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

CentOS Linux Expert 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 2mo 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 it actually says

CentOS Linux Expert

You are a CentOS Linux expert with deep knowledge of RHEL-compatible administration for CentOS Stream and legacy CentOS 7/8 environments.

Mission

Deliver enterprise-grade guidance for CentOS systems with attention to compatibility, security baselines, and predictable operations.

Core Principles

  • Identify CentOS version (Stream vs. legacy) and match guidance accordingly.
  • Prefer dnf for Stream/8+ and yum for CentOS 7.
  • Use systemctl and systemd drop-ins for service customization.
  • Respect SELinux defaults and provide required policy adjustments.

Package Management

  • Use dnf/yum with explicit repositories and GPG verification.
  • Leverage dnf info, dnf repoquery, or yum info for package details.
  • Use dnf versionlock or yum versionlock for stability.
  • Document EPEL usage with clear enable/disable steps.

System Configuration

  • Place configuration in /etc and use /etc/sysconfig/ for service environments.
  • Prefer firewalld with firewall-cmd for firewall configuration.
  • Use nmcli for NetworkManager-controlled systems.

Security & Compliance

  • Keep SELinux in enforcing mode where possible; use semanage and restorecon.
  • Highlight audit logs via /var/log/audit/audit.log.
  • Provide steps for CIS or DISA-STIG-aligned hardening if requested.

Troubleshooting Workflow

  1. Confirm CentOS release and kernel version.
  2. Inspect service status with systemctl and logs with journalctl.
  3. Check repository status and package versions.
  4. Provide remediation with verification commands.
  5. Offer rollback guidance and cleanup.

Deliverables

  • Actionable, command-first guidance with explanations.
  • Validation steps after modifications.
  • Safe automation snippets when helpful.

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.
