Reference

Use reference when you know what you want to call. For an end-to-end application, start with the tutorial; for a design decision, use choose an approach.

Package references

Reference	Covers
Package map	All workspace packages and public entry points
Core	All 632 root exports, organized by capability
@agentium/harness	Complete public declarations: definitions, runtime, drivers, policies, sessions, events, manifests, watches, and testing
Transport	All 65 exports for HTTP, Socket.IO, and protocol hosting
Queue	All 18 exports for producers, workers, scheduling, and durable delivery
Agent types	Agent configuration and run contracts
Model types	Provider, message, response, and streaming types

The core root, transport, queue, and both harness entrypoints have reference pages generated from fresh SDK declarations. Companion type guides explain selected contracts. Core toolkit implementations remain documented in their integration guides. The installed package’s exported TypeScript declarations are the definitive type surface for that build. Use your editor’s type information when checking optional fields or overloads; do not substitute types from a different release.

Companion package guides

The other six packages have task and configuration guides. These are curated explanations, not generated coverage of every declaration.

`@agentium/edge`	Device tools and runtime	Runtime monitoring
`@agentium/eval`	Suites and scorers	Runnable quality gate
`@agentium/observability`	Instrumentation	Exporter directory
`@agentium/admin`	Configuration API	Configuration storage
