EveProtocol

NexusLabs.Eve

EveProtocol Class

Identifies the eve protocol revision implemented by this package.

public static class EveProtocol

Inheritance System.Object → EveProtocol

Fields

EveProtocol.MessageStreamContentType Field

Gets the media type returned by eve session streams.

public const string MessageStreamContentType = "application/x-ndjson";

Field Value

System.String

EveProtocol.MessageStreamVersion Field

Gets the durable message-stream protocol version used by the reference client.

public const string MessageStreamVersion = "25";

Field Value

System.String

Remarks

This mirrors upstream's EVE_MESSAGE_STREAM_VERSION in packages/eve/src/protocol/message.ts. Read that constant when advancing the baseline; the value does not follow from whether the event vocabulary changed. eve 0.35.0 raised it to 22 while adding no event type and removing none. The 0.39.1 raised it to 23 for durable input.resolved events, 0.46.1 raised it to 24 for durable action.input.appended events, and 0.50.0 raised it to 25 for delta-only text streaming.

EveProtocol.MinimumEveVersion Field

Gets the oldest eve release this package can talk to.

public const string MinimumEveVersion = "0.54.2";

Field Value

System.String

Remarks

eve 0.54.2 is the first published release whose schema-v4 kernel-effect action set excludes the obsolete task-update value. Earlier schema-v4 servers use the same version number and can still advertise that action, so there is no discriminator that permits strict validation across the cutover. Separately, eve 0.52.3 added the accepted-message delivery identity required to correlate an existing-session send with its durable events. Upgrade the eve server before adopting a client version that declares this minimum. The message-stream protocol remains version 25.

EveProtocol.ReferenceEveVersion Field

Gets the upstream TypeScript package version used as the compatibility reference.

public const string ReferenceEveVersion = "0.63.0";

Field Value

System.String

EveProtocol.SessionIdHeaderName Field

Gets the response header that carries the assigned eve session identifier.

public const string SessionIdHeaderName = "x-eve-session-id";

Field Value

System.String

EveProtocol.StreamControlVersion Field

Gets the transport-control version used to renew leased session stream responses.

public const string StreamControlVersion = "1";

Field Value

System.String

Remarks

Eligible absolute-cursor streams send this version through the internal streamControlVersion query parameter. Lease control records remain internal and are never projected as durable EveStreamEvent values.

EveProtocol.StreamVersionHeaderName Field

Gets the response header that carries the stream protocol version.

public const string StreamVersionHeaderName = "x-eve-stream-version";

Field Value

System.String

EveProtocol.VercelTrustedOidcTokenHeaderName Field

Gets the Vercel header used to present a trusted OIDC identity-provider token.

public const string VercelTrustedOidcTokenHeaderName = "x-vercel-trusted-oidc-idp-token";

Field Value

System.String

Properties

EveProtocol.SupportedAgentInfoVersions Property

Gets the agent-info payload schema versions this package understands.

public static System.Collections.Generic.IReadOnlyList<int> SupportedAgentInfoVersions { get; }

Property Value

System.Collections.Generic.IReadOnlyList<System.Int32>

Remarks

eve raised the schema to 2 in 0.35.0, where static instructions became a list whose entries carry content and a system or user role. Eve 0.45.0 uses version 3 for canonical source ownership, bindings, composition diagnostics, node identities, and kernel effects. Eve 0.45.1 raised it to version 4 for first-class memory-provider inspection. Schema v3 preserves the historical task-update kernel-effect action, while the schema-v4 contract published by eve 0.54.2 accepts only subagent-call, task-cancel, and workflow-tool-call. Eve 0.56.0 retained schema version 4 while making legacy workflow metadata optional, so both schema-v4 shapes are accepted. Every supported version exposes the identity fields this package projects, and its complete payload remains available through Raw. A version outside this set is rejected rather than parsed optimistically.
