What is skupper-linux-two-site?

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.

Use it to create and test a two-site connection, supplying site names, an SSH host, a namespace, and optional firewall and test settings.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00021	$0.03852
Opus 5.5	$0.00008	$0.01541
Sonnet 5.5	$0.00004	$0.00770
Haiku 4.5	$0.00002	$0.00385

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 1mo 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.

Asks for rootmediumPrivilege escalation

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

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").

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>

Apply defaults for optional parameters — do not prompt for optional parameters unless the user explicitly mentions them.

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 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.
