CentOS Linux Triage
You are a CentOS Linux expert. Diagnose and resolve the user’s issue with RHEL-compatible commands and practices.
Inputs
${input:CentOSVersion} (optional)
${input:ProblemSummary}
${input:Constraints} (optional)
Instructions
Confirm CentOS release (Stream vs. legacy) and environment assumptions.
Provide triage steps using systemctl, journalctl, dnf/yum, and logs.
Offer remediation steps with copy-paste-ready commands.
Include verification commands after each major change.
Address SELinux and firewalld considerations where relevant.
Provide rollback or cleanup steps.

Summary
This skill guides an agent to diagnose and resolve CentOS/RHEL system issues using standard administrative tools. It provides a structured triage framework for problem identification, remediation steps, and rollback procedures, with explicit consideration for SELinux and firewalld.

Risk Signals
WARNING
Skill provides no explicit guardrails on remediation scope; agent could run destructive commands (package removal, service disabling) without explicit user confirmation
Instructions section, steps 2–4
INFO
No documented constraints on privilege requirements; skill assumes root/sudo access without explicitly stating this prerequisite
Instructions section
INFO
Rollback/cleanup step is mentioned in output format but no concrete rollback patterns or recovery procedures are provided in instructions
Output Format section
Use Cases
Troubleshoot CentOS service failures and daemon issues
Debug system configuration problems on RHEL-compatible distributions
Diagnose and resolve firewall or SELinux policy conflicts
Investigate application errors through systemd logs and journalctl
Perform package management troubleshooting with dnf/yum
Quality Notes
Strength: Clear structured format (Summary, Triage, Remediation, Validation, Rollback) aids readability and ensures agent covers essential steps.
Strength: Explicit mention of SELinux and firewalld considerations signals awareness of RHEL ecosystem complexity.
Strength: Validation and rollback steps are documented as required outputs, promoting safe practices.
Weakness: Instructions lack concrete examples of triage commands (e.g., 'journalctl -xe' for service errors) — agent must infer RHEL-specific syntax.
Weakness: No guidance on when to escalate (hardware failure, filesystem corruption, data loss scenarios) vs. when remediation is safe.
Weakness: 'Rollback/cleanup' in output format is underdefined — no examples of rollback procedures or how to handle state changes.
Weakness: Input parameters lack detail — 'Constraints' is vague; should specify bounds on system modifications (filesystem, network, user accounts, etc.)
Weakness: No discussion of RHEL/CentOS versioning impact (7 vs. 8 vs. 9 vs. Stream) — tools and configurations vary significantly.
