wire fans the sinks into the package Logger. Each sink is wrapped in a zerolog.FilteredLevelWriter at its own level, so one log line fans to every sin

Append concatenates content to the file identified by uid, persists it locally, and mirrors the new full content best-effort. Returns ErrSizeExceeded

ApplyOutput stores a value into the scope according to the binding mode.

Card returns the metadata for the file identified by uid. Tool builders use this to translate refs into LLM-facing enums and index cards.

Chat sends a text prompt (optionally with system instructions, ID of previous response, files, images, and model options) to the LLM and returns the g

Configure wires the package Logger from cfg and returns an io.Closer that drains the HTTP sink and closes the file sink at shutdown. Call once at boot

Edit performs a single find/replace against the file identified by uid. Returns ErrEditNoMatch if oldStr isn't present. First match only, matching Cla

EnsureStrictness mutates the given JSON schema to ensure it conforms to the `strict` standard that the OpenAI API expects for function/tool calling.

FilterEmitted filters raw declared output slots to only those whose binding is emit-mode (or unbound, which defaults to emit). Used by EmitsVariables

NewSetVariable builds a SetVariable node.

WithTools sets the Tools field of the Agent.

Read a static output's binding from a node's arguments bag, keyed by the output id.

resolveLevel parses a per-sink level name, falling back to def on empty input and reporting an error — while still returning def — on an unknown name,

AsInputItems converts an Input to InputItems.

Configure must be called once per channel before channel can be written to

ExternalResourcesToDomain maps the wire ExternalResources (a keyed union of deploy-time configs) onto the engine domain type at the HTTP boundary, rou

GetProviders fetches the list of LLM providers configured on the backend and the models they expose. Used by the engine to decide which upstream provi

HandlerWithOptions creates http.Handler with additional options

NewBranchingNode creates a new BranchingNode

NewClient creates a new client with the given set of providers. Providers are constructed by a registry/wiring layer and injected here; llmproxy itsel

NewFunctionScope creates an isolated scope for function execution, with the given arguments pre-seeded under SrcFnArg and initialized declared variabl

NewTriggerNode creates a new TriggerNode

Publish sends payload to topic.

QueryRAG forwards a similarity-search query through the backend's rag/query route and returns the ranked results.

Set adds or updates a key/value pair. If the key is new, it preserves insertion order.

UIDs returns every declared memory file's uid. Used by ValidateRefs to detect refs that don't match any current declaration.

Write emits msg through the package logger at the channel's level, tagged source=workflow so the backend can separate workflow output from engine diag

buildBranchingPrompt appends a "choose one of" instruction block to steer the model toward populating the "choice" field. Emits the token→description

captureLogger points the package logger at a buffer for the duration of a test, restoring the original after.

enumNames returns the sorted keys of a name→uid map for use as a JSON schema enum. The sort is stable across calls so the schema doesn't churn.

isPrivateOrRestrictedIP blocks loopback, private (RFC 1918), link-local (including 169.254.169.254 cloud metadata), carrier-grade NAT, IPv6 unique-loc

levelWriter adapts a plain io.Writer to zerolog.LevelWriter so a FilteredLevelWriter can gate it. A writer that already carries WriteLevel (e.g. HTTPW

makeEmbedding creates a float32 slice of the given dimension filled with 0.1.
