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 | $0.00052 | $0.00652 |
| Opus 5 | $0.00026 | $0.00326 |
| Sonnet 5 | $0.00010 | $0.00130 |
| Haiku 4.5 | $0.00005 | $0.00065 |
Grade A, and why
protect-nebius-infra-details 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 12d 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 — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Protect Nebius Infra Details
Keep concrete live resource identifiers and names, account or tenant details, private endpoints and object/registry URIs, and credentials out of Git and public collaboration surfaces. Apply the rule even when a value is not itself a secret.
Verified agent UI endpoint exception
The canonical https://<public_ip>/ for an NPA agent may be included in local
operator output or an explicitly requested operational handoff, including a PR
handoff, only when all of these are true at disclosure time:
npa agent statusreportsendpoint_disclosure_allowed=trueandbasic_auth_enforced=true.- The authenticated UI probe succeeded and the unauthenticated root probe
returned
401. - The URL contains no username, password, query, or fragment.
- The operator explicitly requested the endpoint for the agent in scope.
This exception does not permit direct_url, usernames, passwords, auth-file
contents, project/tenant/cluster/bucket identifiers, or unrelated endpoints.
Never copy the endpoint into committed source, docs, examples, tests, fixtures,
or reusable configuration. If the proof is missing or stale, keep the endpoint
in access-controlled evidence and withhold it from the handoff.
Publication workflow
-
Treat commits, docs, reports, examples, fixtures, tests, PR or issue text, and live-validation handoffs as publication surfaces.
-
Store exact operational evidence only in access-controlled external artifacts. In repository summaries, use generic resource roles plus non-identifying counts, timings, measurements, and cryptographic hashes.
-
Do not copy task-scoped consent, resource inventories, private locations, or teardown identifiers into reusable configs. State the requirement and point to externally retained evidence without naming its location.
-
Scan staged content before committing:
git diff --cached --no-ext-diff | \ npa/.venv/bin/python -m npa.guardrails.confidentiality \ --built-in-nebius-infra --stdin-source staged-diff --stdin-is-diff
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

protect-nebius-infra-details is a skill published in the GitHub repository nebius/nebius-physical-ai (29 stars, last pushed today), licensed Apache-2.0. It adds 52 tokens to every session and 652 once invoked, about $0.0003 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.
