Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for firmware images, partition tables, boot chains, update packages, extracted filesystems, embedded configs, and device-facing trust boundaries. Use when the user asks to unpack firmware, map partition layout, inspect bootloader or init chains, recover update keys or credentials, trace config loading, or explain how a device surface reaches the decisive artifact. Use only after `$ctf-sandbox-orchestrator` has already…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Competition Firmware Layout Use this skill only as a downstream specialization after `$ctf-sandbox-orchestrator` is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to `$ctf-sandbox-orchestrator` first. Use this skill when the hard part is understanding how a firmware image is structured, booted, updated, and turned into reachable device behavior. Reply in Simplified Chinese unless the user explicitly requests English. ## Quick Start 1. Preserve the original image, extracted partitions, unpacked filesystems, and patched copies as separate artifacts. 2. Map outer container, partition table, bootloader, kernel, rootfs, config, and update metadata before editing anything. 3. Track the boot or update chain in order instead of jumping straight to the most interesting file. 4. Record keys, signatures, offsets, partition boundaries, and init entrypoints in one compact evidence chain. 5. Reproduce the decisive secret, branch, or reachable service from the smallest extracted path. ## Workflow ### 1. Establish Image Layout …

How to install
mdr add novaestellar/novahaku/competition-firmware-layout@sha256:aab2dcbaedec7250The line at the top of this page pins the label git:20260925.9330cc6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
