API reference

Use the root entry for an Agent host, /client for an authorized transport, /extensions for durable contributions and /testing for local fixtures. Generated module pages below retain the complete signatures and types. AcceptedSchema from /client validates a command acceptance received as an RPC value; parseAccepted decodes its serialized JSON form.

Entry	When to use it	Start with
Root	Own durable Sessions and host resources	Shiitake, ShiitakeOptions, ShiitakeError, SqliteOwner, RuntimeHost
Client	Submit commands and observe an admitted Session	createShiitakeClient, AcceptedSchema and the returned Session client
Extensions	Define extension state, commands, tools and projections	defineExtension, defineCollection, ExtensionId, ExtensionCommandError, ExtensionStop
Testing	Run a credential-free canonical host	memoryHost, callTool, echoSystemPrompt, fauxModelSource, MemoryHostOptions
HTTP	Bind authorized Session routes to an existing host	createShiitakeHttpRoutes, ShiitakeSessionResolver, ShiitakeHttpEnv
Client entries	Turn a shared projection into bounded UI contributions	defineClientEntry, clientContributionSchemaV1
Agent control	Give admitted tools a directory of existing Agents	createAgentControlSource, waitForAgentSettlement, AgentControlDirectory

The testing host is explicitly driven and uses trusted callbacks. It is not a production isolation boundary. Start with Your first Session, then Your first extension.
