What is langcare-cardiovascular-risk?

A clinical calculator for estimating heart and blood-clot risks from FHIR medical records. FHIR is a standard format for exchanging healthcare data.

Use it to assess stroke risk in atrial fibrillation, bleeding risk, heart-attack risk in chest pain, or cardiovascular risk when considering statins.

It organizes patient conditions, measurements, and medicines into established risk scores that support treatment decisions.

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	$0.00088	$0.00927
Opus 5.5	$0.00035	$0.00371
Sonnet 5.5	$0.00018	$0.00185
Haiku 4.5	$0.00009	$0.00093

Security

Grade A, and why

langcare-cardiovascular-risk 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.

Cardiovascular Risk Assessment

When to Use This Skill

Use when a clinician needs cardiovascular risk stratification for treatment decisions including anticoagulation for AFib, statin therapy initiation, or acute chest pain evaluation.

Clinical Workflow

Use fhir_read to retrieve Patient demographics (age, gender, race for ASCVD PCE)
Use fhir_search to pull active Condition resources for scoring: AFib, CHF, HTN, DM, stroke/TIA, MI, PVD
Use fhir_search to pull Observation resources: BP, cholesterol, HDL, LDL, HbA1c, troponin, INR, creatinine
Use fhir_search to pull active MedicationRequest: anticoagulants, antiplatelets, statins, antihypertensives, NSAIDs
Select scores based on context: AFib -> CHA2DS2-VASc + HAS-BLED; chest pain -> HEART Score; primary prevention -> ASCVD PCE
Calculate scores using reference tables (see references/ascvd-heart-scoring.md)
Use fhir_create to create RiskAssessment resource with findings and predictions
Present scores with treatment-threshold recommendations per ACC/AHA guidelines

FHIR Resources

Patient -- Age, gender, race (US Core extension for ASCVD PCE)
Condition -- CHF, HTN, DM, stroke/TIA, MI, AFib, PVD, CKD
Observation -- BP (85354-9), cholesterol (2093-3), HDL (2085-9), LDL (18262-6), troponin (6598-7, 89579-7), INR (6301-6)
MedicationRequest -- Anticoagulants, antiplatelets, statins, antihypertensives
RiskAssessment -- Output: risk scores and predictions

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.
