Exports

Section titled “Exports”
Kind Export Description
class ScriptedToolCall One scripted model tool call; the scripted sandbox runs exactly this call.
type alias ScriptStep One model turn in a test script: a reply, a tool call, or a faux step.
type alias MemoryHostOptions Optional canonical Agent inputs and a borrowed owner; defaults are in-memory.
type alias MemoryHost Explicitly driven in-process host for trusted tests and runnable examples.
function fauxModelSource() A deterministic model source for trusted tests; no provider account or I/O.
function callTool() Script one model turn that calls an operation with this input.
function echoSystemPrompt() Script one model turn that replies with the system prompt it received.
function memoryHost() Compose the real Shiitake runtime over an optional borrowed SQLite owner. Call reconcile/settle explicitly after acceptance. Defaults use a faux model and rejecting sandbox; custom callbacks are NOT isolation and retain host privileges. No submitted JavaScript is evaluated by this helper.
