tunneling

**Judgment:** This skill is a practical, lightweight tunneling utility well-suited for development and demo workflows where an agent needs to expose a local service to the internet quickly. It leverages SSH (commonly available) and a third-party service (tinyfi.sh) to produce public HTTPS URLs for arbitrary local ports. **Key strengths:** - Very low friction: no signup, no extra binaries beyond SSH. - Supports custom subdomains and keep-alive settings for more stable, predictable tunnels. - Ideal for webhooks, quick demos, and sharing in-progress work without deployment. **Risks and limitations:** - **Security exposure:** Any tunneled local port becomes publicly reachable; if the local service has weak auth or sensitive data, this can lead to data leakage or unauthorized access. The agent or user must ensure only intended services are exposed and that they are properly secured. - **Third-party dependency:** Availability, latency, and rate limits (SSH and HTTP) are controlled by tinyfi.sh; tunnels may drop or be throttled under load or after idle timeouts. - **Environment assumptions:** Requires a functioning SSH client and the ability to maintain outbound SSH connections; restricted environments may block or kill long-lived tunnels. **Recommended scenarios:** - Development and testing environments where quick, temporary public access to localhost is needed (e.g., webhook debugging, live demos, remote QA). - Situations where security sensitivity is moderate and the team understands the implications of exposing local services. - Not recommended for long-term production exposure of critical or highly sensitive services; a more controlled, audited tunneling or hosting solution is preferable there.
