fldigi-operating

fldigi-operating is a skill for Claude Code, Codex from sbrunner-atx/fldigi-mcp. It costs 100 tokens per session (1,160 once invoked), scanned A, original, GPL-3.0.

An operating guide for using fldigi, a digital radio application, during live two-way radio contacts. It explains how to switch from transmitting back to receiving and how to check incoming messages.

In plain words
What is it for?
It is for sending radio messages, ending each transmission with an immediate return to receive, formatting line breaks correctly, and polling the receive buffer between transmissions.
Why use it?
It prevents the transmitter from staying keyed after a message ends, which could send unwanted carrier and hide the other station’s reply.

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

fldigi-operating 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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
