What is shellink-cli?

A skill for using the local Shellink command-line tool to open SSH or command sessions, run remote commands, transfer files, and use saved connection profiles.

Remote server administration, command execution, interactive terminal work, file transfers, and managing connection profiles.

It gives the coding agent a defined way to work with remote machines and interactive terminals. Shellink must be installed and available on the system PATH.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/jie123108/Shellink

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00049	$0.00764
Opus 5.5	$0.00020	$0.00306
Sonnet 5.5	$0.00010	$0.00153
Haiku 4.5	$0.00005	$0.00076

Security

Grade A, and why

shellink-cli scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Shellink CLI

This skill depends on the local shellink command. Do not implement or connect to the Unix socket protocol directly.

Prerequisite: install `shellink` if missing

Before any Shellink operation, ensure shellink is available:

command -v shellink

If it is missing:

macOS / Linux — install the prebuilt binary (latest release):

curl -fsSL https://raw.githubusercontent.com/jie123108/Shellink/main/install.sh -o /tmp/shellink-install.sh
cat /tmp/shellink-install.sh
sh /tmp/shellink-install.sh

Pin a version if needed:

curl -fsSL https://raw.githubusercontent.com/jie123108/Shellink/main/install.sh -o /tmp/shellink-install.sh
cat /tmp/shellink-install.sh
sh /tmp/shellink-install.sh --version v0.1.0

The installer places shellink in $HOME/.local/bin. If that directory is not on PATH, add it for the current session (and tell the user to persist it in their shell profile):

export PATH="$HOME/.local/bin:$PATH"

Windows — prebuilt binaries are not published. Tell the user to build from source (Node.js 22.19+, npm):

git clone https://github.com/jie123108/Shellink.git
cd Shellink
npm install
npm run build
# CLI: ./node_modules/.bin/shellink

After install, verify:

shellink -V
shellink server status --json

To upgrade an existing standalone binary:

shellink upgrade --check --json
shellink upgrade --yes --json

npx skills update shellink-cli only updates this skill, not the shellink binary.

Operate sessions

Always read the installed command reference before operating sessions or profiles, and follow it. Re-read it rather than relying on memorized commands:

shellink agent-doc

Add --json for stable machine-readable output. A command starts the user daemon automatically.

Long-running operations

Host agents (e.g. Cursor) wait only ~30s for a shell command before backgrounding it. Keep every CLI call short: for anything that may exceed ~25s, use --detach and poll the returned job.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
