How to use the Ask Advisor Router agent skill (ask)

Updated · written with AI from the project's own documentation and checked against our catalogue data

The Ask Advisor Router skill (ask) lets your AI agent send a question or task to another AI command-line tool installed on your machine, such as Codex, Gemini, Grok, Cursor or Muse, and save the answer as a markdown file. It is aimed at developers who already have several AI coding CLIs set up and want a second opinion, or a saved record of an advisor-style review. After this guide you will know what the skill does, how to install it, how to trigger it with a normal request, and what it needs to run.

Quick start

  1. 1Download and unzip. Download the skill ZIP from this page and unzip it into ~/.claude/skills/ or a project's .claude/skills/ folder.
  2. 2Or upload in the Claude apps. Open Settings, then Capabilities, then Skills, and upload the ZIP.
  3. 3Install omc and your provider CLIs. Make sure the omc wrapper and each provider CLI you want are installed and authenticated.
  4. 4Verify each CLI. Run the matching --version command, such as codex --version, for each provider you plan to use.
  5. 5Ask with a provider name. Request a provider and a question, for example using /oh-my-claudecode:ask codex followed by your question in quotes.
  6. 6Review the artifact. Open the markdown file saved under .omc/artifacts/ask/ to read the answer.

What the ask skill makes the agent do

An agent skill is a folder containing a SKILL.md file that gives an agent extra instructions for a specific job. This one, from the oh-my-claudecode toolkit, tells the agent to forward a prompt to one of the local Claude, Codex, Gemini, Antigravity, Grok, Cursor or Muse CLIs and persist the result as an ask artifact.

The skill tells the agent to use a wrapper command, omc ask, rather than calling those provider tools directly. The wrapper handles flag selection, artifact saving and provider-version compatibility.

Install the ask skill

Download the skill ZIP from this page and unzip it into one of two places. For a personal install that applies everywhere, use ~/.claude/skills/. For a single project, use the .claude/skills/ folder inside that project.

If you use the Claude apps instead, open Settings, then Capabilities, then Skills, and upload the ZIP there.

  • Personal install: ~/.claude/skills/
  • Project install: .claude/skills/ inside your project
  • Claude apps: Settings → Capabilities → Skills, then upload the ZIP

Check the required CLIs and the omc command

The skill needs the omc wrapper and at least one provider CLI that you have installed and authenticated. Check each one you plan to use with its version command. You only need the CLIs you actually intend to route to.

Antigravity (agy) is supported on macOS and Linux only. On Windows, use the gemini provider instead.

  • Provider accounts or API keys are required by each CLI as the provider specifies.
  • Muse and Grok must be versions that support --prompt-file.
claude --version codex --version gemini --version agy --version grok --version cursor-agent --version muse --version

Trigger the skill with a request

The skill's documented usage is a slash command with a provider name followed by your question or task. The provider must be one of claude, codex, gemini, antigravity, grok, cursor or muse. You can also ask in plain language and name the provider, and the agent will use the skill to run omc ask.

Muse accepts an --agent-prompt option, which the examples show with the critic role.

  • Codex: a security review of a patch
  • Gemini: UX suggestions for a flow
  • Claude: an implementation plan for an issue
  • Cursor: applying an implementation plan
  • Muse with the critic role: reviewing a plan
/oh-my-claudecode:ask codex "review this patch from a security perspective" /oh-my-claudecode:ask gemini "suggest UX improvements for this flow" /oh-my-claudecode:ask claude "draft an implementation plan for issue #123" /oh-my-claudecode:ask muse --agent-prompt critic "review this plan"

Find your saved answers

Each run writes a markdown file so you can review the answer later. Files are saved under the .omc/artifacts/ask folder, named with the provider, a slug of the request and a timestamp.

.omc/artifacts/ask/<provider>-<slug>-<timestamp>.md

Safety: scripts and network access

This skill runs scripts and uses the network. Your prompt is sent to the third-party provider you choose, so do not send sensitive code or private data unless that provider is acceptable for it. The wrapper writes prompts to private temporary files, including role files with YAML frontmatter. Muse runs with approvals disabled and keeps its configured sandbox behaviour.

Read the skill's SKILL.md and any installer before running it. The skill's own instructions say to inspect the Antigravity installer before running it.

  • Prompts leave your machine through the provider services.
  • Muse runs with approvals disabled; its sandbox setting is preserved.
  • Antigravity installer should be inspected before running.

What people use it for

  • Asking Codex to review a patch from a security angle before you merge it.
  • Getting UX suggestions for a user flow from Gemini or Antigravity.
  • Drafting an implementation plan with Claude and handing it to Cursor to apply.
  • Having Muse review a plan using the critic role.
  • Keeping a dated, saved record of advisor-style reviews for a team.

Frequently asked questions

How do I install the ask skill?

Download the skill ZIP from this page and unzip it into ~/.claude/skills/ for a personal install or into .claude/skills/ inside a project. In the Claude apps, open Settings, then Capabilities, then Skills, and upload the ZIP.

What do I need to run the ask skill?

You need the omc wrapper and the local CLI for each provider you use: claude, codex, gemini, agy, grok, cursor-agent or muse. Each must be installed and authenticated, and each provider may need an account or API key. Muse and Grok must support --prompt-file.

Is the ask skill free?

The source does not state pricing or licence terms beyond the listed licence, which is MIT. Provider CLIs may have their own costs or account requirements, which the source does not detail.

Why does it fail on Windows with Antigravity?

The skill's own notes say omc ask antigravity is supported on macOS and Linux only. On Windows it is guarded with an error, so use omc ask gemini instead.

Can I use the ask skill without any other tools installed?

No. The skill cannot work without the listed CLIs installed and logged in, so it is not suited to a fully self-contained setup.

Where do the saved answers go?

They are written to .omc/artifacts/ask/ as markdown files named with the provider, a slug and a timestamp.

Our verdict

Choose the ask skill if you already run several AI coding CLIs and want consistent routing to a second model, with each answer saved for later review. Pick something else if you do not have those CLIs set up, or if your code or data must stay on your own machine, because prompts are sent to third-party providers.
