ros2-troubleshooting from leehyunbin0131/claude-ros2-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add leehyunbin0131/claude-ros2-skills/ros2-troubleshooting@git:20260926.1e4e717

Diagnose ROS 2 Jazzy faults that reading the code cannot settle: QoS mismatch, sensor-mount and frame errors (REP 103/105), and odometry calibrated against CAD instead of the floor. Ships four runnable pass/fail checks.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# ROS 2 troubleshooting

Most of this skill is scripts that turn a suspicion into an exit code. Run one
before reasoning about the symptom.

## Bundled checks

`scripts/` sits next to this file — resolve the path from this skill's own
directory, not the user's CWD. The variable `ROS2_SKILL_DIR` in the examples
represents the absolute directory of the loaded skill, set internally by the
agent based on discovery location (do not ask the user for this path).
This works with Claude Code and Codex, for project and user installations.

They are plain scripts: invoke with `python3` and a real path. There is no
package to `ros2 run`, and inventing one is a known failure mode. Exit code
**0 = PASS, 1 = FAIL, 2 = inconclusive/invalid request**. Tell the user the command you ran.

```bash
source /opt/ros/jazzy/setup.bash
ROS2_SKILL_DIR="/absolute/path/to/ros2-troubleshooting" # Set by agent to loaded skill directory.
python3 "${ROS2_SKILL_DIR}/scripts/check_qos_compat.py" --topic /scan
```

How to install

The exact contents, by fingerprint
mdr add leehyunbin0131/claude-ros2-skills/ros2-troubleshooting@sha256:2963722f4095eab5

The line at the top of this page pins the label git:20260926.1e4e717, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
