borrowed-wire-protocol-discipline

borrowed-wire-protocol-discipline is a skill for Claude Code from maxrave-dev/kotlin-footguns. It costs 94 tokens per session (1,565 once invoked), scanned A, original, GPL-3.0.

A rule set for implementing a communication protocol defined by another system. A protocol is the agreed format and behavior that software uses to exchange messages.

In plain words
What is it for?
It helps build clients that follow an existing protocol exactly, decode unknown message types safely, and restrict supported features to those actually agreed with the counterpart.
Why use it?
It prevents compatibility bugs caused by renaming fields, changing their order, guessing omitted constants, rejecting unknown messages, or claiming capabilities the other side did not negotiate.

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

borrowed-wire-protocol-discipline 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 10d 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.

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.
