kafka-backup CLAUDE.md

kafka-backup CLAUDE.md is an instructions file for coding agents from osodevops/kafka-backup. It costs 3,581 tokens per session, scanned A, original, MIT.

A CLAUDE.md development guide for OSO Kafka Backup & Restore, a Rust tool that saves and restores Apache Kafka data.

In plain words
What is it for?
Use it when developing the Kafka backup project, especially work involving cloud or local backups, point-in-time recovery, or consumer-group offsets.
Why use it?
It gives an AI coding assistant project context, including the problems the repository solves, its layout, and how to build and test it.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

kafka-backup CLAUDE.md 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 3d 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.

CLAUDE.md - Development Guide for OSO Kafka Backup & Restore

This document provides context for AI-assisted development on this project.

Project Overview

OSO Kafka Backup & Restore is a high-performance, production-grade tool written in Rust for backing up and restoring Apache Kafka topics to cloud storage or local filesystem. It supports point-in-time recovery (PITR) with millisecond precision and handles consumer group offset recovery across different clusters.

Key Problems Solved

  • Durable backup of Kafka topics to S3, Azure Blob, GCS, or local filesystem
  • Disaster recovery with exact data fidelity
  • Point-in-time restore (PITR) with millisecond precision
  • Consumer group offset recovery across different clusters (offset space discontinuity problem)
  • Deployment-agnostic: works on bare metal, VM, Docker, Kubernetes

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.
