+# nordvpn-client
+
+Cross-platform NordVPN lifecycle skill for macOS and Linux.
+
+## What it does
+
+- Probes whether NordVPN is already installed
+- Bootstraps NordVPN if missing
+- Handles login bootstrap
+- Connects to a country or city target
+- Disconnects and reports status
+- Verifies public IP and geolocation after connect
+
+## Commands
+
+```bash
+node skills/nordvpn-client/scripts/nordvpn-client.js status
+node skills/nordvpn-client/scripts/nordvpn-client.js install
+node skills/nordvpn-client/scripts/nordvpn-client.js login
+node skills/nordvpn-client/scripts/nordvpn-client.js verify
+node skills/nordvpn-client/scripts/nordvpn-client.js verify --country "Italy"
+node skills/nordvpn-client/scripts/nordvpn-client.js verify --country "Italy" --city "Milan"
+node skills/nordvpn-client/scripts/nordvpn-client.js connect --country "Italy"
+node skills/nordvpn-client/scripts/nordvpn-client.js connect --city "Milan"
+node skills/nordvpn-client/scripts/nordvpn-client.js disconnect
+```
+
+## Platform behavior
+
+### macOS
+
+- install path: `brew install --cask nordvpn`
+- probe order:
+  - `nordvpn` CLI if present
+  - `NordVPN.app`
+- if the installed package exposes a usable CLI, the skill uses it
+- otherwise it opens the app and returns a clear manual-action-required result for login/connect/disconnect
+
+### Linux
+
+- install path follows NordVPN's official installer script
+- primary control path is the official `nordvpn` CLI
+- token login is supported through `nordvpn login --token <token>`
+
+## Credentials
+
+Supported env vars:
+
+- `NORDVPN_TOKEN`
+- `NORDVPN_TOKEN_FILE`
+- `NORDVPN_USERNAME`
+- `NORDVPN_PASSWORD`
+- `NORDVPN_PASSWORD_FILE`
+
+Do not put secrets in the skill docs or repo.
+
+## Verification model
+
+`status`, `verify`, and `connect` emit JSON suitable for agent use:
+
+- platform
+- install state
+- auth state
+- connection state
+- requested target
+- public IP / geolocation lookup
+
+After `connect`, the intended workflow is:
+
+1. `nordvpn-client connect ...`
+2. `nordvpn-client verify ...` if an explicit location check is needed
+3. run the follow-up task such as `web-automation`
+
+## Limitations
+
+- Linux city targeting is attempted through the CLI target string and then validated by public IP/location checks.
+- macOS app-only fallback cannot guarantee non-interactive control if the app does not expose a CLI.

+# NordVPN Client Skill Design
+
+## Goal
+Create a `nordvpn-client` skill that works on macOS and Linux gateway hosts. It should detect whether NordVPN is already installed, bootstrap it if missing, handle login/auth setup, connect to a requested country or city, verify the VPN state and public IP location, disconnect when requested, and then be usable alongside other skills like `web-automation`.
+
+## Architecture
+The skill exposes one logical interface with platform-specific backends. Linux uses the official NordVPN CLI path. macOS probes for a usable CLI first, but falls back to the official app workflow when needed. The skill is responsible only for VPN lifecycle and verification, not for wrapping arbitrary commands inside a VPN session.
+
+## Interface
+Single script entrypoint:
+- `node scripts/nordvpn-client.js install`
+- `node scripts/nordvpn-client.js login`
+- `node scripts/nordvpn-client.js connect --country "Italy"`
+- `node scripts/nordvpn-client.js connect --city "Milan"`
+- `node scripts/nordvpn-client.js disconnect`
+- `node scripts/nordvpn-client.js status`
+
+## Platform Model
+### Linux
+- Probe for `nordvpn`
+- If missing, bootstrap official NordVPN package/CLI
+- Prefer token-based login for non-interactive auth
+- Connect/disconnect/status through official CLI
+
+### macOS
+- Probe for `nordvpn` CLI if available
+- Otherwise probe/install the official app
+- Use CLI when present, otherwise automate the app/login flow
+- Verify connection using app/CLI state plus external IP/geolocation
+
+## Auth and Safety
+- Do not store raw NordVPN secrets in skill docs
+- Read token/credentials from env vars or a local credential file path
+- Keep the skill focused on install/login/connect/disconnect/status
+- After `connect`, verify both local VPN state and external IP/location before the agent proceeds to tasks like `web-automation`
+
+## Verification
+- `status` reports platform, install state, auth state, connection state, and public IP/location check
+- `connect` verifies the requested target as closely as available data allows
+- Local validation happens first in the OpenClaw workspace, then the proven skill is copied into `stef-openclaw-skills`, documented, committed, and pushed

+# NordVPN Client Skill Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Build a cross-platform `nordvpn-client` skill for macOS and Linux that can install/bootstrap NordVPN, log in, connect to a target country or city, verify the VPN session, disconnect, and report status.
+
+**Architecture:** Implement one skill with one script entrypoint and platform-specific backends. Linux uses the official NordVPN CLI. macOS uses a CLI path when present and otherwise falls back to the NordVPN app workflow. The skill manages VPN state only, leaving follow-up operations like `web-automation` to separate agent steps.
+
+**Tech Stack:** Node.js, shell/OS commands, NordVPN CLI/app integration, OpenClaw skills, git
+
+---
+
+### Task 1: Create isolated worktree
+
+**Files:**
+- Modify: repo git metadata only
+
+**Step 1: Create worktree**
+
+Run:
+```bash
+git -C /Users/stefano/.openclaw/workspace/projects/stef-openclaw-skills worktree add /Users/stefano/.openclaw/workspace/projects/stef-openclaw-skills/.worktrees/nordvpn-client -b feature/nordvpn-client
+```
+
+**Step 2: Verify baseline**
+
+Run:
+```bash
+git -C /Users/stefano/.openclaw/workspace/projects/stef-openclaw-skills/.worktrees/nordvpn-client status --short --branch
+```
+Expected: clean feature branch
+
+### Task 2: Create the local skill runtime
+
+**Files:**
+- Create: `skills/nordvpn-client/SKILL.md`
+- Create: `skills/nordvpn-client/scripts/nordvpn-client.js`
+- Optional Create: helper files under `skills/nordvpn-client/scripts/`
+
+**Step 1: Write the failing checks**
+- Missing command/action should fail with clear usage output
+- Unsupported platform should fail clearly
+
+**Step 2: Implement platform detection and install probe**
+- detect `darwin` vs `linux`
+- detect whether NordVPN CLI/app is already present
+- expose `status` with install/auth/connect fields
+
+### Task 3: Implement install and auth bootstrap
+
+**Files:**
+- Modify: `skills/nordvpn-client/scripts/nordvpn-client.js`
+
+**Step 1: Linux install/login path**
+- implement official CLI probe/install path
+- implement token-based login path
+
+**Step 2: macOS install/login path**
+- probe CLI first
+- if absent, probe/install NordVPN app path
+- implement login/bootstrap state verification for the app workflow
+
+**Step 3: Keep secrets external**
+- env vars or local credential path only
+- no raw secrets in docs or skill text
+
+### Task 4: Implement connect/disconnect/status/verification
+
+**Files:**
+- Modify: `skills/nordvpn-client/scripts/nordvpn-client.js`
+
+**Step 1: Connect**
+- support `--country` and `--city`
+- normalize target handling per platform
+
+**Step 2: Verify**
+- report local connection state
+- run public IP / geolocation verification
+- fail if connection target cannot be reasonably verified
+
+**Step 3: Disconnect and status**
+- implement clean disconnect
+- ensure `status` emits machine-readable output for agent use
+
+### Task 5: Validate locally in OpenClaw workspace
+
+**Files:**
+- Test: local workspace copy of `nordvpn-client`
+
+**Step 1: Direct command validation**
+- usage errors are correct
+- install probe works on this host
+- status output is coherent before login/connect
+
+**Step 2: One real connect flow**
+- connect to a test country/city if credentials are available
+- verify local state + external IP/location
+- disconnect cleanly
+
+### Task 6: Promote to repo docs and publish
+
+**Files:**
+- Modify: `README.md`
+- Modify: `docs/README.md`
+- Create: `docs/nordvpn-client.md`
+- Create/Modify: `skills/nordvpn-client/...`
+
+**Step 1: Document the skill**
+- install/bootstrap behavior
+- auth expectations
+- connect/disconnect/status commands
+- macOS vs Linux notes
+
+**Step 2: Commit and push**
+
+Run:
+```bash
+git add skills/nordvpn-client docs README.md
+git commit -m "feat: add nordvpn client skill"
+git push -u origin feature/nordvpn-client
+```
+
+**Step 3: Merge and cleanup**
+- fast-forward or merge to `main`
+- push `main`
+- remove the worktree
+- delete the feature branch

+
+# NordVPN Client
+
+Cross-platform NordVPN lifecycle management for macOS and Linux hosts.
+
+## What This Skill Is For
+
+- Probing whether NordVPN is already installed
+- Bootstrapping NordVPN if it is missing
+- Logging in through the Linux CLI or the macOS app/CLI path
+- Connecting to a country or city before a follow-up action such as `web-automation`
+- Disconnecting and checking VPN status
+- Verifying public IP and geolocation after connect
+
+## Command Surface
+
+```bash
+node scripts/nordvpn-client.js status
+node scripts/nordvpn-client.js install
+node scripts/nordvpn-client.js login
+node scripts/nordvpn-client.js verify
+node scripts/nordvpn-client.js verify --country "Italy"
+node scripts/nordvpn-client.js verify --country "Italy" --city "Milan"
+node scripts/nordvpn-client.js connect --country "Italy"
+node scripts/nordvpn-client.js connect --city "Milan"
+node scripts/nordvpn-client.js connect --country "Italy" --city "Milan"
+node scripts/nordvpn-client.js disconnect
+```
+
+## Platform Notes
+
+- Linux:
+  - uses the official `nordvpn` CLI
+  - install path follows NordVPN's Linux installer
+  - token login is supported through `NORDVPN_TOKEN`
+- macOS:
+  - prefers Homebrew cask install: `brew install --cask nordvpn`
+  - prefers a usable `nordvpn` CLI if the installed package exposes one
+  - otherwise falls back to opening the NordVPN app and guiding the manual login/connect path
+
+## Credentials
+
+Do not store secrets in this skill.
+
+Supported env vars:
+
+- `NORDVPN_TOKEN`
+- `NORDVPN_USERNAME`
+- `NORDVPN_PASSWORD`
+
+Optional credential file env vars:
+
+- `NORDVPN_TOKEN_FILE`
+- `NORDVPN_PASSWORD_FILE`
+
+## Verification Behavior
+
+`status`, `verify`, and `connect` report machine-readable JSON including:
+
+- platform
+- install state
+- auth state
+- connection state
+- requested target
+- public IP lookup and geolocation
+
+Use this skill first, then run the follow-up task under the active VPN session.
+Use `verify` when you want an explicit post-connect location check without changing VPN state.
+
+## Known Boundaries
+
+- Linux country connect is official CLI behavior.
+- Linux city connect is attempted through the CLI target string and then validated by post-connect IP/location checks.
+- macOS app-only fallback cannot guarantee non-interactive login/connect if the installed app does not expose a CLI. In that case the skill will open the app and return a clear manual-action-required result.
