What is bom-generator?

A Bill of Materials generator for Arduino, ESP32, and RP2040 projects. A Bill of Materials is a structured list of the parts needed to build something.

Planning components to buy, exporting parts lists as XLSX, CSV, Markdown, or JSON, and checking a maker project's required hardware.

It turns a project description into an organized parts list with quantities, suppliers, compatibility checks, and possible cost estimates.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00091	$0.02869
Opus 5.5	$0.00036	$0.01148
Sonnet 5.5	$0.00018	$0.00574
Haiku 4.5	$0.00009	$0.00287

Security

Grade A, and why

bom-generator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/generate_bom.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 292 lines — stays where its author put it; the contents beside it link to each section on GitHub.

BOM Generator

Creates comprehensive Bill of Materials for maker projects with supplier links and compatibility checks.

Resources

scripts/generate_bom.py - Python script for xlsx/csv/markdown BOM generation (requires openpyxl)
references/example-bom.md - Complete example BOM
assets/example-project.json - Sample project configuration for script

Quick Start

Generate BOM interactively:

uv run scripts/generate_bom.py --interactive

Generate from JSON configuration:

uv run scripts/generate_bom.py --json assets/example-project.json --output bom.xlsx

List component database:

uv run scripts/generate_bom.py --list

Export formats: xlsx (default), csv, md, json

When to Use

User describes a project and needs parts list
User asks "what components do I need for X"
User wants to order parts for a design
User needs cost estimates

Workflow

Step 1: Gather Project Requirements

Ask user for:

1. Project description (what does it do?)
2. Target microcontroller (Arduino UNO/Nano/Mega, ESP32, RP2040)
3. Power source (USB, batteries, wall adapter)
4. Quantity (how many units to build?)
5. Budget constraints (optional)
6. Supplier preference (optional)

Step 2: Generate BOM

Run scripts/generate_bom.py --interactive for guided generation, or use this template format:

# Bill of Materials: [Project Name]

**Generated:** [Date]
**Target Board:** [MCU]
**Quantity:** [N] unit(s)
**Estimated Total:** $[X.XX] - $[Y.YY] (per unit)

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

It adds 91 tokens to every session and 2,869 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
