Purpose and description
Enable an AI agent to recognise a kettle, assess its readiness to heat and pour water, and determine which operations its design and observed condition permit.
A kettle is a vessel designed primarily to heat water to boiling, typically with a lid, handle and pouring spout, using either an external heat source or an integrated electric heating element.
It can be Classify the kettle's heating configuration and match it to documented compatible equipment.; Check water level, assembly and visible condition before authorising heating.; Select an available temperature or heating mode and interpret its completion indication.; Determine whether the current state permits lifting, pouring, refilling or cleaning.; Identify a need for descaling, filter cleaning, repair assessment or withdrawal from use..
Distinguishing features
Its primary intended task is heating water for transfer to another vessel, rather than cooking food in place.
Its vessel has a handle and a pouring outlet intended to transfer heated water by tilting the vessel.
An electric heating element is optional: an externally heated kettle remains within scope.
A lid, whistle, detachable base or automatic shutoff identifies a configuration but is not required to recognise every kettle.
A vessel primarily intended to steep and serve tea is a teapot; direct water-heating capability and declared intended use must resolve ambiguous combined designs.

Kettle identity and boundary Recognises the water-heating and pouring vessel while separating kettle variants from neighbouring appliance kinds.
The name alone does not distinguish a kettle from a teapot, cooking pot or hot-water dispenser.
Intended water task
Establishes what the vessel is designed to heat and how the heated water is used.
Primary heating purpose
Record evidence that the vessel is primarily intended to heat water for pouring, including any explicitly permitted additional uses.
- What declared purpose and physical features establish this vessel as a kettle? definition
- Does brewing, cooking or dispensing define its primary function strongly enough to place it in a neighbouring model? boundary
Heating variant
Separates electric and externally heated configurations without splitting the registry kind.
Vessel and heat interface
Record how heat reaches the water and which attached or separate components constitute the working kettle assembly.
- Is heat supplied through an integrated electric element, an external cooking surface or another documented arrangement? definition
- Which base, connector, lid or other components belong to the kettle assembly, and which belong to its supporting equipment? boundary
Water containment and pouring Captures usable fill limits and the physical path from filling through heated-water transfer.
A kettle must retain water during heating and permit controlled pouring without confusing nominal capacity with a safe operating fill.
Fill envelope
Relates observed water quantity to the kettle's documented operating limits.
Permitted water charge
Record fill limits, their evidence and the means available to observe the current quantity.
- What minimum, if any, and maximum operating fill are specified in mL or L, and where are they marked or documented? measurement
- Can the current fill be verified before heating, and what action is required if it cannot? action
Pouring path
Examines the lid, outlet, handle and any filter as a hot-water transfer system.
Controlled water transfer
Record the required pouring configuration and observed defects that could disrupt retention, grip or flow.
- How must the lid, spout closure and removable filter be positioned for pouring? action
- What observed leaks, loose parts, outlet obstructions or handle defects affect the ability to pour safely? measurement
Heat supply and operation Connects the heating arrangement to available controls and observable completion states.
Electric switching, hob control and a whistle imply different agent actions and cannot be treated as interchangeable.
Supply compatibility
Establishes whether the intended source can operate this kettle within documented constraints.
Compatible heating arrangement
Record applicable electrical ratings, base compatibility or external heat-source restrictions with their provenance.
- Which label, manual or manufacturer record establishes compatibility with the proposed supply, base or hob? provenance
- What electrical ratings or external heating constraints must be checked before heating starts? action
Heating cycle
Distinguishes selected modes, actual water condition and signals that require a response.
Target and completion
Record available targets and modes, what each indication means, and whether heat stops automatically.
- Which controls select boiling, a temperature target or temperature holding, where those functions exist? definition
- What evidence indicates completion, and does that indication interrupt heating or require an operator to do so? action
- Is the recorded water temperature measured, inferred from operation or merely a selected target? measurement
Hot water and energy safety Records exposure routes and verified safeguards relevant to heating, lifting and refilling.
Steam, hot water and the heat source create distinct hazards whose controls depend on the kettle's configuration.
Thermal exposure
Identifies where heat and steam affect permitted handling.
Handling and steam path
Record intended grip surfaces, steam outlets and documented handling or lid-opening restrictions.
- Where does steam leave during heating and pouring, and which surfaces are intended for gripping? definition
- What handling, cooling or lid-opening conditions must be satisfied before moving or refilling the kettle? action
Protective functions
Separates verified protection capabilities from assumptions based on appearance or appliance type.
Protection and fault response
Record documented protective functions, observed fault indications and the prescribed response without deliberately provoking hazardous conditions.
- What evidence establishes the presence and limits of automatic shutoff, dry-heating protection or other protective functions? provenance
- What isolation, cooling, inspection or service action is prescribed after a protection trip, leak or failure to stop heating? action
Water-contact care and serviceability Tracks deposits, water-contact surfaces and defects against documented cleaning and service constraints.
Repeated water heating makes scale and wetted-surface condition central to kettle readiness, while cleaning must respect heating and electrical components.
Deposits and cleaning
Connects observed residue and removable components to a compatible maintenance method.
Scale and wetted surfaces
Record visible deposits, affected surfaces and supported cleaning methods without assuming that every residue is mineral scale.
- Where are deposits, discoloration or debris observed, and what evidence identifies their nature? measurement
- Which cleaning agents, descaling procedure and rinsing steps are documented as compatible with the wetted materials? action
- Which parts may be removed, washed or immersed, and what drying or reassembly conditions apply? action
Continued-use evidence
Assesses defects and applicable documentation before returning a kettle to operation.
Service and conformity record
Record observable defects, permitted repairs and applicable conformity evidence while separating a marked claim from independently verified compliance.
- Which observed vessel, handle, cord, connector or control defects require withdrawal from use or qualified service under the applicable instructions? action
- Which standards, issuing bodies, editions and conformity records apply to this kettle configuration and intended market? provenance
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
