echo

Overview ¶

Package echo is a worked, runnable Harbor agent example.

It implements the public harbortest.Agent interface — the same interface `harbor scaffold`'s minimal-react template produces — so it can be exercised end-to-end with harbortest.RunOnce without constructing an engine graph by hand.

EchoAgent is deliberately trivial (it returns its input unchanged): the value of this example is the SHAPE, not the behaviour. Copy this package, keep the harbortest.Agent satisfaction and the compile-time assertion, and replace Run's body with a planner step, a flow invocation, or a hand-rolled tool-call sequence.

See docs/recipes/ for the companion how-to guides and examples/tools/ for a worked in-process tool.
