Builds the world an AI agent is tested in and everything its scenarios share, including the sub-goals they are checked on. Use after the agent has been understood and before any scenario is planned or written.
Skill Claude CodeCodex
Plans a suite of test scenarios for an AI agent and briefs the writers who write it. Use when a number of scenarios is asked for, before any is written, and whenever a round of writers has to be briefed or a finished suite checked before saving.

Reads an AI agent's source or definition and records what is verifiably true about it: its tools, rules, data and use cases. Use first, before any world is built or scenario planned.
Skill Claude CodeCodex
Writes the scenarios an AI agent is tested with, each a whole task made hard in one real way and proved against the world before it is kept. Use whenever scenarios, test cases or a suite are wanted for an agent whose contract and world have already been built, and before every scenario is submitted.

What the platform supports around an environment - how it is built, what a scenario holds, how the Scenarios tab, coverage, runs, repeats and grading work, and what cannot be done. Use to answer any question about the platform or a limit, before promising anything.
