Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00014 | $0.02260 |
| Opus 5 | $0.00007 | $0.01130 |
| Sonnet 5 | $0.00003 | $0.00452 |
| Haiku 4.5 | $0.00001 | $0.00226 |
Grade D, and why
fabric-containers scanned grade D with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
n.execute('sudo ssh-keygen -t rsa -N "" -f /root/.ssh/id_rsa', quiet=True) Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
n.execute('ssh-keygen -t rsa -N "" -f /home/ubuntu/.ssh/id_rsa', quiet=True) How it starts
The opening of the file, as written. The whole thing — 323 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Instructions
When invoked, generate code for container-based workloads on FABRIC. Two main capabilities:
- Docker — Container deployment using post-boot scripts or runtime commands
- Kubernetes — Multi-node K8s cluster with Flannel CNI across FABRIC sites
Help the user choose the right approach and generate complete setup code.
API Reference
Docker Images
FABRIC provides Docker-ready OS images:
docker_rocky_8— Rocky Linux 8 with Docker pre-configureddocker_ubuntu_20— Ubuntu 20.04 with Docker pre-configured
Post-Boot Docker Setup
node.add_post_boot_upload_directory('node_tools', '.')
node.add_post_boot_execute('node_tools/enable_docker.sh {{ _self_.image }}')
Post-Boot Docker Compose
node.add_post_boot_upload_directory('docker_containers', '.')
node.add_post_boot_execute('cd docker_containers/my_app ; docker compose up -d')
Patterns
Docker Container Deployment
from fabrictestbed_extensions.fablib.fablib import FablibManager
fablib = FablibManager()
slice = fablib.new_slice(name="docker-experiment")
node = slice.add_node(
name="docker-node",
site=fablib.get_random_site(),
cores=4,
ram=16,
disk=100,
image="docker_rocky_8",
)
node.add_fabnet()
# Enable Docker via post-boot
node.add_post_boot_upload_directory('node_tools', '.')
node.add_post_boot_execute('node_tools/enable_docker.sh {{ _self_.image }}')
slice.submit()
# Run a container
node = slice.get_node(name="docker-node")
stdout, stderr = node.execute(
"docker run -d -it "
"--name my_container "
"fabrictestbed/slice-vm-rocky8-multitool:0.0.1"
)
# View containers
stdout, stderr = node.execute("docker ps -a")
print(stdout)
# Execute commands in container
stdout, stderr = node.execute("docker exec my_container ip addr list")
print(stdout)
Docker Compose via Post-Boot
slice = fablib.new_slice(name="compose-experiment")
node = slice.add_node(
name="app-node",
site=fablib.get_random_site(),
cores=4,
ram=16,
disk=100,
image="docker_rocky_8",
)
# Upload and start Docker + application
node.add_post_boot_upload_directory('node_tools', '.')
node.add_post_boot_execute('node_tools/enable_docker.sh {{ _self_.image }}')
node.add_post_boot_upload_directory('docker_containers', '.')
node.add_post_boot_execute('cd docker_containers/my_app ; docker compose up -d')
slice.submit()
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

fabric-containers is a skill published in the GitHub repository fabric-testbed/claude-plugin-marketplace (2 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 14 tokens to every session and 2,260 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
