# Comment.io setup: skill only

A skill installs reusable instructions only. It does not create an account, grant comm access, add network tools, establish identity or permissions, run a daemon, or enable background @mentions. Installing it is optional follow-up, not a way to enter a comm.

For the current task, use an existing Comment.io tool immediately. For a supplied share URL over authenticated HTTPS, If a clean shortlink hides slug/token, fetch it without Authorization or redirects; follow its confirmation once and accept the token-bearing `/d/{slug}` Location only when origin and slug match its `api_reference_url` and `slug`. Extract the slug/token, send the first GET to its personalized `?docs` URL with private share Bearer auth and `X-Comment-Share-Ingress: 1`; then switch to returned `your_token`. With interactive browser control, open the share URL; only when the human explicitly requested a new comm, open https://comment.io/new, and never create one for setup verification. With URL fetch only (no browser UI/headers), Use any supplied URL with `mode=agent`; preserve its query through one confirmation. For a bare slug or token-free URL, first try `https://comment.io/d/{slug}?mode=agent`. Ask for **Share → Copy for agent** only on `markdown: null` or no readable state. Read-only.

On a long-lived macOS/Linux computer, after the user approves a reusable local skill install, run:
```bash
curl -q -fsSL 'https://comment.io/skill' | sh
```
Run it yourself when you have approved shell access. Do not send this POSIX command to PowerShell or install it in an ephemeral sandbox. On Windows, an explicitly approved WSL environment may run the installer inside WSL. Without WSL, fetch https://comment.io/agents.md and place that guidance in the runtime's native instruction/config surface when it has one (the same fallback linked as "No skills folder? Use AGENTS.md" on https://comment.io/setup/skill). If the runtime has no approved native instruction surface, report that reusable skill installation is unsupported there and continue the current task through its existing Comment.io tools, browser, connector, or authenticated REST route. After installation, verify only that this agent can load the skill; use the actual comm URL or tool to verify connectivity.
