Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

No change was recorded against any check on this day. Stability & Change Management went from 90 to 93. That category is still filling its 30-day observation window: 27 days of observed history at the previous scan, 28 at this one. The score rises as the window fills, whether or not the server changes.

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 →
get_current_glucose Current glucose ~102
Read the most recent glucose measurement from the FreeStyle sensor, with the instant it was actually measured. The value is the latest one upstream holds, not a live reading — always report `measured_at` rather than calling it 'now'. Informational only: this is not a medical device and must not be used for any treatment decision.
| Name | Type | Req | Description |
|---|---|---|---|
| unit | string | – | Unit for the returned values. Storage is always mg/dL; this only affects display. |
No output schema declared.
No examples provided.
get_glucose_history Glucose history and time in range ~189
Glucose readings over the last N hours (max 12), with time-in-range computed against the account's own target band. Upstream holds only about 12 hours of detailed data and ignores any longer request, so the response always states the range it actually covered and sets `truncated` when that is less than asked — report that range, never the one requested. Collection gaps are listed separately and are not interpolated across; a percentage over a series with gaps describes only the covered time. Informational only: not a medical device, and not a basis for any treatment decision. This is not an HbA1c or GMI estimate — those need weeks of data.
| Name | Type | Req | Description |
|---|---|---|---|
| hours | integer | – | Hours of history to cover, 1 to 12. |
| unit | string | – | Unit for the returned values. Storage is always mg/dL; this only affects display. |
No output schema declared.
No examples provided.
