What it does

Tailscale is an agent skill from iii-hq/workers. Operate this host's Tailscale node from iii: connectivity and peers, routes and exit nodes, preferences, Taildrop file transfer, HTTPS certificates, publishing local services or the Console to the tailnet (Serve) or the internet (Funnel), accounts, tailnet lock, updates. Use it for anything a person would otherwise do with the tailscale CLI or the Tailscale app.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The licence is Apache-2.0.

When your agent uses it

  • Anything a person would otherwise do with the tailscale CLI
  • The Tailscale app

Example prompts

  • “/tailscale”

What it can do on your machine

Read from SKILL.md and the folder at commit 72ae6ab. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tailscale loads about 1.5k tokens when it runs. Until then it costs about 94 tokens; SKILL.md has 729 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~94
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Operate this host's Tailscale node from iii: connectivity and peers, routes and exit nodes, preferences, Taildrop file transfer, HTTPS certificates, publishing local services or the Console to the tailnet (Serve) or the internet (Funnel), accounts, tailnet lock, updates. Use it for anything a person would otherwise do with the `tailscale` CLI or the Tailscale app.

tailscale

The tailscale worker drives the installed tailscale CLI on the Console host and exposes its whole surface as typed functions, plus a Console page. Every function returns structured data with keys, secrets, and capability maps stripped; every command that changes network reachability or node behaviour is approval-gated. Requires Tailscale installed on the host; most functions also need the node signed in and connected.

Publishing has two visibilities. Serve is tailnet-only: reachable by devices signed into this tailnet, with Tailscale identity headers on every request. Funnel is public: reachable by anyone with the link, no identity headers, ports 443/8443/10000 only, and it needs allow_funnel in the worker configuration plus confirm_public on the request. Stopping a Funnel route removes public access and keeps the tailnet route; stopping a Serve route removes it entirely. The worker never runs serve reset or funnel reset unless serve::reset is called with confirm=true.

When to Use

  • A person asks whether Tailscale is connected, which devices are on the tailnet, what this node's Tailscale IP or MagicDNS name is, or why a peer is slow (DERP relay vs direct path).
  • A person wants a link or QR code to open the Console, or any local port, service, or directory, on another device.
  • A person wants to route traffic through an exit node, accept or advertise subnet routes, change hostname, shields-up, SSH, DNS, or auto-update.
  • A person wants to send a file to another device or collect files from the Taildrop inbox, get an HTTPS certificate for this node, switch accounts, check tailnet lock, or update the client.

Boundaries

  • Read functions (status, peers::list, netcheck, ping, whois, dns::*, prefs::get, serve::list, exit-node::list, …) are allowed by default. Everything else changes the node or the network and is approval-gated; do not chain approvals for a person, ask once per action.
  • Never publish anything publicly (mode: funnel) without the person's explicit yes in that conversation, and say that anyone with the link can open it.
  • Funnel needs a one-time tailnet-admin approval; share/serve::add return stage: authorization_required with the approval URL until that is done.
  • tailscale up refuses flags when non-default preferences exist, so connect runs it bare; change preferences with prefs::set, never by reconnecting.
  • Taildrive commands are rejected by the macOS GUI app (it manages Taildrive in its own settings); expect an error there.
  • serve::add targets must be a local port, a loopback URL, or an absolute path; file::send paths and cert output paths must be absolute.
  • The worker does not run tailscale ssh, nc, or web, and it does not edit the tailnet policy file.

Functions

Node and session:

  • tailscale::status — connectivity, node identity, health, Funnel allowed, peer counts, exit node in use, active routes.
  • tailscale::configuration — non-secret worker settings plus the raw Serve configuration.
  • tailscale::connect / tailscale::disconnect — tailscale up / tailscale down; connect returns a sign-in URL when the node needs a login.
  • tailscale::login / tailscale::logout — start a sign-in (returns the browser URL) or expire the node key.
  • tailscale::version — installed client version, optionally the latest upstream release.
  • tailscale::ip — Tailscale IPs of this node or of a peer.
  • tailscale::netcheck — UDP, IPv4/IPv6, NAT mapping, port mapping, preferred DERP and relay latencies.
  • tailscale::ping — ping a peer at the Tailscale layer; each reply says DERP or direct.
  • tailscale::whois — machine and user behind a Tailscale IP.
  • tailscale::dns::status / tailscale::dns::query — MagicDNS and split-DNS configuration; resolve a name through the forwarder.

Peers and preferences:

  • tailscale::peers::list — devices on the tailnet with IPs, OS, online state, tags, exit-node offers, relay, traffic counters.
  • tailscale::exit-node::list / tailscale::exit-node::suggest / tailscale::exit-node::set — exit nodes on offer, the best one, and switching or clearing the one in use.
  • tailscale::prefs::get / tailscale::prefs::set — read the node's preferences; change only the fields given (tailscale set).

Publishing:

  • tailscale::share / tailscale::share::stop — publish or stop the iii Console on a port and path.
  • tailscale::serve::list / tailscale::serve::add / tailscale::serve::remove — list every route; publish any local port, loopback URL, or directory; remove one route.
  • tailscale::serve::reset — remove every Serve and Funnel route on this node; needs confirm=true.

Files and certificates:

  • tailscale::file::targets / tailscale::file::send / tailscale::file::receive — Taildrop: who accepts files, send files to a device, move inbox files into a directory.
  • tailscale::cert — fetch a Let's Encrypt certificate and key for one of this node's MagicDNS domains.
  • tailscale::drive::list / tailscale::drive::share / tailscale::drive::unshare — Taildrive directory shares.

Administration:

  • tailscale::lock::status — tailnet lock state and this node's tailnet-lock key.
  • tailscale::accounts::list / tailscale::accounts::switch — accounts signed in on this device; switch the active one.
  • tailscale::update — update the client, or dry_run=true to see what would change.
  • tailscale::bugreport — a shareable diagnostic identifier for Tailscale support.
  • tailscale::metrics — client metrics in Prometheus text format.
