What it does
Audit Container Runtime Isolation is an agent skill from cyberful/cyberful. Audit container runtime isolation across namespaces, capabilities, seccomp, mandatory access control, mounts, devices, daemon sockets, cgroups, identity, and host integration. Use for container configuration or runtime-boundary review.
Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files and assets (for example `agents/openai.yaml`, `assets/container-isolation-matrix.example.json` and `assets/container-isolation-matrix.schema.json`).
It sits in Security, covering Authorization and RBAC. 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.
When your agent uses it
- Container configuration
- Runtime-boundary review
Example prompts
- “/audit-container-runtime-isolation”
What it can do on your machine
Read from SKILL.md and the folder at commit ec598a6. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
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.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Audit Container Runtime Isolation loads about 545 tokens when it runs, and up to ~826 if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 143 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.
Safety
Auto-check passed
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.

Audit Container Runtime Isolation
Evaluate the effective host boundary, not the image alone. Start with the runtime, kernel, workload configuration, orchestrator mutations, node placement, and host integrations that determine what the container can reach.
Build the boundary matrix
Read references/container-isolation-method.md. Populate assets/container-isolation-matrix.example.json using assets/container-isolation-matrix.schema.json. Record each isolation layer, effective setting, provenance, protected host resource, bypass precondition, and evidence.
Trace user and group mapping, privilege mode, capabilities, seccomp, AppArmor or SELinux, namespaces, cgroups, devices, mounts, proc/sys exposure, daemon and runtime sockets, host networking, kernel interfaces, runtime class, and node trust. Treat a missing hardening control as risk evidence; confirm exploitability only when a reachable primitive crosses a protected boundary.
Report precisely
Separate workload takeover, cross-container access, node-level effect, and cluster control-plane effect. Record the minimum attacker foothold, required kernel/runtime behavior, effective configuration, compensating controls, and a harmless verification path suitable for an isolated lab.
