or hydrocephalus (monitor closely in first 18 months)
For premature infants: use corrected gestational age until 24 months (corrected = chronological age minus weeks premature)
BMI interpretation for children: use BMI-for-age percentile, not adult BMI categories

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.
