At a glance

A skill your agent uses when an OpenShell sandbox returns policydenied, mentions policy.local, or needs a narrow network policy proposal.

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Mentions policy.local
  • Needs a narrow network policy proposal

What it does

Openshell Policy Advisor is an agent skill from NVIDIA/OpenShell, published by the product's own GitHub organization. Use when an OpenShell sandbox returns policydenied, mentions policy.local, or needs a narrow network policy proposal.

Its SKILL.md is about 150 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Sales & Support. The repository describes itself as: OpenShell is the safe, private runtime for autonomous AI agents. The licence is Apache-2.0.

When your agent uses it

  • An OpenShell sandbox returns policydenied
  • Mentions policy.local
  • Needs a narrow network policy proposal

Example prompts

  • “/openshell-policy-advisor”

What it can do on your machine

Read from SKILL.md and the folder at commit 834b79a. 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

Openshell Policy Advisor loads about 150 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 45 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~150

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.

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.
