# Spec Sheet

> The technical specifications section of a hardware product page, set as one engineering drawing and its schedule. The product is drawn in true orthographic views from one spec.json, with drafting line weights, dimension lines, numbered balloons, a detail view, a hatched section and a title block. Every balloon is a line number in the table, and pointing at a line lights its part or dimension on the drawing, and the reverse. Units switch between mm and inches and between kg and pounds, with the rounding printed in the drawing's notes. Compare mode sets up to 3 models side by side, writes shared values once and draws the other models as phantom lines. The build checks every drawn dimension against the table, and the sheet prints on one landscape page.

- Output: Web, page kit · drawing + spec table · page + embed · 1080p video
- Price: Free
- Page: https://lookbk.dev/skills/spec-sheet-kit

## What you need

- Node.js 18 or newer. Nothing to install.
- Chrome, Chromium or Edge, for the checks, the print check and the video (the scripts find it; set `CHROME_PATH` if they don't).
- ffmpeg for the video and the print picture only (`brew install ffmpeg`, `winget install ffmpeg`, `apt install ffmpeg`; or set `FFMPEG_PATH`).
- The product's real dimensions, in millimetres, and a rough sketch of its outline in each view (see step 2). Internet access when the page is opened, for the Google Fonts.

## Install

```bash
curl -fsSL https://lookbk.dev/cli.js | node - add spec-sheet-kit
```

The first run prints a sign-in link; open it, approve, and run the command again.

Where it installs:

- Run by Claude Code: `~/.claude/skills/spec-sheet-kit` only, the one folder Claude Code reads.
- From your own terminal: `~/.agents/skills/spec-sheet-kit`, which Codex, Gemini CLI, Copilot CLI, Cursor and OpenCode read, and also `~/.claude/skills/spec-sheet-kit` when `~/.claude` exists.

Add `--claude` or `--shared` to write only one of those folders, or `--project` to install into the current folder instead. Start a new agent session afterwards so it picks up the skill.
