No install command here reaches Kiro. Copy the skill's folder into .kiro/skills/ in your project, or ~/.kiro/skills/ for all your projects. NVIDIA/OpenShell/crates/openshell-supervisor-process/src/skills/policy-advisor (opens in a new tab)

Pattern check
Pattern check: nothing flagged · commit 42671c2 · 1 Nov 2026
We checked every text file in this skill, at commit 42671c2 on 1 Nov 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

Outside links we did not follow
- http://policy.local/v1/policy/current
- http://policy.local/v1/proposals
Format check
Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.
Agent Skills specFails
The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.
- Error
The name "openshell-policy-advisor" doesn't match its folder "policy-advisor". The spec requires them to match. N4
Fix: Set name: policy-advisor, or rename the folder to openshell-policy-advisor.
- Note
There is no license field, so readers can't tell whether they may reuse the skill. O2
Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.
- Error
Claude CodePasses
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.
- Note
The name "openshell-policy-advisor" doesn't match its folder "policy-advisor". Claude Code shows the skill as /openshell-policy-advisor, and the folder name also invokes it. N4
Fix: Set name: policy-advisor, or rename the folder to openshell-policy-advisor.
- Note
Claude apps & API uploadFails
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Error
The name "openshell-policy-advisor" doesn't match its folder "policy-advisor". claude.ai refuses an upload whose folder name doesn't match the skill name. N4
Fix: Set name: policy-advisor, or rename the folder to openshell-policy-advisor.
- Error
OpenAI (Codex & API)Passes with warnings
Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.
- Warning
The name "openshell-policy-advisor" doesn't match its folder "policy-advisor". OpenAI's own upload example uses a differently named folder, but the spec it follows says they must match. N4
Fix: Set name: policy-advisor, or rename the folder to openshell-policy-advisor.
- Warning
VS Code & CopilotPasses with warnings
VS Code reads skills one folder below .github/skills, .claude/skills or .agents/skills and falls back to the folder name when the name is missing or differs; GitHub's Copilot docs require the exact name SKILL.md.
- Warning
The name "openshell-policy-advisor" doesn't match its folder "policy-advisor". VS Code uses the folder name, policy-advisor, instead. N4
Fix: Set name: policy-advisor, or rename the folder to openshell-policy-advisor.
