What it does
Ngspice is an agent skill from Arcadia-1/gmoverid-skill. ngspice simulation tutorial and template skill. Provides nine standard simulation examples: (1) Transient — RC charging voltage and current; (2) DC — NMOS Id-Vds family curves; (3) AC — RC low-pass filter frequency response; (4) Noise — RC filter output noise spectral density and kT/C; (5) Transient — sample-and-hold switch comparison; (6) Transient — kT/C noise time-domain statistical measurement; (7) DC — NMOS current mirror output characteristics; (8) AC — common-source amplifier frequency response; (9) DC —…
Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 44 other files, including reference files and assets (for example `assets/ngspice_common.py`, `assets/plot_ac_cs_amp.py` and `assets/plot_ac_rc_filter.py`).
It works with Python. The repository describes itself as: Agent skill for simulating gmoverid characteristics and gmoverid-based design.
Example prompts
- “/ngspice”
Requirements
- Python 3
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Copy all files under assets/ to the project directory.
- Run any entry-point script
What it can do on your machine
Read from SKILL.md and the folder at commit 8feb841. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (Python, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Ngspice loads about 3.6k tokens when it runs, and up to ~5.1k if it reads all its reference files. Until then it costs about 150 tokens; SKILL.md has 1,206 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,206 words (~3,627 tokens).
“Dependencies: system-installed ngspice, Python 3 with numpy ≥ 1.20, matplotlib ≥ 3.3, scipy ≥ 1.7 (NumPy 1.x and 2.x both supported).”

How do I install Ngspice in Claude Code?
Run `npx skills add Arcadia-1/gmoverid-skill --skill ngspice -a claude-code`. Or copy the skill folder (ngspice in Arcadia-1/gmoverid-skill) into .claude/skills/ngspice in your project. Claude Code loads it when a task matches its description.
How do I install Ngspice in Codex?
Run `npx skills add Arcadia-1/gmoverid-skill --skill ngspice -a codex`. Or copy the skill folder (ngspice in Arcadia-1/gmoverid-skill) into .agents/skills/ngspice in your project. Codex loads it when a task matches its description.
Can I use Ngspice in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Arcadia-1/gmoverid-skill --skill ngspice -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ngspice, .gemini/skills/ngspice, .github/skills/ngspice and .opencode/skills/ngspice in your project.
What does Ngspice need to run?
Going by SKILL.md and its folder, Ngspice needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.
Does Ngspice access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Ngspice safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Ngspice use?
No licence was found for Ngspice or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Ngspice use?
About 3.6k tokens (SKILL.md is roughly 15k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.4k tokens, read only when the agent opens those files.
What are the alternatives to Ngspice?
Skills that share tags, products or a category with Ngspice: MCP Server Builder (anthropics/skills, 180k stars), PDF Processing (anthropics/skills, 180k stars), NotebookLM Research Assistant (PleasePrompto/notebooklm-skill, 7.8k stars) and Manim Video Production (browser-use/video-use, 29k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
