CF tox-tunnel-ops
Encrypted P2P TCP tunneling for remote network access — a self-hosted VPN / ngrok / Tailscale alternative built on the Tox protocol (libsodium). No API keys, no accounts, no central servers, no port-forwarding. Solves NAT traversal, carrier-grade NAT, double NAT, intranet penetration (内网穿透), and remote machine access without router or firewall changes. Tunnels SSH, RDP/VNC desktops, database connections (PostgreSQL/MySQL/Redis/MongoDB), homelab/NAS access (Synology, TrueNAS), local dev servers, and arbitrary TCP ports. Use when: setting up remote SSH/RDP/MySQL/PostgreSQL/Redis/MongoDB access from anywhere, exposing a local dev server or internal web app, sharing a homelab/Synology/TrueNAS service, granting time-scoped contractor access, generating ToxTunnel server/client/rules YAML configs, diagnosing toxtunnel connection failures, tightening rules.yaml access control, running a loopback SOCKS5 / HTTP CONNECT listener through a Tox tunnel, exporting toxtunnel operational metrics into Prometheus / Grafana, hot-reloading rules without restart (SIGHUP / `toxtunnel reload`), inspecting live tunnel state via `toxtunnel inspect`, or wiring multi-server failover for production redundancy.
As a process F 49/100 · Will not run — References files that are not bundled: examples/*.md, scripts/install.ps1
How to improve
- Shorten the description to 1024 characters.
- The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
- The text references files that are not there: add them or drop the references.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

- 0Tools and files. 2 referenced file(s) missing: examples/*.md, scripts/install.ps1
- 0Inputs and preconditions. Does not say what the process needs to start
- 10Execution cost. Instruction body is 17745 tokens: crowds the task out of the window

- 60Result and completion. Output format stated, no completion criterion
- 85Steps. 271 steps, 1 vague phrases
- 100Failures and branches. 14 branches, has a failure section
- 100Consistency. Name and required fields are in place
- 100Progress reporting. Reports progress
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- low 11 top-level sections: this looks like several domains in one skill
- low The response is described with custom markup (20 tags): a typed call is more reliable
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
