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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.03600 |
| Opus 5.5 | $0.00020 | $0.01440 |
| Sonnet 5.5 | $0.00010 | $0.00720 |
| Haiku 4.5 | $0.00005 | $0.00360 |
Grade A, and why
administering-linux scanned grade A 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.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
usermod -aG sudo username # Add to sudo group Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Linux Administration
Comprehensive Linux system administration for managing servers, deploying applications, and troubleshooting production issues in modern cloud-native environments.
Purpose
This skill teaches fundamental and intermediate Linux administration for DevOps engineers, SREs, backend developers, and platform engineers. Focus on systemd-based distributions (Ubuntu, RHEL, Debian, Fedora) covering service management, process monitoring, filesystem operations, user administration, performance tuning, log analysis, and network configuration.
Modern infrastructure requires solid Linux fundamentals even with containerization. Container hosts run Linux, Kubernetes nodes need optimization, and troubleshooting production issues requires understanding systemd, processes, and logs.
Not Covered:
- Advanced networking (BGP, OSPF) - see
network-architectureskill - Deep security hardening (compliance, pentesting) - see
security-hardeningskill - Configuration management at scale (Ansible, Puppet) - see

When to Use This Skill
Use when deploying custom applications, troubleshooting slow systems, investigating service failures, optimizing workloads, managing users, configuring SSH, monitoring disk space, scheduling tasks, diagnosing network issues, or applying performance tuning.
Quick Start
Essential Commands
Service Management:
systemctl start nginx # Start service
systemctl stop nginx # Stop service
systemctl restart nginx # Restart service
systemctl status nginx # Check status
systemctl enable nginx # Enable at boot
journalctl -u nginx -f # Follow service logs
Process Monitoring:
top # Interactive process monitor
htop # Enhanced process monitor
ps aux | grep process_name # Find specific process
kill -15 PID # Graceful shutdown (SIGTERM)
kill -9 PID # Force kill (SIGKILL)

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.

administering-linux is a skill published in the GitHub repository ancoleman/ai-design-components (524 stars, last pushed 10mo ago), licensed MIT. It adds 49 tokens to every session and 3,600 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
