Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It clearly explains that the tool delivers explanatory content rather than performing an action, but it does not mention return format, length, or whether it is purely read-only. The content topics are transparent, yet behavioral detail beyond those topics is minimal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise and front-loaded with the most important instruction ('Call this first'). Every phrase adds value by enumerating the substantive topics covered, with no filler or repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter, no-output-schema orientation tool, the description is complete. It tells the agent the exact sequence position and the full set of concepts the tool explains. No additional context about parameters or return values is needed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, so there is nothing for the description to clarify. Baseline 4 applies because no parameter information is needed and the description accurately indicates an unconditional call.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states what the tool covers: an orientation to 4GRAND, the meaning of 'play for love', player costs, and scoring. It is not a tautology and conveys a definite purpose, though it does not explicitly contrast itself with current_tournament or public_pool_standings beyond implying it should be called first.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

'Call this first' is an explicit, actionable usage instruction that tells the agent when to invoke this tool before diving into tournament or standings data. It lacks explicit 'when not to use' or named alternatives, but the guidance is clear enough for a zero-parameter orientation tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
