Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
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 | $0.00028 | $0.01115 |
| Opus 5 | $0.00014 | $0.00558 |
| Sonnet 5 | $0.00006 | $0.00223 |
| Haiku 4.5 | $0.00003 | $0.00112 |
Grade A, and why
fiftyone scanned grade A with 0 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 2d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
FiftyOne
The PAIDF worker image remains contract-attested and non-root for SkyPilot
0.12.2, with passwordless sudo, SSH/rsync/service prerequisites, writable paths,
and a forwarding entrypoint. Submit the verified immutable digest; never use a
runAsUser: 0 workflow override.
FiftyOne is the dataset curation and visualization tool. It is CPU-only and does not require a GPU.

npa workbench fiftyone open maintains a verified SSH tunnel for a VM or
kubectl port-forward for Kubernetes; callers should not need raw tunnel commands.
Deployment And Access
The App is an operator interface with access to service-readable files. Bind it
to 127.0.0.1 and access it through authenticated SSH or Kubernetes port-forward.
--public-ip, non-loopback --address, and application ingress are rejected.
Kubernetes uses a ClusterIP Service only as a port-forward target; the pod's App
and its exec readiness check use loopback. Keep Kubernetes port-forward RBAC
limited to authorized operators. CORS does not provide authentication.
Stock FiftyOne App has no /health endpoint: GET / returns 200 and GET /health returns 307.
Managed VM deploy defaults to in-place updates for existing aliases. Terraform
plans that would destroy or replace critical infrastructure are blocked unless
the operator passes --replace and confirms with --yes for automation.
VM and BYOVM deploys record endpoint_strategy: ssh_fallback. Live status and
GraphQL requests always create a fresh SSH forward with verified host keys,
including for older aliases that recorded a public endpoint. Launch and dataset
loading run over SSH. Use open to keep a browser tunnel alive. Unknown or
changed SSH host keys fail closed; provide an independently verified
NPA_SSH_KNOWN_HOSTS file for a BYOVM host without a provider pin.
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.

fiftyone is a skill published in the GitHub repository nebius/nebius-physical-ai (27 stars, last pushed today), licensed Apache-2.0. It adds 28 tokens to every session and 1,115 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
