firmware-analysis

firmware-analysis is a skill for Claude Code, Codex from MineRoma/nekocode. It costs 3 tokens per session (867 once invoked), scanned A, original, GPL-3.0.

A tool for extracting and examining code from embedded firmware and bare-metal programs, which run directly on hardware without a full operating system.

In plain words
What is it for?
Use it to inspect firmware images, understand low-level hardware code, and investigate how embedded devices work.
Why use it?
It helps when analyzing device software where the original source code or normal debugging tools are unavailable.

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

firmware-analysis 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 6d 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.

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.

firmware-analysis is a skill published in the GitHub repository MineRoma/nekocode (5 stars, last pushed 16d ago), licensed GPL-3.0. It adds 3 tokens to every session and 867 once invoked, about $0.0000 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 2026-08-31.
