# Agent Runtime Control Tools
`agent-runtime-control-tools` contains Runtime-owned tools whose semantics are
independent of a specific Agent. The initial `runtime.complete` tool provides an
explicit, validated completion boundary for Agents that require tool-driven
completion.
This is a published internal package used by reference definitions and the
definition loader. Custom tools should implement the interfaces from
`agent-runtime-sdk`.
See the [API documentation](https://docs.rs/agent-runtime-control-tools).
