Record Class AgentStart

java.lang.Object

java.lang.Record

com.tnsai.hooks.events.AgentStart

Record Components:

eventId - ULID-shaped correlation id

timestamp - when first chat started

context - surrounding hook context

All Implemented Interfaces:

AgentHookEvent, HookEvent

public record AgentStart(String eventId, Instant timestamp, HookContext context)
extends Record
implements AgentHookEvent

Fires once when an agent is about to handle its first chat (issue #60). Distinct from AgentInit: AgentInit runs at build time; AgentStart runs at first use. Use for lazy warm-up — LLM connection probes, metric collector start — that should wait until the agent is actually exercised.

Guarded by an AtomicBoolean at the orchestrator (follow-up): fires exactly once per agent instance.

Since:

0.5.0 (issue #60)

Constructor Details

AgentStart

public AgentStart(String eventId,
 Instant timestamp,
 HookContext context)

Creates an instance of a AgentStart record class.

Parameters:

eventId - the value for the eventId record component

timestamp - the value for the timestamp record component

context - the value for the context record component

Method Details

eventType

public String eventType()

Description copied from interface: HookEvent

Short stable string identifier of the event kind, e.g. "PreToolUse". Default implementation derives it from the concrete record's simple class name; concrete records may override if a different naming is desirable.

Specified by:

eventType in interface HookEvent

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

eventId

public String eventId()

Returns the value of the eventId record component.

Specified by:

eventId in interface HookEvent

Returns:

the value of the eventId record component

timestamp

public Instant timestamp()

Returns the value of the timestamp record component.

Specified by:

timestamp in interface HookEvent

Returns:

the value of the timestamp record component

context

public HookContext context()

Returns the value of the context record component.

Specified by:

context in interface HookEvent

Returns:

the value of the context record component
