README

README is a command for Claude Code from openshift-eng/two-node-toolbox. It costs 0 tokens per session (3,067 once invoked), scanned B, original, Apache-2.0.

A set of troubleshooting instructions for etcd and Pacemaker in two-node OpenShift clusters with fencing. It includes diagnostic collection, analysis guidance, repair procedures, and verification advice.

In plain words
What is it for?
Use it to validate cluster access, collect diagnostics from virtual machines and OpenShift, investigate etcd or Pacemaker problems, apply documented remedies, and check preventive measures.
Why use it?
It gives an agent a structured way to investigate cluster failures and work toward their root causes instead of relying on ad-hoc checks.

Command for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; mentions Claude Code.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is ├── ../../../helpers/etcd/ # Helper scripts and playbooks.

Good fit Use it to validate cluster access, collect diagnostics from virtual machines and OpenShift, investigate etcd or Pacemaker problems, apply documented remedies, and check preventive measures.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 B, and why

README scanned grade B with 1 finding 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 1mo 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.

A mod that escalates privileges can change anything on the machine, not only the project.

Etcd Troubleshooting Skill for Two-Node Clusters

This directory contains the etcd/Pacemaker troubleshooting skill for Claude Code, designed specifically for two-node OpenShift clusters with fencing topology.

Overview

The etcd troubleshooting skill enables Claude to interactively diagnose and resolve etcd and Pacemaker issues on two-node clusters. It provides:

  • Automated diagnostic data collection from cluster VMs and OpenShift
  • Systematic analysis frameworks for identifying root causes
  • Step-by-step remediation procedures
  • Verification and prevention recommendations

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.

README is a command published in the GitHub repository openshift-eng/two-node-toolbox (5 stars, last pushed 3d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 3,067 tokens. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
