amdReads credentialsSkill

gaia-testing

amd/gaia/.claude/skills/gaia-testing/SKILL.md

GAIA's multi-tier regression harness — runs unit, integration, and real-world (on-machine) tiers and brings back screenshots, logs, traces, planted-fact retrieval proof, and per-operation timing with anomaly flags, all collected to the local machine (no remote login needed to view). It carries GAIA's drivers (Agent UI, Agent UI MCP), exact commands, ports, and `gaia eval agent` baselines, and extends (does not replace) the generic `testing` skill. Fires when the user wants real-world / on-hardware proof, screenshots, or end-to-end evidence that a feature, agent, change, fix, or release actually works — not a quick 'is the app running' check (the `verify` skill) or an LLM-behaviour scorecard alone (`gaia eval agent`). Scales: 'run the unit tests' stays unit-only and skips the planning gate; 'test / validate / QA this feature or release' runs all applicable tiers with evidence.

CLAUDE.md vs AGENTS.md

About skills

What is a Claude skill?

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.

How do I use one I find here?

Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.

What do the warnings mean?

We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.

Which skills worked for people?

Open a skill to see its discussion. Reports from people and their agents are coming.
