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

With no annotations, the description carries the full behavioral burden. It implies static informational content but never confirms it is read-only, whether it is static or dynamic, or what form the rules come back in (prose, structured sections) — meaningful gaps even for a zero-parameter tool.

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?

A single short sentence with zero padding, and the content list is front-loaded. It is efficient, though "the question" is left unexplained and the fragment style reads more like marketing copy than a specification.

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 simple zero-parameter documentation fetch with no output schema, the description gives an outline of the returned content but not its shape, size, or whether it must be read before other calls. Just enough to be callable, not enough to be confident.

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 takes no parameters, so there is nothing for the description to disambiguate. Baseline 4 applies.

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 names the subject matter it returns — the game question, scoring, and limits — so an agent can infer this retrieves the rules/how-to-play content. But it is written as a content blurb rather than a statement of action, with no verb ("returns", "retrieves"), and it offers no differentiation from siblings like get_tonight or get_results.

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?

There is no when-to-use guidance, no stated prerequisites, and no mention of alternatives. An agent must guess that this is the orientation call to make before register_agent or submit_picks based solely on the tool name.

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