Struct HarnessBuilder 

pub struct HarnessBuilder { /* private fields */ }

Builds a Harness with runtime-friendly defaults.

Use this when embedding Everruns directly and seeding a harness in code. IDs and timestamps are generated at build time unless explicitly set.

Implementations

impl HarnessBuilder

pub fn new( name: impl Into<String>, system_prompt: impl Into<String>, ) -> HarnessBuilder

Create a harness builder from the required embedder-facing fields.

pub fn id(self, id: TypedId<HarnessIdMarker>) -> HarnessBuilder

Set a stable harness id instead of generating one.

pub fn harness_id(&self) -> TypedId<HarnessIdMarker>

Return the id currently assigned to this builder.

pub fn name(self, name: impl Into<String>) -> HarnessBuilder

pub fn display_name(self, display_name: impl Into<String>) -> HarnessBuilder

pub fn description(self, description: impl Into<String>) -> HarnessBuilder

pub fn system_prompt(self, system_prompt: impl Into<String>) -> HarnessBuilder

pub fn parent_harness_id( self, parent_harness_id: TypedId<HarnessIdMarker>, ) -> HarnessBuilder

pub fn default_model_id( self, default_model_id: TypedId<ModelIdMarker>, ) -> HarnessBuilder

pub fn tag(self, tag: impl Into<String>) -> HarnessBuilder

pub fn tags<I, S>(self, tags: I) -> HarnessBuilder

where I: IntoIterator<Item = S>, S: Into<String>,

pub fn capability( self, capability: impl Into<AgentCapabilityConfig>, ) -> HarnessBuilder

pub fn with_capability( self, capability: impl Into<AgentCapabilityConfig>, ) -> HarnessBuilder

pub fn capabilities<I, C>(self, capabilities: I) -> HarnessBuilder

where I: IntoIterator<Item = C>, C: Into<AgentCapabilityConfig>,

pub fn initial_file(self, file: InitialFile) -> HarnessBuilder

pub fn network_access(self, network_access: NetworkAccessList) -> HarnessBuilder

pub fn parallel_tool_calls(self, parallel_tool_calls: bool) -> HarnessBuilder

Set the request-level parallel tool calling preference (EVE-598).

pub fn mcp_servers( self, mcp_servers: BTreeMap<String, ScopedMcpServer>, ) -> HarnessBuilder

pub fn metadata_entry( self, key: impl Into<String>, value: impl Into<String>, ) -> HarnessBuilder

pub fn metadata_entries<I, K, V>(self, entries: I) -> HarnessBuilder

where I: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<String>,

pub fn openrouter_attribution( self, http_referer: impl Into<String>, title: impl Into<String>, ) -> HarnessBuilder

Set OpenRouter attribution headers for LLM calls made by this harness.

The values flow through harness embedder metadata and are sent by the OpenRouter driver as HTTP-Referer and X-Title.

pub fn is_built_in(self, is_built_in: bool) -> HarnessBuilder

pub fn status(self, status: HarnessStatus) -> HarnessBuilder

pub fn created_at(self, created_at: DateTime<Utc>) -> HarnessBuilder

pub fn updated_at(self, updated_at: DateTime<Utc>) -> HarnessBuilder

pub fn build(self) -> Harness

Build the harness. Builders do not validate domain invariants.
