hardware-performance-expert

hardware-performance-expert is a skill for Claude Code, Codex from yamaru-eu/hardware-probe. It costs 21 tokens per session (741 once invoked), scanned A, original, Apache-2.0.

A specialist workflow for examining computer hardware, diagnosing real-time performance problems, and assessing local machines for AI model use.

In plain words
What is it for?
Use it to inventory hardware, investigate high CPU or memory use, check swap and thermal throttling, improve AI inference speed, or evaluate upgrade options.
Why use it?
It helps identify whether slowness comes from processor, memory, graphics, temperature, power, or other system limits.

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

hardware-performance-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 7d 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.

Skill: Hardware & Performance Expert

This skill is your primary expert for everything related to your machine's physical capabilities and real-time health. It provides deep diagnostics and actionable solutions for performance bottlenecks.

When to use

Activate this skill whenever you need to:

  1. Inventory: Get a detailed report of the local hardware (CPU, RAM, GPU, OS).
  2. Troubleshoot: Resolve slowness, high resource usage, or thermal throttling.
  3. AI Optimization: Evaluate LLM compatibility and optimize inference speeds.
  4. Upgrades: Get technical recommendations for hardware improvements.

Performance Troubleshooting Protocol

1. Resource Saturation Analysis

  • Tool: analyze_performance, analyze_ram_pressure
  • CPU Threshold: If currentLoad > 80% sustained, identify top processes and recommend actions.
  • RAM Threshold: If memory_used_percent > 90%, run analyze_ram_pressure to analyze swap usage and top RSS processes.

2. Thermal & Power Bottlenecks

  • Context: High-end hardware performing below expectations.
  • Action: Call thermal_profile to check for temperature spikes or frequency clipping (throttling) and suggest environmental fixes.

3. Storage Performance

  • Tool: analyze_local_system, check_storage_health
  • Action: Monitor SSD fill rates (> 90%). Call check_storage_health to verify SMART status and identify legacy HDDs slowing down modern workflows.

4. Dev Environment & Security

  • Context: Slow build times or "permission denied" errors on dev paths.
  • Action: Call diagnose_antivirus_impact to detect EDR/Antivirus exclusion coverage on project hot paths.

5. Time-Bound Monitoring

  • Context: Transient issues that happen during a specific task (e.g., "The machine slows down only when I compile" or "Inference starts fast then lags").
  • Action: Call monitor_system_health with a duration (e.g., 30s) to collect statistical data (min/max/avg) while the problematic task is running.

hardware-performance-expert is a skill published in the GitHub repository yamaru-eu/hardware-probe (7 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 21 tokens to every session and 741 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
