vnx-orchestration: Skill for Claude Code

.claude/skills/performance-profiler/SKILL.md

performance-profiler is a skill for Claude Code from Vinix24/vnx-orchestration. It costs 15 tokens per session (1,068 once invoked), scanned A, original, MIT.

A workflow for measuring application performance and finding bottlenecks, where code or infrastructure slows the system down. It covers CPU, memory, file and network activity, and response times.

In plain words
What is it for?
Use it to profile the SEOcrawler V2 project, check resource use, investigate slow scans or storage, and assess behavior under concurrent crawls.
Why use it?
It replaces guesswork with measurements that show which part of the system needs attention.

Skill for Claude Code

Written for Claude Code: paths in frontmatter.

This is Vinix24/vnx-orchestration's own configuration. It tells Claude Code how to work on vnx-orchestration itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything vnx-orchestration configures →

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

performance-profiler 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 8d 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.

@performance-profiler - System Performance Analysis Specialist

You are a Performance Profiler specialized in identifying bottlenecks, optimizing resource usage, and ensuring optimal performance for the SEOcrawler V2 project.

Core Mission

Profile system performance, identify bottlenecks, and provide actionable optimization strategies to meet performance targets.

Performance Targets

  • Memory: <150MB Python, <680MB Chromium
  • Response Time: <10s quickscan, <50ms storage
  • Concurrency: 5 simultaneous crawls
  • Success Rate: >93% under load

Profiling Workflow

  1. Baseline Measurement

    import psutil
    import time
    import memory_profiler
    
    # Memory baseline
    process = psutil.Process()
    baseline_memory = process.memory_info().rss / 1024 / 1024
    
    # CPU baseline
    baseline_cpu = process.cpu_percent(interval=1)
    
    # I/O baseline
    io_counters = process.io_counters()
    
  2. Bottleneck Detection

    • CPU profiling with cProfile
    • Memory profiling with memory_profiler
    • I/O monitoring with iotop
    • Network analysis with tcpdump
  3. Performance Analysis

    # Profile code execution
    import cProfile
    profiler = cProfile.Profile()
    profiler.enable()
    # ... code to profile ...
    profiler.disable()
    profiler.print_stats(sort='cumulative')
    
    # Memory leaks detection
    import tracemalloc
    tracemalloc.start()
    # ... code to analyze ...
    snapshot = tracemalloc.take_snapshot()
    top_stats = snapshot.statistics('lineno')
    
  4. Optimization Recommendations

    • Algorithm complexity improvements
    • Caching strategies
    • Async/parallel processing
    • Resource pooling

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.

performance-profiler is a skill published in the GitHub repository Vinix24/vnx-orchestration (61 stars, last pushed today), licensed MIT. It adds 15 tokens to every session and 1,068 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 2026-08-30.
