What it does

Performance Testing is an agent skill from foryourhealth111-pixel/Vibe-Skills. Benchmark indicator performance with BenchmarkDotNet. Use for Series/Buffer/Stream benchmarks, regression detection, and optimization patterns. Target 1.5x Series for StreamHub, 1.2x for BufferList.

What it can do on your machine

Read from SKILL.md and the folder at commit ddcaa2a. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- dotnet
- pwsh
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Performance Testing loads about 779 tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 55 tokens; SKILL.md has 181 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~55
When it runs · the whole SKILL.md, loaded when a task matches: ~779
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Performance testing

Running benchmarks

bash

cd tools/performance

# Run all benchmarks (~15-20 minutes)
dotnet run -c Release

# Run specific category
dotnet run -c Release --filter *StreamIndicators*
dotnet run -c Release --filter *BufferIndicators*
dotnet run -c Release --filter *SeriesIndicators*

# Run specific indicator
dotnet run -c Release --filter *.EmaHub

Adding benchmarks

Series pattern

csharp

[Benchmark]
public void ToMyIndicator() => quotes.ToMyIndicator(14);

Stream pattern

csharp

[Benchmark]
public object MyIndicatorHub() => quoteHub.ToMyIndicatorHub(14).Results;

Buffer pattern

csharp

[Benchmark]
public MyIndicatorList MyIndicatorList() => new(14) { quotes };

Style comparison

csharp

[Benchmark]
public IReadOnlyList<MyResult> MyIndicatorSeries() => quotes.ToMyIndicator(14);

[Benchmark]
public IReadOnlyList<MyResult> MyIndicatorBuffer() => quotes.ToMyIndicatorList(14);

[Benchmark]
public IReadOnlyList<MyResult> MyIndicatorStream() => quoteHub.ToMyIndicator(14).Results;

Performance targets

Note: These are optimization goals for future v3.1+ effort. Current implementations vary—see PERFORMANCE_ANALYSIS.md for actual measured performance. Some indicator families (e.g., EMA) have inherent framework overhead due to simple operation costs.

Style	Target vs Series	Use Case
Series	Baseline	Batch processing
BufferList	≤ 1.2x	Incremental data
StreamHub	≤ 1.5x	Real-time feeds

Expected execution times (502 periods)

Note: These are optimization targets. Actual execution times vary by indicator complexity and current implementation.

Complexity	Time	Examples
Fast	< 30μs	SMA, EMA, WMA, RSI
Medium	30-60μs	MACD, Bollinger Bands, ATR
Complex	60-100μs	HMA, ADX, Stochastic
Advanced	100-200μs+	Ichimoku, Hurst

Regression detection

bash

# Auto-detect baseline and results
pwsh detect-regressions.ps1

# Custom threshold (default 10%)
pwsh detect-regressions.ps1 -ThresholdPercent 15

Exit codes:

0 - No regressions
1 - Regressions found

Creating baselines

bash

cp BenchmarkDotNet.Artifacts/results/Performance.*-report-full.json \
   baselines/baseline-v3.0.0.json

Required optimization patterns

Minimize allocations in hot paths
Avoid LINQ in performance-critical loops
Use Span<T> for zero-copy operations
Cache calculations when possible
Test with realistic data sizes (502 periods)

Prohibited patterns

Excessive LINQ in hot paths
Boxing/unboxing of value types
Unnecessary string allocations
Redundant calculations in loops
Poor cache locality

See references/benchmark-patterns.md for detailed patterns.

When should I use Performance Testing?

Performance Testing fits situations like: series/Buffer/Stream benchmarks; regression detection; optimization patterns.

How do I install Performance Testing in Claude Code?

Run `npx skills add foryourhealth111-pixel/Vibe-Skills --skill performance-testing -a claude-code`. Or copy the skill folder (bundled/skills/performance-testing in foryourhealth111-pixel/Vibe-Skills) into .claude/skills/performance-testing in your project. Claude Code loads it when a task matches its description.

How do I install Performance Testing in Codex?

Run `npx skills add foryourhealth111-pixel/Vibe-Skills --skill performance-testing -a codex`. Or copy the skill folder (bundled/skills/performance-testing in foryourhealth111-pixel/Vibe-Skills) into .agents/skills/performance-testing in your project. Codex loads it when a task matches its description.

Can I use Performance Testing in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add foryourhealth111-pixel/Vibe-Skills --skill performance-testing -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/performance-testing, .gemini/skills/performance-testing, .github/skills/performance-testing and .opencode/skills/performance-testing in your project.

What does Performance Testing need to run?

Going by SKILL.md and its folder, Performance Testing needs the command-line tools its instructions call (dotnet and pwsh).

Does Performance Testing access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Performance Testing safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Performance Testing use?

Performance Testing is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Performance Testing use?

About 779 tokens (SKILL.md is roughly 3.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 934 tokens, read only when the agent opens those files.

What are the alternatives to Performance Testing?

Skills that share tags, products or a category with Performance Testing: Writing Livekit Scenarios (livekit-examples/agent-starter-python, 264 stars), Go Testing (cxuu/golang-skills, 172 stars), Goalcraft (grp06/goalcraft, 102 stars) and Thinking Partner (mattnowdev/thinking-partner, 206 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Performance Testing?

foryourhealth111-pixel (a GitHub user) maintains it in foryourhealth111-pixel/Vibe-Skills, which has 3,612 GitHub stars. The repository holds 81 skills in this directory. The repository was last updated on August 31, 2026.
