skupper-linux-two-site

skupper-linux-two-site is a skill for Claude Code, Codex from rhtevan/agentfs. It costs 21 tokens per session (3,852 once invoked), scanned B, a copy of angular-conventions, Apache-2.0.

A workflow for connecting two Linux sites with a Skupper Virtual Application Network using native skrouterd and mutual TLS. The setup verifies the connection with netcat, a command-line network testing tool.

In plain words
What is it for?
Use it to create and test a two-site connection, supplying site names, an SSH host, a namespace, and optional firewall and test settings.
Why use it?
It provides a defined process for creating the sites, securing their link, and checking that traffic can pass between them.

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

skupper-linux-two-site scanned grade B 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 4d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/create-site.sh, scripts/link-sites.sh, scripts/teardown.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 442 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skupper V2 — Linux/systemd Two-Site Setup

Create a two-site Skupper Virtual Application Network (VAN) on the Linux/systemd platform using native skrouterd, link the sites with mTLS, and verify end-to-end connectivity using nc (netcat).

Parameters

Parameters are defined in the YAML frontmatter under parameters:. Each parameter has binding-cues — phrases the agent should match against user input for semantic binding.

Parameter Required Default Binding Cues Example
LOCAL_SITE_NAME "local site", "this host", "edge site" my-local
REMOTE_SITE_NAME "remote site", "hub site", "interior site" my-remote
REMOTE_SSH_HOST "ssh host", "remote host", "connect to" my-remote-host
NAMESPACE "namespace", "ns" playground
FIREWALL_ZONE auto-detect "firewall zone", "zone" FedoraWorkstation
TEST_PORT 9090 "test port", "port", "nc port" 9090
TEST_ROUTING_KEY nc-test "routing key", "service key" nc-test

Agent Binding Rules

  1. Match user input against binding-cues — when the user says "set up a skupper VAN to remote host my-remote-host", bind my-remote-host to REMOTE_SSH_HOST (matches "remote host").

  2. Prompt for missing required parameters — if a required parameter cannot be resolved from context, present a usage hint:

    Missing required parameters. Usage:
      skupper-linux-two-site --local-site <name> --remote-site <name>
        --remote-host <ssh-host> --namespace <ns>
    
  3. Apply defaults for optional parameters — do not prompt for optional parameters unless the user explicitly mentions them.

  4. Confirm bindings before executing — show the resolved parameter table and ask for confirmation:

    Resolved parameters:
      LOCAL_SITE_NAME:  my-local
      REMOTE_SITE_NAME: my-remote
      REMOTE_SSH_HOST:  my-remote-host
      NAMESPACE:        playground
      TEST_PORT:        9090 (default)
    Proceed? [y/n]

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
