dfrobot_matrix_lidar_8x8_i2c SKILL.md skillC

dfrobot_matrix_lidar_8x8_i2c from espressif/esp-claw-skills-lab is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add espressif/esp-claw-skills-lab/dfrobot_matrix_lidar_8x8_i2c@git:20261014.4631425

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

# DFRobot MatrixLidar 8x8 I2C

Use this skill when the user asks to read data from a DFRobot MatrixLidar, DFRobot matrix radar, 8x8 matrix lidar, 8x8 TOF sensor, or 8x8 matrix laser radar connected over I2C.

Typical user requests include:

- 读一下 DFRobot 矩阵雷达的数据
- 读取 8x8 雷达数据
- 读取 8x8 矩阵激光雷达数据
- 读取 TOF 激光测距矩阵数据
- I2C 地址是 0x33，帮我读一下矩阵雷达

Chinese aliases that should map to this skill include: 矩阵雷达、8x8 雷达、8x8 矩阵激光雷达、TOF 矩阵测距、激光测距矩阵。

Default device assumptions:

- I2C address defaults to `0x33`
- Reads one 8x8 frame of distance values in mm
- Intended for an externally connected DFRobot MatrixLidar sensor on UNIHIKER

Run exactly one bundled Lua script with `lua_run_script`.

If script execution returns an error, report that error directly to the user.
Do not retry with changed arguments in the same turn unless the user explicitly asks.

How to install

The exact contents, by fingerprint

mdr add espressif/esp-claw-skills-lab/dfrobot_matrix_lidar_8x8_i2c@sha256:41d0b8fdc1503f90

The line at the top of this page pins the label git:20261014.4631425, 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.
