SSH Remote Access
Overview
SSH (Secure Shell) provides encrypted remote access, file transfer, and tunneling over untrusted networks. OpenSSH is the standard implementation on Linux, macOS, and Windows (via built-in client). The client configuration lives at ~/.ssh/config and supports per-host settings, identity management, and connection reuse.
When to use: Remote server management, secure file transfers, port forwarding, jump host traversal, automated deployments, SOCKS proxying.
When NOT to use: High-throughput bulk data transfer across WANs (use Globus or similar), GUI-heavy remote desktop (use VNC/RDP), container orchestration (use kubectl/docker CLI).
Quick Reference
| Pattern | Command / Directive | Key Points |
|---|---|---|
| Basic connect | ssh user@host | Add -p PORT for non-default port |
| Identity file | ssh -i ~/.ssh/key user@host | Specify private key explicitly |
| Remote command | ssh user@host "command" | Add -t for interactive commands |
| SSH config alias | Host myserver block in ~/.ssh/config | Simplifies repeated connections |
| File copy (rsync) | rsync -avzP src user@host:dest | Preferred over scp for all transfers |
| File copy (scp) | scp file user@host:path | Legacy protocol; uses SFTP internally |
| Local tunnel | ssh -L local:remote_host:remote_port | Access remote services locally |
| Remote tunnel | ssh -R remote:localhost:local_port | Expose local services to remote |
| SOCKS proxy | ssh -D 1080 user@host | Dynamic port forwarding |
| Jump host | ssh -J jump user@target | ProxyJump, available since OpenSSH 7.3 |
| Key generation | ssh-keygen -t ed25519 | Ed25519 recommended for all new keys |
| FIDO2 key | ssh-keygen -t ed25519-sk | Hardware-backed, requires OpenSSH 8.2+ |
| Agent | ssh-add ~/.ssh/key | Cache key passphrase for session |
| Multiplexing | ControlMaster auto in config | Reuse TCP connections across sessions |
| Debug | ssh -v user@host | Up to -vvv for maximum verbosity |
Key Type Recommendations
| Algorithm | Recommendation | Notes |
|---|---|---|
| Ed25519 | Default for all new keys | 256-bit, fast, secure, supported on OpenSSH 6.5+ |
| Ed25519-SK (FIDO2) | Strongest option with hardware key | Requires physical security key, OpenSSH 8.2+ |
| RSA 4096 | Legacy compatibility only | Use only when Ed25519 is unsupported by the remote system |
| ECDSA | Avoid | Implementation concerns; prefer Ed25519 |
File Transfer Decision Guide
| Scenario | Tool | Why |
|---|---|---|
| Recurring syncs or large directories | rsync -avzP | Delta sync, compression, resume, progress |
| Quick one-off file copy | scp or rsync | scp is simpler; rsync is more capable |
| Interactive file browsing | sftp | Tab completion, directory navigation |
| High-bandwidth WAN transfers | Specialized tools (Globus) | SSH buffer limits reduce WAN throughput |
Common Mistakes
| Mistake | Correct Pattern |
|---|---|
| Using RSA keys for new setups | Generate Ed25519 keys -- faster, smaller, and equally secure |
Using scp for large or recurring transfers | Use rsync -avzP for compression, progress, and resumable delta sync |
| Typing passphrase repeatedly during sessions | Use ssh-agent and ssh-add to cache keys for the session |
| Connecting through multiple hops with nested SSH | Use -J (ProxyJump) for clean bastion/jump host traversal |
Running interactive commands without -t flag | Use ssh -t user@host "htop" to allocate a pseudo-terminal |
Using ForwardAgent yes through untrusted hosts | Use ProxyJump instead -- agent forwarding exposes keys to compromised hosts |
Setting ControlPath without %h, %p, %r | Include all three tokens to ensure unique sockets per connection |
| Disabling host key checking globally | Only use StrictHostKeyChecking no in trusted, ephemeral environments |
Not using IdentitiesOnly yes | Prevents offering every loaded key to every server |

FAQ
What does the ssh-remote skill do?
SSH remote access patterns and secure shell utilities. Covers connections, config management, key generation (Ed25519, FIDO2), tunneling, port forwarding, file transfers, and multiplexing. Use when connecting to servers, managing SSH keys, setting up tunnels, transferring files over SSH, configuring jump hosts, or hardening SSH access.
How do I install ssh-remote?
Run npx skills add https://github.com/oakoss/agent-skills --skill ssh-remote in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/ssh-remote/ (personal) or .claude/skills/ssh-remote/ (project).
Which AI agents can use ssh-remote?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is ssh-remote safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains ssh-remote?
It is published by oakoss in oakoss/agent-skills. It has 170 recorded installs.

codex-pet
prime-skills/runcomfy-agent-skills
Codex Pet generator on RunComfy. Build a Codex-compatible Codex Pet spritesheet.webp + pet.json from a single reference image, drop it into ${CODEXHOME:-$HOME/.codex}/pets/ / and Codex picks it up as a custom Codex Pet next to the 8 built-ins. This skill produces the exact Codex Pet atlas Codex expects (1536x1872 PNG/WebP, 8 cols x 9 rows, 192x208 cells, 9 animation states — idle, running-right, running-left, waving, jumping, failed, waiting, running, review). Calls OpenAI GPT Image 2 edit ONCE via the local RunComfy CLI as runcomfy run openai/gpt-image-2/edit to produce a canonical Codex Pet pose, then assembles all 9 animation rows programmatically with ImageMagick micro-transforms — no Codex Pro, no $imagegen, no OPENAIAPIKEY required, only RUNCOMFYTOKEN. Triggers on "codex pet", "create codex pet", "make codex pet", "hatch codex pet", "/hatch image", "desktop pet codex", "codex pets", "spritesheet.webp", or any explicit ask to build a custom pet for OpenAI Codex.
