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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the bar is lower. The description adds real context beyond them: it discloses that the response covers 'what it is not' and, notably, 'what this server can and cannot see' – useful scope transparency about the server's visibility limits.

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 front-loaded sentence naming the subject, followed by a compact colon list of the covered topics. Dense but every clause names distinct content, so nothing is wasted; only slightly list-heavy.

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?

With an output schema present, return values need not be explained, and a zero-parameter tool needs no argument guidance. The description adequately frames the content scope; the only gap is the absent routing guidance toward or away from siblings.

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, which is the baseline-4 case. There is nothing for the description to disambiguate, and the empty schema is consistent with the description.

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?

States a specific verb (overview) and resource (Life Scenario), then enumerates exactly what the overview contains: the game's purpose, boundaries, child-safety handling, server visibility, and links. It is clearly the orientation-style tool among specific lookups, though it never names a sibling to sharpen the contrast.

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?

The description never states when to call this versus find_practice_situation, get_what_to_say, or list_traits. Usage is only implied by the word 'overview' and by the fact that it is content-agnostic while its siblings presume Life Scenario context.

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