Vibe-Skills is a collection and routing system that helps AI agents discover, select, and coordinate specialized skills for completing tasks. It is intended for agents that need to organize workflows across many installed capabilities. The catalogue entries are skills and an agent belonging to this system.
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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00047 | $0.00770 |
| Opus 5 | $0.00023 | $0.00385 |
| Sonnet 5 | $0.00009 | $0.00154 |
| Haiku 4.5 | $0.00005 | $0.00077 |
Grade A, and why
performance-testing 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.
How it starts
The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Performance testing
Running benchmarks
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
[Benchmark]
public void ToMyIndicator() => quotes.ToMyIndicator(14);
Stream pattern
[Benchmark]
public object MyIndicatorHub() => quoteHub.ToMyIndicatorHub(14).Results;
Buffer pattern
[Benchmark]
public MyIndicatorList MyIndicatorList() => new(14) { quotes };
Style comparison
[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
# Auto-detect baseline and results
pwsh detect-regressions.ps1
# Custom threshold (default 10%)
pwsh detect-regressions.ps1 -ThresholdPercent 15
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-testing is a skill published in the GitHub repository foryourhealth111-pixel/Vibe-Skills (3,235 stars, last pushed 10d ago), licensed Apache-2.0. It adds 47 tokens to every session and 770 once invoked, about $0.0002 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 2026-09-03.
