sandbox-triage skillA
sandbox-triage is agent-read markdown (skill) from miosa-osa/osa: Triage suspicious files with static metadata and bounded scanning, and distinguish malware detonation from safe application attack labs. Use for sandbox triage, suspicious attachments, YARA scanning or malware analysis preparation..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Sandbox Triage ## Workflow 1. Identify whether the request is static sample triage, malware detonation, or an OSA application simulation. They require different isolation. 2. Preserve hashes and custody; treat filenames, archives and parser outputs as untrusted input. 3. Read the static workflow. Do not execute samples, enable macros, upload confidential samples or use untrusted compiled YARA rules. 4. Bound scanner time and input size; scan trusted source-form rules with benign and matching fixtures. An empty match set is inconclusive. 5. Actual malware detonation requires a separately provisioned disposable VM, isolated network, no host shares/credentials and monitoring. This skill does not provision or claim such a VM. 6. Report static indicators and confidence separately from observed behavior. OSA cyber_defense runs only fixed application fixtures and is not a malware sandbox. ## Worked example and prerequisites …

How to install
mdr add miosa-osa/osa/sandbox-triage@v1.0.200mdr add miosa-osa/osa/sandbox-triage@sha256:abd4fd6fe16d5d38Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
