# Plecs Expert > PLECS authoring help, .plecs schematic format, XML-RPC API, and SPICE-mapping reference. Use when answering "how do I X in PLECS", working on the netlist converter, or extending the PlecsServer XML-RPC wrapper. Use when this capability is needed. - Skill: `tomevault-io/plecs-expert` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/plecs-expert` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/plecs-expert/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Integrations & APIs - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/plecs-expert --- # PLECS Expert Lookup-first PLECS reference grounded in docs.plexim.com. Two layers: - **Layer A — offline docs**: `references/`. Verbatim factual tables + caveman prose. - **Layer B — pyplecs code**: `pyplecs.plecs_components`, `pyplecs.pyplecs.PlecsServer`. Live introspection. ## Routing | Topic | File | |-------|------| | Electrical passives (R, L, C, transformer) | `references/components/electrical-passive.md` | | Sources (V, I, signal) | `references/components/electrical-sources.md` | | Switches (MOSFET, IGBT, diode) | `references/components/electrical-switches.md` | | Meters & scopes | `references/components/electrical-meters.md` | | Magnetic blocks | `references/components/magnetic.md` | | Thermal blocks | `references/components/thermal.md` | | Control library | `references/components/control.md` | | Subsystems & masks | `references/components/system.md` | | XML-RPC API | `references/rpc-api.md` | | `.plecs` XML grammar | `references/plecs-xml-grammar.md` | | Solver | `references/solver.md` | | Codegen (PLECS Coder) | `references/codegen.md` | | C-Script block | `references/cscript.md` | | Long-tail topics | `references/url-index.md` (then WebFetch the listed URL) | ## Composition rule For component or RPC questions, check Layer B first. If a `*PlecsMdl` class exists in `pyplecs.plecs_components`, cite the wrapper. If a method exists on `PlecsServer`, cite it. Else cite Layer A. Else WebFetch from `references/url-index.md`. ## Citation rule Every answer cites a `references/*` path or a `docs.plexim.com` URL. No ungrounded claims. ## Style Generated prose follows `style/caveman.md`: fragments OK, drop articles/hedging/filler, pattern `[thing] [action] [reason]. [next step].`. ## Boundary This skill does not cover: PLECS RT Box (separate future skill), license/purchasing, third-party libraries. --- > Source: [tinix84/pyplecs](https://github.com/tinix84/pyplecs) — distributed by [TomeVault](https://tomevault.io).
