Class: Identity

Defined in: lib/classes/identity.ts:71

An immutable, validated participant identity attached to a @nhtio/adk!Message.

Remarks

Carries two distinct representations of the same participant: identifier is the system-facing key (e.g. a database ID) used to correlate messages programmatically; representation is what the model sees when it needs to distinguish between participants sharing the same role. The representation is always a @nhtio/adk!Tokenizable so token cost can be estimated inline.

Constructors

Constructor

new Identity(raw: RawIdentity): Identity;

Defined in: lib/classes/identity.ts:113

Parameters

Parameter	Type	Description
raw	RawIdentity	The raw identity input validated against rawIdentitySchema.

Returns

Identity

Throws

@nhtio/adk!E_INVALID_INITIAL_IDENTITY_VALUE when raw does not satisfy the schema.

Properties

Property	Modifier	Type	Default value	Description	Defined in
identifier	readonly	string | number	undefined	The system-facing identifier for this participant — never sent to the model directly.	lib/classes/identity.ts:98
representation	readonly	Tokenizable	undefined	How this participant is presented to the model, as a @nhtio/adk!Tokenizable for inline token estimation.	lib/classes/identity.ts:104
schema	static	ObjectSchema<RawIdentity>	rawIdentitySchema	Validator schema that accepts a RawIdentity object. Remarks Reusable fragment for any schema that needs to validate or nest an identity — for example, as a required field inside a message schema.	lib/classes/identity.ts:79

Methods

isIdentity()

static isIdentity(value: unknown): value is Identity;

Defined in: lib/classes/identity.ts:91

Returns true if value is an Identity instance.

Parameters

Parameter	Type	Description
value	unknown	The value to test.

Returns

value is Identity

true when value is an Identity instance.

Remarks

Uses @nhtio/adk!isInstanceOf for cross-realm safety — instanceof would fail for instances created in a different module copy or VM context.
