ai-evaluation-patterns

ai-evaluation-patterns is a skill for Claude Code, Codex from FerroxLabs/wayland. It costs 86 tokens per session (8,226 once invoked), scanned A, original, AGPL-3.0.

A guide to evaluating AI systems using decision frameworks, implementation patterns, and reusable templates. Evaluation means measuring whether an AI system gives the expected results on defined examples and tasks.

In plain words
What is it for?
Use it to plan AI tests, choose evaluation methods, and create workflows for checking model or agent quality.
Why use it?
It helps teams replace informal impressions with repeatable checks. This makes it easier to compare changes and identify problems before or after release.

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

ai-evaluation-patterns 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 yesterday.

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 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.
