| | **V**: Variables | **V = { v₁, v₂, … }**. Measurable and manipulatable aspects of the environment relevant to the task. Observer defines these formally (e.g., position, temperature); agent may only have partial/noisy access. || | | **V**: Variables | **V = { v₁, v₂, … }**.

Agents must infer or approximate them. || | | **F**: Transformation Rules | Describe how variables evolve (physics, rules of a game, causal dynamics).

| | **C**: Constraints | Boundaries of what is possible (time, energy, error bounds, resource limits). Again, **observer’s perspective** = formal definition; **agent’s perspective** = experienced as 'difficulty' or 'failure' when limits are exceeded. \\ Constraints specify acceptable tollerances for variable values, and also limitations on the solution space (e.g. whether you are allowed to use a chatbot to help you prepare for or perform the task). || | | **C**: Constraints | Boundaries of what is possible (time, energy, error bounds, resource limits).

| | | Task Specification | The details of a task, including goal, constraints, etc. Humans often assign tasks to each other without a detailed specification; the assumption being that appropriate knowledge to fill in the missing parts already exists in the task performer. | |
