BF ros2-engineering-skills
Comprehensive ROS 2 engineering guide covering workspace setup, node architecture, communication patterns (topics/services/actions with QoS), lifecycle and component nodes, launch composition, tf2/URDF, ros2_control hardware interfaces, real-time constraints, Nav2, MoveIt 2, perception pipelines, simulation (Gazebo/Isaac Sim), security (SROS2/DDS), micro-ROS (MCU/RTOS), multi-robot systems (fleet management/Open-RMF), testing, debugging, deployment, and ROS 1 migration. Trigger whenever the user works on ROS 2 code, packages, launch files, URDF/xacro, DDS configuration, ros2_control, Nav2, MoveIt 2, or any robotics middleware task involving rclcpp, rclpy, colcon, ament, rosbag2, ros2 CLI tools, Gazebo/Isaac Sim, micro-ROS, SROS2, or multi-robot coordination. Also trigger for ROS 1 to ROS 2 migration, cross-compilation, Docker-based ROS 2 workflows, and CI/CD for robotics.

As a process F 50/100 · Will not run — References files that are not bundled: references/*.md
How to improve
- The text references files that are not there: add them or drop the references.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Against the Agent Skills spec
- warning
missing-refreference to a missing file: references/*.md - note
edit-residuethe text marks something as outdated (lines 278, 296): check that old rules are not kept next to new ones — the full check reads the text for contradictions
Process rating: all ten parameters 50/100
- 0Tools and files. 1 referenced file(s) missing: references/*.md
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 50Failures and branches. 0 branches, has a failure section
- 70Execution cost. Instruction body is 4810 tokens
- 100Steps. 50 steps
- 100When it triggers. States when to use and when not to
- 100Consistency. Name and required fields are in place
- 100Running it twice. Mutating operations check current state
- 100Progress reporting. Reports progress
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
