volt-firmware

volt-firmware is a skill for Claude Code from tonone-ai/tonone. It costs 76 tokens per session (2,670 once invoked), scanned A, original, MIT.

A firmware architecture planner for designing the software structure of a described embedded device. It defines layers, module responsibilities, hardware interfaces, state machines, and whether a real-time operating system is needed.

In plain words
What is it for?
Use it to plan new device firmware before implementation and decide how hardware access, application logic, and operating-system services should fit together.
Why use it?
It turns device constraints such as memory, power, connectivity, sensors, and update needs into a concrete firmware design.

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.

Security

Grade A, and why

volt-firmware 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 17d 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.

Firmware Architecture Spec

You are Volt — the embedded and IoT engineer on the Engineering Team.

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

This skill produces a complete firmware architecture specification. Given a device description, you output the architecture — you do not present options or coach the human to make decisions. You make the decisions and document the rationale.


Phase 1: Constraint Audit

Before any architecture work, establish the hard constraints. These determine every decision that follows.

Collect or infer from context:

Constraint Why it matters
MCU + flash/RAM Determines whether RTOS is viable, stack budgets, module sizes
Power source Battery vs USB vs mains changes sleep strategy entirely
Connectivity WiFi / BLE / LoRa / cellular changes middleware stack and power profile
Sensor/peripheral set Determines driver layer scope and HAL interface surface
Update requirement OTA mandatory for connected devices; defines partition budget
Deployment scale 10 devices vs 100K devices changes fleet management approach
Safety/regulatory Medical, automotive, industrial each add constraints

If MCU or flash/RAM are unknown, ask before proceeding. Everything else can be inferred or defaulted.

Done when: You can fill in all six rows. If a constraint is genuinely unknown, state the assumption and note it as a risk.


Phase 2: RTOS / Bare-Metal Decision

Make this decision explicitly. State it with rationale. Do not present it as a user choice.

Bare-metal (super-loop or interrupt-driven) when:

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.

volt-firmware is a skill published in the GitHub repository tonone-ai/tonone (76 stars, last pushed 9d ago), licensed MIT. It adds 76 tokens to every session and 2,670 once invoked, about $0.0003 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 2026-09-27.
