aegis-service-sandboxing SKILL.md skillB
aegis-service-sandboxing from as-foss/aegis-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Audit Linux service and process containment covering root-running units, systemd sandboxing directives, MAC system status, container escape surfaces, and root-writable cron chains.
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
## Scope & Objectives Audit containment of long-running services and scheduled jobs on a single Linux host or its config-as-code repository. Determine: 1. Which services execute with root identity or with identities that are shared, reusable, or login-capable. 2. Whether systemd units apply the sandboxing directives that cost nothing at design time and remove entire exploit classes (CWE-250: Execution with Unnecessary Privileges). 3. Whether SELinux or AppArmor is present, and in which mode. 4. Whether container runtime configuration grants host-equivalent power (docker.sock mounts, `--privileged`, `--network host`, `--pid host`, added capabilities). 5. Whether root-owned cron/timer scripts can be modified by unprivileged principals. Constraints for the executing agent: - Run only non-mutating commands: read files, list processes, inspect units, query container metadata. Do not edit unit files, do not restart services, do not enter containers. - Service restarts require orchestrator-approved change windows. Propose them; never perform them during the audit. …

How to install
mdr add as-foss/aegis-skills/aegis-service-sandboxing@sha256:8582b8c352208d36The line at the top of this page pins the label git:20260826.9702747, 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.
