The canvas ships 16 core node types and 8 BH-OS rail node types. Each runner extends BaseNodeRunner and is registered with the WorkflowExecutor.
Core nodes (3)
| Type | Runner | Purpose |
|---|
start | StartNodeRunner | Workflow entry. Defines input variables. |
end | EndNodeRunner | Workflow exit. Marks execution complete with output values. |
note | (annotation only) | Documentation node — no runtime effect. |
Logic & control (5)
| Type | Runner | Outputs |
|---|
condition | ConditionNodeRunner | true / false (field + operator + value) |
transform | TransformNodeRunner | default (Handlebars / Liquid template) |
classify | ClassifyNodeRunner | Dynamic — one per declared category |
wait | WaitNodeRunner | default (after delay or cron) |
user-approval | UserApprovalRunner | approved / rejected — pauses execution and writes to workflow_approvals |
Healthcare agents (4)
| Type | Runner | Outputs |
|---|
intake-agent | IntakeAgentRunner | success / escalate / error — orchestrates Vapi + intake state machine |
scribe-agent | ScribeAgentRunner | success / error — drafts SOAP notes |
therapy-agent | TherapyAgentRunner | success / concern / error — behavioral health analysis |
triage-agent | TriageAgentRunner | urgent / routine / self_care — ESI-aligned routing |
Integration & data (4)
| Type | Runner | Outputs |
|---|
guardrails | GuardrailsNodeRunner | pass / fail — HIPAA, 42 CFR Part 2, suicide-language, PII checks |
ehr-sync | EHRSyncNode | success / error — bidirectional FHIR sync against connected EHR |
fhir-query | FHIRQueryRunner | success / error — FHIR R4 search (Patient, Observation, Encounter, …) |
escalate | EscalateNodeRunner | (terminal) — sends notification via email / SMS / pager / Slack |
BH-OS rails (8)
The BH-OS rails are typed runners backed by StudioBlockRunner. Each rail wires the workflow into a corresponding backend service.
| Type | Service |
|---|
rails/assessment | Clinical assessment runner |
rails/triage | Triage runner |
rails/referral | Referral generator + closed-loop tracking |
rails/pa | Prior authorization workflow |
rails/mbc | Measurement-Based Care (PHQ-9 / GAD-7 cadence) |
rails/quality | HEDIS / MIPS measure capture |
rails/network | Provider network logic |
rails/pharmacy | Surescripts e-prescribing + interaction checks |
Validation
BaseNodeRunner.validate(node) enforces required fields per node type at design time. Connections are type-checked: a condition node’s true port can only connect to a node that accepts the condition’s state output shape.
