ab-test-setup

ab-test-setup is a skill for Claude Code, Codex from alecs5am/ralphy. It costs 55 tokens per session (126 once invoked), scanned A, original, Apache-2.0.

A partially restored setup guide for creating A/B tests, where two versions are compared to see which performs better.

In plain words
What is it for?
Use its remaining reference files for test templates and sample-size guidance, but restore the missing guide before relying on the skill.
Why use it?
Its main instructions are missing from the downloaded package, so it is not ready to activate until the original content is restored.

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

ab-test-setup 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.

What it actually says

A/B Test Setup

Status: body missing. The marketplace export delivered a zero-byte file for this skill on download. Re-pull from the source to restore. References under notes/skills/ab-test-setup/references/ are present and useful on their own.

Files

What ships with it

2 files 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.

Changes

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.
