What's Inside
Skills2
oscilloscope
/oscilloscope
Drive a benchtop oscilloscope via VISA / USBTMC for hardware bring-up and waveform verification. Supports two scopes auto-detected at connect time — Keysight / Agilent InfiniiVision DSO5000-series (tested DSO5012A) and RIGOL DS1000Z-series (tested DS1102Z-E). Use this skill ANY time the user mentions the scope, oscilloscope, 示波器, DSO5012A, DS1102Z-E, DS1000Z, capturing waveforms, taking screenshots from the scope, CSV waveform data, SCPI commands, trigger setup, or pre/post-bridge measurements. Also use when the user reports problems like "trace is missing", "trigger isn't firing", "波形抓不到", or wants to verify firmware output on hardware. Self-contained — bundles the helper script and a venv bootstrap so it works without `~/Work/scope/` being set up. Knows the project-specific quirks (×100 probe lock on Keysight, BMP-not-PNG on Keysight, channel-display footgun, AUTO-SCALE override, RIGOL USBTMC pipe-stall recovery, RIGOL binary-block settle delay).
rs485-modbus
/rs485-modbus
Drive a USB-to-RS485 dongle as a Modbus RTU master via the bundled `modbus.py` helper for firmware bring-up, register dump, and protocol-level debugging. Use this skill ANY time the user mentions RS485, Modbus, Modbus RTU, holding/input registers, function codes (FC=03/04/06/10), CRC errors, "波特率", "从机地址", "寄存器", USB-RS485 adapter (FT232/CH340/CP210x), or wants to ping/read/write a Modbus slave from the Mac. Also use when the user says things like "测试 Modbus 通信", "读一下版本号", "发个起始命令", "the slave isn't responding", or is debugging a STM32/embedded firmware that exposes a Modbus interface. Self-contained — bundles the helper script + venv bootstrap; no external Modbus tooling required. Knows the emst-core preset (port `/dev/cu.usbserial-A50285BI`, slave 1, 115200 8N1, register map for VERSION/CMD/LEVEL/STATE).
README
tt-skills
Personal Claude Code skill collection by @HuMoran.
A curated set of broadly useful skills I extract from real engineering work and reuse across projects. Distributed as a Claude Code plugin marketplace.
Skills
| Name | Description |
|---|---|
oscilloscope | Drive Keysight DSO5000-series and RIGOL DS1000Z-series benchtop scopes over VISA / USBTMC. Auto-detects vendor by *IDN?; bundles a self-contained scope.py with screenshots, CSV capture, triggering, deep memory, mask test, FFT, USB pipe-stall recovery. |
rs485-modbus | Drive a USB-to-RS485 dongle (FT232 / CH340 / CP210x) as a Modbus RTU master from the Mac. Pure pyserial + hand-rolled CRC — no pymodbus, no mbpoll. Two layers: generic (any port/slave/register) and project-preset (defaults baked in). |
More to come.
Install
Option A — Claude Code plugin (recommended for others)
/plugin marketplace add HuMoran/tt-skills
/plugin install tt-skills@tt-skills
Claude Code clones the repo into its plugin cache and registers all skills under the tt-skills: namespace (e.g. tt-skills:oscilloscope).
Option B — Manual clone + symlink (recommended for the author / dev workflow)
# Clone the source-of-truth
git clone https://github.com/HuMoran/tt-skills.git ~/Claude/tt-skills
# Expose each skill to Claude Code via symlink
ln -s ~/Claude/tt-skills/skills/oscilloscope ~/.claude/skills/oscilloscope
ln -s ~/Claude/tt-skills/skills/rs485-modbus ~/.claude/skills/rs485-modbus
Changes to files in ~/Claude/tt-skills/ are picked up by Claude Code immediately — no plugin update needed.
Per-skill bootstrap
Some skills (notably oscilloscope) ship a setup.sh for runtime deps. After install:
bash ~/.claude/skills/oscilloscope/scripts/setup.sh # creates .venv/
The .venv/ is gitignored — every clone re-creates it.
