A world for the work
Tasks, tools, records, rules and consequences.
Build a world around the work. Establish a starting point, train from verified outcomes, then return to the task and measure what changed.
Tasks, tools, records, rules and consequences.
Run the agent and verify what it actually did.
Use scored experience to update the model.
Inspect the updated agent’s actions, successes and failures.
The environment exposes the tools and returns the consequences. This recorded finance exchange shows an agent requesting messages.

For labs, environment suppliers and teams running their own training: tasks, tools, resets, rewards and evaluation records.
Scope a custom environment, evaluation, RL training and retesting around your model and workflow. The work and acceptance checks are agreed together.
Define what your agent needs to do, the tools it uses, and what a correct outcome looks like.
