# DeepSeek Harness ElectroLab

An electrical & electronics calculation plugin for the DeepSeek Harness.

[简体中文](README.zh-CN.md)

## Install

```sh
dsh plugin --profile web add dsh-electro-lab
```

## ElectroLab 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](docs/engine.md).

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.
