DeepSeek Harness ElectroLab
An electrical & electronics calculation plugin for the DeepSeek Harness.
Install
dsh plugin --profile web add dsh-electro-labElectroLab Mode
The plugin works as an agent preset: pick ElectroLab Mode when starting a session and ask any electrical or electronics calculation question in plain language. The session is isolated to the plugin's tools — no shell, no file system, no network — so every number in the answer comes from the engine, and the agent stops and asks when the conditions are insufficient.
All calculation happens inside a deterministic engine. The agent operates it through three primitives — set (write a typed value into a slot), get (read a slot) and call (run one of 38 math solvers and store the result) — bracketed by the record markers record_question / record_analyse / record_answer. Typed values carry their own kind, variant and prefix (e.g. {type: "number", value: 25, kind: "temperature", variant: "degC"}); the engine stores them as given and performs SI and unit conversion only at calculation boundaries. Every step lands in a per-record trace file, so each solve is a reproducible process that can be replayed without re-computing.
The solver catalog covers expression algebra, series, transfer functions, DSP/DFT, signal quality (THD, jitter, ADC budget), circuits (impedance, resonance, transients, AC power), electronics (op-amps, dividers, LED), RF & Smith chart (reflection, matching networks), transmission lines, noise, and filter design. See the engine manual.
Settled records are listed in the client panel's Records tab (indexed from record-index.jsonl, refreshed every 5 s); incomplete records are marked as such. Record bodies are process traces under ~/.dsh-electro-lab/records/. The list has a select mode (multi-select, select all, delete with confirmation) and each record opens a timeline detail page: collapsible cards for writes/reads/failures and calls, JSON tree values with zebra striping, and a fixed toolbar/title area with the timeline scrolling beneath it.
Article generation
The record detail page's right rail offers Markdown and LaTeX generation: the host LLM writes a fluent, self-contained solution article from the record's trace (question, established conditions, analysis notes, solver steps with their resolved arguments and results, and the final answer), presented as the model's own calculation — never mentioning ElectroLab, solvers or the generation process. Each button opens its own setup dialog (article language, output directory with a host-driven directory browser, file name; remembered across runs), then runs a cancellable background job whose progress dialog can be minimized to a corner pill that survives navigation. LaTeX articles are proper XeLaTeX documents (ctexart for zh-CN, fontspec + unicode-math + siunitx for en — pure Unicode throughout); PDF compilation is LaTeX-only (xelatex, two passes). Markdown output is written flat as .md and never compiled. The generated file is the primary artifact: open it or its folder straight from the progress dialog.
