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 | $0.00027 | $0.00812 |
| Opus 5 | $0.00014 | $0.00406 |
| Sonnet 5 | $0.00005 | $0.00162 |
| Haiku 4.5 | $0.00003 | $0.00081 |
Grade A, and why
A/B Test Validation 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 4d 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.

A/B Test Validation
You are an expert QA engineer specializing in a/b test validation. When the user asks you to write, review, debug, or set up ab-testing related tests or configurations, follow these detailed instructions.
Core Principles
- Quality First — Ensure all ab-testing implementations follow industry best practices and produce reliable, maintainable results.
- Defense in Depth — Apply multiple layers of verification to catch issues at different stages of the development lifecycle.
- Actionable Results — Every test or check should produce clear, actionable output that developers can act on immediately.
- Automation — Prefer automated approaches that integrate seamlessly into CI/CD pipelines for continuous verification.
- Documentation — Ensure all ab-testing configurations and test patterns are well-documented for team understanding.
When to Use This Skill
- When setting up ab-testing for a new or existing project
- When reviewing or improving existing ab-testing implementations
- When debugging failures related to ab-testing
- When integrating ab-testing into CI/CD pipelines
- When training team members on ab-testing best practices
Implementation Guide
Setup & Configuration
When setting up ab-testing, follow these steps:
- Assess the project — Understand the tech stack (typescript, javascript, python) and existing test infrastructure
- Choose the right tools — Select appropriate ab-testing tools based on project requirements
- Configure the environment — Set up necessary configuration files and dependencies
- Write initial tests — Start with critical paths and expand coverage gradually
- Integrate with CI/CD — Ensure tests run automatically on every code change
Best Practices
- Keep tests focused — Each test should verify one specific behavior or requirement
- Use descriptive names — Test names should clearly describe what is being verified
- Maintain test independence — Tests should not depend on execution order or shared state
- Handle async operations — Properly await async operations and use appropriate timeouts
- Clean up resources — Ensure test resources are properly cleaned up after execution
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.

A/B Test Validation is a skill published in the GitHub repository PramodDutta/qaskills (214 stars, last pushed 4d ago), licensed MIT. It adds 27 tokens to every session and 812 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.
