Audit Embedded Firmware Security is an agent skill from cyberful/cyberful. Audit extracted embedded firmware for boot and update trust, credential and secret handling, service exposure, privilege boundaries, parsers, persistence, cryptography, hardening, recovery, and product-specific security invariants. Use for static firmware evidence after safe acquisition and extraction.
Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files and assets (for example `agents/openai.yaml`, `assets/firmware-trust-ledger.template.json` and `references/firmware-audit-method.md`).
It sits in Security, covering Cryptography. The repository describes itself as: Cyberful is an open-source AI Red Team for discovering, exploiting, verifying, and remediating vulnerabilities. The licence is AGPL-3.0.
Read from SKILL.md and the folder at commit ec598a6. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Audit Embedded Firmware Security loads about 644 tokens when it runs, and up to ~924 if it reads all its reference files. Until then it costs about 84 tokens; SKILL.md has 200 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/audit-embedded-firmware-security/SKILL.md (or your agent's skills folder). This skill also uses 3 other files; get the full folder from GitHub.Audit the extracted artifact as evidence tied to a device, version, acquisition path, and extraction manifest. Do not execute an extracted init system or treat strings and filenames as proof of reachable behavior.
Record image hash, product and hardware claims, partitions, filesystems, architecture, boot artifacts, signing and verification metadata, update format, rollback controls, recovery images, build identifiers, packages, native hardening, and extraction limitations.
Copy assets/firmware-trust-ledger.template.json into the workarea. Read references/firmware-audit-method.md before connecting an extracted component to boot, update, service, or persistence behavior.
Map startup and privilege transitions, users and groups, service listeners, IPC, parsers, web routes, update and provisioning code, credentials, keys, certificates, debug paths, logging, storage, firewall rules, kernel and module configuration, and recovery behavior. Trace candidates into code and configuration rather than reporting inventory alone.
Use operate-firmware-laboratory for import, extraction, comparison, emulation, and managed tool operation. Route whole-product and lifecycle risk to assess-embedded-iot-security; this skill owns static firmware audit reasoning.
Tie every candidate to artifact hashes, paths, startup or call reachability, attacker position, privilege or identity, device state, fleet reuse, control comparison, and a bounded validation plan. Mark extraction ambiguity and version-to-device uncertainty explicitly.

Audit extracted embedded firmware for boot and update trust, credential and secret handling, service exposure, privilege boundaries, parsers, persistence, cryptography, hardening, recovery, and…. Audit Embedded Firmware Security is an agent skill from cyberful/cyberful. Audit extracted embedded firmware for boot and update trust, credential and secret handling, service exposure, privilege boundaries, parsers, persistence, cryptography, hardening, recovery, and product-specific security invariants.
Audit Embedded Firmware Security fits situations like: static firmware evidence after safe acquisition and extraction; tasks that involve Cryptography.
Run `npx skills add cyberful/cyberful --skill audit-embedded-firmware-security -a claude-code`. Or copy the skill folder (cyberful/builtin/skills/audit-embedded-firmware-security in cyberful/cyberful) into .claude/skills/audit-embedded-firmware-security in your project. Claude Code loads it when a task matches its description.
Run `npx skills add cyberful/cyberful --skill audit-embedded-firmware-security -a codex`. Or copy the skill folder (cyberful/builtin/skills/audit-embedded-firmware-security in cyberful/cyberful) into .agents/skills/audit-embedded-firmware-security in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add cyberful/cyberful --skill audit-embedded-firmware-security -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/audit-embedded-firmware-security, .gemini/skills/audit-embedded-firmware-security, .github/skills/audit-embedded-firmware-security and .opencode/skills/audit-embedded-firmware-security in your project.
SKILL.md names no scripts, command-line tools or credentials: Audit Embedded Firmware Security is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Audit Embedded Firmware Security is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 644 tokens (SKILL.md is roughly 2.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 280 tokens, read only when the agent opens those files.
