Overview

Package engine is the stable, host-facing Eyrie API.

Hosts should prefer this package over assembling client, catalog, config, credentials, runtime, and setup packages directly. The lower-level packages remain public for backward compatibility and advanced integrations.

Engine is intentionally stateless with respect to product conversations: the host owns conversation history, tools, permissions, and checkpoints; Eyrie owns credential, catalog, selection, routing, and model transport.

Host-facing DTOs and the Provider port live in github.com/GrayCodeAI/hawk-core-contracts/llm; this package re-exports them as type aliases and *Engine implements llm.Provider (see contract_assert.go).

var SetDefaultStore = credentials.SetDefaultStore

SetDefaultStore replaces the process-wide credential store (for tests).

Functions

func AccountForEnv 

func AccountForEnv(envVar string) string

AccountForEnv returns the keychain account name for an env var.

func CredentialGuidance 

func CredentialGuidance(providerID, secret string) string

CredentialGuidance returns provider-specific, non-secret setup guidance.

func DefaultThinkingDisabled 

func DefaultThinkingDisabled(providerID string) bool

DefaultThinkingDisabled reports whether a provider defaults thinking OFF when unset.

func FormatPreflight 

func FormatPreflight(report PreflightReport) string

func FormatSetupError 

func FormatSetupError(providerID string, err error) string

FormatSetupError returns a safe provider setup hint.

func HasSecret 

func HasSecret(ctx context.Context, envKey string) bool

HasSecret reports whether a secret exists for an env var (for tests).

func IsCatalogCacheRequired 

func IsCatalogCacheRequired(err error) bool

IsCatalogCacheRequired reports whether an operation needs the local model catalog to be refreshed before it can continue.

func IsCode 

func IsCode(err error, code ErrorCode) bool

IsCode reports whether err or an error in its chain has the supplied code.

func MigrateEnvFileCredentials 

func MigrateEnvFileCredentials(ctx context.Context) (int, error)

func NormalizeProviderID 

func NormalizeProviderID(providerID string) string

NormalizeProviderID resolves provider aliases to Eyrie's runtime identifier.

func RegisterCustomGateway 

func RegisterCustomGateway(gateway CustomGateway) error

RegisterCustomGateway registers safe OpenAI-compatible routing metadata for compatibility callers. New embedders should pass Options.CustomGateways so instances stay isolated. Registration must happen before Engine creation; each Engine snapshots the metadata and always resolves credentials through its own injected SecretStore.

func RegisteredGatewayCount 

func RegisteredGatewayCount() int

RegisteredGatewayCount returns the first-class provider count from the provider registry. Hosts derive provider counts from Eyrie instead of hard-coding them, so new providers require no host changes.

func SecretStoreName 

func SecretStoreName() string

SecretStoreName is safe presentation metadata for host UIs.

func SetSecretStoreServiceName 

func SetSecretStoreServiceName(name string)

SetSecretStoreServiceName overrides the OS secret-store service name (default "eyrie"). Hosts call this once at startup so existing credentials filed under their product name (e.g. "hawk") stay readable.

func ThinkingToggleSupported 

func ThinkingToggleSupported(providerID string) bool

ThinkingToggleSupported reports whether a provider's wire protocol honors thinking toggles.

Types

type CatalogHealth 

type CatalogHealth = llm.CatalogHealth

CatalogHealth is the host-facing catalog health report.

type CatalogSnapshot 

type CatalogSnapshot = llm.CatalogSnapshot

CatalogSnapshot is an immutable host-facing view of a loaded catalog. It is a type alias to the canonical llm.CatalogSnapshot so exactly one struct crosses the host boundary (matching every other type in this file).

type CheckStatus 

type CheckStatus = llm.CheckStatus

CheckStatus is a preflight check status.

type ContentPart 

type ContentPart = llm.ContentPart

ContentPart is a provider-neutral multimodal message part.

type CredentialProvider 

type CredentialProvider = llm.CredentialProviderOption

CredentialProvider is safe setup metadata for a configurable provider. It contains identifiers and labels only, never credential material.

type CredentialResolution 

type CredentialResolution = llm.CredentialResolution

CredentialResolution validates pasted input and returns provider choices. The input secret is never retained in this value.

type CredentialStatus 

type CredentialStatus = llm.CredentialStatus

CredentialStatus is safe to render or log; it never contains a secret.

type CredentialStorageReport 

type CredentialStorageReport struct {
	PlatformStore string `json:"platform_store"`
	Writable      bool   `json:"writable"`
	Detail        string `json:"detail,omitempty"`
	Formatted     string `json:"formatted,omitempty"`
}

CredentialStorageReport is safe to print and never includes secrets.

func CredentialStorage 

func CredentialStorage(ctx context.Context) CredentialStorageReport

type CustomGateway 

type CustomGateway struct {
	ID             string                     `json:"id"`
	DisplayName    string                     `json:"display_name,omitempty"`
	BaseURL        string                     `json:"base_url"`
	CredentialEnv  string                     `json:"credential_env,omitempty"`
	DefaultModel   string                     `json:"default_model,omitempty"`
	MaxTokensField string                     `json:"max_tokens_field,omitempty"`
	ContextWindow  int                        `json:"context_window,omitempty"`
	SortOrder      int                        `json:"sort_order,omitempty"`
	ChatPreference int                        `json:"chat_preference,omitempty"`
	Capabilities   *CustomGatewayCapabilities `json:"capabilities,omitempty"`
}

CustomGateway describes a user-configured OpenAI-compatible gateway. It contains only routing metadata; credential material remains in Eyrie's secret store and is discovered by CredentialEnv.

type CustomGatewayCapabilities 

type CustomGatewayCapabilities struct {
	Streaming      bool `json:"streaming,omitempty"`
	Tools          bool `json:"tools,omitempty"`
	Vision         bool `json:"vision,omitempty"`
	StructuredJSON bool `json:"structured_json,omitempty"`
	Reasoning      bool `json:"reasoning,omitempty"`
}

CustomGatewayCapabilities declares capabilities known to be supported by a custom OpenAI-compatible gateway. A nil declaration is permissive for backward compatibility: the remote gateway remains the source of truth.

	// explicitly declares that the host has no custom gateways.
	CustomGateways []CustomGateway
	// UseRegisteredCustomGateways opts into the deprecated process-global
	// RegisterCustomGateway registry when CustomGateways is nil.
	UseRegisteredCustomGateways bool
	// EnableRateLimiting wraps resolved transports with an adaptive rate
	// limiter that backs off when approaching provider limits. Off by default.
