StarAgent: Skill for Claude Code

.agents/staragent-use/SKILL.md

staragent-use is a skill for Claude Code, Codex from SiriusNEO/StarAgent. It costs 0 tokens per session (1,428 once invoked), scanned B, original, MIT.

A guide for operating StarAgent, a dashboard for long-running coding sessions running inside tmux, a terminal tool that keeps sessions alive.

In plain words
What is it for?
Use it to start the Hub or Nodes, create and attach to agent sessions, manage tmux sessions, and inspect runtime connectivity.
Why use it?
It explains how the dashboard, machines, terminals, and coding sessions relate, making it easier to start them and diagnose connection problems.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions Claude Code; installed under .agents/ (shared by several agents); mentions Codex.

This is SiriusNEO/StarAgent's own configuration. It tells Claude Code and Codex how to work on StarAgent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything StarAgent configures →

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.

Security

Grade B, and why

staragent-use scanned grade B with 2 findings 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 8d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

StarAgent Use

StarAgent is a tmux-first dashboard for long-lived coding CLI sessions. Live tmux sessions are the source of truth. The web dashboard, Chat, Terminal, and file views are projections over real tmux state.

Concepts

  • Hub: the web dashboard and coordinator. It also acts as the local node.
  • Node: a machine that owns tmux sessions and exposes them through the StarAgent node API.
  • Agent session: a tmux session running Codex, Claude Code, Gemini, OpenCode, or shell.
  • System session: infrastructure tmux session such as staragent-hub, staragent-node, or staragent-tailscaled.
  • Terminal: live tmux PTY view and ground-truth display.
  • Chat: mobile-friendly structured view derived from the tmux transcript.

Reserve agent for coding CLIs. Use node for infrastructure hosts.

Runtime State

Project-local state should live in .staragent/ by default.

Important environment variables:

  • STARAGENT_AUTH_TOKEN: dashboard auth token for the Hub.
  • STARAGENT_NODE_TOKEN: shared token used by remote nodes.
  • STARAGENT_STATE_DIR: optional runtime state directory override.

Start StarAgent

Install:

pip install -e '.[dev]'

Start the Hub:

staragent hub --host 0.0.0.0 --port 8080

staragent hub creates the staragent-hub tmux system session by default.

Start a remote Node:

export STARAGENT_NODE_TOKEN="<same token as the Hub>"
sudo tailscale up --ssh
staragent node-ts --sudo

staragent node-ts checks for Tailscale and confirms it is connected, then starts the staragent-node tmux system session and configures tailscale serve. If Tailscale is missing or not connected, it must print the tailscale up --ssh command to run first and stop before creating the Node tmux session.

Use staragent node instead when LAN or another network layer already exposes the Node. Add the node endpoint from the dashboard Nodes page after it is reachable from the Hub.

Sessions

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.

staragent-use is a skill published in the GitHub repository SiriusNEO/StarAgent (59 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,428 tokens. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
