## What it does

The skill covers host selection through the OpenRig registry and the differences between SSH and HTTP routes. It discusses commands such as `rig host list`, `rig send`, `rig capture`, `rig ps`, and `rig whoami`, along with failures at different stages. For consequential work, it directs you to check the specific command’s help and the target host’s state.

SSH runs a remote CLI command through a shell; HTTP talks to the remote daemon. OpenRig does not switch routes automatically when one fails. An HTTP registry entry needs a URL and can use `bearer_env` or `bearer_file` for credentials. A timed-out write may already have reached the host, so inspect its effect before sending it again.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill cross-host-rig-commands -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/cross-host-rig-commands/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/cross-host-rig-commands/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill cross-host-rig-commands -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/cross-host-rig-commands/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill cross-host-rig-commands -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/cross-host-rig-commands/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mvschwarz/openrig cross-host-rig-commands
```

2. **Manually: put the files in place**
- File: `.github/skills/cross-host-rig-commands/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill cross-host-rig-commands -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mvschwarz/openrig --path skills/_canonical/core/cross-host-rig-commands
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/cross-host-rig-commands/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mvschwarz/openrig --skill cross-host-rig-commands -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mvschwarz/openrig/tree/HEAD/skills/_canonical/core/cross-host-rig-commands/SKILL.md

## When to use it
- choose a registered host and check its reachability
- identify whether an SSH or HTTP route failed
- check whether a remote command took effect after a timeout
- distinguish command transport success from confirmation of the remote operation

## Example prompts
- Check which transport is configured for `remote-dev` and explain what to verify before running a remote command.
- Review the result of `rig send` to `remote-dev` and tell me how to check whether it arrived.
- Explain the difference between an SSH connection failure and a failed remote OpenRig command.

# Cross-host rig commands

Use a registered host address and the entry's declared transport. SSH entries
run a remote CLI through a single-hop shell; HTTP entries use the remote daemon.
These paths have different prerequisites and command coverage. Check the exact
command's help and the target installation before a consequential operation.

## Choose and inspect the destination

`rig host list` shows registered hosts. `rig host add --help` describes registry
writes; `rig host doctor --help` describes reachability checks. Inspect the
configured OpenRig home rather than assuming the default `~/.openrig/hosts.yaml`.
Registry changes affect later routing, so make them within the requested scope.

```yaml
hosts:
  - id: test-vm
    transport: ssh
    target: test-vm.local
    user: example-user
  - id: remote-dev
    transport: http
    url: http://remote-dev.example:7433
    bearer_env: REMOTE_RIG_TOKEN
```

The registry requires a hosts array, unique non-empty ids and a supported
transport. SSH needs a non-empty target; user and notes are optional. HTTP needs
a URL and accepts at most one of bearer_env or bearer_file. Omitting both is
valid for a tokenless target. A configured but unavailable bearer is a permission
failure, not anonymous fallback. Host ids also have reserved-name validation;
use the actual validator's error rather than inventing an alias that collides.

## Address the intended operation

```bash
rig send dev-worker@example-rig "check the assigned result" --host remote-dev --verify
rig capture dev-worker@example-rig --host remote-dev
rig ps --host remote-dev --nodes --json
rig whoami --host remote-dev
```

These coordination commands select SSH or HTTP from the registry entry. They
do not silently try another transport when one fails. A host-qualified target
can be convenient, but confirm its parsing and any persisted host selection
with the particular command. Explicit --host is preferable for consequential
cross-host work.

Queue destinations use explicit --host or a supported host-qualified destination;
queue writes do not follow persisted host selection. The CLI separates the host
