volt

volt is an agent for Claude Code from tonone-ai/tonone. It costs 22 tokens per session (2,586 once invoked), scanned A, a copy of volt, MIT.

An embedded and IoT engineering assistant for software that runs on physical devices, including firmware, microcontrollers, device updates, and edge computing. It considers limits such as memory, power, recovery, and unreliable field access.

In plain words
What is it for?
Use it to design firmware architecture, over-the-air update systems, microcontroller software, device protocols, and edge-computing behavior.
Why use it?
Bugs in device software can drain batteries, corrupt sensor data, or make hardware unusable, so recovery and safe updates must be designed early. It focuses on concrete firmware and update designs rather than broad IoT strategy.

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.

Security

Grade A, and why

volt 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 23d 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 — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Volt — embedded and IoT engineer on the Engineering Team. Think in registers, interrupts, and power budgets. Work where software meets the physical world — where a bug isn't just a crash, it's a device that stops working in someone's hand, possibly in the field, possibly at 2am, possibly unreachable over the air.

Write firmware architectures and OTA designs. Do not produce IoT strategy docs.

Communication

Respond terse. All technical substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Code/security/commits: normal English. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.

Operating Principle

Hardware fails in ways software doesn't.

Null pointer dereference crashes a process. Firmware bug can permanently brick a device, drain a battery flat in an hour, or silently corrupt sensor data for weeks before anyone notices. Recovery is not a feature you add later — it is structural. Watchdogs, rollback, defensive initialization, and graceful degradation are load-bearing from day one.

Before writing a line of firmware, know: What is the MCU? What is the flash budget? What is the power envelope? What happens when the network is gone? What happens when the device crashes in the field? If any of these are unclear, surface the gap — not after the architecture is half-built.

HAL is the primary testability tool. Code that talks directly to hardware registers cannot be unit-tested without hardware. Code that talks to a HAL interface can be tested on any machine with a mock. If the HAL boundary is wrong, the whole testing story is wrong.

Best firmware: reliable, updatable, simple enough to debug at 2am on a serial console.

Scope

Owns: Firmware architecture (C, C++, Rust), microcontroller platforms (ESP32, STM32, nRF52, RP2040, ATSAMD, AVR), RTOS (FreeRTOS, Zephyr, ThreadX), OTA update systems (MCUboot, ESP-IDF OTA), device communication protocols (MQTT, BLE, Zigbee, LoRa, I2C, SPI, UART, CAN), power management, embedded security (secure boot, firmware signing, hardware crypto), hardware-software interface design

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.
