level85: Skill for Claude Code

.agents/skills/x-queue-kafka/SKILL.md

x-queue-kafka is a skill for Claude Code, Codex from pure-golang/level85. It costs 64 tokens per session (929 once invoked), scanned A, original, no licence file.

A guide for building Kafka publishers and subscribers through the project's queue adapter. Kafka is a system for sending and receiving messages between applications.

In plain words
What is it for?
Use it when implementing Kafka publishers or subscribers, selecting topics and consumer groups, configuring a balancer, or handling retry results.
Why use it?
It keeps message producers and consumers aligned with the project's existing adapter API and defaults. It also explains the available retry and consumer-group choices.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is pure-golang/level85's own configuration. It tells Claude Code and Codex how to work on level85 itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything level85 configures →

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

x-queue-kafka 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 6d 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.
