openshell-policy-advisor

openshell-policy-advisor is a skill for Claude Code, Codex from NVIDIA/OpenShell. It costs 29 tokens per session (139 once invoked), scanned A, original, Apache-2.0.

A guide for handling OpenShell sandbox requests that are blocked by a network policy. It helps prepare a narrow request to allow the needed connection.

In plain words
What is it for?
Investigating `policy_denied` errors, reviewing `policy.local`, and proposing limited network access for an OpenShell sandbox.
Why use it?
A sandbox may deny a network request even when the task still requires it. This defines a process for checking the policy, requesting an exception, and retrying after approval.

Token cost

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.

Security

Grade A, and why

openshell-policy-advisor 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 2mo 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.

What it actually says

OpenShell Policy Advisor

When a request fails with policy_denied, do not treat the denial as final if the user task still needs the request. Read /etc/openshell/skills/policy_advisor.md, inspect http://policy.local/v1/policy/current, submit the narrowest proposal to http://policy.local/v1/proposals, wait on /v1/proposals/{chunk_id}/wait?timeout=300, and retry only after approval with policy_reloaded: true.

Changes

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.
