Author a new asset for this .claude/ template — a rule, skill, slash command, or sub-agent — following the project's conventions and wiring it into the CLAUDE.md / README.md indexes. Trigger when the user wants to add or extend a command, skill, agent, or rule (make the template itself extensible).
Bootstrap a complete ROS 2 colcon workspace from scratch — directory layout, .gitignore, top-level README, this .claude/ config, an interfaces package and a first Clean Architecture package, and a bringup package. Trigger when the user asks to create a new workspace / start a new ROS 2 project from zero.
Scaffold a Behavior Tree leaf node — plain BehaviorTree.CPP (SyncActionNode / StatefulActionNode / ConditionNode) or a BehaviorTree.ROS2 wrapper (RosActionNode / RosServiceNode / RosTopicPubNode / RosTopicSubNode) — with ports, factory/plugin registration, and XML v4 usage. Trigger when the user asks to write a behavior-tree node (not Nav 2-specific).
Scaffold a ros2_control hardware component (SystemInterface / ActuatorInterface / SensorInterface) and its bringup — the plugin (on_init/on_configure/on_activate, RT-safe read()/write()), URDF <ros2_control> wiring, controllers.yaml + launch, pluginlib export. Trigger when the user asks to integrate hardware or bring up a robot under ros2_control.
Scaffold or extend a ros2_control controller or broadcaster (ControllerInterface / ChainableControllerInterface) — base-class choice, command/state interface configuration, lifecycle, real-time-safe update(), generate_parameter_library, pluginlib export, tests. Trigger when the user asks to write a ros2_control controller or broadcaster.
Bridge a VDA 5050 v3.0.0 fleet-control interface (MQTT/JSON) onto Nav 2 under Clean Architecture — domain entities, MQTT/Nav 2 adapters behind ports, order→NavigateThroughPoses mapping, state aggregation, action handlers. Trigger when the user asks to build or extend a VDA 5050 connector / fleet bridge.
Configure and build gz-sim from source using either CMake/Ninja directly or a colcon workspace. Trigger when the user asks to build, recompile, configure, or set up the gz-sim binary tree.
Concise reference for the gz-sim Entity-Component-System architecture — how Entities, Components, Systems, the ECM, the Server, and SimulationRunner fit together. Trigger when the user asks how gz-sim is organized, where to add code, or how the simulation loop runs.
