Health verifies that the LLM service is available and responding. Returns an error if the service is unreachable or unhealthy.

NewAgent creates a new Agent with the given name and applies any provided options.

WithInstructions sets the Instructions field of the Agent.

mf is a terse MemoryFile builder for declarations and snapshots.

* Apply an update to one function. `bumpVersion` is true for signature changes * (name/arguments/outputs declaration) so call sites detect staleness,

nextDelay returns the duration from now until the next matching fire time. Always strictly positive — if HH:MM has already passed today (or today is n

passthroughFn returns a Function with one Int arg "a" and one Int return "ret" where ret = a (passthrough). InitialState is idle so Function.Call eval

CloseAll shuts down every driver. Returns the first error encountered; keeps going on failures so no handle leaks.

NewManager constructs a manager whose durable copy lives in dir. The directory is created lazily on Reconcile.

Read returns the current content of the file identified by uid.

Reconcile converges the working copy to the files declared by the current deploy. Called from Builder.Build, so every deploy reconciles state (boot an

matches reports whether an edge of the given polarity matches the trigger's configured filter.

next resolves and applies the outgoing transition. `choice` is the model- emitted token ("choice_N") — consulted only when multiple branches exist, ig

parseChoiceToken extracts the branch index from a choice_N token and verifies it is within range.

Cast converts a value to the target data type.

NewLinearNode creates a new LinearNode

NewTestRunner creates a new Runner with the given mock provider for testing purposes.

Read blocks until one line arrives (therefore takes context). Errors if another Read is in flight.

applyStructuredOutputs extracts the answer + each declared output from the parsed JSON and routes each value to its destination. "answer" goes through

buildResponseFormat constructs the JSON schema covering "answer", each declared output (keyed by name), and a "choice" enum for multi-branch agents. B

choiceToken is the opaque enum value placed in the response schema for the branch at index i. Kept short and stable so the model can reproduce it reli

newEmbeddingTestServer creates an httptest server that handles /v1/models and /v1/embeddings. The embeddingHandler is called for POST /v1/embeddings.

newTestEmbeddingProvider creates a Provider with a single embedding model pointing to the given server URL.

newTestProvider returns a MockProvider with default behavior for its ID.

ApplyDeclaration stores a value into the scope according to the declaration mode.

LastUserInput returns the last user-provided text from an Input. For InputString it returns the string itself; for InputItems it returns the last Inpu

NewIf builds an If node.

Slice maps a slice of type A to a slice of type B, passing pointers to mappingFunc

closeFamily closes every driver in a map, draining it as it goes. Records the first Close error via firstErr; subsequent errors are dropped so all han

* Recursively infer the type of an AST node

lookup returns the driver registered under id in the given typed map, or an error labelled with the family name.

newMockllmClient creates a new instance of mockllmClient. It also registers a testing interface on the mock and a cleanup function to assert the mocks

newTestPinEdge constructs an OnPinEdge wired to the given event channel. Bypasses NewOnPinEdge to avoid needing a real channel.GPIOInput.
