Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.02948 |
| Opus 5 | $0.00046 | $0.01474 |
| Sonnet 5 | $0.00018 | $0.00590 |
| Haiku 4.5 | $0.00009 | $0.00295 |
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 12d ago.
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 — 299 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 --no-project scripts/generate_bom.py --interactive
Generate from JSON configuration:
uv run --no-project scripts/generate_bom.py --json assets/example-project.json --output bom.xlsx
List component database:
uv run --no-project 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
3 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.
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.
- 12d ago First seen · 299 lines · 91 tokens per session scan A 42b50c4400b2
bom-generator is a skill published in the GitHub repository wedsamuel1230/arduino-skills (21 stars, last pushed 23d ago), licensed MIT. It adds 91 tokens to every session and 2,948 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
