arch-knowledge-patch is a skill for Claude Code from Nevaberry/nevaberry-plugins. It costs 8 tokens per session (1,966 once invoked), scanned A, original, MIT.

A focused Arch Linux reference for package upgrades, service migrations, runtime changes, and security-related operations. Arch Linux is a Linux distribution whose system packages and services can require specific upgrade steps.

In plain words
What is it for?
Use it when upgrading Arch systems, reviewing configuration changes, migrating services, or restarting the SSH daemon after upgrading OpenSSH to 9.8p1.
Why use it?
It highlights upgrade interventions that can prevent outages or broken services, especially after changes such as an OpenSSH upgrade.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

arch-knowledge-patch 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 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.

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.

Reference index

Reference Topics
Package management pacman 7.0.0 and 7.1.0 sandboxing and signatures, makepkg and PKGBUILD changes, repositories, repo-add, firmware packaging, package-source licensing
Service migrations OpenSSH and rsync interventions, Redis to Valkey, Zabbix accounts, Dovecot 2.4, nft-backed iptables, Kea ownership, Vinyl Cache

Operations and security Arch service outage fallbacks, AUR package auditing

Use this patch

  1. Read the package-management reference before changing pacman.conf, maintaining PKGBUILDs, running private repositories, or automating pacman 7.0.0 or 7.1.0.
  2. Check the intervention tables before a full system upgrade, especially on remote hosts, servers, and graphical workstations.
  3. Read the relevant migration reference before accepting renamed packages, accounts, directories, units, or configuration formats.
  4. Review .pacnew and .pacsave files instead of assuming package upgrades preserve local configuration.
  5. Perform Arch upgrades as full upgrades; do not turn an intervention into a partial-upgrade workflow.

Breaking changes and required interventions

Restart OpenSSH after the 9.8p1 upgrade

Restart the daemon immediately after upgrading openssh to 9.8p1 because the old daemon cannot accept new connections:

systemctl try-restart sshd

On a remote host, preserve an existing session until the restarted daemon accepts a new connection.

Upgrade rsync everywhere

Upgrade every rsync daemon and client to Arch package 3.4.0-1 or newer, then reboot. Treat public mirrors as urgent: vulnerable anonymous servers can permit remote code execution, and hostile servers can attack connecting clients and sensitive files.

Changes

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.
