- 80% of tool parameters carry a description.Partial
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
create_patient_stream ~347
Create a Signal cued stream for one patient and get the first cue back synchronously. Every cue is federally-sourced, audience-safety-checked, and sequenced on the patient's prior response — so your agent never fabricates health content. Choose a template_id from the signal://catalog resource and pre-satisfy its required audience_tags + patient_context (clinical templates 422 without them). Display mode renders in your app: no PHI, no BAA. Each later cue MUST submit the prior message's feedback — the engine refuses to advance without it (the sequencing moat).
| Name | Type | Req | Description |
|---|---|---|---|
| attributes | object | – | De-identified patient context. v1 accepts free-form jsonb; future templates will enforce schemas. |
| audience_tags | array | – | Subset of the 14-tag B5/B6 schema. See list_sandbox_topics for sample topic labels. |
| delivery_mode | string | – | v1 is Display-only; Deliver-mode unlocks at Per-Episode tier after BAA. |
| feedback_timeout_days | integer | – | – |
| idempotency_key | string | – | Optional. Stripe-style create idempotency: a retried create with the same key returns the ORIGINAL stream instead of minting (and billing) a second one. Forwarded as the Idempotency-Key request heade… |
| template_id | string | yes | One of the live Signal templates. Read the signal://catalog resource for each template's required audience_tags + patient_context. On a production key a clinical template 422s if its required tags/co… |
| Name | Type | Req | Description |
|---|---|---|---|
| _meta | object | yes | Legal/disclosure block returned on every 2xx (A1 §6.7). |
| first_cue | object | yes | A cued message plus its per-cue receptivity score and audience-safety verdict. |
| next_cue_eligible_at | string|null | – | – |
| rate_limit | object | – | Discovery monthly cue-cap headroom. Absent on non-Discovery tiers (no cap). |
| state | string | yes | – |
| stream_id | integer | yes | Persist this — every later cue/read references it. |
No examples provided.
get_next_cued_message ~136
Submit the patient's response to the prior cue and get the next one — federally-sourced, audience-safety-checked, and re-sequenced on that feedback. REFUSES WITHOUT PRIOR-MESSAGE FEEDBACK (the moat): the engine will not advance a stream blind, returning 409 if you skip it. response_action is one of the accepted cue vocabulary (see the signal://catalog resource). Same idempotency_key + same feedback returns the cached cue; conflicting feedback under the same key returns 409.
| Name | Type | Req | Description |
|---|---|---|---|
| feedback | object | yes | – |
| stream_id | integer | yes | The stream_id returned by create_patient_stream. |
| Name | Type | Req | Description |
|---|---|---|---|
| _meta | object | yes | Legal/disclosure block returned on every 2xx (A1 §6.7). |
| idempotent | boolean | – | true when this is the cached result of a repeated idempotency_key. |
| message | string | – | – |
| next_cue | object | – | A cued message plus its per-cue receptivity score and audience-safety verdict. |
| normalized_action | string|null | – | null when the submitted response_action was a recognized value; otherwise the acknowledge-class value the well-formed-but-unrecognized action was folded to (forward-compat tolerance). Always present… |
| rate_limit | object | – | Discovery monthly cue-cap headroom. Absent on non-Discovery tiers (no cap). |
| sandbox_exhausted | boolean | – | Present + true when the sandbox subset is exhausted; no next_cue then. |
| state | string | yes | – |
| stream_id | integer | yes | – |
No examples provided.
list_sandbox_topics ~75
List the curated sandbox topic labels that define the free Discovery corpus — every topic federally-sourced and audience-safety-checked. Use it to preview what content domains exist before creating a stream. Does NOT enumerate messages — the corpus stays internal. For the full live template catalog + gating contract, read the signal://catalog resource.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| _meta | object | yes | Legal/disclosure block returned on every 2xx (A1 §6.7). |
| template_id_for_sandbox | string | – | – |
| topic_labels | array | yes | – |
No examples provided.
lookup_health_fact ~157
Zero setup — NO key required. Returns ONE already-public federal health fact, list, or tip for a question or topic (e.g. "high blood pressure", "sleep", "type 2 diabetes"), with its federal source (CDC / MedlinePlus / NIH) and a link to the public uphealth.me page. Free + rate-limited. For adaptive, patient-specific message sequencing — receptivity-scored cues + audience-safety verdicts over the full library of federally-sourced facts, lists & tips — get a free Discovery key at https://uphealth.us/signup
| Name | Type | Req | Description |
|---|---|---|---|
| q | string | yes | A health question or topic, e.g. "high blood pressure", "sleep", or "type 2 diabetes". |
| Name | Type | Req | Description |
|---|---|---|---|
| attribution | string | yes | "Source: <agency> via Uphealth". |
| disclaimer | string | yes | – |
| fact | object | yes | The single already-public federal message — a fact, list, or tip (see kind). |
| topic | string | – | The matched topic's title. |
| upgrade | object | yes | The free-key upsell — adaptive sequencing lives behind a Discovery key. |
No examples provided.
read_stream_state ~79
Read a stream's current state, its current cued message, and event count. Read-only — does NOT advance the stream or consume a cue. Use it between feedback turns to inspect where a patient is in their federally-sourced, audience-safety-checked sequence.
| Name | Type | Req | Description |
|---|---|---|---|
| stream_id | integer | yes | The stream_id returned by create_patient_stream. |
| Name | Type | Req | Description |
|---|---|---|---|
| _meta | object | yes | Legal/disclosure block returned on every 2xx (A1 §6.7). |
| current_cue | object|null | – | – |
| events_count | integer | – | – |
| next_cue_eligible | boolean | – | – |
