GL.iNet — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the gl-inet-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install gl-inet --cli-only
   

2. Verify: gl-inet-pp-cli --version
3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails before this CLI has a public-library category, install Node or use the category-specific Go fallback after publish.

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

Save a known-good 'home' config, adjust it at a hotel or abroad, then revert in one command with snapshot save/apply/diff. Get online at a new venue and fix the 'my foreign network is invisible' regulatory-domain problem instantly. Every command probes your exact model and firmware first, so it adapts instead of assuming — and it all runs locally over the router's own API, no GoodCloud.

When to Use This CLI

Use gl-inet for managing a GL.iNet travel router from the terminal or an agent: capturing and reverting config profiles while traveling, getting online at new venues, fixing regulatory-domain repeater problems, diagnosing 'no internet' and weak-uplink situations, and version/model-aware inspection of what a given firmware supports. It is local-only (the router's own API + SSH), with no GoodCloud dependency.

When Not to Use This CLI

Do not activate this CLI for requests that require creating, updating, deleting, publishing, commenting, upvoting, inviting, ordering, sending messages, booking, purchasing, or changing remote state. This printed CLI exposes read-only commands for inspection, export, sync, and analysis.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Travel config profiles

• snapshot save — Capture your whole router config as a named, reusable profile.

  Reach for this when the user wants to bank a known-good config before changing anything on the road.

  gl-inet-pp-cli snapshot save home --agent
  

• snapshot apply — Restore a saved profile, with a safety check that it matches this device.

  Use to revert cleanly to a standard config without risking a mismatched-device restore.

  gl-inet-pp-cli snapshot apply home --agent
  

• snapshot diff — See exactly which settings a venue changed vs your standard config.

  Use to answer 'what did this hotel network change?' before reverting.

  gl-inet-pp-cli snapshot diff home --agent
  

Travel macros

• wifi region diagnose — Find out why a foreign network is invisible and fix the regulatory domain in one command.

  Use when repeater mode can't see a network abroad (e.g. EU 2.4GHz ch12/13 under a US regdomain).

  gl-inet-pp-cli wifi region diagnose --agent
  

• venue connect — One command to get online at a new venue: scan, region-check, join, and prep for captive portals.

  Use on arrival at a hotel/cafe to skip the multi-step LuCI dance.

  gl-inet-pp-cli venue connect "Hotel WiFi" --agent
  

• vpn toggle — Start a VPN tunnel, arm the kill-switch, and confirm your public IP actually changed.

  Use to trust that the VPN is really protecting traffic, not just 'connected'.

  gl-inet-pp-cli vpn toggle mullvad --agent
  

• vpn verify — Verify the VPN is up and your connection isn't leaking: egress country, DNS leaks, and STUN/UDP (WebRTC-style) leaks.

  Use to confirm a VPN is actually protecting all traffic (no IP/DNS/WebRTC leak) before trusting it on an untrusted network.

  gl-inet-pp-cli vpn verify --expect-country US --agent
  

• wan mode — Switch the router's WAN source and verify it reconnected.

  Use when changing how the router gets upstream internet at a new venue.

  gl-inet-pp-cli wan mode repeater --agent
  

Diagnostics

• troubleshoot — Diagnose why the router has no internet and get the exact fix command.

  Use first whenever the router is up but there's no internet — most often it's not connected in repeater mode.

  gl-inet-pp-cli troubleshoot --agent
  

• uplink — Diagnose a weak/slow venue WiFi uplink and get ranked ways to improve it.

  Use when you have internet but it's bad and you want to know whether to move, switch bands, or tether.

  gl-inet-pp-cli uplink --agent
  

• doctor — Report this router's model, firmware, OpenWrt/LuCI versions, reachable surfaces, and per-feature availability.

  Use to confirm what a given firmware supports before relying on a feature.

  gl-inet-pp-cli doctor --agent
  

Power-user + config

• config summary — A structured, per-subsystem report of the router's current configuration.

  Use to quickly understand or capture the current state of a router.

  gl-inet-pp-cli config summary --agent
  

• config find — Find any config option anywhere across the whole router config tree.

  Use to locate where a setting lives when config is spread across dozens of modules.

  gl-inet-pp-cli config find country --agent
  

• rpc call — Call any GL RPC module/function or any UCI option directly.

  Use as the power-user fallback for anything not covered by a typed command.

  gl-inet-pp-cli rpc call netmode get_mode --agent
  

Command Reference

clients — Connected client devices

• gl-inet-pp-cli clients — List connected clients (ip, mac, name, tx/rx, online)

snapshots — Named config profiles captured from the router

• gl-inet-pp-cli snapshots — Saved config snapshots (local store)

system — Router system info and live status

• gl-inet-pp-cli system get — Model, firmware, OpenWrt version, hardware/software capability maps

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

gl-inet-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Recipes

Bank home, travel, revert

gl-inet-pp-cli snapshot save home && gl-inet-pp-cli snapshot diff home && gl-inet-pp-cli snapshot apply home

Capture a known-good profile, see what a venue changed, then revert cleanly.

Get online abroad

gl-inet-pp-cli venue connect "Hotel WiFi"

Scan, region-check, join, and prep for the captive portal in one command.

Fix an invisible foreign network

gl-inet-pp-cli wifi region diagnose --fix

Detects a network hidden by your regulatory domain and switches the region to unhide it.

Why is there no internet?

gl-inet-pp-cli troubleshoot --fix

Walks the connectivity decision tree and applies safe remedies (most often: not joined in repeater mode).

Narrow a verbose status payload for an agent

gl-inet-pp-cli system status --agent --select clients.online,wan.proto,wan.ip,memory.free

Use --select with dotted paths to return only the fields an agent needs from a large status response.

Auth Setup

Authenticates against the router's local admin password via GL's challenge/crypt/sha256 handshake (read from the live challenge, so it works across firmware versions). Config snapshots and UCI access use SSH to the router. No cloud account needed.

Run gl-inet-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

• Pipeable — JSON on stdout, errors on stderr

• Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

  gl-inet-pp-cli clients --agent --select id,name,status
  

• Previewable — --dry-run shows the request without sending

• Offline-friendly — sync/search commands can use the local SQLite store when available

• Non-interactive — never prompts, every input is a flag

• Read-only — do not use this CLI for create, update, delete, publish, comment, upvote, invite, order, send, or other mutating requests

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal AND no machine-format flag (--json, --csv, --compact, --quiet, --plain, --select) is set — piped/agent consumers and explicit-format runs get pure JSON on stdout.

Paths and state

Agents should treat the CLI's path resolver as part of the runtime contract:

• Use --home <dir> for one invocation, or set GL_INET_HOME=<dir> to relocate all four path kinds under one root.

• Use per-kind env vars only when a specific kind must diverge: GL_INET_CONFIG_DIR, GL_INET_DATA_DIR, GL_INET_STATE_DIR, GL_INET_CACHE_DIR.

• Resolution order is per-kind env var, --home, GL_INET_HOME, XDG (XDG_CONFIG_HOME, XDG_DATA_HOME, XDG_STATE_HOME, XDG_CACHE_HOME), then platform defaults.

• config contains settings like config.toml and profiles. data contains credentials.toml, data.db, cookies, and auth sidecars. state contains persisted queries, jobs, and teach.log. cache contains regenerable HTTP/cache files.

• Stored secrets live in credentials.toml under the data dir. Existing legacy config.toml secrets are read for compatibility and leave config.toml on the first auth write.

• Run gl-inet-pp-cli doctor --fail-on warn to surface path and credential-location warnings. agent-context exposes a schema v4 paths block for agents that need the resolved dirs.

• For MCP, pass relocation through the MCP host config. The MCP binary does not inherit CLI flags:

  {
    "mcpServers": {
      "gl-inet": {
        "command": "gl-inet-pp-mcp",
        "env": {
          "GL_INET_HOME": "/srv/gl-inet"
        }
      }
    }
  }
  

Fleet precedence: an inherited per-kind env var overrides an explicit --home for that kind. Use GL_INET_HOME or per-kind vars as durable fleet levers, and use --home only for a single invocation. Relocation is not reversible by unsetting env vars; move files manually before clearing GL_INET_HOME, or doctor will not find credentials left under the former root.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

gl-inet-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
gl-inet-pp-cli feedback --stdin < notes.txt
gl-inet-pp-cli feedback list --json --limit 10

Entries are stored locally as feedback.jsonl under the resolved data dir. They are never POSTed unless GL_INET_FEEDBACK_ENDPOINT is set AND either --send is passed or GL_INET_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

gl-inet-pp-cli profile save briefing --json
gl-inet-pp-cli --profile briefing clients
gl-inet-pp-cli profile list --json
gl-inet-pp-cli profile show briefing
gl-inet-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.

Exit Codes

Argument Parsing

Parse $ARGUMENTS:

1. Empty, help, or --help → show gl-inet-pp-cli --help output
2. Starts with install → ends with mcp → MCP installation; otherwise → see Prerequisites above
3. Anything else → Direct Use (execute as CLI command with --agent)

MCP Server Installation

Install the MCP binary from this CLI's published public-library entry or pre-built release, then register it:

claude mcp add gl-inet-pp-mcp -- gl-inet-pp-mcp

Verify: claude mcp list

Direct Use

1. Check if installed: which gl-inet-pp-cli If not found, offer to install (see Prerequisites at the top of this skill).
2. Match the user query to the best command from the Unique Capabilities and Command Reference above.
3. Execute with the --agent flag:

   gl-inet-pp-cli <command> [subcommand] [args] --agent
   

4. If ambiguous, drill into subcommand help: gl-inet-pp-cli <command> --help.
