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 →
all_heaters_off All Heaters Off ~53
Turn every output off (heater range 0 on outputs 1-4), like the front-panel All Off key, and stop any running wait. Reports the read-back range of each output and `all_off`.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
get_command_log Get Command Log ~46
Return the most recent raw commands sent to / replies received from the instrument (newest last). Useful for debugging and for recording what was done.

|---|---|---|---|
| result | array | yes | – |

Structured output declared, but exposes no named fields.
No examples provided.
get_heater_status Get Heater Status ~68
Report each output's control mode and input, heater range, output %, setpoint (and in kelvin), ramp state, PID values and heater errors (open/short). Reading a heater error clears it on the controller.

set_heater_range Set Heater Range ~159
Set an output's heater range (each step is ~10x more power). Anything above 0 lets the output heat: in closed loop as the PID demands, in open loop at the front-panel manual output. Refused above `max_heater_range`, or if the setpoint already programmed on a closed-loop, zone or warm-up output is above `max_setpoint_k`. Start with the lowest range that can reach the setpoint.

set_ramp Set Ramp ~110
Turn setpoint ramping on or off for an output's control loop and set the rate. With ramping on, the next setpoint change moves the setpoint gradually - gentler on samples and wiring.
| Name | Type | Req | Description |

set_setpoint Set Setpoint ~100
Set the control setpoint of an output's loop in kelvin. If setpoint ramping is on, the setpoint moves toward the new value at the ramp rate. Heating only happens if the output is in closed-loop mode and its heater range is not off. Refused above `max_setpoint_k`.

wait_for_stable_temperature Wait For Stable Temperature ~146
Wait until the control input of `output` has stayed within `tolerance_k` of the setpoint (and the setpoint is no longer ramping) for `stable_for_s`, or until `timeout_s`. Returns whether it stabilised, the final temperature and a downsampled trace. Changes nothing.
