tik4net: Skill for Claude Code

.claude/skills/mikrotik-cli-probe/SKILL.md

mikrotik-cli-probe is a skill for Claude Code from danikf/tik4net. It costs 166 tokens per session (2,055 once invoked), scanned A, original, Apache-2.0.

A diagnostic tool for checking the raw command-line output returned by a MikroTik router over Telnet or other terminal-style connections. MikroTik is a maker of routers, and RouterOS is their router operating system.

In plain words
What is it for?
Use it to debug tik4net Telnet, SSH terminal, MAC-Telnet, or WinBox command-line connections and inspect the bytes, prompts, and formatting the router actually sends.
Why use it?
It helps explain empty, garbled, or difficult-to-parse terminal output before troubleshooting the library that connects to the router. It can distinguish router behaviour from client or transport problems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mikrotik-cli-probe scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

MikroTik CLI probe (Telnet / PTY)

The binary API (mikrotik skill / mikrotik_call) is the right tool for normal queries. Use THIS skill when the question is specifically about the terminal/CLI layer: what RouterOS emits over a PTY, why a CLI command returns nothing, how to shape a command so its output is parseable, etc. This is the layer tik4net's CLI-based transports (tik4net/Cli/, tik4net/Telnet/) sit on.

Two ways to get terminal ground truth. The probe script below is the router-only view (no tik4net at all). To see the same raw bytes as tik4net itself sees them — through the actual transport, with the mepty pull cadence, VT100 answers and prompt/settle decisions the library makes — use mikrotik_call with traceLevel:'bytes' (channels telnet.sock, wbxcli.mepty, mactelnet.udp) and optionally includeRouterLog:true for the device-side log. That is the in-library equivalent of this probe and the faster first stop when the question is "what did our client do", not "what can the router do at all". See the mikrotik skill's Wire tracing & router-log debugging section. Reach for the standalone probe script when you need a reference implementation independent of tik4net.

Check which server answered. The MCP route runs a staged copy of the build output, so a trace can silently come from the server you had before your last build. Every answer names the assembly that produced it — mikrotik_call on a trailing --- MCP SERVER --- … built <timestamp> … line, mikrotik_cli_complete in its serverBuild property. If that timestamp predates your build, the trace is evidence about the OLD code; reconnect tik4net-mcp and take it again. The probe script has no such trap: it does not use the library at all, which is exactly why it stays the tie-breaker.

The probe script

Tools/probes/telnet-cli-probe.ps1 is a minimal, self-contained Telnet client that reproduces exactly what a correct PTY transport must do — Telnet IAC negotiation, VT100 cursor-probe answers, and login with change-password-nag dismissal — then prints the RAW bytes the router returns (ESC shown as \e, CR/LF as \r/\n). It deliberately does NOT use the tik4net library, so it gives you ground truth to compare the library against.

mikrotik-cli-probe is a skill published in the GitHub repository danikf/tik4net (198 stars, last pushed yesterday), licensed Apache-2.0. It adds 166 tokens to every session and 2,055 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
